RCRA Hazardous Waste (US, 40 CFR 261)

What is the RCRA waste code for Used Oil?

Used oil destined for recycling is managed under 40 CFR Part 279, not as hazardous waste. Disposed used oil is hazardous only if it exhibits a characteristic (D001 if ignitable, D008 if lead exceeds TCLP threshold).

Also searched as: waste oil, used motor oil, used lubricating oil, gear oil waste

Which Code Applies?

RCRA classifies waste by source, process, and characteristics — not just material. Pick the row that matches how your used oil arises; each coded row links to the full waste code definition under 40 CFR Part 261.

Simulate your D001 stream

Used Oil

With a lab analysis, the engine checks the stream against each receiving route's published limits and returns what is supported, what is refused, and why. Without one yet, we tell you which routes it can evaluate and what analysis that needs.

What do you need?

An engineer replies within 1 business day. That reply confirms what is needed to run the dossier and when it can follow. A route the engine does not cover yet is reported as not yet evaluable, with the evidence that would change that.
