A factoid is either a false or spurious statement presented as a fact[1][2] or a true, but brief or trivial, item of news or information.
The Harmonized Tariff System (HTS) provides duty rates for virtually every item that exists. The HTS is a reference manual that is the size of an unabridged dictionary. The HTS - tariff database, is an interactive data base that will enable you to get an approximate idea of the duty rate for a particular product. CBP will make the final determination of what the correct rate of duty is, not the importer.
An HS code or HTS code stands for Harmonized System or Harmonized Tariff Schedule. Developed by the World Customs Organization (WCO), the codes are used to classify and define internationally traded goods. In most cases, in order to import or export a product internationally, the traded good must be assigned an HTS code that corresponds with the Harmonized Tariff Schedule of the country of import.
