P204, Physostigmine.
Acute hazardousP-listed waste
Physostigmine
P-list unused product.
ComplyOnSiteIs P204 hazardous waste?
Yes, when the listing applies. P204 covers discarded, unused physostigmine, including off-specification product and qualifying residues. The P listing makes it acute hazardous waste, so the stricter acute quantities apply even for a small amount of the chemical.
Where a hazardous waste manifest is required, put P204 in Item 13. For exceptions, use the VSQG exemptions and empty-container rules and pharmaceutical containers.
What does P204 cover?
This listing covers unused physostigmine discarded as pure or technical grade, or in a formulation where it is the only active ingredient. Off-specification batches, nonempty-container residues and spill cleanup residues from these products are included. Inactive ingredients don't stop the chemical counting as the sole active ingredient.

Is waste physostigmine always P204?
| Code | When it fits |
|---|---|
| P204 | 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 shows a hazardous-waste characteristic. Any process listings that fit apply too. |
A listed unused product can also show a characteristic, so more than one row can apply. Having this chemical somewhere in a manufacturing waste doesn't make the waste P204. Match the waste’s origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing unless an exclusion, exception or approved delisting applies.
