Antidumping and countervailing duty orders have been applied to certain copper pipe fittings from specific countries in the past. Importers must check the current CBP ADD/CVD order list before entry, as scope, rates, and covered countries can change through administrative reviews. A scope ruling request to CBP is advisable when a product's specifications or origin are borderline.
Refined copper fittings (7412.10) are made from commercially pure copper, while copper alloy fittings — including brass — classify under 7412.20. The alloy composition on the manufacturer's certificate or test report is the controlling document. Misidentifying a brass fitting as refined copper, or vice versa, can result in incorrect duty payment and potential CBP penalties.
