U.S. imports of aluminum sheets, plates & foils (NAICS 331315) totaled $672.8M in July 2026, traded with 57 countries.

Last updated: July 2026 dataFlat-rolled aluminum — encompassing heavy plates used in aerospace and marine structures, sheet stock for automotive body panels and building products, and thin foil for packaging — is one of the most actively traded fabricated aluminum forms in US commerce. NAICS 331315 covers the rolling mills that produce these products from cast slabs, and the resulting goods span a wide range of tempers, alloy series, and thickness tolerances that determine end-use suitability. Section 232 tariffs apply to imported flat-rolled aluminum, and antidumping or countervailing duty orders on specific flat-rolled products from certain origins add another layer of duty exposure that importers must evaluate at the HTS line level.

7.2K shipments/mo
Aluminum flat-rolled products are classified in the HTS based on alloy series (e.g., 1xxx, 3xxx, 5xxx, 6xxx), thickness, and whether the product is in coil or cut-to-length form. Temper designations (such as H or T tempers) affect end-use suitability but are not always determinative for HTS classification; however, they are critical for meeting ASTM or aerospace material specifications that buyers require.
Yes. In addition to Section 232 tariffs, antidumping and countervailing duty orders have been imposed on common alloy aluminum sheet from several countries. Importers should check the current scope of any active orders with CBP or the Department of Commerce, as scope rulings can determine whether a specific product form and alloy combination is covered.
