The United States-Japan Trade Agreement (USJTA) entered into force on January 1, 2020. Nearly 90 percent of U.S. food and agricultural products imported into Japan are now duty free or receive preferential tariff access. In order to receive preferential treatment, a good must be an originating good and meet the preferential rules of origin of USJTA. The laws, regulations, or procedures of Japan further specify how importers should comply with requests for additional information for products seeking preferential treatment. Exporters are not permitted to initiate the submission of any documents for origin procedures to Japan Customs. However, exporters may submit supplementary documents directly to Japan Customs in coordination with the importer. Final origin determination will be made by Japan Customs and U.S. exporters are encouraged to work closely with their importer to ensure all proper information has been made available.
