What a shipping bill is
The Shipping Bill is generated through Indian Customs' EDI (Electronic Data Interchange) system and is the core document that proves an export actually happened. It's filed only once all required documents are in order and the goods are genuinely ready to leave India for a destination outside the country.
It has five parts: (1) Shipping Bill Summary, (2) Invoice Detail, (3) Item Details, (4) Export Scheme Details, and (5) Declaration.
Why it matters for GST filing
Three fields from the shipping bill — Port Code, Shipping Bill Number, and Shipping Bill Date — are the core data points you report under GSTR-1 Table 6A, where export sales are declared. If any of these three fields is entered incorrectly and only discovered later, it's corrected through Table 9A in a subsequent GSTR-1, not by editing the original filing.
Critical practical rule: the details in your shipping bill and your GSTR-1 filing must match exactly. A mismatch between the two is one of the most common causes of a delayed export refund — treat consistency between these two documents as a hard requirement, not a minor detail to clean up later.
Key terms that show up on every shipping bill
- Mode: how the shipment travels — sea, air, road, or land.
- Assessment / Examination: whether customs processed and physically examined the shipment. Assessment isn't always mandatory, but both steps commonly happen together in practice — document submission, assessment, and physical examination (checking package count, HSN match, etc.) all happen before goods are cleared to load.
- Jobbing: whether this was a job-work export (goods processed on someone else's behalf under an associated arrangement) versus a straightforward trade shipment (bought the goods, sold them onward, no job-work relationship). This affects eligibility for certain export incentive schemes.
- Duty Drawback: a refund of basic customs duty paid on input goods used in the exported product. If claimed, the applicable rate is either the AIR (All Industry Rate) or a product-specific Brand Rate.
- RODTEP (Remission of Duties and Taxes on Export Products): if opted into, requires specifying the scheme code and the applicable benefit percentage. This is the scheme that replaced the older MEIS (Merchandise Export Incentive Scheme), which is no longer active.
- License-based incentives: DGFT issues specific export-incentive licenses like the EPCG (Export Promotion Capital Goods) scheme or Advance License — relevant if you're importing capital goods or inputs duty-free against an export commitment. Not applicable to every shipment.
- DFRC (Duty Free Replenishment Certificate): lets you import replacement inputs duty-free against proven export performance, calculated as a percentage.
- Re-export: goods that were imported back into India (for example, for warranty repair) and are now being sent out again — a distinct category from a standard fresh export.
- LUT (Letter of Undertaking): filed with the GST department, in which the exporter declares they will ship the goods and realize payment in convertible foreign currency within the stipulated time. Filing an LUT lets you export without paying IGST upfront. The alternative is paying IGST at the time of export (shown as a payment in GSTR-3B and as an export sale in GSTR-1) and then claiming that IGST back as a refund afterward, through the ICEGATE portal. Either route is valid — LUT avoids the upfront cash outflow, while the IGST-paid route requires claiming a refund after the fact.
- FOB (Free on Board) value: the exporter's cost responsibility ends at the origin port — no freight, insurance, discount, commission, or prior-transaction deduction included beyond that point. Everything past the origin port (ocean/land freight onward, insurance) is the buyer's cost under FOB terms. If freight and insurance are added into the exporter's price instead, that's a CIF quote, not FOB.
- MAWB / HAWB (Master Airway Bill / House Airway Bill): only relevant for air shipments — left blank for sea, road, or land shipments.
- BRC (Bank Realisation Certificate): the document confirming that payment for the export has actually been received; its issue date is tracked as part of the shipment record.
- LEO (Let Export Order): the official customs clearance for the goods to be loaded onto the vessel/aircraft — goods aren't loaded until this is issued, and its number and date are part of the shipment's timeline record.
Structure recap
- Part A: shipment status — mode, assessment, examination, jobbing, duty drawback, RODTEP, license, DFRC, re-export, and LUT/IGST-payment status.
- Part B: exporter and importer details.
- Part C: value summary (FOB or CIF).
- Section E: manifest detail (MAWB/HAWB, air shipments only).
- Part D: any incentive/scheme claims made, or IGST payment details if no scheme was claimed.
- Part F: invoice summary — invoice number, amount, and currency (export invoices can legitimately be issued in a foreign currency).
- Equipment/challan details: container and serial numbers, dates, if applicable.
- Annexure: whether the shipment was warehouse-sealed, nature of cargo (loose packages vs. containerized), number of packages, and marking/numbering matching the invoice.
- Part J: the full event timeline — when documents were submitted, when assessment and examination happened, and the LEO number/date.
- Declaration: filed on the exporter's behalf by the Customs House Agent (CHA)/customs broker, referencing their Customs Broker (CB) license code.
Bottom line
The shipping bill isn't just a customs formality — its data feeds directly into your GST export filings and refund eligibility. Getting the port code, shipping bill number, date, and value terms (FOB vs. CIF) right the first time, and keeping them consistent with your GSTR-1, is what keeps refunds moving instead of stuck in a mismatch dispute.
