A Tier-1 Indian primary copper refiner operating an integrated smelter plus converter plus electrolytic refinery configuration at Dahej Gujarat, Birla Copper Kanpur Uttar Pradesh, Hindustan Copper Ghatsila Jharkhand or the shuttered Sterlite Copper Tuticorin footprint sits under a five-layer cost reconciliation stack. India is structurally copper-concentrate-deficit — 90-92 percent of the concentrate requirement is CIF FOB-imported from Chile (Codelco, Antofagasta), Peru (Southern Copper), Australia (BHP), Indonesia (Freeport) and Kazakhstan (Kazakhmys) — so the first reconciliation layer is the imported concentrate bill-of-entry landed cost under Ind AS 2 with Basic Customs Duty under Chapter 26 of the Customs Tariff plus SWS 10 percent on BCD plus 5 percent IGST plus port and CHA and freight. The second layer is Section 195 read with the applicable DTAA on non-resident payment legs on the imported supply chain — critically noting that the FOB concentrate purchase consideration itself is NOT chargeable to tax in India in the hands of the overseas seller under Section 5(2) read with Section 9 (property passes at port of loading, no business connection, no PE) and Section 195 TDS does NOT apply to the concentrate purchase consideration itself; Section 195 applies to ancillary commission-brokerage, demurrage, refinery-technology-licensing under the DTAA-reduced rate. The third layer is Section 194Q buyer-side TDS at 0.1 percent on domestic Hindustan Copper Limited (HCL — PSU) concentrate purchases above the fifty lakh rupees aggregate threshold per previous year, with CBDT Circular 20/2021 confirming no PSU exemption and CBDT Circular 13/2021 governing Section 206C(1H) mutual exclusivity. The fourth layer is Rule 89(5) inverted-duty-structure refund on the 5-percent-concentrate-input-versus-18-percent-cathode-output GST delta — copper cathode HSN 7403 is NOT on the Notification 5/2017-CT (Rate) blocked list; the refund is available and is illustratively Rs 800-1,200 crore per year for a 400,000 tonnes per annum Dahej-scale refinery. The fifth layer is downstream PLI ACC Battery participation on copper foil under HSN 7410 for battery anode current collector and copper wire under HSN 7407-7408 for battery interconnect. Notably, copper is NOT in the initial CBAM scope under EU Regulation 2023/956 — no CBAM Certificate liability provision under Ind AS 37 today, though EU scope expansion is signalled for the post-2027 review. Ind AS 2 loads the three-stage inventory carrying value cascade at concentrate HSN 2603, matte-blister HSN 7401-7402 and cathode HSN 7403; Ind AS 16 capitalises the smelter, converter and refinery capex portfolio.
Build a per-plant-per-month integrated copper refiner reconciliation ledger keyed on the bill-of-entry number for the imported concentrate leg, the HCL purchase order number for the domestic concentrate leg, the smelter batch number for the concentrate-to-matte-to-blister conversion leg and the electrolytic refinery cycle number for the blister-to-cathode conversion leg. For each month, capture the imported concentrate bill-of-entry register with CIF invoice value converted at the bill-of-entry-date exchange rate, Basic Customs Duty at the notified Chapter 26 rate, Social Welfare Surcharge at 10 percent on BCD, IGST at 5 percent on CIF-plus-duty (ITC-eligible), port handling, customs house agent and cargo dwell charges, inland freight from port to refinery. For each non-resident payment leg (commission-brokerage, shipping under Section 172, demurrage-dispatch, refinery-technology-licensing), determine Section 5 chargeability, apply the DTAA article and DTAA-reduced rate under Section 90(2) more-beneficial-provision test, prepare Form 15CA and Form 15CB, file Form 27Q. For domestic HCL concentrate purchases above the fifty lakh rupees aggregate threshold per previous year, apply Section 194Q buyer-side TDS at 0.1 percent per CBDT Circular 20/2021, run Section 206C(1H) mutual-exclusivity check per CBDT Circular 13/2021. Reconcile the smelter metallurgical accounting for copper-units-in-concentrate versus copper-units-out-in-matte-and-blister, load the Ind AS 2 three-stage inventory carrying value cascade at concentrate HSN 2603, matte-blister HSN 7401-7402 and refined cathode HSN 7403. Record the by-product recovery credits for sulphuric acid captured at the double-contact double-absorption acid plant and for gold-silver-selenium-tellurium-PGM recovered from the anode slime, credit against the cathode inventory carrying value. Compute the Rule 89(5) inverted-duty-structure refund quarterly: Maximum Refund Amount = ((Turnover of inverted rated cathode supply) × Net ITC / Adjusted Total Turnover) minus tax payable on such inverted rated supply; file RFD-01A with GSTR-9 and GSTR-9C Chartered Accountant certificate. Track LME benchmark hedge positions and hedge effectiveness under Ind AS 109. Post the Ind AS 16 depreciation charge on the smelter, converter and refinery capex portfolio.
Imported concentrate origin master with mining major (Codelco Chile, Antofagasta, Southern Copper Peru, BHP Australia, Freeport Indonesia, Kazakhmys, First Quantum Panama, Glencore, Trafigura), port of loading, port of discharge (Kandla, Deendayal, Mundra), concentrate grade (copper percent, gold-silver-molybdenum by-product content), TC-RC (treatment charge and refining charge) discount, CIF-FOB delivery term, currency USD, exchange rate reference. Customs Tariff Chapter 26 HSN 2603 concentrate master with Basic Customs Duty at the notified rate, Social Welfare Surcharge at 10 percent on BCD, IGST at 5 percent. Domestic concentrate supplier master with HCL entity flag (PSU under Ministry of Mines), Section 194Q applicability from cumulative purchase greater than fifty lakh rupees per previous year, Section 206C(1H) mutual-exclusivity flag. Section 195 non-resident payment classification master with DTAA article by counterparty jurisdiction (India-Chile, India-Peru, India-Australia, India-Indonesia, India-Kazakhstan, India-Panama, India-Switzerland), DTAA-reduced rate, Section 90(2) more-beneficial-provision test, Form 15CA and Form 15CB workflow, Form 27Q quarterly return. Smelter and converter and refinery cost centre with metallurgical accounting master (copper percent in concentrate charge, matte grade, slag copper loss percent, blister copper anode-casting weight, cathode cycle throughput), by-product recovery master (sulphuric acid tonnes per tonne cathode, anode slime gold-silver-selenium-tellurium-PGM assay). Ind AS 2 inventory HSN classification master (concentrate 2603 5 percent, matte 7401 5 percent, blister 7402 5 percent, cathode 7403 18 percent, wire 7407 18 percent, wire 7408 18 percent, plate 7409 18 percent, foil 7410 18 percent). Rule 89(5) IDS refund workflow master with quarterly Net ITC accumulation, Rule 89(5) formula computation, RFD-01A filing, GSTR-9 and GSTR-9C Chartered Accountant certificate. LME benchmark hedge master with LME cash-plus-premium pricing, forward hedge positions, hedge effectiveness testing under Ind AS 109. PLI ACC Battery downstream copper foil HSN 7410 and copper wire HSN 7407-7408 supply master with beneficiary invoice, Section 194Q at beneficiary side. Ind AS 16 multi-block PPE depreciation master for smelter, converter and refinery capex portfolio with plant-life or units-of-production accounting policy tag.
A month-end integrated primary copper refiner reconciliation packet: the imported concentrate bill-of-entry register with landed cost cascade under Ind AS 2; the ancillary non-resident payment ledger with Section 195 chargeability determination and DTAA-reduced rate application under Section 90(2); the domestic HCL concentrate purchase register with Section 194Q buyer-side TDS at 0.1 percent per CBDT Circular 20/2021; the smelter and refinery metallurgical accounting reconciliation with copper-units-in-versus-copper-units-out material balance; the by-product recovery credits for sulphuric acid and anode-slime gold-silver-selenium-tellurium-PGM; the three-stage Ind AS 2 inventory carrying value cascade at concentrate HSN 2603, matte-blister HSN 7401-7402 and refined cathode HSN 7403; the Rule 89(5) inverted-duty-structure refund quarterly working and RFD-01A filing with Chartered Accountant certificate; the LME benchmark hedge position and hedge effectiveness testing under Ind AS 109; the PLI ACC Battery downstream copper foil and copper wire supply ledger with Section 194Q at the beneficiary side; the Ind AS 16 depreciation charge on the smelter, converter and refinery capex portfolio. Every material deviation flagged for the plant CFO, the plant metallurgist and the plant tax head. Multi-year continuity of the reconciliation packet produces the audit trail that a Customs Assessing Officer under Chapter 26 concentrate classification review, an Income-tax Assessing Officer under Section 194Q and Section 195 assessments, a Deputy Commissioner of State Tax under Section 54(3) read with Rule 89(5) IDS refund scrutiny, a Central Government NMET compliance audit on any captive HCL leg, a statutory auditor reviewing refinery capex depreciation and cathode inventory valuation, and a PLI ACC Battery scheme verifier at the downstream beneficiary side all expect.
A Tier-1 Indian primary copper refiner operating an integrated smelter plus converter plus electrolytic refinery configuration at Dahej Gujarat (illustrative persona: a 500,000 tonnes per annum aggregate cathode capacity across Dahej and Birla Copper Kanpur under the Aditya Birla group primary copper franchise), Ghatsila Jharkhand plus Malanjkhand Balaghat Madhya Pradesh plus Khetri Rajasthan (illustrative persona: Hindustan Copper Limited, PSU under the administrative control of the Ministry of Mines, at approximately 50,000 tonnes per annum copper-in-concentrate mining output feeding the Ghatsila refinery) or the historically operational Tuticorin footprint (illustrative persona: Vedanta Sterlite Copper at historical 400,000 tonnes per annum capacity currently under closure post the 2018 environmental order of the Tamil Nadu State Government) sits under a five-layer cost reconciliation stack. India is structurally copper-concentrate-deficit — 90-92 percent of the annual concentrate requirement is imported CIF FOB from Chile (Codelco, Antofagasta), Peru (Southern Copper, Antamina), Australia (BHP Olympic Dam, Newcrest Cadia), Indonesia (Freeport Grasberg), Kazakhstan (Kazakhmys) and Panama (First Quantum Cobre Panama) — so the first reconciliation layer is the imported concentrate bill-of-entry landed cost under Ind AS 2. The second layer is Section 195 read with the applicable Double Taxation Avoidance Agreement on non-resident payment legs on the imported supply chain — critically, the FOB concentrate purchase consideration itself is NOT chargeable to tax in India in the hands of the overseas seller (property passes at port of loading, no business connection, no permanent establishment) and Section 195 TDS does NOT apply to the concentrate purchase itself; Section 195 applies to ancillary commission-brokerage, demurrage and refinery-technology-licensing legs at the DTAA-reduced rate. The third layer is Section 194Q buyer-side TDS at 0.1 percent on domestic Hindustan Copper concentrate purchases above the fifty lakh rupees aggregate threshold per previous year, with CBDT Circular 20/2021 confirming no PSU exemption. The fourth layer is Rule 89(5) inverted-duty-structure refund on the 5-percent-concentrate-input-versus-18-percent-cathode-output GST delta — copper cathode HSN 7403 is NOT on the blocked list. The fifth layer is downstream PLI ACC Battery participation on copper foil HSN 7410 (battery anode current collector) and copper wire HSN 7407-7408 (battery interconnect). Notably, copper is NOT in the initial CBAM scope under EU Regulation 2023/956 — no CBAM Certificate liability provision today. The reconciliation discipline that stitches concentrate-bill-of-entry to Section 195 to Section 194Q to Rule 89(5) IDS refund to LME cathode dispatch to Ind AS 2 landed cost per tonne cathode is the subject of this copper cathode refinery reconciliation walkthrough.
The reconciliation in one paragraph
A Tier-1 Indian primary copper refiner must capture every rupee of the five-layer cost stack — imported concentrate landed cost under Ind AS 2 with Basic Customs Duty plus Social Welfare Surcharge plus 5 percent IGST plus port and freight, non-resident payment classification under Section 195 read with the applicable DTAA (with the critical determination that the FOB concentrate purchase consideration itself is not chargeable to tax in India in the hands of the overseas seller under Section 5(2) read with Section 9), Section 194Q buyer-side TDS at 0.1 percent on domestic Hindustan Copper concentrate purchases above the fifty lakh rupees aggregate threshold per CBDT Circular 20/2021, Rule 89(5) inverted-duty-structure refund on the 5-percent-concentrate-input-versus-18-percent-cathode-output GST delta, and downstream PLI ACC Battery copper foil and copper wire supply — against the certified end-to-end material flow from concentrate bill-of-entry at Kandla or Deendayal or Mundra port through the smelter concentrate-to-matte conversion, the Peirce-Smith or Isaconverter matte-to-blister conversion, the fire refining and anode casting, the electrolytic refinery 14-21 day cathode plating cycle, and the cathode dispatch bay LME Grade A tonnage. The core reconciliation surface is a per-plant-per-month integrated ledger keyed on the bill-of-entry number for the imported concentrate leg, the HCL purchase order number for the domestic concentrate leg, the smelter batch number for the concentrate-to-matte-to-blister conversion leg, and the electrolytic refinery cycle number for the blister-to-cathode conversion leg. The ledger holds the imported concentrate CIF invoice converted at the bill-of-entry-date exchange rate, the ancillary non-resident payment ledger with DTAA article classification and DTAA-reduced rate under the Section 90(2) more-beneficial-provision test, the domestic HCL purchase register with Section 194Q buyer-side TDS, the smelter and refinery metallurgical accounting with copper-units-in-versus-copper-units-out material balance, the by-product recovery credits for sulphuric acid captured at the double-contact double-absorption acid plant and for gold-silver-selenium-tellurium-PGM recovered from the anode slime, the Rule 89(5) inverted-duty-structure refund quarterly working and RFD-01A filing, the LME benchmark hedge position and hedge effectiveness testing under Ind AS 109, and the downstream PLI ACC Battery copper foil and wire supply ledger. Every material deviation is flagged as a month-end break for the plant CFO, the plant metallurgist and the plant tax head, with escalation to the statutory auditor and the relevant regulator where the deviation crosses the materiality threshold.
What the scenario looks like in India — a Dahej integrated copper refiner persona
The illustrative persona for this walkthrough is a Tier-1 Indian primary copper refiner operating a 400,000 tonnes per annum cathode capacity at Dahej in the Bharuch district of Gujarat, integrated with a co-located flash smelter plus Peirce-Smith converter plus fire refining and anode casting plus electrolytic tank house plus double-contact double-absorption sulphuric acid plant plus anode slime by-product refining for gold-silver-selenium-tellurium-PGM recovery, receiving concentrate through the Deendayal (Kandla) and Mundra ports on the Gujarat coast. The annual concentrate requirement at a 3.5:1 concentrate-to-cathode ratio (assuming 28.5 percent copper-in-concentrate) is approximately 1.4 million tonnes concentrate, sourced approximately 92 percent from imported origins (Chile Codelco Chuquicamata plus Antofagasta Los Pelambres plus Peru Southern Copper Toquepala plus Australia BHP Olympic Dam plus Indonesia Freeport Grasberg plus Kazakhstan Kazakhmys) at approximately 1.288 million tonnes and approximately 8 percent from domestic Hindustan Copper Limited Ghatsila supply at approximately 112,000 tonnes. The annual cathode output of 400,000 tonnes is dispatched to downstream copper wire rod continuous casters (Rautaki, Krishnan, and copper wire rod feeders), copper tube and pipe mills, and specialty copper foil mills serving the PLI ACC Battery, PLI Electronics and PLI Automotive downstream demand pools.
Illustrative Tier-1 and Tier-2 Indian primary copper refiners running the same integrated smelter-plus-converter-plus-refinery configuration include the Aditya Birla group primary copper franchise (Hindalco Dahej refinery at approximately 400,000 tonnes per annum plus Birla Copper Kanpur historically at approximately 100,000 tonnes per annum, aggregating to approximately 500,000 tonnes per annum), Hindustan Copper Limited (HCL — PSU under the administrative control of the Ministry of Mines with Ghatsila refinery in Jharkhand plus Malanjkhand mine in the Balaghat district of Madhya Pradesh plus Khetri mine in the Jhunjhunu district of Rajasthan at aggregate approximately 50,000 tonnes per annum copper-in-concentrate mining output and refinery scale) and Vedanta Sterlite Copper (historically operating the Tuticorin refinery in the Thoothukudi district of Tamil Nadu at approximately 400,000 tonnes per annum capacity currently under closure post the 2018 environmental order of the Tamil Nadu State Government following the Vedanta plant expansion protest and Central Bureau of Investigation environmental proceedings). Every one of these refiners runs the same imported concentrate bill-of-entry mechanic, the same Section 195 read with DTAA non-resident payment classification, the same Section 194Q on domestic HCL concentrate, the same Rule 89(5) inverted-duty-structure refund on the concentrate-input-versus-cathode-output GST delta, and the same downstream PLI ACC Battery copper foil and wire participation mechanic documented here.
The regulatory overlay — Section 195 DTAA, Section 194Q, Rule 89(5) IDS, Ind AS 2, Ind AS 16
Five regulatory anchors govern an integrated primary copper refiner’s month-end cost reconciliation packet. Section 195 of the Income-tax Act 1961 read with the applicable DTAA anchors the non-resident payment classification on the imported concentrate supply chain. Section 194Q read with CBDT Circular 20/2021 anchors the domestic HCL concentrate purchase TDS mechanic. Section 54(3) of the CGST Act 2017 read with Rule 89(5) of the CGST Rules 2017 anchors the inverted-duty-structure refund on the 5-percent-concentrate-input-versus-18-percent-cathode-output GST delta. Ind AS 2 anchors the three-stage sequential inventory carrying value cascade at concentrate HSN 2603, matte-blister HSN 7401-7402 and refined cathode HSN 7403. Ind AS 16 anchors the capitalisation and depreciation of the smelter, converter and refinery capex portfolio. The PLI ACC Battery scheme under the Ministry of Heavy Industries anchors the downstream copper foil and copper wire demand vector.
Section 195(1) of the Income-tax Act 1961 requires TDS deduction on any sum paid to a non-resident that is chargeable to tax in India under the provisions of the Act. The critical prior question is the Section 5(2) read with Section 9 chargeability determination — a sum is chargeable to tax in India in the hands of a non-resident only if it accrues or arises in India, or is deemed to accrue or arise in India under Section 9 (business connection under Section 9(1)(i), royalty under Section 9(1)(vi), fees for technical services under Section 9(1)(vii)). For an imported copper concentrate purchase on CIF FOB terms from an overseas mining major, the sale is completed outside India (property in the concentrate passes to the Indian buyer at the port of loading), the overseas seller has no business connection in India, no permanent establishment in India under the applicable DTAA business profits article, and no royalty or fees for technical services element — the concentrate purchase consideration itself is NOT chargeable to tax in India and Section 195 TDS does not apply. This is a materially important determination that every primary copper refiner tax head must document contemporaneously in the reconciliation packet. Section 195 does apply to ancillary non-resident payment legs — commission or brokerage paid to an overseas intermediary with an Indian business connection at the applicable India-Chile DTAA, India-Peru DTAA, India-Australia DTAA, India-Indonesia DTAA, India-Kazakhstan DTAA, India-Panama DTAA or India-Switzerland DTAA (for Glencore, Trafigura marketing arms) DTAA-reduced rate under Section 90(2); shipping payments under Section 172 special provisions with the ship agent as the deemed representative assessee; demurrage or dispatch payments to a foreign vessel operator at the Section 9(1)(vii) fees-for-technical-services classification; and refinery process technology licensing fees to Outotec, Mitsubishi Materials or Isasmelt Xstrata at the applicable DTAA royalty article rate.
Section 194Q of the Income-tax Act 1961 requires a buyer whose aggregate turnover in the immediately preceding previous year exceeded ten crore rupees to deduct TDS at 0.1 percent of the amount by which the aggregate consideration for purchase of goods from a resident seller during the previous year exceeds fifty lakh rupees. For a primary copper refiner sourcing domestic concentrate from Hindustan Copper Limited above the fifty lakh rupees aggregate threshold per previous year, Section 194Q buyer-side TDS at 0.1 percent applies at the buyer side. CBDT Circular 20/2021 dated 25 November 2021 clarifies that Section 194Q applies to purchases from Central and State Government entities and PSUs including HCL — no PSU exemption operates. The Section 194Q iron ore purchase mining lease steel reconciliation Wave 1 sibling documents the identical mechanic that transfers to HCL concentrate with only the underlying commodity changing. CBDT Circular 13/2021 dated 30 June 2021 establishes the mutual-exclusivity rule with Section 206C(1H) seller-side TCS — Section 194Q takes precedence where both apply.
Rule 89(5) of the CGST Rules 2017 read with Section 54(3) of the CGST Act 2017 permits refund of unutilised input tax credit accumulated on account of the input tax rate exceeding the output tax rate — the inverted duty structure refund. For copper cathode HSN 7403 at 18 percent output GST versus copper concentrate HSN 2603 at 5 percent input GST (both on domestic HCL supply and on imported IGST), the inversion drives ITC accumulation. Copper cathode HSN 7403 is NOT on the Notification 5/2017-CT (Rate) blocked list; the refund is available. The Rule 89(5) formula produces an illustrative Rs 800-1,200 crore per year IDS refund quantum for a 400,000 tonnes per annum Dahej-scale refinery depending on the LME cathode price, the concentrate premium plus TC/RC negotiated and the domestic-versus-import concentrate split. The Rule 89(5) inverted duty refund specialty steel India Wave 1 sibling documents the identical mechanic for specialty steel Rule 89(5) refund; the aluminium Hindalco Nalco bauxite alumina refinery cost reconciliation Wave 2 base-metals sibling documents the equivalent alumina-refinery-and-smelter Rule 89(5) position on the aluminium supply chain.
Ind AS 2 and Ind AS 16 anchor the accounting mechanics. Ind AS 2 loads the three-stage sequential inventory carrying value cascade — imported concentrate landed cost at approximately Rs 175,000-195,000 per tonne concentrate fully loaded, feeds the matte and blister inventory at HSN 7401-7402 under weighted-average cost formula, and feeds the refined cathode inventory at HSN 7403 with converter and refinery conversion cost loading (electrolytic cell electricity plus sulphuric acid make-up plus cathode starter sheet plus refractory plus O&M plus depreciation) net of by-product credits for sulphuric acid and anode-slime gold-silver-selenium-tellurium-PGM. Ind AS 16 capitalises the smelter (illustrative Rs 4,000-6,000 crore per 400,000 tonnes per annum), converter (Rs 800-1,500 crore), fire refining and anode casting (Rs 500-1,000 crore), electrolytic tank house (Rs 1,500-2,500 crore), sulphuric acid plant (Rs 800-1,500 crore) and anode slime refining (Rs 500-1,000 crore) capex portfolio depreciated over 25-30 year plant life. Copper is NOT in the initial CBAM scope under EU Regulation 2023/956 — no CBAM Certificate liability provision under Ind AS 37 today, in contrast to the aluminium CBAM exposure and the steel CBAM exposure documented in the Steel Wave 2 CBAM cornerstones.
A worked example — Dahej 400,000 TPA cathode refinery FY 2026-27 illustrative annual close
Illustrative — the following figures represent the operating pattern of a Tier-1 Indian primary copper refiner running an integrated smelter-plus-converter-plus-refinery configuration of approximately 400,000 tonnes per annum cathode capacity. Public disclosures by listed Indian copper majors do not reveal per-plant per-tonne cost stack quantum in the granularity below; cross-verify against the current LME cathode benchmark price, the current concentrate premium plus TC/RC and the current INR-USD exchange rate before action. The concentrate premium at USD 210 per tonne, LME cathode benchmark at USD 9,940 per tonne (Rs 825,000 per tonne at Rs 83 per USD), Basic Customs Duty at 5 percent, IGST at 5 percent on concentrate and 18 percent on cathode, and Section 194Q threshold at Rs 50 lakh used below are illustrative reference points intended to demonstrate the cost stack mechanic and do not represent the actual position for any specific operating year.
The Dahej integrated copper refiner closes its FY 2026-27 annual position on a 400,000 tonnes per annum cathode operational cadence. The annualised full-year picture is:

Common reconciliation breakages — five patterns that the packet must catch
First, the Section 195 chargeability determination on the imported concentrate purchase can be misapplied — a tax team unfamiliar with the Section 5(2) read with Section 9 first-principles determination sometimes withholds TDS on the FOB concentrate purchase consideration itself, converting a non-chargeable payment into a wrongly-deducted TDS with subsequent refund complications. The reconciliation packet must document the Section 5 chargeability determination contemporaneously for every foreign concentrate remittance, with the Chartered Accountant Form 15CB certificate reflecting the non-chargeability conclusion.
Second, the Section 194Q applicability on domestic HCL concentrate is sometimes missed on the assumption that PSU purchases are exempt — CBDT Circular 20/2021 explicitly negates this assumption and Section 194Q applies to HCL concentrate purchases above the fifty lakh rupees aggregate threshold per previous year. Section 206C(1H) mutual-exclusivity per CBDT Circular 13/2021 must be documented.
Third, the Rule 89(5) inverted-duty-structure refund working can under-claim where the Net ITC accumulation is computed only against the concentrate input GST without capturing the aggregate input tax pool across concentrate plus other inputs. The Rule 89(5) formula must be run against the full inverted-rated-supply-turnover and full Net ITC pool.
Fourth, the by-product credit for sulphuric acid and anode-slime gold-silver-selenium-tellurium-PGM against the cathode inventory carrying value under Ind AS 2 can be understated where the by-product revenue is recognised separately in the profit-and-loss without a corresponding cathode inventory carrying value credit — the Ind AS 2 net realisable value discipline requires the by-product credit to reduce the cathode carrying value.
Fifth, the LME benchmark hedge position and hedge effectiveness testing under Ind AS 109 can drift where the concentrate purchase pricing (LME cash-plus-premium minus TC/RC) and the cathode dispatch pricing (LME cash-plus-cathode-premium) are not hedged as a spread — the reconciliation packet must capture the spread hedge position and the Ind AS 109 hedge effectiveness testing quarterly.
How a reconciliation platform handles this
Terra Insight’s reconciliation platform loads every imported concentrate bill-of-entry, every ancillary non-resident payment ledger entry, every domestic HCL concentrate purchase order and every cathode dispatch invoice into a single unified copper-refiner reconciliation surface — reconciling the CIF landed cost against the Section 5 chargeability determination for Section 195, the Section 194Q buyer-side TDS threshold cumulative tracking, the Rule 89(5) inverted-duty-structure refund quarterly working, the smelter-refinery metallurgical accounting for copper-units-in-versus-copper-units-out, the by-product recovery credits, the LME benchmark hedge position and the downstream PLI ACC Battery copper foil and wire supply — producing the month-end audit-ready close packet documented in the reconciliation playbook for monthly close and the mode-of-failure discipline documented in the reconciliation failure mode analysis. The plant CFO receives a single per-plant-per-month dashboard covering every rupee of the imported concentrate landed cost, the ancillary non-resident TDS ledger, the domestic HCL Section 194Q compliance, the Rule 89(5) refund pipeline and the LME hedge P&L — sufficient for the Customs Assessing Officer, the Income-tax Assessing Officer, the Deputy Commissioner of State Tax on GST refund scrutiny, the statutory auditor and the PLI ACC Battery scheme verifier at the downstream beneficiary side. The steel reconciliation software India money page and the reconciliation software India product surface unpack the platform capability set in operational detail; the Section 393 payment code finder supports the migration to the new payment-code regime for the Section 194Q and Section 195 TDS deposits.

- ▸ Central Goods and Services Tax Act 2017 — Section 54(3) read with Rule 89(5) of the CGST Rules 2017 (Inverted Duty Structure refund) — Section 54(3) of the CGST Act 2017 permits a registered person to claim refund of any unutilised input tax credit at the end of any tax period where the credit has accumulated on account of the rate of tax on inputs being higher than the rate of tax on output supplies — the inverted duty structure (IDS) refund. Rule 89(5) of the CGST Rules 2017 prescribes the maximum refund formula: Maximum Refund Amount = ((Turnover of inverted rated supply of goods and services) × Net ITC / Adjusted Total Turnover) minus tax payable on such inverted rated supply of goods and services. For an integrated primary copper refiner, the inversion arises because copper concentrate under HSN 2603 attracts 5 percent GST (both domestic HCL supply and IGST on imported concentrate) as raw material input, while refined copper cathode under HSN 7403 attracts 18 percent GST as finished-goods output; the accumulated unutilised ITC on the 5 percent-input-vs-18 percent-output delta is refundable subject to the Rule 89(5) formula. The Notification 5/2017-CT (Rate) list of goods where IDS refund is blocked does NOT include copper cathode HSN 7403 — the IDS refund is available and is a material cash-flow input for the Indian primary copper refiner. The typical annual refund quantum for a 400,000 tonnes per annum Dahej-scale refinery is illustratively in the Rs 800-1,200 crore range depending on the LME cathode price, the concentrate landed cost and the domestic-versus-import concentrate split.
- ▸ Income-tax Act 1961 — Section 195 read with the applicable Double Taxation Avoidance Agreement (DTAA) and CBDT circulars — Section 195(1) of the Income-tax Act 1961 requires any person responsible for paying to a non-resident any sum chargeable under the provisions of the Act (excluding salary under Section 192) to deduct tax at source at the rates in force at the time of credit or payment, whichever is earlier. For an integrated primary copper refiner importing concentrate on CIF Free-On-Board (FOB) purchase terms from an overseas mining major (Codelco Chile, Antofagasta Chile, Southern Copper Peru, BHP Australia, Freeport-McMoRan, Glencore, Trafigura), the concentrate purchase invoice consideration is typically not chargeable to tax in India in the hands of the overseas seller under Section 5(2) read with Section 9(1) — the sale is completed outside India (property in the concentrate passes to the Indian buyer at the FOB port of loading), no business connection in India, no permanent establishment in India, no royalty or fees for technical services element — and therefore Section 195 TDS does not apply to the concentrate purchase consideration itself. Section 195 TDS DOES apply to (a) commission or brokerage paid to an overseas intermediary if the intermediary has a business connection in India; (b) shipping or logistics service payments to a non-resident carrier where Section 172 special provisions do not apply; (c) demurrage or dispatch payments to a foreign vessel operator; (d) technical services or consultancy fees for refinery process technology licensing paid to an overseas licensor (Fees for Technical Services under Section 9(1)(vii)); and (e) royalty payments for concentrate testing or metallurgical process patents licensed from an overseas licensor (Royalty under Section 9(1)(vi)). Each such non-resident payment leg is classified against the applicable India-Chile DTAA, India-Australia DTAA, India-USA DTAA or India-Switzerland DTAA (Glencore, Trafigura), with the DTAA-reduced withholding rate applied against the domestic Section 195 rate under the more-beneficial-provision test in Section 90(2).
- ▸ Income-tax Act 1961 — Section 194Q buyer-side TDS on domestic concentrate purchase and Section 206C(1)(vi) TCS mutual exclusivity — Section 194Q of the Income-tax Act 1961 (introduced by Finance Act 2021, effective 1 July 2021) requires a buyer whose aggregate turnover in the immediately preceding previous year exceeded ten crore rupees to deduct tax at source at 0.1 percent of the amount by which the aggregate consideration for purchase of goods from a resident seller during the previous year exceeds fifty lakh rupees. For an Indian primary copper refiner (Hindalco Dahej, Birla Copper Kanpur) sourcing domestic concentrate from Hindustan Copper Limited (HCL — Public Sector Undertaking under the administrative control of the Ministry of Mines, operating the Ghatsila refinery in Jharkhand plus the Malanjkhand and Khetri mines in Madhya Pradesh and Rajasthan) above the fifty lakh rupees aggregate threshold per previous year, Section 194Q(3) TDS at 0.1 percent applies at the buyer-side. CBDT Circular 20/2021 dated 25 November 2021 clarifies that Section 194Q applies to purchases from Central and State Government entities and PSUs including HCL — no PSU exemption operates. Section 206C(1)(vi) of the Income-tax Act 1961 requires a seller of scrap to collect TCS at 1 percent from the buyer at the time of debit of the amount to the account of the buyer or at the time of receipt, whichever is earlier — copper concentrate itself is NOT scrap (concentrate is a raw material intermediate; scrap is HSN 7404 copper scrap). CBDT Circular 13/2021 dated 30 June 2021 establishes the mutual-exclusivity rule: where a transaction is covered by both Section 194Q (buyer-side TDS on goods purchase) and Section 206C(1H) (seller-side TCS on goods sale where the seller's turnover exceeds ten crore rupees and the buyer's turnover is below the Section 194Q buyer turnover threshold), Section 194Q takes precedence and Section 206C(1H) does not apply. The [Section 194Q iron ore purchase mining lease steel reconciliation](/insights/section-194q-iron-ore-purchase-mining-lease-steel-industry-cost-reconciliation/) sibling documents the identical Section 194Q compliance mechanic that applies to HCL concentrate purchases with only the underlying commodity changing.
- ▸ First Schedule to the Customs Tariff Act 1975 — Chapter 26 (Ores, Slag and Ash) and Chapter 74 (Copper and Articles thereof) — Chapter 26 of the First Schedule to the Customs Tariff Act 1975 classifies copper ores and concentrates under HSN 2603 with Basic Customs Duty at 2.5-5 percent (concentrate at the applicable rate under the current Customs Tariff Notification, plus Social Welfare Surcharge at 10 percent on BCD, plus IGST at 5 percent under GST classification for HSN 2603, plus port and CHA and freight). Chapter 74 classifies refined copper and copper alloys — copper matte and cement copper under HSN 7401; unrefined copper (blister copper) and copper anodes for electrolytic refining under HSN 7402; refined copper cathode and unwrought copper (electrolytic tough pitch ETP, fire-refined tough pitch FRTP, oxygen-free high conductivity OFHC) under HSN 7403 at 18 percent GST; copper waste and scrap under HSN 7404 at 18 percent GST; copper master alloys under HSN 7405; copper powder and flakes under HSN 7406; copper bars, rods and profiles under HSN 7407 at 18 percent GST; copper wire under HSN 7408 at 18 percent GST; copper plates, sheets and strip under HSN 7409 at 18 percent GST; copper foil under HSN 7410 at 18 percent GST. The concentrate-to-cathode HSN progression 2603 → 7401 → 7402 → 7403 tracks the smelter-converter-refinery process; the cathode-to-wire progression 7403 → 7407 → 7408 tracks the downstream wire and rod conversion. The 5 percent GST rate on concentrate versus the 18 percent GST rate on cathode establishes the Rule 89(5) inverted-duty-structure refund entitlement.
- ▸ Ind AS 2 (Inventories) — Companies (Indian Accounting Standards) Rules 2015 — Ind AS 2 governs the accounting for inventories. For an integrated primary copper refiner, the imported concentrate landed cost comprises (a) the CIF purchase invoice value from the overseas mining major converted at the applicable exchange rate on the bill-of-entry date; (b) Basic Customs Duty at the notified rate under Chapter 26 of the Customs Tariff; (c) Social Welfare Surcharge at 10 percent on BCD; (d) IGST at 5 percent on the CIF-plus-duty value (available as ITC under GST — not a cost); (e) port handling, customs house agent, cargo dwell and warehouse charges; (f) inland freight from Kandla, Deendayal or Mundra port to the Dahej refinery; and (g) demurrage or detention where applicable. The domestic HCL concentrate landed cost comprises the invoice value plus Section 194Q buyer-side TDS applied at 0.1 percent above the fifty lakh rupees aggregate threshold (TDS deducted from the seller payment, not added to landed cost) plus inland freight plus 5 percent input GST (ITC-eligible). The smelter conversion cost adds coal or gas fuel, oxygen, silica flux, lime, refractory, energy, labour and depreciation to produce blister copper at HSN 7402; the converter and refinery conversion cost adds electrolytic cell electricity, sulphuric acid make-up, cathode starter sheets, refractory and depreciation to produce refined copper cathode at HSN 7403. The three-stage inventory carrying value cascade — concentrate at HSN 2603, blister at HSN 7402, cathode at HSN 7403 — is loaded under weighted-average cost formula against the metallurgical accounting for copper units in and copper units out at each stage, with by-product credits for sulphuric acid, gold and silver recovered from the electrolytic anode slime credited back to the cathode inventory carrying value.
- ▸ PLI ACC Battery Storage Scheme — Rs 18,100 crore, Ministry of Heavy Industries (MHI) — The Production Linked Incentive (PLI) scheme for National Programme on Advanced Chemistry Cell (ACC) Battery Storage was approved by the Union Cabinet on 12 May 2021 with an outlay of Rs 18,100 crore, targeting 50 GWh of ACC battery manufacturing capacity in India by 2030 across selected beneficiaries (LG Energy Solution India, Reliance New Energy, Rajesh Exports, Ola Electric). Copper enters the ACC battery supply chain as (a) battery-grade copper foil under HSN 7410 (thickness 6-15 micron) used as the anode current collector — a lithium-ion cell uses aluminium foil at the cathode current collector and copper foil at the anode current collector; (b) copper wire and busbar under HSN 7407 and 7408 for cell-to-cell interconnect, module wiring and pack-level busbar; and (c) copper alloy contacts and connectors for the battery management system. Primary copper refiners do not directly receive PLI ACC Battery incentive (the scheme incentivises the cell manufacturer beneficiary), but downstream integration into the battery supply chain represents a material new demand vector for the primary copper franchise alongside traditional building-wire (HSN 7407), power-cable, transformer-winding and telecom-cable demand. Ind AS 115 revenue recognition for the copper foil or copper wire sale to the ACC beneficiary is a straightforward performance-obligation-satisfied-on-delivery model; Section 194Q buyer-side TDS applies at the ACC beneficiary side above the fifty lakh rupees aggregate threshold. The Ministry of Heavy Industries additionally operates the PLI Automotive and PLI Electronics schemes that create ancillary demand for copper wire and foil in the electric vehicle powertrain (motor winding, traction battery interconnect) and electronic components (printed circuit board copper laminate, semiconductor packaging) supply chains.
