Bill of Lading Modifications: What Information Cannot Be Changed?

The Bill of Lading (B/L) is one of the most critical documents in international trade and shipping. It serves as a receipt of cargo, a contract of carriage, and a document of title, making it legally binding. Due to its importance, modifications to a Bill of Lading must be handled with extreme care to ensure compliance with shipping laws and avoid legal disputes.

While certain details can be amended, there are key elements that cannot be changed once the B/L has been issued and endorsed. This article explores Bill of Lading modifications, the limitations of changes, and best practices for ensuring accurate documentation.

1. Why Is Modifying a Bill of Lading Important?

A Bill of Lading must contain accurate and verified information about the shipment. However, mistakes, incorrect details, or unforeseen changes may require modifications before the cargo arrives at its destination.

✔ Common Reasons for Modifications:

• Clerical errors (spelling mistakes, wrong address, incorrect cargo weight).
• Changes in consignee or notify party details.
• Updates to Incoterms or freight payment terms.
• Cargo quantity adjustments due to loading discrepancies.

However, not all details can be modified, and certain changes may require issuing a Switch Bill of Lading or surrendering the original B/L.

2. Information That CANNOT Be Changed on a Bill of Lading

Certain information on a Bill of Lading is legally binding and cannot be altered once the document has been issued. Any unauthorized modifications may invalidate the B/L or lead to legal and financial disputes.

2.1 The Shipper’s Name (After Cargo Handover)

• Once the shipper has handed over the cargo to the carrier, their name cannot be changed on the B/L.
• This is because the shipper’s identity is tied to trade contracts, financial transactions, and export customs clearance.

✔ Alternative Solution: If a change in seller information is needed, a Switch Bill of Lading may be issued with approval from all parties involved.

2.2 The Freight Payment Terms (Prepaid vs. Collect)

• The freight payment terms on a Bill of Lading indicate whether the shipping cost is prepaid by the shipper or payable at the destination by the consignee.
• Once the B/L has been issued, the payment method cannot be changed, as it affects financial agreements between parties.

✔ Alternative Solution: Any freight-related changes must be handled through financial settlements between the shipper and consignee rather than modifying the B/L.

2.3 Cargo Description and Quantity (Unless Verified by Carrier)

• The cargo description, weight, and number of units on the B/L must match the actual shipment.
• Once the cargo is loaded, these details cannot be changed arbitrarily to prevent fraud or customs violations.

✔ Exception: If a clerical mistake occurred, a B/L amendment may be requested, but only with carrier approval and supporting documentation.

2.4 Date of Shipment (Sailing Date)

• The date of shipment (onboard date) confirms when the cargo was loaded onto the vessel.
• This date is critical for Letter of Credit (L/C) payments, insurance claims, and customs clearance.
• Once the vessel has sailed, the date cannot be altered.

✔ Exception: If a mistake occurred, an amendment request must be supported by the shipping line with proper justification.

2.5 Vessel Name and Voyage Number

• The vessel name and voyage number identify the ship carrying the cargo.
• These details cannot be changed after departure, as they are linked to customs filings, trade documents, and tracking systems.

✔ Alternative Solution: If cargo is transferred to another vessel due to operational reasons, the carrier must issue an endorsement or correction letter to reflect the change.

2.6 Port of Loading and Port of Discharge

• The port of loading and port of discharge define the agreed shipping route and are part of the contract of carriage.
• These details cannot be modified once the cargo is on board.

✔ Alternative Solution: If a new delivery location is needed, the consignee must request a Change of Destination (COD) from the carrier, which may involve additional charges.

3. Information That CAN Be Changed on a Bill of Lading

While some modifications are restricted, the following details can be amended under specific conditions:

✔ Typographical errors (misspelled consignee name, incorrect address).
✔ Notify party details (updating contact information).
✔ Container numbers (if an error occurred).
✔ Cargo value (for non-negotiable B/Ls only).

All modifications require written approval from the carrier, supporting documentation, and in some cases, consent from banks or trade authorities.

4. Best Practices for Ensuring Accurate Bill of Lading Information

To avoid complications, delays, and legal risks, shipowners and exporters should follow these best practices:

✅ 4.1 Double-Check All Details Before B/L Issuance

• Ensure that the shipper, consignee, cargo description, and freight terms are correct before submitting the draft B/L.

✅ 4.2 Use a B/L Checklist

• Verify essential details like container numbers, port names, and payment terms before finalizing the document.

✅ 4.3 Communicate Changes Early

• If an amendment is required, request it before the B/L is printed or released.

✅ 4.4 Consult With the Carrier on Modifications

• Only request permissible changes, and ensure carrier approval before proceeding with modifications.

✅ 4.5 Consider a Switch B/L for Major Changes

• If a consignee, shipper, or trade route needs to be changed, consider using a Switch Bill of Lading instead of modifying the original.

✔ Proper documentation management prevents disputes, customs issues, and financial risks in global trade.

5. Conclusion

A Bill of Lading is a legally binding document, and certain information cannot be changed after issuance. Key details like the shipper’s name, cargo description, sailing date, and port details must remain unchanged to ensure compliance with trade laws, customs regulations, and financial agreements.

For minor errors, amendments may be possible with carrier approval, while major changes may require issuing a Switch Bill of Lading.

By verifying information before B/L issuance and following best practices, shippers can avoid costly mistakes, legal disputes, and shipment delays in international trade.
