Acute hazardousF-listed waste
Waste from making or manufacturing use of pentachlorophenol

F-list process waste.

Acute hazardous F-listed waste. Residues from making or using pentachlorophenol, or the derivatives made from it.

Is F021 hazardous waste?

Yes. F021 is an acute F-listed hazardous waste when the named source process and waste stream match. The federal table gives it hazard code H for acute hazard.

F021 is listed by source, so how and where the waste arose decides it, not a concentration test alone. A test can add a characteristic code but doesn't remove the listing once its conditions are met. On a required hazardous waste manifest, put F021 in Item 13. Look up the VSQG exemptions and empty-container rules too.

What does F021 cover?

Waste from making pentachlorophenol, or from using it in manufacturing as a reactant, intermediate or part of a formulating process. It also covers intermediates used to make its derivatives. It excludes wastewater and spent carbon from hydrogen chloride purification.

Hazard code: H for acute hazard
Rule: 40 CFR 261.31

Is pentachlorophenol process waste F021, F020 or F023?

Code	When it fits
F021	Waste from making pentachlorophenol, or using it in manufacturing as a reactant, intermediate or component of a formulating process.
F020	Waste from making tri- or tetrachlorophenol, or using it in manufacturing as a reactant, intermediate or component of a formulating process.
F023	Material was made on equipment formerly used to make or use tri- or tetrachlorophenol in manufacturing.

The operation and waste form pick the listing, not the chemical content alone. The rows show nearby listed streams, not every code that could apply. Add any characteristic or other listing that also fits, since one waste can carry more than 1 federal code.

Which wastes take F021?

Waste	When it’s F021
Dioxin-listed process waste	Production or manufacturing use involved pentachlorophenol or intermediates for its derivatives
