Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Chapter note excludes such ash/residues, directing them to heading 2621 for other slag/ash.
If from iron or steel manufacturing
Full hierarchy specifies exclusion of iron/steel byproducts, which fall under 2619 for slag with metals.
If processed into zinc dross or skimmings
Advanced processing changes it from residue to zinc waste/scrap under Chapter 79 for unwrought zinc.

Import Tips & Compliance
• Report zinc content as assay quantity without deductions per statistical notes; provide lab assays for customs valuation
• Ensure documentation proves industrial use for metal extraction to avoid reclassification under waste headings
• Verify absence of municipal waste incineration origins to comply with heading 2620 exclusions
