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.
Hemophagocytic lymphohistiocytosis (HLH) is a rare disease that usually occurs in infants and young children. It may also occur in adults. Children usually inherit the disease. In adults, many different conditions, including infections and cancer, can cause HLH. If you have HLH, your body's defense system, called your immune system, does not work normally. Certain white blood cells â histiocytes and lymphocytes â attack your other blood cells.
