Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not specifically from leaded gasoline or anti-knock compounds
General lead-containing residues without specific leaded fuel origin use broader subheading.
If classified primarily as petroleum residue
High hydrocarbon content may lead to petroleum waste classification in Chapter 27.

Import Tips & Compliance
• Use certified labs for zinc content assay to meet statistical note requirements without deductions
• Provide evidence of industrial end-use to qualify under heading 2620 chapter note
• Watch for environmental regulations on leaded residues; prepare import permits if required
