U218, Thioacetamide.
U-listed waste
Thioacetamide
U-list unused product.
ComplyOnSiteIs U218 hazardous waste?
Yes, when the listing applies. U218 is a U-listed hazardous waste for unused thioacetamide 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 U218 in Item 13. Also read VSQG exemptions and empty-container rules and pharmaceutical containers.
What does U218 cover?
This listing covers unused thioacetamide 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.

Is thioacetamide waste always U218?
| Code | When it fits |
|---|---|
| U218 | The unused chemical is discarded as pure or technical grade, or as the sole active ingredient. Qualifying product residues count too. |
| 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 U218. 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.
