U025, Dichloroethyl ether.
U-listed waste
Dichloroethyl ether
U-list unused product.
ComplyOnSiteIs U025 hazardous waste?
Yes, when the listing applies. U025 covers the unused dichloroethyl ether described below when it is discarded, including off-specification product and qualifying residues. It is a U-listed waste, not an acute P-listed one. The listing depends on the product and how it is discarded, not on a TCLP result alone.
U025 is nonacute hazardous waste. On a required hazardous waste manifest, put U025 in Item 13. See VSQG exemptions and empty-container rules and pharmaceutical containers.
What does U025 cover?
This covers unused dichloroethyl ether discarded in pure or technical grade, or in a formulation where it is the only active ingredient. It also covers off-specification batches, residues in nonempty containers and spill cleanup residues from those products. Inactive ingredients don't stop dichloroethyl ether counting as the sole active ingredient.

Is dichloroethyl ether waste always U025?
| Code | When it fits |
|---|---|
| U025 | The unused chemical is discarded as a pure or technical grade product or as the sole active ingredient. Residues from that product also count. |
| Characteristic waste (D001–D043) | A used chemical or a different formulation meets a hazardous-waste characteristic. Check any process listings that apply too. |
Both can apply, since a listed unused product can also show a characteristic. Having this chemical in a manufacturing waste doesn't make the waste U025. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, doesn't normally remove the listing. Only an exclusion, an exception or an approved delisting does.
