Chemical Inverted-Duty Refund Calculator with Chapter 27 Blockage
Per plant, per month. Enter the plant's output turnover broken by HSN chapter — Chapter 15 (BLOCKED per Notification 09/2022-CT (Rate)), Chapter 27 (BLOCKED per Notification 09/2022-CT (Rate)), Chapter 28 inorganic chemicals (includable), Chapter 29 organic chemicals (includable), mixed Chapter 30-39 other output (includable) — along with nil-rated turnover, zero-rated turnover (exports under LUT/bond), the tax payable on inverted-rated supply, and the input ITC broken by HSN chapter — Ch 27 solvents + power + fuel, Ch 15 oleochemical inputs, Ch 28/29 chemical intermediates, Ch 39 packaging, other input goods, input services (excluded per Notification 14/2022 amended formula), capital goods (excluded per Notification 14/2022 amended formula). The tool computes refund-eligible output turnover, refund-eligible Net ITC, adjusted total turnover, the maximum Rule 89(5) refund quantum per plant-month, the excluded-ITC audit trail line by line, and the annualised Chapter 27 blockage working-capital impact for the CFO's cash-flow committee. Twelve-plus plant-months per session supported, chronological plant-month ledger, per-plant-month expanded audit trail.
Illustrative — outputs are directional and based on the amended Rule 89(5) formula per CBIC Notification 14/2022-CT dated 05-July-2022 and the Chapter 27 + Chapter 15 output-side carve-out per CBIC Notification 09/2022-CT (Rate) dated 13-July-2022 (effective 18-July-2022). The Chapter 27 blockage is PERMANENT and UNCONDITIONAL since 18-July-2022. Verify current input GST rates by HSN chapter, current Notification 09/2022 + 14/2022 applicability to your plant's supply mix, and any state-specific position (Gujarat GIDC PCPIR incentives, Maharashtra MIDC subsidies, AP APIIC petchem incentives) with your indirect-tax head, your GST consultant and the CBIC's post-56th-Council FAQ series before uploading any actual RFD-01 filing. The tool does not constitute tax, GST, refund or legal advice.
Chapter 27 + Chapter 15 output-side block — CBIC Notification 09/2022-CT (Rate) dated 13-July-2022, effective 18-July-2022, invoked clause (ii) of the first proviso to Section 54(3) of the CGST Act 2017 and permanently BLOCKS the Section 54(3) inverted-duty refund on HSN Chapter 15 output (animal and vegetable fats and oils — HSN 1501-1522, the Agro-cluster edible-oil block affecting Adani Wilmar and Patanjali Foods) and HSN Chapter 27 output (mineral fuels, mineral oils and products of their distillation — HSN 2707 aromatics + coal-tar oils, HSN 2710 petroleum oils + distillates, HSN 2711 petroleum gases + LPG, HSN 2713 petroleum coke + bitumen residues, HSN 2714 bitumen + asphalt, HSN 2715 bituminous mixtures). The block is permanent and unconditional. For petrochemical + refinery-downstream operations — Deepak Phenolics Dahej, GACL Vadodara, ONGC Petro-additions Dahej, IOCL Vadodara + Haldia, Reliance Jamnagar downstream converters — this is the single largest structural working-capital constraint on the sub-segment.
Cross-cluster mechanic — the same Notification 09/2022 statutory anchor drives the Chapter 15 edible-oil block on the Agro cluster (Adani Wilmar, Patanjali Foods) and the Chapter 27 solvent block on the Pharma API cluster (Divi's Laboratories, Aurobindo API divisions, Laurus Labs). The chemicals context is the LARGEST cash-flow surface for the sub-segment because petrochemical + refinery-downstream operations are the deepest Chapter 27 output exposure in the Indian economy. See the sibling Agro and Pharma tools for the parallel implementations.
Rule 89(5) refund computation — per plant per month
One row per plant per tax-period month. This is the row that ties to the plant's monthly RFD-01 filing on the GST portal. Max Refund = (Refund-eligible output turnover × Refund-eligible Net ITC ÷ Adjusted total turnover) − Tax payable on inverted-rated supply. Refund-eligible output turnover excludes Ch 15 + Ch 27 (permanent block per Notification 09/2022).
| Plant | Month | Refund-eligible output | Adj. total turnover | Refund-eligible Net ITC | Pro-rata Net ITC | Tax payable | Max Refund | Flags | |
|---|---|---|---|---|---|---|---|---|---|
| No plant-months added. Enter the first plant-month above. | |||||||||
Excluded ITC audit trail — per plant per month
The three carve-outs that separate the plant's month-total refund quantum from what a hypothetical un-blocked refund would have been — input services excluded per Notification 14/2022-CT amended formula, capital goods excluded per Notification 14/2022-CT amended formula, plus the Ch 15 + Ch 27 output-side blockage per Notification 09/2022-CT (Rate) which suppresses the refund-eligible output turnover proportionally. Keep this table alongside the RFD-01 filing for the audit committee and the GST officer's verification questionnaire.

Chapter 27 blockage — annualised working-capital impact
The Chapter 27 output-side blockage per Notification 09/2022 is permanent and unconditional. The proxy monthly impact = (Ch 27 output ÷ Adjusted total turnover) × Refund-eligible Net ITC — the refund quantum that would have accrued for Chapter 27 output if it were not blocked. Annualise × 12 for the CFO's rolling working-capital view. For a petrochemical anchor beneficiary, this typically sits in the Rs 200-400 crore per year per beneficiary band.

Chapter 27 is the largest cash-flow reconciliation surface on India's petrochemical and specialty-chemicals close
CBIC Notification 09/2022-CT (Rate) dated 13-July-2022, effective 18-July-2022, invoked clause (ii) of the first proviso to Section 54(3) of the CGST Act 2017 and permanently barred refund of unutilised ITC on inverted duty structure for goods under HSN Chapter 15 (animal and vegetable fats and oils) and HSN Chapter 27 (mineral fuels, mineral oils and products of their distillation). Layered onto that, CBIC Notification 14/2022-CT dated 05-July-2022 amended the Net ITC definition in Rule 89(5) prospectively — refund applications filed on or after 05-July-2022 exclude the ITC availed on input services and on capital goods from the Net ITC numerator, mirroring the constitutional position in Union of India v. VKC Footsteps India Pvt Ltd (2021) 10 SCC 674. For every Indian specialty chemicals manufacturer — SRF Ltd at Bhiwadi and Dahej (fluorochemicals + refrigerants + specialty polymer films), Aarti Industries at Vapi and Jhagadia (benzene intermediates + specialty nitro-aromatics), Deepak Nitrite at Dahej and Nandesari (phenol-acetone-DASDA), Vinati Organics at Mahad (IBB and ATBS global leadership), Atul Ltd at Valsad (Lalbhai group dyes and aromatics), Navin Fluorine at Surat (Mafatlal group fluorochemistry + CDMO), PI Industries at Panoli and Jambusar (agrochem CSM and CDMO), GHCL at Sutrapada (soda ash), Fine Organic Industries at Ambernath and Dombivli (oleochemical additives), Rossari Biotech at Silvassa (home care + textile chemicals), Anupam Rasayan at Sachin and Jhagadia (life-science specialty), Gujarat Fluorochemicals GFL (fluoropolymers + EV battery chemicals), Neogen Chemicals at Vadodara (bromine + lithium electrolytes), Alkyl Amines Chemicals at Solapur and Balaji Amines — and every petrochemical + refinery downstream anchor — Deepak Phenolics Dahej phenol complex, GACL Vadodara, ONGC Petro-additions Dahej, IOCL Vadodara + Haldia refineries, HPCL Vishakh, Reliance Jamnagar downstream converters — the two overlays now define the monthly RFD-01 reconciliation surface.
The Chapter 27 blockage is the more structural of the two. HSN Chapter 27 sweeps in HSN 2707 (aromatics and coal-tar oils — the BTX starts for benzene, toluene and xylene chemistry), HSN 2710 (petroleum oils and light distillates — naphtha for cracker feedstock, gasoline, kerosene, diesel fuels, lubricating oils, base oils for specialty additives), HSN 2711 (petroleum gases and LPG — propane, butane, ethane, propylene and butene feedstocks), HSN 2713 (petroleum coke and bitumen residues — carbon black and specialty coke feedstock), HSN 2714 (bitumen and asphalt) and HSN 2715 (bituminous mixtures). For every anchor beneficiary in the Dahej PCPIR (Petroleum Chemicals and Petrochemical Investment Region), Nakkapalli petchem cluster, Vishakhapatnam petchem downstream, Haldia West Bengal petchem, Cuddalore-Panruti Tamil Nadu SIPCOT petchem downstream, annual Chapter 27 output turnover typically sits in the Rs 15,000-25,000 crore range per anchor beneficiary. At a blended input GST rate of ~14-16 percent across Chapter 27 solvent inputs, power, fuel, Chapter 28/29 chemical intermediates and Chapter 39 packaging, the permanent input GST accumulation attributable to Chapter 27 output that is blocked-from-refund routinely reaches Rs 200-400 crore per year per anchor beneficiary. That accumulated ITC does not become worthless — it offsets output tax on non-blocked (Ch 28/29) supplies from the same GSTIN — but it never converts to a bank credit and its economic value depreciates against the plant's real cost of capital.
The reconciliation surface behind the RFD-01 is deep and unforgiving. Every plant-month refund file must reconcile against the electronic credit ledger balance at tax-period end, against the GSTR-3B Table 4 ITC availed lines, against the GSTR-2B ITC visibility for the month, against the plant's SAP FI or Oracle Fusion GL entries for input purchases, against the plant's Fixed Asset Register for capital-goods ITC, against the plant's Service Master for input services ITC, and against the HSN-wise inward and outward supply schedules that flow into Statement 1A of the RFD-01. Any misclassification — a Chapter 29 organic intermediate mis-tagged as Chapter 27 (which would understate the refund-eligible Net ITC), a mixed-load export invoice split across two HSN chapters mis-consolidated (which would misroute Rule 89(4) vs Rule 89(5) treatment), a Chapter 27 output invoice recorded net of freight (which would understate the blocked output), a service invoice for CDMO / CRAMS toll manufacturing consulting booked as goods on the finance side but as services on the GST side (which would misclassify Notification 14/2022 treatment) — will surface in the GST officer's verification questionnaire and can convert into an RFD-03 deficiency memo, deferring the sanction. On top of the refund reconciliation sits the TDS-tax overlay under the Income-tax Act 2025 — Section 194Q code 1031 (0.1 percent TDS on aggregate purchase of goods above Rs 50 lakh per PAN per FY) applies to the plant's chemical input purchases from vendors above threshold and to downstream paint / FMCG / auto buyers procuring from Aarti / Deepak Nitrite / SRF / Vinati / Atul / GHCL etc.; Section 206C(1H) applies to the manufacturer's chemical output sales above threshold with CBDT Circular 13/2021 mutual-exclusion; Section 194C applies to job-work toll manufacturing arrangements under Section 143 CGST + Rule 55 CGST + Rule 45 CGST + quarterly ITC-04 (as in Navin Fluorine's CDMO 3-stage synthesis at Surat and Tarapur, PI Industries' CSM/CDMO at Jambusar, Anupam Rasayan at Sachin, Suven Life Sciences); Section 194J code 1005 applies to consulting and technology-transfer engagements. All of these flow into the same underlying purchase and payment ledger that feeds the RFD-01 numerator.
TransactIG operationalises the end-to-end Rule 89(5) reconciliation at chemicals-manufacturer scale — the electronic credit ledger against GSTR-3B against GSTR-2B against the plant's SAP FI or Oracle Fusion purchase register against the HSN-tagged output turnover register (Ch 15, Ch 27, Ch 28, Ch 29, Ch 30-39 mix) against the Fixed Asset Register against the Service Master against the plant-month RFD-01 filing against the RFD-04 provisional 90 percent sanction (Section 54(6) + Rule 91) against the RFD-06 final sanction against bank credit — plant-by-plant, HSN-chapter-by-chapter, month-by-month, line-by-line. The excluded-ITC audit trail is produced as a first-class artefact for the audit committee and for the GST officer's verification questionnaire. The Chapter 27 blockage annualised working-capital impact is surfaced as a rolling CFO metric next to the Agro Ch 15 wall and the Pharma Ch 27 solvent wall. ISO 27001:2022, AWS Mumbai, DPDP Act 2023 aligned, implementation two to four weeks.

Frequently Asked Questions
What is Rule 89(5) inverted-duty refund and why is it the single largest cash-flow reconciliation surface on an Indian specialty chemicals manufacturer's monthly close? +
Rule 89(5) of the Central Goods and Services Tax Rules 2017 operationalises Section 54(3) of the CGST Act 2017, which grants a registered person a claim to refund of unutilised input tax credit (ITC) accumulated where the output tax rate on the outward supply is lower than the input tax rate on the inputs used to make that supply — the Inverted Duty Structure (IDS) refund. The formula, as amended by CBIC Notification 14/2022-CT dated 05-July-2022 and applicable to all refund applications filed on or after that date, is Maximum Refund Amount = {(Turnover of inverted-rated supply of goods) × Net ITC ÷ Adjusted Total Turnover} minus Tax payable on such inverted-rated supply. The constitutional anchor for the amended formula is the Supreme Court judgment in Union of India v. VKC Footsteps India Pvt Ltd (2021) 10 SCC 674, which upheld the exclusion of input services ITC from Rule 89(5) refund. For an Indian specialty chemicals manufacturer — SRF Ltd at Bhiwadi and Dahej, Aarti Industries at Vapi and Jhagadia, Deepak Nitrite at Dahej and Nandesari, Vinati Organics at Mahad, Atul Ltd at Valsad, Navin Fluorine at Surat, PI Industries at Panoli and Jambusar, GHCL at Sutrapada, Fine Organic Industries at Ambernath and Dombivli, Rossari Biotech at Silvassa, Anupam Rasayan at Sachin and Jhagadia — the input GST rate on chemical inputs, packaging, solvents and power ranges 12-18 percent, while the output GST rate on Ch 28 inorganic chemicals and Ch 29 organic chemicals is a flat 18 percent with only marginal inversion on specific specialty grades. But the reconciliation surface is deep and unforgiving because of two overlays. First, CBIC Notification 09/2022-CT (Rate) permanently blocks refund on HSN Chapter 27 and Chapter 15 output. Second, CBIC Notification 14/2022-CT amended the Net ITC to goods-only. The tool operationalises both overlays plant-by-plant, HSN-chapter-by-chapter, month-by-month, so the RFD-01 preparer has a clean line-item computation and audit trail for every plant-month filed on the GST portal.
How does CBIC Notification 09/2022-CT (Rate) dated 13-July-2022 (effective 18-July-2022) BLOCK the Chapter 27 output from the inverted-duty refund, and why is this the single largest structural constraint on the petrochemical and refinery-downstream sub-segment? +
CBIC Notification 09/2022-CT (Rate) dated 13-July-2022, effective 18-July-2022, invoked clause (ii) of the first proviso to Section 54(3) of the CGST Act 2017 to notify a list of goods where NO refund of unutilised ITC on account of inverted duty structure shall be allowed. Two chapter blocks were notified. First, HSN Chapter 15 — animal and vegetable fats and oils (the edible-oil sub-vertical, which sits primarily on the Agro cluster but also touches oleochemical converters such as Fine Organic Industries where a portion of the palm-oleyl chemistry starts in Ch 15). Second, HSN Chapter 27 — mineral fuels, mineral oils and products of their distillation, which is THE central anchor of the Chemicals cluster because it sweeps in the entire petrochemical and refinery-downstream chain. HSN 2707 (aromatics and coal-tar oils — the feedstock for benzene, toluene and xylene BTX chemistry that starts every Aarti Industries or Deepak Nitrite process), HSN 2710 (petroleum oils and light distillates — naphtha, gasoline, kerosene, diesel fuels, lubricating oils), HSN 2711 (petroleum gases and LPG), HSN 2713 (petroleum coke and bitumen residues — the feedstock for carbon black and specialty coke chemistry), HSN 2714 (bitumen and asphalt) and HSN 2715 (bituminous mixtures) all sit under Chapter 27 and are permanently barred from IDS refund. For a petrochemical downstream operation — Deepak Phenolics at Dahej, GACL at Vadodara, ONGC Petro-additions at Dahej, Deepak Nitrite's Dahej phenol complex, IOCL Vadodara — annual Chapter 27 output turnover in the Rs 15,000-25,000 crore range per anchor beneficiary translates to permanent input GST accumulation in the Rs 200-400 crore per year per beneficiary blocked-from-refund range. The blockage is permanent and unconditional and applies at the output-turnover level. This tool separates the Ch 27 (and Ch 15) output turnover out of the refund-eligible output turnover, carves the excluded quantum out of the Max Refund computation, and annualises the working-capital impact of the Ch 27 block as a distinct line for the CFO's cash-flow committee.
How does CBIC Notification 14/2022-CT dated 05-July-2022 change the Net ITC formula for Rule 89(5), and what does that mean in cash terms for a chemical manufacturer? +
CBIC Notification 14/2022-CT dated 05-July-2022 amended the definition of Net ITC in Rule 89(5) prospectively — refund applications filed on or after 05-July-2022 must use the amended formula; applications filed before that date use the pre-amendment definition. The amendment carved out two large ITC pools from Net ITC. First, the ITC availed on input services is excluded from Net ITC for Rule 89(5) purposes. Second, the ITC availed on capital goods is excluded from Net ITC for Rule 89(5) purposes. Only the ITC availed on inputs — goods — flows into the Net ITC numerator of the refund formula. This mirrors the constitutional position reasoned by the Supreme Court in Union of India v. VKC Footsteps India Pvt Ltd (2021) 10 SCC 674, which upheld the exclusion of input services from Rule 89(5) refund. For a large specialty chemicals plant, the cash impact is material. A single Vapi-Ankleshwar or Jhagadia-Dahej facility may book ITC of Rs 30-60 crore per month on input services (contract research, technology transfer for CDMO/CRAMS engagements, effluent-treatment plant consulting, environmental compliance retainers, USFDA / EMA / Ecocert audit fees for chemicals-cluster export customers, distribution logistics into Kandla and Hazira ports, warehouse rentals, professional fees under Section 194J code 1005) and Rs 15-30 crore per month on capital goods (reactors, distillation columns, chromatography units, packaging lines, quality-control instrumentation, ETP upgrades). Under the amended formula, none of that ITC is refundable under Rule 89(5) even though it is validly availed and reduces the plant's output-tax liability on non-inverted supplies. The refund is available only on the goods ITC (Ch 27 solvents + power + fuel used as inputs, Ch 15 oleochemical inputs where applicable, Ch 28/29 chemical intermediates, Ch 39 packaging, other input goods). This tool applies the amended formula strictly — input services ITC and capital goods ITC are captured for the audit trail but are subtracted out of the refund-eligible Net ITC.
Which HSN codes fall under Chapter 27 for refund blockage, and how do they map to the petrochemical + refinery-downstream feedstock chain? +
HSN Chapter 27 covers mineral fuels, mineral oils and products of their distillation, bituminous substances and mineral waxes. Six HSN heads sweep in the entire petrochemical and refinery-downstream feedstock chain. HSN 2707 covers aromatics and coal-tar oils — heavy aromatic solvents, benzene, toluene, xylene (BTX) intermediates. These are the process starts for benzene-intermediate specialty chemistry that anchors Aarti Industries and Deepak Nitrite as India's DASDA + phenol + speciality nitro-aromatic leaders. HSN 2710 covers petroleum oils and light distillates — naphtha (the primary olefin feedstock into GACL, ONGC Petro-additions Dahej and Reliance Jamnagar's cracker complexes), gasoline, kerosene, diesel fuels, lubricating oils, base oils for specialty additives. HSN 2711 covers petroleum gases and LPG — propane, butane, ethane, propylene and butene feedstocks. HSN 2713 covers petroleum coke and bitumen residues — carbon black feedstock and specialty coke inputs into GHCL and other alkali-metal chemistry. HSN 2714 covers bitumen and asphalt. HSN 2715 covers bituminous mixtures based on natural asphalt, natural bitumen, petroleum bitumen, mineral tar or mineral tar pitch. For every chemical manufacturer that outputs Chapter 27 goods — the entire petrochemical downstream from Dahej PCPIR (Petroleum Chemicals and Petrochemical Investment Region), Nakkapalli (Andhra Pradesh) petchem cluster, Vishakhapatnam petchem downstream, Haldia (West Bengal), Cuddalore-Panruti (Tamil Nadu SIPCOT petchem downstream) — the CBIC Notification 09/2022 output-side block permanently caps the Rule 89(5) refund quantum. The tool captures the plant's Chapter 27 output turnover as an explicit input line, subtracts it from the refund-eligible output turnover, and displays the annualised Chapter 27 blockage impact so the CFO has a rolling monthly and annualised view of the trapped working capital.
What is the working-capital impact of the Chapter 27 blockage on the petrochemical + refinery-downstream sub-segment, and how does it compare to the sibling Chapter 15 edible-oil block on Agro (Adani Wilmar, Patanjali Foods) and the Chapter 27 solvent block on Pharma API (Divi's Laboratories)? +
The Chapter 27 output-side blockage per CBIC Notification 09/2022 is the single largest structural working-capital constraint on the Indian petrochemical and refinery-downstream sub-segment. At anchor-beneficiary scale — Deepak Phenolics at Dahej, GACL Vadodara, ONGC Petro-additions Dahej, IOCL Vadodara + Haldia, HPCL Vishakh, Reliance Jamnagar and their downstream specialty converters — annual Chapter 27 output turnover typically sits in the Rs 15,000-25,000 crore range per anchor beneficiary. At an average blended input GST rate of ~14-16 percent across Chapter 27 solvent inputs, power and fuel, Chapter 28/29 chemical intermediates and Chapter 39 packaging, and given the effective inversion delta on Chapter 27 output at 18 percent GST versus higher-input-rate mix, the permanent input GST accumulation that is blocked-from-refund routinely reaches Rs 200-400 crore per year per anchor beneficiary. That trapped ITC does not become worthless — it can be used to offset output tax on non-blocked (Ch 28/29) supplies from the same GSTIN — but it never converts to a bank credit and its economic value depreciates against the plant's real cost of capital. The sibling mechanic on Agro is Chapter 15 (edible oils — HSN 1501-1522) affecting Adani Wilmar and Patanjali Foods on the crude-palm-oil crush + refine chain; the sibling mechanic on Pharma API is a Chapter 27 solvent block at input side affecting Divi's Laboratories at Bollaram, Aurobindo API divisions, Laurus Labs at Vishakhapatnam. Same Notification 09/2022 statutory anchor. Different HSN scope, different chain position, identical constitutional and procedural mechanic. This calculator is the Chemicals-cluster instantiation of the same underlying reconciliation surface — the tool annualises the Ch 27 blockage impact per plant-month so the CFO has a directly comparable cash-flow metric next to Agro's Ch 15 wall and Pharma's Ch 27 solvent wall.
