    Prosulfocarb — a thiocarbamate herbicide

U-list unused product.

Toxic U-listed hazardous waste for unused prosulfocarb, a thiocarbamate herbicide, listed when thrown away as unused product.

Is U387 hazardous waste?

Yes, when the listing applies. U387 is the U-listed code for unused prosulfocarb thrown away, including off-specification product and qualifying residues. It is nonacute, not a P-listed acute waste. It depends on the product and how it is discarded, not on a TCLP result.

On a required hazardous waste manifest, put U387 in Item 13. Read the VSQG exemptions and empty-container rules and pharmaceutical containers too.

What does U387 cover?

This takes unused prosulfocarb that is pure, technical grade or the only active ingredient of a product. That includes off-specification batches, residues left in non-empty containers and spill cleanup residues. Inactive ingredients don't affect the only-active-ingredient test.

Is prosulfocarb waste always U387?

CodeWhen it fits
U387The unused chemical is thrown away pure, in technical grade or as the only active ingredient. Qualifying product residues are included.
Characteristic waste (D001–D043)A used chemical or a different formulation has a hazardous characteristic. Assess any process listings too.

Both rows can apply to one waste, because a listed unused product can also have a characteristic. The chemical merely turning up in a manufacturing waste doesn't make the waste U387. Match the waste’s origin, formulation and use history. Mixing or treating listed waste doesn't generally remove the listing. That takes an exclusion, an exception or an approved delisting.
