Last updated: August 2026 dataSemi-fabricated copper and copper-alloy products produced by rolling, drawing, and extruding — classified under NAICS 331420 — serve as the direct upstream inputs for electrical, plumbing, automotive, and industrial manufacturing. Brass mill products (rod, bar, and tube) and copper sheet and strip are among the most widely traded forms, with product specifications governed by ASTM standards that define alloy designation, temper, and dimensional tolerances. Trade professionals importing these products must navigate HTS classification based on alloy type and product form, and should monitor antidumping activity in this product space, which has historically attracted trade-remedy petitions.
