U-list unused product.
ComplyOnSiteIs U107 hazardous waste?
Yes, when the listing applies. U107 is a nonacute U-listed hazardous waste, not an acute P-listed one. It covers unused di-n-octyl phthalate thrown away, including off-specification product and qualifying residues. The listing depends on the product and how it is discarded, not on a TCLP result alone.
Put U107 in Item 13 of a required hazardous waste manifest. The VSQG exemptions and empty-container rules and pharmaceutical containers still apply.
What is U107 waste?
It covers unused di-n-octyl phthalate thrown away in 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 count too. Inactive ingredients don’t change that.

Is di-n-octyl phthalate waste always U107?
| Code | When it fits |
|---|---|
| U107 | The unused chemical is thrown away pure, technical grade or as the sole active ingredient. Qualifying product residues fit too. |
| Characteristic waste (D001–D043) | A used chemical or a different formulation has a hazardous-waste characteristic. Any process listing that fits can apply too. |
The rows can apply together, since a listed unused product can also have a characteristic. A manufacturing waste isn’t U107 just because it contains this chemical. Match the waste’s origin, formulation and use history. Mixing or treating listed waste doesn’t generally remove the listing. That takes an exclusion, an exception or an approved delisting that fits.
