Definition & Explanation

Exporters and customs agents rely on Form AJ to certify preferential origin for goods traded between ASEAN member states and Japan under the ASEAN–Japan Comprehensive Economic Partnership (AJCEP). Products that satisfy the agreement's rules of origin qualify for negotiated tariff reductions or full duty elimination on import. The form is issued, signed, and endorsed by the competent authority in the exporting country and travels with the shipment through customs clearance at destination. Without valid Form AJ, preferential status is lost and standard MFN duty rates apply. It should not be confused with Form D, which covers intra-ASEAN trade only.
