A Tier-1 Indian specialty fluoro-intermediate producer operating a manufacturing block within the Dahej Special Economic Zone in Gujarat must reconcile its Net Foreign Exchange position on a five-year cumulative basis per Rule 30 of the SEZ Rules 2006. The block period runs from FY 2022-23 through FY 2026-27. The formula NFE equals A minus B measures cumulative FOB exports (A) against cumulative CIF imports plus foreign-exchange outgoings on royalty, dividend, interest on external commercial borrowings and other items (B). The block gate is binary — cumulative NFE at end of Y5 must be positive. A negative cumulative outcome triggers Development Commissioner enforcement action under the Foreign Trade (Development and Regulation) Act 1992 and retrospective denial of Section 26 SEZ Act exemptions and drawbacks availed over the block period. In parallel, the reconciliation surface must handle the customs-duty computation on any Domestic Tariff Area sale from the SEZ block per Rule 46 of the SEZ Rules 2006, the anti-double-benefit position that RoDTEP is not applicable to SEZ shipments, and the Section 54(3) CGST refund route via the zero-rated-supply proviso 1(i) for any accumulated ITC where the SEZ duty exemption was not availed.
Build a year-on-year cumulative NFE workbook keyed on the SEZ unit's Letter of Approval and Development Commissioner registration. Extract A — the FOB value of exports — from the year-wise Softex forms, shipping bills, and eBRC (electronic Bank Realisation Certificate) receipts consolidated per financial year and per Authorised Dealer bank. Extract B — the CIF value of imported inputs and capital goods — from the year-wise Bills of Entry filed at the SEZ Customs office plus the year-wise foreign-exchange outgoings on royalty, know-how, dividend, interest on ECBs and other Rule 30(1)(b) items sourced from the RBI Liberalised Remittance Scheme and Authorised Dealer bank statements. Compute NFE per year and cumulative NFE Y1 through Y5. Flag the trajectory — front-loaded capital-goods import in Y1 and Y2 typically produces negative annual NFE with cumulative recovery from Y3 as the export book ramps. Run a Rule 46 DTA sale duty computation per DTA transfer with the customs-duty layers (BCD plus SWS plus IGST plus any compensation cess) and treat the DTA sale value as an outgoing in B for the NFE workbook. Separately track the Section 54(3) refund position for any accumulated ITC on procurements where the SEZ exemption was not availed. Alert on the RoDTEP anti-double-benefit posture — no SEZ shipment carries a RoDTEP claim, and any operational error where a shipment is inadvertently routed as a DTA export against a RoDTEP scrip must be reversed. The annual Performance Report to the Development Commissioner is the periodic control checkpoint.
SEZ unit master with Letter of Approval reference, Board of Approval registration, Development Commissioner jurisdiction (Kandla SEZ for Dahej, MEPZ for Chennai, Cochin SEZ for Kerala among others), five-year block start date, block end date, and NFE gate posture. Export register with Softex form reference, shipping bill number, FOB value, eBRC receipt date, invoice currency, INR conversion rate, and Authorised Dealer bank identifier. Import register with SEZ Bill of Entry number, CIF value, HSN, tariff heading, and Section 26 exemption avail flag. Foreign-exchange outgoings register with LRS reference, remittance category (royalty, know-how, dividend, ECB interest, other), amount, and Authorised Dealer confirmation. Year-wise NFE workbook computing A minus B per financial year and cumulative Y1 through Y5. DTA sale ledger with Rule 46 duty computation per transfer, Bill of Entry reference, and DTA buyer GSTIN. Section 54(3) refund workbook for any accumulated ITC positions on the domestic-procurement leg. Annual Performance Report generator per the SEZ Rules 2006 format. Rolling alert on the Y5 outer date and on any cumulative NFE trajectory that projects negative at Y5. RoDTEP scrip register cross-checked against SEZ shipment book to catch any inadvertent double-benefit claim.
A quarterly and year-end SEZ block reconciliation pack per unit per Letter of Approval: year-wise A minus B NFE computation with the FOB export leg reconciled to Softex plus eBRC receipts and the CIF import leg reconciled to SEZ Bills of Entry plus LRS-routed foreign-exchange outgoings, cumulative NFE Y1 through Y5 rolled up against the Rule 30 positive gate with a trajectory projection to Y5, DTA sale ledger per Rule 46 with per-transfer customs-duty computation and NFE-outgoings-side treatment, Section 54(3) refund position for any accumulated ITC on the domestic-procurement leg, the annual Performance Report draft in the SEZ Rules 2006 format ready for Development Commissioner submission, and a RoDTEP anti-double-benefit exception report confirming zero SEZ shipments carry an inadvertent RoDTEP scrip claim. The Y5 outer-date alert and the cumulative NFE trajectory projection are the two standing controls that turn Rule 30 from a Y5 surprise into a continuous compliance posture.
A Tier-1 Indian specialty fluoro-intermediate producer operating a manufacturing block within the Dahej Special Economic Zone in Gujarat closes the third quarter of the FY 2024-25 financial year — the mid-point of its five-year Rule 30 block that runs from FY 2022-23 through FY 2026-27. The block’s cumulative Net Foreign Exchange position at the end of Y3 is approximately Rs 510 crore positive, on track for a comfortable Rs 900-plus crore cumulative NFE by Y5. The finance controller’s compliance calendar is nonetheless full: the annual Performance Report to the Development Commissioner at Kandla SEZ jurisdiction is due, a Q3 DTA sale of specialty fluoro-intermediate at Rs 42 crore requires the Rule 46 customs-duty computation to be booked at the SEZ Customs office, and the annual reconciliation between Softex-plus-eBRC export receipts and Rule 30 Y3 numerator must be closed. The reconciliation discipline that turns this operating pattern into a defensible five-year NFE block outcome — with the mandatory positive cumulative gate at Y5, the Rule 46 DTA sale mechanic layered in, the anti-double-benefit RoDTEP posture confirmed, and the Section 54(3) refund route on any accumulated ITC surfaced — is the subject of this SEZ NFE reconciliation specialty chemical block 5 year walkthrough.
The reconciliation in one paragraph
A Special Economic Zone unit producing specialty chemistry within a notified SEZ operates on Section 26 of the Special Economic Zones Act 2005 which grants a wholesale exemption from customs duty on goods imported into the unit for authorised operations, zero-rates supplies from the Domestic Tariff Area to the unit under Section 16 of the IGST Act 2017, and treats the export leg as outside the DTA GST net. Rule 30 of the SEZ Rules 2006 imposes the counter-balancing performance gate — Net Foreign Exchange must remain positive on a five-year cumulative basis measured from the commencement of production, computed as A minus B where A is the FOB value of exports plus specified deemed-export receipts and B is the CIF value of imported inputs and capital goods plus foreign-exchange outgoings on royalty, know-how, dividend, interest on external commercial borrowings and other items. Rule 46 of the SEZ Rules 2006 governs the DTA sale mechanic — customs duty attaches as if the goods were imported into the DTA (Basic Customs Duty plus Social Welfare Surcharge plus IGST plus any compensation cess), the Bill of Entry is filed by the DTA buyer, and the DTA sale value is treated as an outgoing on the B side of the NFE workbook rather than as an export contribution to A. RoDTEP is not applicable to SEZ shipments per the CBIC anti-double-benefit clarification because the SEZ regime already provides equivalent duty-neutralisation. Section 54(3) refund via the zero-rated-supply proviso 1(i) remains available for any accumulated ITC on domestic procurements where the SEZ exemption was not availed. The reconciliation surface is a year-on-year cumulative NFE workbook, a Rule 46 DTA sale duty ledger, and a rolling Y5 outer-date and trajectory alert.
What the scenario looks like in India — a Dahej SEZ specialty fluoro-intermediate block
The Indian Special Economic Zone map for specialty chemistry is anchored in a handful of notified zones located within or adjacent to the primary chemistry corridors. The Dahej Special Economic Zone in Gujarat, sitting within the Petroleum Chemicals and Petrochemical Investment Region (PCPIR) developed by the Gujarat Industrial Development Corporation, hosts the densest concentration of specialty chemistry SEZ blocks — fluorochemistry, phenol-and-acetone derivatives, agrochem intermediates, and downstream petrochemical value chains. The MEPZ SEZ near Chennai, the SEEPZ SEZ at Andheri Mumbai (with a specialty-materials orientation), the Cochin SEZ in Kerala (with a chemicals-and-pharma bias), and the Vishakhapatnam SEZ on the Andhra Pradesh coast complete the primary geography for chemistry-relevant zones. The Development Commissioner jurisdictions differ — Kandla SEZ Development Commissioner for Dahej, MEPZ Development Commissioner for the Chennai zone, Cochin SEZ Development Commissioner for Kerala, and Vishakhapatnam SEZ Development Commissioner for the AP zone.
Illustrative Tier-1 Indian specialty chemistry producers running SEZ blocks or SEZ-relevant manufacturing capacity include Navin Fluorine International (fluorochemistry with a strong presence in the Dahej cluster and a specialty fluoro-intermediate portfolio), GFL (Gujarat Fluorochemicals, fluoropolymers and EV battery electrolyte chemistries at Dahej), SRF Ltd (fluorochemistry, refrigerants and specialty polymer films with multi-site presence), Aarti Industries (benzene intermediates and complex-molecule agrochem intermediates with Dahej-cluster capacity), and Deepak Nitrite (phenol-acetone with the Deepak Phenolics complex at Dahej). Tier-2 chemistry producers with SEZ or SEZ-adjacent footprints include Anupam Rasayan and Neogen Chemicals. For the reconciliation this article walks through, the reference persona is a Tier-1 specialty fluoro-intermediate producer operating a manufacturing block within the Dahej SEZ, with a five-year Rule 30 block that runs from FY 2022-23 through FY 2026-27, an illustrative Y1 FOB export book of Rs 380 crore against Y1 CIF imports of Rs 220 crore producing Y1 NFE of Rs 160 crore positive, and a projected cumulative Y5 NFE outcome comfortably above Rs 900 crore positive.
The regulatory overlay — Section 26 SEZ Act 2005, Rule 30 and Rule 46 SEZ Rules 2006, and the CBIC anti-double-benefit position
Four regulatory anchors govern the SEZ specialty chemistry block. Section 26 of the Special Economic Zones Act 2005 grants the SEZ unit exemption from customs duty on goods imported into the unit for authorised operations, exemption from any Central excise duty on procurement from the Domestic Tariff Area, and zero-rated treatment for GST purposes on supplies from the DTA to the unit under Section 16 of the IGST Act 2017. Corresponding exemptions apply to services and to Central sales tax on inter-state procurement. The exemptions are conditional on the unit maintaining the Letter of Approval issued by the Board of Approval, complying with the annual Performance Report to the Development Commissioner, and clearing the five-year NFE requirement under Rule 30.
Rule 30 of the SEZ Rules 2006 is the operative performance measurement. NFE equals A minus B, where A is the FOB value of exports by the unit during the five-year block including foreign exchange received on account of specified deemed exports, and B is the sum of the CIF value of all imported inputs including capital goods used by the unit during the five-year block plus the value of all payments made in foreign exchange on account of royalty, know-how fees, dividend, interest on external commercial borrowings and other outgoings. The five-year cumulative basis is deliberate — a front-loaded capital-goods import cycle in Y1 and Y2 with a slower ramp on the export leg typically produces negative annual NFE in the early years and recovers to a healthy cumulative positive by Y5. If cumulative NFE at the end of the block is negative the Development Commissioner may initiate action for penalty under the Foreign Trade (Development and Regulation) Act 1992, and the unit faces denial of the exemptions and drawbacks availed over the block period.
Rule 46 of the SEZ Rules 2006 governs the DTA sale mechanic. Where a unit sells goods produced in the SEZ into the Domestic Tariff Area, such supply attracts customs duty as if the goods were imported into the DTA — Basic Customs Duty plus Social Welfare Surcharge at ten percent of BCD plus Integrated GST under Section 3(7) of the Customs Tariff Act 1975 plus any compensation cess applicable to the specific HSN. The Bill of Entry is filed by the DTA buyer at the SEZ Customs office and the duty burden falls on the DTA recipient. For the SEZ unit’s own NFE workbook, DTA sale value is not counted in A as an export contribution; it is treated as an outgoing in B, mechanically reducing the numerator of the NFE ratio. A SEZ unit with a substantial and growing DTA sale book must monitor the NFE trajectory carefully because the DTA leg contributes zero to A while the imported inputs consumed to produce it sit on the B side.
The CBIC anti-double-benefit clarification confirms that the Remission of Duties and Taxes on Exported Products (RoDTEP) scheme notified under the Foreign Trade Policy 2023 is not applicable to exports from a SEZ unit. RoDTEP remits embedded central, state and local duties and taxes that are not otherwise refunded through the GST refund mechanism. The SEZ regime already provides equivalent duty-neutralisation through Section 26 exemptions on inputs and zero-rated treatment of the export leg — there are no residual embedded taxes on a SEZ export shipment for RoDTEP to remit. The same anti-double-benefit position governs the Duty Drawback stacking rule under CBIC Notification 25/2021-Customs, unpacked in the Wave 2 sibling on duty drawback brand rate and RoDTEP stacking for chemical exporters. Section 54(3) of the CGST Act 2017 read with the first proviso clause (i) on zero-rated supplies remains available to the SEZ unit for any accumulated ITC on domestic procurements where the Section 26 SEZ exemption was not availed at the point of procurement.
A worked example — an illustrative Dahej SEZ block from FY 2022-23 to FY 2026-27
Illustrative — the following figures represent the operating pattern of a Tier-1 Indian specialty fluoro-intermediate producer running a Dahej SEZ block over a five-year Rule 30 window. Public disclosures by listed Indian specialty chemistry majors do not reveal per-block per-year NFE quantum in the granularity below; cross-verify against your own SEZ unit’s Softex-plus-eBRC records and SEZ Bill of Entry register before action.
The producer’s five-year block runs from FY 2022-23 through FY 2026-27 with the following year-wise NFE profile in Rs crore:
| Block year | FOB exports (A) | CIF imports plus outgoings (B) | Annual NFE | Cumulative NFE |
|---|---|---|---|---|
| Y1 (FY 2022-23) | 380 | 220 | 160 | 160 |
| Y2 (FY 2023-24) | 450 | 280 | 170 | 330 |
| Y3 (FY 2024-25) | 520 | 340 | 180 | 510 |
| Y4 (FY 2025-26) | 580 | 380 | 200 | 710 |
| Y5 (FY 2026-27) | 620 | 410 | 210 | 920 |
Cumulative NFE at the end of Y5 = Rs 920 crore positive — passes the Rule 30 gate comfortably. The trajectory is a healthy ramp — Y1 NFE of Rs 160 crore positive despite a capital-goods import cycle contributing to the CIF side (a portion of the Rs 220 crore Y1 B leg is capital-goods import for plant commissioning), Y2 through Y5 building on a widening export book as the unit reaches steady-state production. The five-year cumulative outcome is Rs 920 crore positive and well within the compliance envelope. A stress-case scenario where Y4 and Y5 exports slip by twenty percent while imports hold flat would produce cumulative NFE of approximately Rs 680 crore positive at Y5 — still positive and Rule 30 compliant, but with margin narrowing. A more severe scenario where the DTA sale book grows aggressively and the export leg is displaced could push cumulative NFE toward or below zero, triggering the Y5 gate risk.
Layered on top of the Rule 30 workbook is the Rule 46 DTA sale mechanic. If the Y3 DTA sale of specialty fluoro-intermediate at Rs 42 crore attracts BCD at seven and a half percent (Rs 3.15 crore), SWS at ten percent of BCD (Rs 0.315 crore), and IGST at eighteen percent on the assessable value plus BCD plus SWS (approximately Rs 8.19 crore), the total customs duty layer on the DTA transfer is approximately Rs 11.66 crore, filed via Bill of Entry at the SEZ Customs office with the DTA buyer as importer of record. The Rs 42 crore DTA sale value is treated as an outgoing in B for the Y3 NFE workbook rather than as an addition to A, so the Rs 520 crore FOB export figure for Y3 excludes the Rs 42 crore DTA leg — the DTA transfer neither adds to A nor to the CIF import side of B; it slots into the “other outgoings” line as a domestic supply that is not contributing foreign exchange.
Common reconciliation breakages
Five breakages recur across Indian SEZ specialty chemistry units running the five-year Rule 30 block and the Rule 46 DTA sale mechanic side by side.
-
Softex-plus-eBRC gap on the A side. The FOB export figure in A is validated only when the corresponding eBRC receipt is confirmed by the Authorised Dealer bank against the Softex form filed at the shipping bill stage. Where a shipment goes out under Softex but the eBRC is delayed — because of buyer payment slippage, banking-channel routing, or an intermediary AD bank hand-off — the FOB value cannot count in A for the year until the eBRC clears. Units that count all Softex shipments in A regardless of eBRC status over-state cumulative NFE and face a reversal at the annual Performance Report review by the Development Commissioner. Reconciliation discipline: the export register keys FOB value to Softex reference AND to eBRC receipt date, and only eBRC-confirmed receipts flow into the Rule 30 A leg.
-
Foreign-exchange outgoings on the B side under-captured. Rule 30(1)(b) sweeps in not only CIF imports but also foreign-exchange outgoings on royalty, know-how fees, dividend, interest on external commercial borrowings, and other items. A specialty fluoro-intermediate producer paying quarterly royalty to an overseas technology licensor and annual dividend to a foreign shareholder often books these outgoings in a corporate treasury ledger separate from the SEZ unit’s operational books. Where the outgoings ledger is not consolidated into the Rule 30 B leg the NFE figure is over-stated and the cumulative gate looks healthier than it is. Reconciliation discipline: a single LRS-routed foreign-exchange outgoings register per SEZ unit, keyed to the Rule 30(1)(b) categories, consolidates into the annual B computation.
-
DTA sale value inadvertently counted in A as export. Rule 46 DTA sale is not an export for Rule 30 purposes. Where an operations team classifies a DTA transfer as a domestic sale in the general ledger and does not surface it separately for the SEZ NFE workbook, the NFE reconciliation may inadvertently either omit the outgoing entirely from B (under-stating B) or count it as an export contribution to A (over-stating A). Either error inflates cumulative NFE. Reconciliation discipline: the DTA sale ledger is a distinct control account with per-transfer Rule 46 duty computation and per-transfer NFE treatment (added to B under “other outgoings”), reviewed monthly.
-
RoDTEP scrip inadvertently claimed on a SEZ shipment. The anti-double-benefit rule bars a RoDTEP claim on SEZ shipments. Where the DGFT scrip issuance system inadvertently generates a RoDTEP scrip against a SEZ shipping bill — a rare but non-zero operational risk especially where a unit transitioned from DTA to SEZ status mid-cycle — the double-benefit exposure must be identified and the scrip surrendered before it is monetised. Reconciliation discipline: the RoDTEP scrip register is cross-checked against the SEZ shipment book monthly, with any inadvertent overlap flagged for surrender. The reconciliation failure mode analysis design pillar documents the control-design pattern for this class of cross-scheme validation.
-
Cumulative Y5 trajectory not monitored in real time. The Rule 30 gate applies at Y5 as a binary positive-or-negative test. A unit that discovers negative cumulative NFE at the Y5 close has no remedy — the block period has expired and the enforcement consequence attaches. Reconciliation discipline: the year-on-year cumulative NFE workbook projects a Y5 outcome from Y1 onward, and a shortfall projection triggers management action (accelerating the export ramp, deferring a proposed DTA sale expansion, restructuring capital-goods import timing to spread the CIF load beyond the current block). The reconciliation playbook for monthly close operations pillar documents the trajectory-alert cadence that turns Rule 30 from a Y5 surprise into a continuous compliance posture.
How a reconciliation platform handles this
A purpose-built chemicals reconciliation platform ingests the SEZ unit’s Letter of Approval master data, the year-wise Softex-plus-eBRC export receipt register, the year-wise SEZ Bill of Entry import register, the LRS-routed foreign-exchange outgoings ledger, and the DTA sale ledger with Rule 46 duty computations — and produces a year-on-year cumulative NFE workbook per Letter of Approval that reconciles A minus B per year and rolls up cumulative Y1 through Y5 against the Rule 30 positive gate with a trajectory projection to Y5. The platform holds the Rule 46 DTA sale duty ledger with per-transfer BCD-plus-SWS-plus-IGST-plus-cess computation and per-transfer NFE-outgoings-side treatment, generates the annual Performance Report draft in the SEZ Rules 2006 format for Development Commissioner submission, and runs a monthly RoDTEP anti-double-benefit exception report cross-checking the SEZ shipment book against any inadvertent scrip issuance. Match-rate improvement of 51 to 88 percent on the Softex-to-eBRC leg and the SEZ Bill of Entry-to-inventory leg, combined with an ISO 27001:2022 posture and DPDP Act 2023 aligned data handling, is what makes the platform an infrastructure investment for a Tier-1 SEZ specialty chemistry unit — rather than a spreadsheet substitute that leaves the Y5 cumulative gate as a manual annual reconciliation and the Rule 46 DTA sale mechanic as an ad-hoc calculation on each transfer. The Wave 2 sibling walkthroughs on EOU 100 percent export chemical reconciliation and DTA sale ceiling and Advance Authorisation SION input-output norm chemicals reconciliation map the equivalent reconciliation surface for the parallel export-oriented regimes, and the Wave 1 Rule 89(5) specialty chemicals walkthrough documents the Section 54(3) refund mechanic on the domestic-procurement side that remains available to the SEZ unit for any accumulated ITC where the SEZ exemption was not availed. The chemicals cluster hub consolidates the full body of chemistry-sector reconciliation coverage.
- ▸ Rule 30, Special Economic Zones Rules 2006 — Net Foreign Exchange earnings. Every unit shall achieve positive Net Foreign Exchange to be calculated cumulatively for a period of five years from the commencement of production according to the formula NFE = A minus B, where A is the FOB value of exports by the unit during the five-year block including foreign exchange received on account of specified deemed exports, and B is the sum of the CIF value of all imported inputs including capital goods used by the unit during the five-year block plus the value of all payments made in foreign exchange on account of royalty, know-how fees, dividend, interest on external commercial borrowings and other outgoings. If the unit fails to achieve positive NFE cumulatively over the five-year block the Development Commissioner may initiate action for penalty under the Foreign Trade (Development and Regulation) Act 1992 and denial of exemptions and drawbacks availed.
- ▸ Section 26, Special Economic Zones Act 2005 read with SEZ Rules 2006 — Exemptions from duties, taxes and cesses. A unit in a SEZ is entitled to exemption from customs duty on goods imported into the unit for authorised operations, exemption from any Central excise duty on procurement from the Domestic Tariff Area, and to treat all supplies to the unit from the DTA as zero-rated for GST purposes under the Integrated Goods and Services Tax Act 2017. Corresponding exemptions apply to services and to Central sales tax on inter-state procurement. The exemptions are conditional on the unit maintaining the Letter of Approval issued by the Board of Approval and complying with the annual Performance Report and the five-year NFE requirement.
- ▸ Rule 46 and Rule 47, Special Economic Zones Rules 2006 — Domestic Tariff Area sale from a SEZ unit. Where a unit sells goods produced in the SEZ into the Domestic Tariff Area, such supply shall attract customs duty as if the goods were imported into the DTA — Basic Customs Duty plus Social Welfare Surcharge plus Integrated Goods and Services Tax under Section 3(7) of the Customs Tariff Act 1975 plus any applicable compensation cess. The Bill of Entry is filed by the DTA buyer at the SEZ Customs office and the duty burden falls on the DTA recipient. For the SEZ unit's own NFE workbook, DTA sale value is counted in B (outgoings side, treated as a domestic supply for NFE purposes and not as an export), reducing the numerator of the NFE ratio.
- ▸ Section 16, Integrated Goods and Services Tax Act 2017 — Zero-rated supply. Supply of goods or services or both to a Special Economic Zone developer or a Special Economic Zone unit is a zero-rated supply, alongside export of goods or services. Section 16(3) provides two refund routes: refund of the unutilised input tax credit under Rule 89 of the CGST Rules 2017 without payment of tax under Letter of Undertaking, or payment of integrated tax on the supply and refund of the tax so paid under Rule 96. The Section 54(3) refund of unutilised ITC on zero-rated supplies is the parallel refund lever to the direct SEZ Section 26 duty exemption on inward imports — the SEZ unit itself operates on duty-free import plus zero-rated export by design; the Section 54(3) route is more directly relevant to the DTA supplier to the SEZ unit.
- ▸ CBIC clarification on RoDTEP applicability to SEZ shipments — The Remission of Duties and Taxes on Exported Products (RoDTEP) scheme notified under the Foreign Trade Policy 2023 remits embedded central, state and local duties and taxes that are not otherwise refunded through the GST refund mechanism. Exports from a Special Economic Zone unit are not eligible for RoDTEP because the SEZ regime already provides equivalent duty-neutralisation through Section 26 exemptions on inputs and zero-rated treatment of the export leg. The anti-double-benefit position is that a shipment cannot simultaneously claim SEZ exemptions and a RoDTEP scrip on the same export invoice. The same principle governs the Advance Authorisation and EOU regimes — the scheme electing benefit-neutralisation determines which incentive stack applies to a given shipment.
