U-listed waste
Trichloroethylene

U-list unused product.

Toxic U-listed hazardous waste for unused trichloroethylene, a degreasing solvent known as TCE, listed as unused product.

Is U228 hazardous waste?

Yes, when the listing applies. U228 is a U-listed hazardous waste for unused trichloroethylene that is thrown away, including off-specification product and qualifying residues. It is nonacute, not an acute P-listed waste. The listing depends on the product and how it is discarded, not on a TCLP result alone.

On a required hazardous waste manifest, put U228 in Item 13. Also read VSQG exemptions and empty-container rules and pharmaceutical containers.

What does U228 cover?

This listing covers unused trichloroethylene thrown away as pure or technical grade, or in a product where it is the only active ingredient. That includes off-specification batches, residues left in nonempty containers and spill cleanup residues. Inactive ingredients don't change that.

CAS: 79-01-6
Table entries: Ethene, trichloro- / Trichloroethylene
Hazard codes in the record: T (toxic)
Rule: 40 CFR 261.33(f)

Is trichloroethylene waste always U228?

Code	When it fits
U228	The unused chemical is discarded as pure or technical grade, or as the sole active ingredient. Qualifying product residues count too.
D040	The waste’s TCLP extract holds trichloroethylene at 0.5 mg/L or more. The product listing can apply too.
F001	It is spent after use in degreasing, or is a still bottom from recovering that degreasing solvent.
F002	It is spent after solvent use, or is a recovery still bottom. Degreasing can bring in F001 as well.
Characteristic waste (D001–D043)	A used chemical or a different formulation meets a hazardous-waste characteristic. Assess any process listings that apply too.

A listed unused product can also exhibit a characteristic, so more than one row can apply. Having this chemical in a manufacturing waste doesn't make the waste U228. Match the waste’s origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing. It takes an applicable exclusion, exception or approved delisting.

Which wastes take U228?
