Import Tips

• Verify assay quantity of metal content without deductions for accurate statistical reporting per statistical notes

• Provide documentation certifying industrial use for metal extraction or chemical manufacture to avoid reclassification

• Ensure residues are not from municipal waste incineration, as those fall under 2621; common pitfall is mislabeling waste types
