ComplyOnSiteIs Basel B3100 hazardous waste?
Not from the code alone. Basel B3100 is on Basel List B, so material matching it is normally not hazardous under the Convention. It becomes hazardous if Annex I constituents give it an Annex III hazardous characteristic. SOR/2021-25 and its exclusions decide Canadian federal control.
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 Basel B3100 cover?
Covers leather dust, ash, sludge and flour that contain neither hexavalent chromium compounds nor biocides. Compare A3090. List B treatment holds only while the waste has no Annex III hazardous characteristic.
