ComplyOnSiteIs Federal E137 hazardous waste?
Yes, if the listing and federal definition apply. Federal E137 is the federal listing for propionic acid. 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 E137 cover?
E137 covers propionic acid. Use it when propionic acid 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 acid always Federal E137?
| Code | When it fits |
|---|---|
| E137 | The waste holds propionic acid 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.
