Export Invoice › Currency, port and shipping bill
Currency, port code and shipping bill on an export invoice
The export details section of the maker holds the lines that customs, banks and the e-invoice portal look for. Here is what each one means and where to find it.
The fields
| Field | What to type | Example |
|---|---|---|
| Invoice currency | The buyer's currency, as a 3-letter code | USD |
| Exchange rate | Rupees for 1 unit of that currency | 88.50 |
| Country of destination | Where the goods go (printed with its 2-letter code) | United States (US) |
| Port code | 6-character customs code of the port, airport or ICD of loading | INNSA1 |
| Shipping bill No. and date | From the shipping bill your customs broker files. Often known only after the invoice; add it then and save again. | 1234567 · 06/11/2026 |
| LUT reference and date | The ARN of your Letter of Undertaking (only for exports without IGST) | AD0304260001234 |
The value in foreign currency
The maker divides the rupee total by your exchange rate and prints, for example, Invoice value in USD: USD 4,237.29 (at 1 USD = ₹88.50). The rupee figures stay the legal ones for GST. If your buyer agreed a dollar price, work out the rupee rate per unit (dollar price × exchange rate) and type that.
In the e-invoice
For businesses that e-invoice, the export details go into the file's ExpDtls section: shipping bill number (ShipBNo) and date (ShipBDt), port (Port), currency (ForCur), country code (CntCode) and whether you claim a refund (RefClm). The buyer is sent as URP with state and place of supply 96 and PIN 999999, as the schema asks for exports.
Worked example
Invoice total ₹3,75,000 for a buyer in the United States, exchange rate ₹88.50: 375000 ÷ 88.50 = USD 4,237.29. Port INNSA1 (Nhava Sheva), shipping bill filed the next day: open the saved invoice, add the number and date, Save, and print again.
