Leaded Gasoline Sludge with Silver Residue
Residue from the refining of leaded gasoline containing mainly lead along with silver compounds and arsenic traces. Classified under HTS 2620.21.00.40 due to its primary lead content and reportable silver assay, used for metal recovery in industrial processes. Excludes municipal waste incineration residues per Chapter notes.

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 from 2620, directing to heading 2621 for other slag/ash.
If containing mainly antimony instead of lead
Heading 2617 covers slag/ash with mainly antimony; material composition shifts classification.
If reprocessed into usable electrical waste form
If reworked beyond crude residue into electrical scrap, moves to Chapter 85 as waste of electrical goods.

Import Tips & Compliance
• Report exact silver assay quantity without deductions as per statistical notes; provide lab certificates
• Classify as hazardous waste under EPA/DOT; obtain proper TSCA and RCRA documentation
• Avoid misclassification as iron/steel slag (Chapter 26 excl.); verify no municipal waste origin
