Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If >50% benzene content
Benzol-rich residues qualify under aromatic subheadings.
If phenol isolation achieved
Purified phenols become Chapter 29 organic chemicals.

Import Tips & Compliance
• Analyze for phenol/BTEX content; >1% shifts regulatory requirements
• Require phenolic resin production contracts for commercial justification
• Use stainless steel containment due to corrosive acidic components

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.
