KORUS FTA Blanket Certificate of Origin: Guidance on Validity Periods and Quantity Requirements Released

As a professional customs consultant, I would like to provide a detailed explanation regarding the issuance of a Blanket Certificate of Origin (CO) for goods exported repeatedly to the United States. The blanket CO system is designed to enhance efficiency in applying FTA preferential rates by eliminating the administrative burden of issuing a separate certificate for every shipment of the same product. This is a critical provision under the Korea-U.S. Free Trade Agreement (KORUS FTA).

1. Specifying the Blanket Period on the Certificate of Origin

Under the KORUS FTA, the validity period of a blanket certificate of origin may be set for a period not exceeding 12 months from the date the certificate is completed. According to Article 6.15 (Certificate of Origin) of the KORUS FTA, exporters or producers are permitted to establish a validity period of up to one year when providing the certificate to the importer.

Example: If the certificate is completed on March 8, 2024, the validity period should be specified as "From 2024/03/08 To 2025/03/07." It is important to set the end date as the day before the 12-month anniversary of the start date to ensure the total duration does not exceed 12 months. As long as the identical goods continue to meet the rules of origin during this specified period, the blanket CO can be used repeatedly.

Setting this blanket period is a practical convenience measure that reduces the administrative workload for companies and facilitates the efficient application of FTA preferential duties in recurring trade relationships.

2. Requirement for Specifying Export Quantities

Regarding your question on whether quantities must be specified when order volumes vary, the mandatory data elements for a KORUS FTA Certificate of Origin provide a clear answer.

The mandatory data elements for a KORUS FTA Certificate of Origin do not include the quantity of goods. Specifically for blanket certifications, the regulations mandate the validity period rather than the quantity. Therefore, it is perfectly acceptable—and legally compliant—to omit the quantity on the blanket CO.

This regulation aligns with the institutional purpose of the blanket CO. The certificate proves that the specific 'good' itself satisfies the rules of origin; it reflects the nature of repetitive trade where quantities vary per shipment. Even without a specified quantity, all identical goods exported within the validity period are eligible for preferential treatment. In fact, specifying a fixed quantity can lead to unnecessary complications, such as requiring a new certificate if the quantity is exceeded or causing discrepancies during customs clearance. Therefore, unless there is a specific reason to do so, it is generally recommended and standard practice not to list quantities on a blanket CO.

3. Key Considerations for Utilizing Blanket Certificates of Origin

• Consistency in Origin Status: All goods exported during the blanket period must maintain the same product description, HS Code, and origin criteria. If the origin status changes due to modifications in specifications, production processes, or raw materials, the existing blanket CO must be reviewed and a new one issued if necessary.
• Strict Record Keeping: Exporters issuing a blanket CO must maintain all supporting documentation (e.g., production records, raw material purchase invoices, cost statements, Bill of Materials (BOM)) for the period required by the KORUS FTA (typically 5 years from the date of export). This is essential to prepare for post-clearance audits by customs authorities such as the U.S. Customs and Border Protection (CBP).
• Importer Communication: It is vital that the importer understands the purpose and application of the blanket CO to ensure smooth duty benefits. Communicating with the importer before issuance and providing a copy of the certificate along with explanatory materials can prevent misunderstandings.
• Compliance with Agreement Regulations: Detailed regulations regarding data elements and validity periods can vary across different FTAs. It is always advisable to consult the specific agreement text and guidelines provided by customs authorities (e.g., Korea Customs Service or U.S. CBP).

While the blanket CO is an effective tool for maximizing FTA utility, it requires accurate understanding and systematic management. By following these guidelines, you can successfully leverage the KORUS FTA for your exports.
