Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If lacks mercury/arsenic/thallium but contains other metals
Shifts to 'other' arsenic/metal residues subheading without specified toxic elements.
If waste from electrical apparatus dismantling
Mercury from spent batteries/lamps classified under Chapter 85 electrical waste, not metallurgical slag.
If from lead battery recycling
Lead-acid battery ash/residues fall under specific 2621 subheading for recovery operations.

Import Tips & Compliance
• Declare exact metal content via assay; statistical notes mandate no deductions for quantity reporting
• Secure Basel Convention prior informed consent for transboundary mercury waste movements
• Avoid common pitfall of bulk packaging without stabilization, risking hazardous material reclassification
