Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If from municipal waste incineration
Chapter note excludes such ash from 2620; falls under heading 2621 for incineration residues.
If primarily lead or zinc smelter residues
If dominant metal is lead/zinc rather than antimony mix, shifts to Chapter 26 slag for those metals.
If processed into chemical waste mixtures
Further refinement into non-metal-extraction compounds moves to Chapter 38 for industrial residues.

Import Tips & Compliance
• Verify assay certificates for antimony and metal content to meet statistical reporting without deductions
• Ensure documentation proves industrial use for metal extraction to avoid reclassification under waste codes
• Comply with hazardous material regulations if cadmium or chromium levels trigger EPA scrutiny
