As Chinese manufacturing enterprises expand into Southeast Asia, they have achieved greater diversification in both production and export channels. However, this shift simultaneously introduces more complex requirements regarding trade compliance and Rules of Origin (ROO). For companies primarily targeting the U.S. market, it is crucial to stay abreast of real-time U.S. tariff policies and origin requirements concerning Southeast Asian countries. In many cases, it is necessary to apply for a Binding Ruling on country of origin from U.S. Customs and Border Protection (CBP) prior to exporting goods to the United States.
