Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily zinc content with copper secondary
Statistical breakout within 2620.21 shifts based on main metal (lead vs zinc) despite copper presence.
If from uranium or thorium processing
Certain metal-bearing residues from nuclear fuel are classified under 2619, distinct from leaded fuel sludges.
If refined into antimonial lead compounds
Processed chemical compounds of metals move from residues (2620) to inorganic chemicals in Chapter 28.

Import Tips & Compliance
• Provide end-use certificates confirming industrial application for metal or compound manufacture to justify 2620 classification
• Conduct particle size and composition testing; misreported copper content leads to penalties
• Package in UN-approved containers for hazmat; bulk shipments require special customs bonds
