Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mainly zinc rather than lead
Zinc-dominant sludges from similar processes are grouped under the zinc subheading in 2620.19.
If derived from municipal waste incineration
Chapter note excludes incineration ash from 2620, directing it to heading 2621 for other ash and residues.
If considered waste from electrical/metal production equipment
Residues from spent catalysts or electrodes may classify as electrical waste parts under Chapter 85.

Import Tips & Compliance
• Report metal content based on assay without deductions; include certificates of analysis in customs documentation
• Ensure sludge qualifies under heading 2620 by proving use in metal extraction, not incineration residues
• Check for arsenic content declarations to avoid reclassification; common pitfall is incomplete hazardous material manifests
