  • Federal E codes

    Propionic anhydride

Use E138 when propionic anhydride is present at >= 100.0 mg/kg by mass.

Waste holding propionic anhydride at 100 mg/kg or more by mass. It is corrosive, reacts with water and is used in plastics & drugs.

Is Federal E138 hazardous waste?

Yes, if the listing and federal definition apply. Federal E138 is the federal listing for propionic anhydride. 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 E138 cover?

E138 covers propionic anhydride. Use it when propionic anhydride 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.

Is propionic anhydride always Federal E138?

CodeWhen it fits
E138The waste holds propionic anhydride at 100.0 mg/kg or more by mass.

Decide from where the material came from, how it was used, what it contains and the test results. A shared chemical or process word doesn't make the codes interchangeable. The full listed condition and any federal exclusion still decide.
