RCRA Hazardous Waste (US, 40 CFR 261)

What is the RCRA waste code for Hydraulic Fluid?

Used hydraulic fluid is hazardous if it is ignitable (D001 if flash point below 60C) or contains heavy metals. Recycled hydraulic fluid may not be RCRA hazardous.

Also searched as: hydraulic oil, hydraulic waste

Which Code Applies?

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

D001 D List

Mineral-based hydraulic oil (disposed)

Ignitable waste - liquids with flash point below 60 C (140 F), ignitable solids, oxidizers, and ignitable compressed gases

No code

Recycled/re-refined hydraulic fluid

Not RCRA hazardous if properly reclaimed

Simulate your D001 stream

Hydraulic Fluid

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.
