General Headnote 3(A)
General Headnote 3(a)(iv) of the U. S. Harmonized Tariff Schedule provides a valuable trade status to Guam and other insular areas of the United States. Under the designation, product that are assembled or manufactured in Guam may enter the customs territory of the United States free of duty as long as they are in compliance with General Headnote 3(a)(iv) and applicable customs regulations.
Duty Free entry of these articles also requires them to be shipped directly to the customs territory of the United States and the articles are not subject to importation quotas. Customs regulations 19 CFR 7.3 requires that a Certificate of Origin for (Customs Form 3229) must be completed in connection with the entry of merchandise claimed free of duty under General Headnote 3(a)(iv). In determining whether an article is manufactured or produced within the scope of General headnote 3(a)(iv), a new and different article with a new name, character and use must result from the operations performed in Guam. In this respect, an article imported into the possession in a substantially complete condition does not, without extensive modifications further performed on it resulting in a new and different article of commerce, come within the scope of General Headnote 3(a)(iv).
