K023, Light distillation fractions from making phthalic anhydride from naphthalene.
K-listed waste
Light distillation fractions from making phthalic anhydride from naphthalene
Industry: Organic chemicals.
ComplyOnSiteIs K023 hazardous waste?
Yes. K023 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 K023 in Item 13. Check the VSQG exemptions and empty-container rules too.
What does K023 cover?
This listing covers distillation light ends from producing phthalic anhydride from naphthalene. The waste form and the source process must both match this listing. Chemical content alone isn't enough.

Is naphthalene-route phthalic light ends always K023?
| Code | When it fits |
|---|---|
| K023 | It is distillation light ends from producing phthalic anhydride from naphthalene. |
| K093 | It is distillation light ends from producing phthalic anhydride from ortho-xylene. |
| K024 | It is distillation bottoms 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 codes sit beside K023?
