K-listed waste
Bottom distillation residue from making nitrobenzene

Industry: Organic chemicals.

Toxic K-listed waste from organic chemical plants. Distillation bottoms from making nitrobenzene by nitrating benzene.

Is K025 hazardous waste?

Yes. K025 is nonacute hazardous waste when your waste comes from the named process and stream. The federal table gives it hazard code (T), for toxicity.

A K listing follows how and where the waste arose, not a concentration test. A test may add a characteristic code, but it doesn't remove this listing.

On a required hazardous waste manifest, put K025 in Item 13. Check the VSQG exemptions and empty-container rules too.

What does K025 cover?

This listing covers distillation bottoms from producing nitrobenzene by the nitration of benzene. The waste form and the source process must both match this listing. Chemical content alone isn't enough.

Hazard code: (T), toxicity

Are nitrobenzene distillation bottoms always K025?

Code	When it fits
K025	It is distillation bottoms from producing nitrobenzene by the nitration of benzene.
K024	It is distillation bottoms from producing phthalic anhydride from naphthalene.
K023	It is distillation light ends from producing phthalic anhydride from naphthalene.

The industry, production step and waste form tell these K listings apart, not chemical content. The rows show nearby listed streams, not every code that could apply. Add any characteristic or other listing that also fits, because a waste can carry several federal codes.

Which wastes take K025?
