Osmium tetroxide
P-list unused product.
ComplyOnSiteIs P087 hazardous waste?
Yes, when the listing applies. P087 is for unused osmium tetroxide that is thrown away, including off-specification product and qualifying residues. It is acute hazardous waste, so the stricter acute quantities apply even for a small amount.
Put P087 in Item 13 of a required hazardous waste manifest. The VSQG exemptions and empty-container rules and pharmaceutical containers have their own limits.
What does P087 cover?
It covers unused osmium tetroxide thrown away pure, at technical grade, or in a formulation where it is the only active ingredient. It also takes in off-specification batches, residues left in nonempty containers and cleanup residues from spills of these products. Inactive ingredients don't stop it counting as the only active ingredient.

Is osmium tetroxide waste P087 or another code?
| Code | When it fits |
|---|---|
| P087 | Thrown away unused, pure or technical grade, or as the only active ingredient. Qualifying product residues count too. |
| Characteristic waste (D001–D043) | A used chemical or a different formulation that meets a hazardous-waste characteristic. Any process listings that apply count too. |
Both rows can apply at once, because a listed unused product can also have a characteristic. Having this chemical in a manufacturing waste doesn't make the waste P087. Match the waste's origin, formulation and use history. Mixing or treating listed waste generally doesn't remove the listing. That takes an exclusion, an exception or an approved delisting.
