Products classified under HTS 2620.21.00.10
Leaded Gasoline Sludge with Copper Residue
Residue from the refining of leaded gasoline containing primarily lead compounds along with significant copper content from anti-knock additives. Classified under HTS 2620.21.00.10 as leaded gasoline sludges with copper content, fitting Chapter 26 for slag, ash, and residues used in metal extraction.
Leaded Anti-Knock Compound Sludge with Copper Impurities
Sludge generated from leaded anti-knock fuel additives production, rich in lead with copper from catalyst contamination. Falls under HTS 2620.21.00.10 for its copper content in leaded sludges, used industrially for lead and copper recovery per Chapter 26 notes.
Copper-Bearing Leaded Fuel Refinery Sludge
Hazardous sludge from leaded fuel refinery tanks, primarily lead-based with copper from alloy corrosion and additives. HTS 2620.21.00.10 applies to its copper content in leaded gasoline sludges, designated for industrial metal recovery as per chapter provisions.
Leaded Aviation Gasoline Sludge Containing Copper
Sludge from storage and processing of leaded aviation fuel (avgas), containing lead tetraethyl with copper impurities. Classified in HTS 2620.21.00.10 due to copper content in leaded sludges, used for extracting metals per heading 2620 scope.
Industrial Leaded Anti-Knock Sludge with Recovered Copper
Partially processed sludge from anti-knock compound manufacturing, mainly lead with assayed copper for recovery. HTS 2620.21.00.10 captures its copper content in leaded sludges intended for chemical compound production.
