P043, Diisopropylfluorophosphate (DFP).
Acute hazardousP-listed waste
Diisopropylfluorophosphate (DFP)
P-list unused product.
ComplyOnSiteIs P043 hazardous waste?
Yes, when the listing applies. Unused diisopropylfluorophosphate (DFP) thrown away is P043, 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 P043 in Item 13. The VSQG exemptions and empty-container rules and the rules for pharmaceutical containers may also matter.
What does P043 cover?
This covers unused diisopropylfluorophosphate (DFP) 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 diisopropylfluorophosphate (DFP) waste always P043?
| Code | When it fits |
|---|---|
| P043 | The 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 P043. 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.
Which codes sit beside P043?
| Code | What it is |
