U185, Pentachloronitrobenzene (PCNB).
U-listed waste
Pentachloronitrobenzene (PCNB)
U-list unused product.
ComplyOnSiteIs U185 hazardous waste?
Yes, when the listing applies. U185 covers unused pentachloronitrobenzene (PCNB) thrown away as described below, including off-specification product and qualifying residues. It is a nonacute U-listed waste, not an acute P-listed one. The listing turns on the product and how it is discarded, not on a TCLP result alone.
On a required hazardous waste manifest, put U185 in Item 13. Also check the VSQG exemptions and empty-container rules and pharmaceutical containers.
What does U185 cover?
This covers unused pentachloronitrobenzene (PCNB) discarded as pure or technical grade, or in a formulation where it is the only active ingredient. That includes off-specification batches, residues in nonempty containers and cleanup residues from spills of these products. Inactive ingredients don't stop it counting as the sole active ingredient.

Is waste pentachloronitrobenzene (PCNB) always U185?
| Code | When it fits |
|---|---|
| U185 | The unused chemical is discarded as pure or technical grade, or as the sole active ingredient. Residues from that product count too. |
| Characteristic waste (D001–D043) | A used chemical or a different formulation meets a hazardous waste characteristic. Check any process listings that apply too. |
The rows can apply together, so a listed unused product can also exhibit a characteristic. This chemical turning up in a manufacturing waste doesn't make the waste U185. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, usually doesn't remove the listing. That takes an applicable exclusion, exception or approved delisting.
