美国海关从属于美国财政部,其主要职能是:估算并征收进口商品的关税、国内税及其它一切费用;实施关税法律及其它相关法律;执行某些航运法律和条约。海关作为主要的实施机构,负责辑查走私物品和执行众多联邦机构制定的有关规则。中药产品一般是作为膳食补充剂进入美国的,因此应熟悉美国的进口法律和海关规定。 The U.S. Customs Department is subordinate to the U.S. Department of the Treasury. Its main functions are: to estimate and collect customs duties, domestic taxes and all other costs on imported goods; to impose tariff laws and other relevant laws; and to enforce certain shipping laws and treaties. The Customs, as the main implementing agency, is responsible for compiling smuggled goods and implementing the relevant rules set by numerous federal agencies. Traditional Chinese medicine products generally enter the United States as a dietary supplement and should therefore be familiar with U.S. import laws and customs regulations.
