C11000 Electrolytic Tough Pitch Copper Strip from China

Narrow strip of C11000 ETP copper (99.9% pure copper), 0.3 mm thick by 250 mm wide, used in transformer windings and busbars. HTS 7409.90.90 applies to 'other copper alloys' plates/sheets under 5 mm thick and <500 mm wide; pure copper qualifies here absent specific refined copper headings.

Import Tips

Submit copper purity certificate (>99.9% Cu) distinguishing from alloy products; pure copper strips often scrutinized for heading 7409 vs 7408

Document coil/strip form factor; uncoiling during transit can trigger 'articles of copper' reclassification to 7415

Avoid common pitfall of declaring as 'foil' if >0.15 mm thick, which shifts to 7409 from 7407
