SITCSection 6
U.S. imports of unwrought aluminum alloys (SITC 68412) totaled $288.3M in April 2026, traded with 24 countries.
Importers of Unwrought Aluminum Alloys paid $135.2M in duties in April 2026 — an effective duty rate of 50% on $270.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Unwrought Aluminum Alloys imports of $288.3M in April 2026 ran 20% below the year-to-date monthly average of $362.1M.
Last updated: April 2026 dataUnwrought aluminum alloys — spanning the 1xxx through 8xxx series in ingot, billet, and T-bar form — are the dominant feedstock for the US extrusion, casting, and rolling industries, with each alloy series engineered for distinct mechanical and corrosion-resistance profiles. Section 232 tariffs apply broadly to aluminum imports, and the alloy designation (e.g., 6061, 3003, 5052) is commercially critical because downstream processors are typically locked into specific series by their product specifications. Canada is a structurally important supplier given integrated North American smelting capacity, and USMCA treatment may affect duty calculations for Canadian-origin material.

At the SITC level, all unwrought aluminum alloys fall under 68412 regardless of series. At the HTS 10-digit level, distinctions may exist based on alloy composition or form, so importers should verify the applicable tariff line for their specific alloy. The alloy series designation matters primarily for commercial and end-use specification purposes rather than for heading-level classification.
Unwrought status requires that the material not have been worked beyond casting or continuous casting — it should not exhibit characteristics of a wrought product such as a defined cross-section achieved by rolling or extrusion. Continuously cast rod or redraw rod, for example, may be classified as wire rod rather than unwrought alloy. Importers should ensure that the product form and production method are clearly documented to defend the unwrought classification if questioned by CBP.
