Overview
What is an Export Invoice?
An export invoice is a tax invoice issued for the export of goods or services. Under Section 16 of the IGST Act, exports are zero-rated — meaning the supply is taxable but the effective tax rate is zero, and the supplier can either pay IGST and claim a refund, or supply under a Letter of Undertaking (LUT) without paying any tax.
It must follow the standard tax-invoice format with a few additions: place of supply is "Other Territory" (state code 96), HSN must be 8-digit, and the document must show the export type (with payment / under LUT), the shipping bill / port code (for goods), and the foreign currency along with the INR equivalent.
Exports are reported in Table 6A of GSTR-1. For IGST-paid exports, the GSTR-1 data flows to ICEGATE for refund processing — so the shipping bill number and port code must match exactly.

FAQ
Frequently asked questions
Everything you need to know about export invoice generation.
What is the difference between LUT and IGST-paid export?+
Under LUT (filed annually), you export without charging IGST — simpler cash flow but no refund. With IGST payment, you charge IGST, pay it to the government, then claim a refund — slower but works without an LUT.
Do I need to charge GST on an export invoice?+
Only if you have not filed an LUT. With LUT, GST = 0 on the invoice. Without LUT, you charge IGST at the applicable rate and claim refund later.
What HSN length is required for exports?+
8-digit HSN is mandatory for export of goods, regardless of turnover. For services, 6-digit SAC is sufficient.
Is a GSTIN required for the foreign buyer?+
No. Foreign buyers do not have an Indian GSTIN. Leave the field blank — the place of supply (96 / Other Territory) handles the export treatment.
Which currency should the invoice be in?+
The invoice can be in any foreign currency. You must also show the INR equivalent at the CBIC rate notified for that calendar month (for goods) or at the RBI reference rate on the invoice date (for services).
Where do exports appear in GSTR-1?+
Table 6A. For IGST-paid exports, the data is shared with ICEGATE — match the shipping bill number, date, and port code exactly to get your IGST refund processed without queries.
