Leaded Gasoline Sludge with Zinc Residue
Residue generated from the cleaning of storage tanks that held leaded gasoline, containing mainly lead compounds along with significant zinc content from anti-knock additives. Classified under HTS 2620.21.0030 due to its origin from leaded fuel processing and metal content primarily lead with reportable zinc assay. Used in industry for metal recovery processes.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing mainly zinc rather than lead
Slags and residues shift to subheading for zinc content when lead is not the primary metal.
If from roasting or calcining of zinc-lead ores
Processing residues from ore treatment fall under heading 2619 instead of general slags.
If considered waste or scrap from electrical accumulators
Certain metal-containing sludges from battery production may classify as electrical waste rather than industrial residues.

Import Tips & Compliance
• Report zinc content as per assay quantity without deductions, as specified in statistical notes
• Verify the residue qualifies under Chapter 26 note for heading 2620 by confirming industrial use for metal or compound extraction
• Avoid misclassification as municipal waste ash (HTS 2621); provide documentation proving origin from leaded gasoline processing
