Is Basel Y11 hazardous waste?

Not from the code alone. Basel Y11 is a Basel waste stream or constituent used in the IWIC. The code describes the material. Its hazards, the other classification parts, and the definitions and exclusions in SOR/2021-25 decide its federal status in Canada.

On federally regulated international shipments, 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 Basel Y11 cover?

Tarry residue from refining, distillation or any pyrolytic treatment. Its Canadian movement status needs a separate assessment under SOR/2021-25, including the destination and intended operation.
