The International Trade Commission publishes updates to the Harmonized Tariff System of the United States (HTSUS) twice per year in January and July. Accurate classification and valuation of imported goods are essential. The Harmonized codes and descriptions filed upon entry determine duty rates or duty free status. Harmonized tariff descriptions also give Customs and Border Protection (CBP) information about what commodities are entering the country and determine if any other agencies such as the FCC or FDA also have jurisdiction. An annual review of your HTSUS codes and database update is a good business practice. Contact your broker or Ad Hoc Logistics if you need help.
