    Propylene oxide

Use E140 when propylene oxide is present at >= 100.0 mg/kg by mass.

Waste holding propylene oxide at 100 mg/kg or more by mass. It is a flammable, toxic chemical used to make polyurethane and plastics.

Is Federal E140 hazardous waste?

Yes, if the listing and federal definition apply. Federal E140 is the federal listing for propylene oxide. The source, composition, concentration or test condition must match, and the exclusions in SOR/2021-25 still apply.

For federally regulated international shipments, the applicant records the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions still apply.

What does Federal E140 cover?

E140 covers propylene oxide. Use it when propylene oxide is present at 100.0 mg/kg or more by mass. Match the material, its source and any stated condition, because the name alone doesn't make it a listed waste.

CodeWhen it fits
E140The waste holds propylene oxide at 100.0 mg/kg or more by mass.
