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.
