    Disulfoton — an organophosphate insecticide

P-list unused product.

Acute hazardous P-listed waste for unused disulfoton, a toxic insecticide that attacks the nervous system.

Is P039 hazardous waste?

Yes, when the listing applies. Unused disulfoton thrown away is P039, including off-specification product and qualifying residues. The P listing makes it acute hazardous waste, so the stricter acute quantities apply even to a small amount.

On a required hazardous waste manifest, put P039 in Item 13. The VSQG exemptions and empty-container rules and the rules for pharmaceutical containers may also matter.

What does P039 cover?

This covers unused disulfoton thrown away as pure or technical grade, or in a formulation where it is the only active ingredient. Off-specification batches, residues left in containers that aren’t empty, and spill cleanup residues from those products count too. Inactive ingredients don’t change the sole-active-ingredient test.

Is disulfoton waste always P039?

CodeWhen it fits
P039The unused chemical is thrown away, as pure or technical grade or as the sole active ingredient. Qualifying product residues fit too.
Characteristic waste (D001–D043)A used chemical or a different formulation meets a hazardous-waste characteristic. Check any process listings that apply too.

Both rows can apply at once, since a listed unused product can also show a characteristic. Having this chemical in a manufacturing waste doesn’t make that waste P039. Match the waste’s origin, formulation and use history. Mixing a listed waste with solid waste, or treating it, usually doesn’t remove the listing. That takes an exclusion, an exception or an approved delisting.
