Basel List B codes
Stabilized high-iron zinc slag
Use B1220 for stabilized high-iron zinc slag as a Basel List B waste without an Annex III hazard.
ComplyOnSiteIs Basel B1220 hazardous waste?
Not from the code alone. Basel B1220 is on Basel List B, so material that matches it is normally outside the Convention's hazardous definition. That changes if Annex I constituents give it an Annex III hazardous characteristic. SOR/2021-25, including its exclusions, decides Canadian federal control.
On a federally regulated international shipment, the applicant enters the waste classification in the waste line of the federal notification in CNMTS. The movement rules and exclusions still apply.
What does Basel B1220 cover?
Covers zinc-production slag that is chemically stabilized, holds more than 20% iron and is processed to industrial specifications such as DIN 4301. It is used mainly for construction.
