ComplyOnSiteIs Federal L31 hazardous waste?
Yes, if the listing and federal definition apply. L31 is the federal listing for uranium. The recorded source, composition, concentration or test condition must match, and the exclusions in SOR/2021-25 still hold.
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 go with it.
What waste does Federal L31 cover?
L31 covers uranium. Use it when the Method 1311 extract result is 10.00 mg/L or more. Match the material, source and any stated composition, concentration, test or use condition. The name alone isn't enough.

Is uranium always Federal L31?
| Code | When it fits |
|---|---|
| L31 | The Method 1311 extract result is 10.00 mg/L or more. |
Pick the code from the material's real origin, use, composition and test results. A shared chemical or process word doesn't make 2 codes interchangeable. The full listed condition and any federal exclusion still rule.
