Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from high-purity cathode production
Purer cathode trimmings (>94% Cu) classified under high-assay refined scrap subheadings.
If re-rolled into bars before export
Semi-processed into bars/billets moves from waste Chapter 74 to unwrought refined copper.
If containing recoverable platinum group metals
PGM-bearing refinery scrap classified as precious metal waste under Chapter 71.

Import Tips & Compliance
• Large flat pieces require special packing to prevent damage; use vermiculite for moisture control
• Confirm 'refined' status vs primary smelter trim (different subheading)
• Avoid mixing with No.1 copper scrap (>94% Cu) to prevent commingling penalties
