⚠️ GSP Statutory Caveat: Tariff preference codes A, A+, A* refer to the U.S. Generalized System of Preferences. GSP duty-free entry applies when GSP statutory authorization is currently in effect by U.S. Congress.
📜 Certificate of Origin Requirement: Preferential tariff treatment requires a valid Certificate of Origin demonstrating compliance with product-specific Rules of Origin (tariff shift or Regional Value Content). Eligibility is not automatic — verify origin rules at HTS General Note 3(c) Authority.
Informational lookup only — not legal, customs, or compliance advice. Verify official FTA eligibility with U.S. Customs and Border Protection (CBP) and a licensed customs broker before claiming preference on entry.
