Exporting Through Tariff Volatility (2026): GST Refunds, LUT, RoDTEP, DGFT Schemes and Cash-Flow Tactics for Indian Exporters
- When a destination market raises tariffs, the Indian exporter cannot change the duty but can stop leaking cash at home: every rupee of GST, customs duty and state levy embedded in exports is refundable or remittable if the paperwork is right.
- Export under LUT without paying IGST and claim refund of unutilised input credit; paying IGST and claiming it back ties up working capital for weeks you no longer have.
- RoDTEP, duty drawback, Advance Authorisation and EPCG together typically recover 1–6% of FOB value — often the whole margin a tariff shock removes.
- Lever 1 — zero-rating under GST, done the cash-efficient way
- Lever 2 — remission schemes that return embedded taxes
- Lever 3 — duty-free inputs and capital goods
- Lever 4 — market and currency diversification
- Lever 5 — protecting the receivable

Since 2025, exporters across sectors — textiles, gems and jewellery, engineering goods, chemicals, seafood, leather — have faced sudden tariff increases in major destination markets, retaliatory announcements, and buyers asking suppliers to "share" the duty. An Indian exporter cannot alter another country's tariff schedule. What it can control is the cost structure at home: whether domestic taxes are fully removed from the export price, how fast refunds arrive, which incentive schemes are actually claimed, and whether the receivable is protected. This guide sets out those levers as they stand under GST and the Foreign Trade Policy in 2026.
Lever 1 — zero-rating under GST, done the cash-efficient way
Exports of goods and services are zero-rated supplies under section 16 of the IGST Act. There are two routes:
| Route | How it works | Cash impact | Best for |
|---|---|---|---|
| Export under LUT (Letter of Undertaking) without payment of IGST | File LUT on the GST portal (valid for the financial year), export without charging IGST, claim refund of unutilised input tax credit under rule 89 | No IGST outflow; refund of accumulated ITC within 60 days of a complete application (provisional 90% within 7 days for low-risk) | Almost every exporter, especially those with high input credit |
| Export with payment of IGST and refund | Charge IGST on the export invoice, pay it through the return, refund processed automatically against the shipping bill once GSTR-1 and GSTR-3B match | IGST paid up-front and returned in 2–6 weeks; blocks working capital | Exporters with surplus cash credit who prefer automatic processing |
Under tariff pressure, the LUT route is almost always right. Make sure GSTR-1 export invoices carry the correct shipping-bill number, port code and date; mismatches are the main cause of refund delays. Services exporters must receive payment in convertible foreign exchange (or INR where permitted by RBI) and have FIRC or BRC evidence.
Lever 2 — remission schemes that return embedded taxes
- RoDTEP (Remission of Duties and Taxes on Exported Products): rebates central, state and local levies not refunded under GST — electricity duty, mandi tax, fuel VAT on transport — at notified rates by HS code, typically 0.3% to 4% of FOB, credited as transferable scrips in the customs ledger. Claim it by declaring intent on the shipping bill; a missed declaration cannot be fixed later.
- Duty drawback: refunds customs duty on imported inputs at All-Industry Rates or brand rates; paid directly to the bank account against the shipping bill.
- RoSCTL for apparel and made-ups, in place of RoDTEP for those chapters.
Lever 3 — duty-free inputs and capital goods
- Advance Authorisation: import inputs duty-free against an export obligation, using Standard Input-Output Norms or a self-declared norm; the obligation must be met within 18 months.
- EPCG: import capital goods at zero customs duty against an export obligation of six times the duty saved over six years. Useful when a tariff shock forces a move to higher-value products requiring new machinery.
- Duty-Free Import Authorisation and SEZ / EOU status for units that export the bulk of output.
Lever 4 — market and currency diversification
India's free-trade agreements — with the UAE (CEPA), Australia (ECTA), the EFTA states, and the UK agreement concluded in 2025 — give preferential or zero tariffs that a shock in one market makes suddenly valuable. Obtaining a Certificate of Origin under the relevant agreement and meeting its rules of origin is the paperwork; the DGFT common digital platform issues them. On currency, invoicing in the buyer's currency with a forward cover, or in INR where the buyer agrees and RBI's rupee-settlement mechanism applies, removes a second source of volatility from an already uncertain order.
Lever 5 — protecting the receivable
Tariff shocks produce buyer defaults and renegotiations. Export credit insurance through ECGC covers commercial and political risk on open-account sales for a premium of a fraction of a percent; it also makes banks more willing to discount export bills. Pre-shipment (packing credit) and post-shipment finance in foreign currency (PCFC) is priced off SOFR plus a spread and is usually cheaper than rupee working capital. Insist on at least a documentary collection, or a letter of credit, with new buyers in volatile markets.
A 30-day action list for an exporter hit by a tariff change
- Confirm the LUT is filed for the year and switch any IGST-paid exports to the LUT route.
- File pending ITC refund claims month by month; reconcile GSTR-2B so that credit is not stuck.
- Check every shipping bill since April for the RoDTEP declaration and drawback claim; recover what was missed where the time limit allows.
- Price the next quotation net of RoDTEP, drawback and the GST refund so the "share the duty" conversation starts from the real margin.
- Apply for Certificates of Origin for FTA markets and brief the buyer's customs broker.
- Take ECGC cover on open-account buyers; move the credit limit to PCFC.
- Re-run the working-capital cycle: longer receivables and slower refunds mean a higher cash-credit need; update the CMA data before the bank's review.
Refund filings, LUT, GSTR-1 shipping-bill reconciliation and the export-invoice rules are handled under the GST Filing and Refunds service; DGFT scheme applications are coordinated with licensed customs brokers.
Common mistakes
- Paying IGST on exports "because the refund is automatic" while borrowing at 11% to fund it.
- No RoDTEP declaration on the shipping bill. The claim is lost for that shipment.
- Shipping-bill details wrong in GSTR-1 — the single biggest cause of stuck refunds.
- Services exported without FIRC or BRC, or paid into a non-convertible account, losing zero-rated status.
- Quoting ex-works to a buyer who then asks for CIF after a tariff change, absorbing freight on top of duty.
- Letting the Advance Authorisation obligation lapse, converting a duty saving into duty plus interest.

Open GST Filing and Refunds →Frequently asked questions
Should I export under LUT or pay IGST and claim a refund?
Under LUT in nearly every case. You export without charging IGST and claim refund of the input credit you accumulated, so no cash goes out. Paying IGST and claiming it back is processed automatically but blocks working capital for two to six weeks per shipment — a cost that matters when buyers are already pressing on price.
What is RoDTEP and how do I claim it?
The Remission of Duties and Taxes on Exported Products scheme rebates central, state and local levies that GST does not refund — electricity duty, fuel VAT, mandi tax — at notified rates by HS code, typically 0.3% to 4% of FOB value, as transferable scrips in your customs ledger. You claim it by declaring the intent on each shipping bill at the time of export; it cannot be claimed afterwards.
How fast do GST export refunds arrive?
For refunds of unutilised ITC under LUT, the law requires sanction within 60 days of a complete application, with 90% provisional refund within seven days for low-risk exporters. In practice, clean applications with GSTR-1 shipping-bill data matching customs are paid in two to four weeks; mismatches add months.
Which free-trade agreements can Indian exporters use in 2026?
Preferential access exists under the India-UAE CEPA, India-Australia ECTA, the India-EFTA agreement, the India-UK agreement concluded in 2025, and older agreements with ASEAN, Japan, Korea and SAARC countries. Each requires a Certificate of Origin under its own rules of origin, issued through the DGFT digital platform.
