Last updated: July 2026 dataRefined copper tubes and pipes are a primary input for HVAC, refrigeration, plumbing, and medical gas systems, where high thermal conductivity and corrosion resistance are essential. The US schedule separates seamless tube — including a specific line for small-diameter coiled tube (OD 6–16 mm on spools, 7411101030) used in ACR applications — from non-seamless forms (7411105000). South Korea leads US supply, with Canada and Germany also significant; imports are subject to Section 232 tariff considerations applicable to copper articles.

Small-diameter seamless refined copper tube with an OD of 6 mm to not over 16 mm, supplied coiled on spools, is specifically captured under 7411101030 — a line targeting ACR (air conditioning and refrigeration) coil stock. Larger-diameter or straight-length seamless tube falls under 7411101090, and non-seamless forms under 7411105000. Confirming OD, wall thickness, and presentation (coil vs. straight) is essential for correct line selection.
Antidumping and countervailing duty orders have historically been applied to certain copper pipe and tube products from specific countries. Importers should check the current CBP ADD/CVD order list and USITC records before entry, as orders can be initiated, revoked, or modified through administrative reviews. A licensed customs broker can assist with scope rulings if the product's specifications are borderline.
