What is the RCRA waste code for Hydraulic Fluid?

Name: SymbioFlows Platform
Availability: InStock
Author: SymbioFlows

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.

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
