U.S. imports of aluminum alloy hollow profiles (HS 760421) totaled $46.9M in July 2026, traded with 67 countries.
Importers of Aluminum Alloy Hollow Profiles paid $23.2M in duties in July 2026 — an effective duty rate of 51% on $45.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Extruded hollow profiles in aluminum alloy are a foundational product for construction fenestration, transportation frames, and industrial structural systems, where the hollow geometry delivers strength-to-weight efficiency. The US schedule distinguishes heat-treatable industrial alloys (7604210010) from other hollow profiles (7604210090), a split that matters for antidumping and Section 232 analysis. Canada and Mexico lead supply, with Vietnam a notable third-tier source; USMCA origin rules apply to Canadian and Mexican material. Importers should monitor antidumping orders on aluminum extrusions from specific origins, as scope determinations for hollow profiles have been actively litigated.

The US has maintained antidumping and countervailing duty orders on aluminum extrusions from certain countries. Hollow profiles that fall within the scope of those orders require a separate AD/CVD entry and cash deposit at the applicable rate. Scope is defined by the order itself, and CBP scope rulings have addressed edge cases involving heat-treated alloys and specific end-use configurations — importers should request a scope ruling when product specifications are borderline.
Heat-treatable alloys are those in the 2xxx, 6xxx, and 7xxx series that gain strength through precipitation hardening after extrusion. The industrial designation further narrows to profiles intended for structural or mechanical applications rather than decorative use. Mill certifications identifying the alloy series and temper designation (e.g., T5, T6) are the primary documents used to support classification under 7604210010.
