Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other residues not meeting 2620 industrial use criteria
Catch-all for non-specified residues, excluding 2620's extraction/compound manufacture.
If classified as copper ores rather than processed residue
Raw copper ores in Chapter 26 heading 2603 precede processed slags.
If chemically treated for compound production
Prepared chemical products from residues may shift to Chapter 38.

Import Tips & Compliance
• Declare full chemical composition including any arsenic to meet 2620 notes
• Obtain pre-shipment inspections for metal content verification
• Beware of reclassification if sold in sets with processing equipment
