Compliance Requirements (2025)
To ensure correct COO documentation, businesses must adhere to U.S. Customs and international trade rules. Accurate COO declarations impact tariff rates, qualification for trade agreements, and compliance checks.
Key Considerations for COO Compliance
- HTS Code Classification: COO directly impacts the Harmonized Tariff Schedule (HTS) code classification, which determines the tariff rate applied to imports.
- Rules of Origin: Under agreements like USMCA, COO must align with specific rules that define how much of a product's value must come from the originating country to qualify for benefits.
- Documentation: Exporters must provide a Certificate of Origin (CO) to confirm the product’s origin for customs clearance, and may require a declaration for products subject to duties or trade restrictions.
