Products classified under HTS 2713.90.00.00
Petroleum Refinery Slop Oil
Slop oil is a residual petroleum product recovered from refinery wastewater treatment processes, containing hydrocarbons from petroleum oils. It falls under HTS 2713.90.00.00 as a residue of petroleum oils not suitable for direct fuel use without further processing. This heavy, contaminated oil is typically reprocessed for recovery of valuable components.
Clarified Sludge Oil from Tank Bottoms
Tank bottom sludge is the heavy sediment accumulated in petroleum storage tanks, clarified to recover oil residues from bituminous materials. Classified under HTS 2713.90.00.00 as it represents unprocessed residues unsuitable for immediate use. Used primarily in asphalt production or as fuel oil feedstock.
Heavy Fuel Oil Tank Residue
Residue remaining in tanks after heavy fuel oil (HFO) drainage, consisting of petroleum oil bottoms from bituminous sources. Falls under HTS 2713.90.00.00 as 'other residues' too viscous for standard fuel use. Commonly blended into lower-grade bunker fuels.
Asphalt Flux Residue
Residue from vacuum distillation towers used as asphalt flux feedstock, derived from petroleum oils or bituminous materials. HTS 2713.90.00.00 applies to these unrefined heavy ends before fluxing. Essential for road paving asphalt production.
Petroleum Desalter Brine Sludge
Emulsion-breaking sludge from crude oil desalters, containing petroleum oil residues emulsified with brine. Classified in HTS 2713.90.00.00 as residues of petroleum oils from bituminous minerals. Recovered for oil reclamation before disposal.
Vacuum Residuum from Crude Distillation
Bottoms product from vacuum crude distillation units, the heaviest residue of petroleum oils. HTS 2713.90.00.00 covers this material before coking or further processing. Primary feedstock for coker units and heavy fuel production.
API Separator Sludge Oil
Hydrocarbon sludge recovered from API oil-water separators in refineries, residue of petroleum processing. Falls under HTS 2713.90.00.00 as other petroleum oil residues. Reprocessed for fuel or asphalt blending.
Coker Quench Oil Residue
Heavy hydrocarbon residue from delayed coker quench towers, derived from petroleum vacuum resid. HTS 2713.90.00.00 classification for these unrecoverable bottoms. Contains pitch-like materials from bituminous oil processing.
Lube Oil Filter Cake Residue
Carbonaceous residue from filtering used lubricating oils recovered during re-refining. Classified under HTS 2713.90.00.00 as petroleum oil processing residue. Contains spent additives and heavy hydrocarbons.
Sour Water Stripper Bottoms
Heavy tar-like residue from stripping hydrocarbon contaminants from refinery sour water. HTS 2713.90.00.00 covers these petroleum oil residues containing phenols and BTEX. Source for specialty chemical recovery.
Crude Oil Emulsion Breaker Residue
Bottoms from chemical demulsification of crude oil/water emulsions, containing asphaltenes and resins. Falls under HTS 2713.90.00.00 as residue from petroleum oil processing. Used in drilling mud formulations.
Visbreaker Tar Residue
Tar bottoms from visbreaking units thermally cracking vacuum residue to produce heavy fuel oil. HTS 2713.90.00.00 classification for these uncracked petroleum residues. Further processed into asphalt or fuel.
Diesel Hydrotreater Purge Residue
Heavy polynuclear aromatics purged from diesel hydrotreating units to maintain product specs. Classified HTS 2713.90.00.00 as petroleum oil residue from bituminous materials. Valuable asphalt modifier feedstock.
Alkylation Unit Spent Acid Sludge
Hydrocarbon-rich sludge from HF alkylation unit acid settler bottoms containing petroleum residues. HTS 2713.90.00.00 covers the organic layer separated from spent sulfuric/HF acid. Recovered for fuel value.
FCC Slurry Oil
Heavy catalytically cracked slurry oil from Fluid Catalytic Cracker bottoms carrying catalyst fines. Falls under HTS 2713.90.00.00 as residue of petroleum oil processing from bituminous materials. Used in asphalt and carbon black production.
