U.S. Customs regulations require that every article of foreign origin (or its container) imported into the United States shall be marked in a conspicuous place as legibly, indelibly and permanently as the nature of the article (or container) will permit, in such a manner as to indicate to the ultimate purchaser in the United States the English name of the country of the origin of the article, at the time of importation into the Customs territory of the United States. (Containers of articles excepted from marking shall be marked with the country of origin of the articles unless the container is also excepted from marking.) 美國海關要求每個外來商品 (或是外箱) 進口到美國,每個商品 (或是外箱) 都要有標示,標示處明顯清楚、擦不掉,就好像是商品 (或是外箱) 的一部分永遠存在。美國境內的最終購買者才能知道物品的原產國以及進入美國的時間點。(論商品外箱上的標示,外箱都要標示原產地,除非外箱也免除標示。)
