C/O Form B: essential certificate for Vietnam–USA export

Exporting from Vietnam to the USA (United States of America) requires more than just a good product and a willing buyer. It demands precision in documentation, compliance with international trade protocols, and a deep understanding of customs procedures. Among the essential export documents is the Certificate of Origin (C/O), and specifically, Form B, which plays a crucial role in non-preferential trade. In this article, Fastrans, a trusted partner in freight forwarding, shares valuable insights and practical knowledge about C/O Form B based on years of experience supporting exporters.

What is C/O Form B?

A Certificate of Origin Form B is a non-preferential document that certifies a product was manufactured or processed in Vietnam. Unlike preferential C/O like Form A (GSP), Form D (ATIGA), or Form E (ACFTA), which offer tariff reductions under specific trade agreements, Form B is used for countries with no such agreements with Vietnam. For Vietnamese exporters targeting the U.S. market, Form B is the appropriate C/O type.

Though it does not provide tariff preferences, it is still highly important for proving the origin of goods, meeting buyer requirements, and satisfying U.S. customs compliance.

Why is C/O Form B Important for Exporting to the USA?

Even if the U.S. does not provide tariff incentives, C/O Form B helps prevent shipment delays, avoid unnecessary scrutiny, and build trust with American partners.

• Customs Requirements: U.S. Customs and Border Protection (CBP) may request proof of origin during clearance
• Buyer Specifications: Many American retailers and importers require certificate of origin for documentation and audit purposes
• Trade Defense and Anti-fraud: Proper origin certification helps avoid penalties or investigations related to anti-dumping, especially for sensitive goods.
• Professionalism: Submitting Form B enhances your credibility and signals that your business complies with global trade practices.

Applying for a Certificate of Origin (C/O) Form B typically involves a government-issued fee of USD 30 per set, which is standard across most issuing authorities.

While the application cost itself is relatively low, any rejection can result in shipment delays, extra administrative work, and even financial penalties due to the loss of tariff preferences.
