U-listed waste
Dibenzo[a,i]pyrene
U-list unused product.
ComplyOnSiteIs U064 hazardous waste?
Yes, when the listing applies. U064 covers dibenzo[a,i]pyrene thrown away unused, including off-specification product and qualifying residues. It is a U-listed waste, not an acute P-listed one. The listing depends on the product and how it is discarded, not on a TCLP result alone.
U064 is nonacute hazardous waste. On a required hazardous waste manifest, put U064 in Item 13. VSQG exemptions and empty-container rules and pharmaceutical containers still apply.
What does U064 cover?
This covers dibenzo[a,i]pyrene discarded unused, either pure or technical grade or as the only active ingredient in a formulation. It also covers off-specification batches, residues in nonempty containers and spill cleanup residues of those products. Inactive ingredients in the formulation don't affect this.

Is waste dibenzo[a,i]pyrene always U064?
| Code | When it fits |
|---|---|
| U064 | The unused chemical is thrown away, pure or technical grade or as the sole active ingredient. Residues from those products count too. |
| Characteristic waste (D001–D043) | A used chemical or a different formulation shows a hazardous characteristic. Process listings can apply too. |
A listed unused product can also have a characteristic, so more than one row can apply. Merely finding this chemical in a manufacturing waste doesn't make it U064. Match the waste's origin, formulation and use history. Mixing listed waste with solid waste, or treating it, generally doesn't remove the listing. That takes an exclusion, an exception or an approved delisting.
