Last updated: April 2026 dataRefined copper tube and pipe fittings — elbows, tees, couplings, and reducers used to join copper piping systems — are widely specified in plumbing, HVAC, and medical gas installations for their solderability and corrosion resistance. The entire heading classifies under a single 10-digit line (7412100000), but importers should note that these fittings may be subject to antidumping or countervailing duty orders depending on country of origin. Germany leads US supply, with South Korea and Italy also significant sources.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
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.
