U-listed waste
Cyclophosphamide — a chemotherapy drug

U-list unused product.

U-listed hazardous waste for unused cyclophosphamide, a chemotherapy drug. Pharmacies & hospitals are the usual sources.

Is U058 hazardous waste?

Yes, when the listing applies. U058 covers cyclophosphamide thrown away unused, 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.

U058 is nonacute hazardous waste. On a required hazardous waste manifest, put U058 in Item 13. VSQG exemptions and empty-container rules and pharmaceutical containers still apply.

What does U058 cover?

This covers cyclophosphamide discarded unused, either pure or technical grade or as the only active ingredient in a formulation. It also covers off-specification batches, residues in nonempty containers and spill cleanup residues of those products. Inactive ingredients in the formulation don't affect this.

Is waste cyclophosphamide always U058?

Code	When it fits
U058	The unused chemical is thrown away, pure or technical grade or as the sole active ingredient. Residues from those products count too.
Characteristic waste (D001–D043)	A used chemical or a different formulation shows a hazardous characteristic. Process listings can apply too.

A listed unused product can also have a characteristic, so more than one row can apply. Merely finding this chemical in a manufacturing waste doesn't make it U058. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing. That takes an exclusion, an exception or an approved delisting.

Which wastes take U058?

Waste	When it’s U058
Waste pharmaceuticals	Unused cyclophosphamide is thrown away and is the only active ingredient.
Waste chemotherapy drugs	Discarded unused commercial product with cyclophosphamide as its only active ingredient.
