Products classified under HTS 2620.21.00.20
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.
Leaded Paint Manufacturing Sludge
Waste sludge from lead pigment production in paint factories, containing high lead content from lead chromate or oxide. Classified in HTS 2620.21.0020 for lead-main sludges akin to leaded gasoline types, used industrially for metal recovery per chapter notes.
Aviation Leaded Fuel Tank Sludge
Sludge extracted from aircraft fuel tanks using leaded avgas (avgas 100LL), containing lead alkyls and particulates. Fits HTS 2620.21.0020 as leaded gasoline sludges with primarily lead content for industrial extraction uses.
Historical Leaded Battery Processing Sludge
Legacy sludge from older lead-acid battery recycling plants using leaded compounds, high in metallic lead. HTS 2620.21.0020 for lead-main content residues not from iron/steel, suitable for metal recovery per notes.
Leaded Anti-Knock Compound Sludge
Sludges from the production and storage of lead-based anti-knock additives like tetraethyllead for gasoline, rich in lead metal content. Falls under HTS 2620.21.0020 as residues containing mainly lead, per chapter notes for industrial use in metal extraction or chemical manufacture.
Tank Bottom Sludge from Leaded Fuel
Accumulated sludge from the bottom of underground storage tanks used for leaded aviation gasoline, primarily leaded compounds. HTS 2620.21.0020 applies as lead-content sludges from leaded anti-knock compounds, aligning with notes for arsenic/metal residues in industry.
Refinery Leaded Additive Residue
Residues from oil refinery distillation columns handling leaded anti-knock additives, predominantly lead sludge. HTS 2620.21.0020 covers such lead-content sludges from leaded gasoline/compound processing for industrial metal/compound recovery.
Leaded Stabilizer Production Ash
Ash residues from manufacturing lead-based PVC stabilizers, containing lead salts and metals. Classified under HTS 2620.21.0020 as lead-content ash/slags for chemical compound production, per chapter heading 2620 scope.
