Is Federal C31 hazardous waste?

Not from this code alone. Federal C31 is one classification component for hazardous waste or hazardous recyclable material. It records a constituent or characteristic. The full evidence and the definitions and exclusions in SOR/2021-25 decide the federal status.

On a federally regulated international shipment, the applicant enters the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions apply.

What does Federal C31 cover?

Federal C31 covers azides. Use it when the material contains azides. Match the material, its source and any stated composition, concentration, test or use condition. The name alone doesn't settle it.
