Leaded Gasoline Sludge Residue
Residue generated from the cleaning of storage tanks that previously held leaded gasoline, containing primarily lead compounds from tetraethyllead additives. Classified under HTS 2620.21.0020 due to its high lead content and origin as a sludge from leaded fuel processing, fitting Chapter 26 notes for metal-containing residues used in extraction.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If derived from municipal waste incineration
Chapter notes exclude incineration residues from heading 2620, directing to 2621 for non-industrial ash.
If processed into electrical waste form
Repurposed residues resembling electrical scrap fall under Chapter 85 for waste of electrical machinery.
If sold as a chemical waste mixture for recovery
Broad residual chemical wastes not specifically metallurgical residues shift to Chapter 38 heading.

Import Tips & Compliance
• Obtain assay certificates verifying lead content without deductions, as per statistical notes, for accurate reporting
• Ensure hazardous waste manifests and EPA compliance documentation for transboundary movement under Basel Convention
• Avoid misclassification as municipal waste ash (2621); confirm industrial origin to prevent duty disputes
