Warfarin is on the EPA's P‑list (i.e., an acutely hazardous commercial chemical product), not a K‑listed waste.

Notes:
- The P‑list and K‑list are in 40 CFR 261.33 (P‑list entries are commercial chemical products that are acutely hazardous when discarded).
- The P‑listing generally applies to unused commercial chemical products and their container residues; wastes containing warfarin that result from patient use (e.g., bodily fluids) or that are diluted/disposed differently may be regulated differently.
- Always confirm management requirements with the product SDS and your state/local hazardous waste authority (and 40 CFR 261.33) because specific handling, exemptions, and disposal options can vary.
