Last updated: April 2026 dataExtruded and drawn aluminum tubes and pipes are widely traded inputs for HVAC systems, heat exchangers, hydraulic lines, structural frameworks, and fluid-handling equipment across industrial and construction sectors. Alloy series, wall thickness, temper, and whether the product is seamless or welded are the specification variables that determine fitness for pressure-rated or structural applications. Like other semi-fabricated aluminum products, tubes and pipes are subject to Section 232 tariffs, and antidumping orders on aluminum extrusions from certain origins may overlap with this heading depending on scope language.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Active antidumping and countervailing duty orders on aluminum extrusions from certain countries can cover hollow profiles that overlap with tubes and pipes. Whether a specific product falls within an order's scope depends on its dimensions, alloy, and end-use finish. Importers should request a scope ruling from the Department of Commerce or consult a trade attorney if there is any ambiguity.
Mill test certificates (MTCs) issued by the producing mill are the standard documentation, showing alloy designation (e.g., 6061-T6), chemical composition, mechanical properties, and dimensional tolerances. CBP may request these at entry, and buyers in pressure-rated applications often require third-party inspection reports as well.
