Standard International Trade Classification
U.S. imports of Copper Alloy Plate, Sheet, and Strip Over 0.15 mm Thick (SITC 68252) totaled $53.9M in August 2026, imported from 38 countries.
Importers of Copper Alloy Plate, Sheet, and Strip Over 0.15 mm Thick paid $22.9M in duties in August 2026, an average duty rate of 42.49% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataBrass, bronze, and cupronickel flat-rolled products thicker than 0.15 mm are critical materials for coinage blanks, marine hardware, condenser tubing substrates, decorative architectural panels, and ammunition cartridge cases — end uses that demand tight alloy and temper tolerances. The alloy family (brass vs. bronze vs. cupronickel) and the zinc or tin content percentage are the primary specification variables that differentiate products within this heading and drive end-use suitability. Importers should be aware that certain copper alloy flat-rolled products have attracted antidumping scrutiny, and the country of origin combined with the specific alloy can determine trade-remedy exposure. Thickness certification above the 0.15 mm foil boundary is required to support correct classification.

If the flat-rolled product contains alloying elements (zinc, tin, nickel, etc.) in proportions that make copper the predominant metal by weight but not the sole significant constituent, it classifies as copper alloy sheet rather than refined copper sheet. Mill test certificates documenting the elemental breakdown are the standard evidence; importers should retain these records in case of a CBP inquiry.
Ammunition cartridge brass, coinage blanks, and marine condenser applications each require distinct alloy grades and tempers, and these sectors often have cyclical or government-contract-driven demand patterns. Importers supplying these markets should plan for longer lead times on specialty alloys and consider maintaining safety stock, as mill production runs for narrow-tolerance alloy strip can be infrequent.
