Shipping Bill Amendment After LEO: Section 149, Process and Documents

Can a shipping bill be amended after export? Yes, under Section 149 of the Customs Act, but only with documents that existed when the goods were exported. Who approves it, the documents to file, converting a free shipping bill to drawback, and what to fix on your side afterwards.

Yes, a shipping bill can be amended after the goods are exported, but only on the basis of documents that already existed when they were exported. That's the rule in Section 149 of the Customs Act, 1962. Before the Let Export Order (LEO), corrections are routine. After LEO, the request goes to the Deputy or Assistant Commissioner in charge of exports at the port, with supporting documents, and approval is at their discretion.

This post covers the practical side: what can be changed, who approves it, what to file, and the follow-up on your own documents. For where amendments fit in the shipping bill's life, see what happens after you file a shipping bill.

What Section 149 says, in plain terms

  • The customs officer may allow any document presented to customs, including a shipping bill, to be amended.
  • Once the goods have been exported, an amendment is allowed only on the basis of documentary evidence that existed at the time of export.
  • So you can correct a shipping bill to match the real invoice, packing list or contract. You can't use a document created afterwards to change what was declared.

In practice, if your commercial invoice said 420 cartons and the shipping bill says 240, you can fix it. If the buyer renegotiates the price a month after sailing, the new price doesn't go back onto the shipping bill. That gets handled through a credit or debit note and your bank.

Before LEO vs after LEO

StageHow it's handledWho approves
Before LEOYour CHA requests the correction at the customs station; it's made in the EDI system before assessment or examination is completeThe proper officer at the port
After LEO, goods not yet sailedWritten request with supporting documents. If the shipment is cancelled or shut out, it's a different processDeputy or Assistant Commissioner (Exports)
After exportWritten request under Section 149 with documents that existed at the time of exportDeputy or Assistant Commissioner (Exports); conversion requests go to the Commissioner
EGM also wrongThe shipping line or its agent files an EGM amendment separatelyCustoms, on the carrier's request

Amendments exporters ask for most

  • Invoice number or date that doesn't match the GST invoice. This blocks the IGST refund, because the refund is matched between the shipping bill and your GST return.
  • Quantity, package count or weight typed wrong compared with the packing list.
  • FOB value or currency that doesn't match the commercial invoice.
  • HS code entered wrongly. Changing it can change the drawback or RoDTEP rate, so expect closer scrutiny.
  • Consignee name or address errors.
  • Converting the shipping bill type, for example free to drawback, or one export scheme to another.

Converting a free shipping bill to drawback

If the CHA filed a free shipping bill when you were entitled to duty drawback, you lose the drawback unless the shipping bill is converted. CBIC allows conversion at the Commissioner's discretion under its conversion circular (Circular 36/2010-Customs, as amended). Conditions include a time limit counted from the LEO date (three months under that circular), and the goods and documents on record must support the claim. Ask your CHA to check the current circular before you file, because these conditions get revised. To avoid needing it at all, see types of shipping bill and RoDTEP vs duty drawback.

Documents to attach to an amendment request

  1. A request letter to the Deputy or Assistant Commissioner (Exports): shipping bill number and date, what's wrong, the correct details and why the error happened
  2. A copy of the shipping bill and the LEO
  3. The commercial invoice and packing list as issued at the time of export
  4. The bill of lading or air waybill
  5. Proof of the correct details from before export: purchase order, sales contract, LC, or the GST invoice
  6. For a value or currency change, any bank documents that support it
  7. A CHA authorisation, if the CHA files on your behalf

Every supporting document has to be dated on or before the export. That's the Section 149 test.

Is there a time limit?

Section 149 doesn't set a fixed deadline for ordinary amendments, but the longer you wait, the harder it is to show that the evidence existed at export, and refund or incentive deadlines keep running. Conversion requests do have a time limit under the CBIC circular. File as soon as you spot the error.

After the amendment: fix your own records

An amended shipping bill doesn't change anything else on its own. Check that these match it:

  • Your commercial invoice and packing list. If they were right and the shipping bill was wrong, nothing to do. If not, issue corrected copies.
  • Your GST return (GSTR-1 export details), so the IGST refund or LUT export matches.
  • The EGM, if the shipping line's manifest carries the same error.
  • Your bank's export record, so the eBRC links to the right shipping bill and value.

Frequently Asked Questions

Can a shipping bill be amended after export?

Yes, under Section 149 of the Customs Act, but only on the basis of documents that existed at the time the goods were exported, and with approval from the Deputy or Assistant Commissioner in charge of exports.

Who approves a shipping bill amendment?

Before LEO, the proper officer at the customs station. After LEO or export, the Deputy or Assistant Commissioner (Exports). Conversions between shipping bill types or schemes need the Commissioner.

Can I convert a free shipping bill into a drawback shipping bill?

Often, yes, at the Commissioner's discretion under CBIC's conversion circular, within its time limit from the LEO date. Check the current conditions with your CHA.

Does amending the shipping bill change the LEO date?

No. The LEO date is the date of export and stays the same. The amendment only corrects the declared details.

Can I change the price on the shipping bill after the buyer renegotiates?

Usually not, because the new price didn't exist at the time of export. Record the change with a credit or debit note and tell your bank. See when to issue a credit note vs a debit note.


Most amendments start as a shipping bill filed from a draft invoice or an old packing list. Bilexor keeps the invoice and packing list on one shipment record, so what your CHA files matches what you send the buyer and the bank. Bilexor doesn't file shipping bills or amendments. Informational only, not legal or customs advice: confirm the current procedure with your CHA and the customs station.

Informational only — not legal, banking, tax, or customs advice. Always verify document and LC requirements with your bank, CHA / customs broker, and buyer before presentation.
