Comprehensive Technical GuidanceTextbook & Training SOP

1. Originality Standards under UCP 600 Article 17

Under UCP 600 Article 17:

  • At least one original of each document stipulated in the credit must be presented.
  • A document is treated as an original if it bears an apparently original signature, mark, stamp, or label of the issuer of the document.
  • Unless a document indicates that it is not an original (e.g., marked "Copy"), a bank will accept a document as an original if it appears to have been produced on the issuer's original stationery or appears to be printed or typed.

2. Chamber Attestation & Legalization SOP

For shipments to the Middle East (Saudi Arabia, UAE, Qatar, Egypt) and South America:

  1. Invoice Drafting: Print the required declaration clause on the invoice body:

    "We hereby guarantee that this invoice is true and correct, that the goods are of pure Bangladesh origin, and that the prices stated herein represent genuine market value."

  2. Chamber Submission: Submit invoice copies to the Dhaka Chamber of Commerce & Industry (DCCI) or Metropolitan Chamber of Commerce & Industry (MCCI).
  3. Embassy Consularization (if required): If the L/C mandates embassy legalization, the chamber-attested invoice is submitted to the Ministry of Foreign Affairs (MOFA) and the destination country's embassy in Dhaka.

3. Signature & Specimen Card Protocols

Always ensure the title beneath the signature matches the authorized role (e.g., "Authorized Commercial Signatory" or "Director Operations").

Practical Commercial Flow

Executing Chamber Attestation for a $95,000 Export to Saudi Arabia

Master L/C for a Saudi Arabian buyer mandates: "Commercial Invoices in 3 originals attested by a recognized Chamber of Commerce." Commercial Executive prints 3 original invoices, signs in blue ink, and submits to the Dhaka Chamber of Commerce & Industry (DCCI). DCCI validates the factory membership, applies the embossed official seal and verification stamp, and returns the attested invoices within 24 hours.

Factory Real-Life Scenario

Scenario: A commercial bank rejected an export document presentation because the Commercial Invoice was signed by a Junior Merchandiser whose signature was not on the bank's authorized signatory specimen card.

Solution: Commercial Manager cancelled the invoice and had it re-signed by the factory's registered Director whose signature was on file with the bank.

Impact: Regularized the file and secured instant negotiation.

Commercial Officer Best Practice

Always register at least 2 or 3 senior commercial executives on your commercial bank's Authorized Signatory Card to prevent submission delays when directors are traveling.

Top Beginner Mistakes to Avoid

  • Signing export invoices with black ink, causing bank examiners to question whether the document is an original or photocopy.
  • Failing to obtain chamber attestation prior to the L/C document presentation deadline.
