Acute hazardousP-listed waste
Toxaphene — an insecticide

P-list unused product.

Acute hazardous P-listed waste for unused toxaphene, a toxic organochlorine insecticide once used on cotton.

Is P123 hazardous waste?

Yes, when the listing applies. P123 covers discarded, unused toxaphene, 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 P123 in Item 13. For exceptions, use the VSQG exemptions and empty-container rules and pharmaceutical containers.

What does P123 cover?

This listing covers unused toxaphene 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 toxaphene always P123?

Code	When it fits
P123	The unused chemical is discarded as pure or technical grade, or as the sole active ingredient. Qualifying product residues count too.
D015	The waste’s TCLP extract holds toxaphene at 0.5 mg/L or more. The product listing can apply as well.
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 P123. 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.

Which wastes take P123?

Waste	When it’s P123
