Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If residual oil content dominates over metals
Waste oils from fuel refining classify under petroleum residues in Chapter 27, not metal slags.
If other metal compounds not mainly lead
Residues with mixed or other primary metals fall into the general 'other' subheading of 2620.99.

Import Tips & Compliance
• Distinguish from unleaded sludges; documentation must specify leaded origin to fit 2620.21
• Comply with aviation fuel residue regs; FAA or equivalent certs aid customs clearance
• Watch for re-export requirements on high-arsenic batches under Basel Convention
