Basel List B codes
Non-hazardous solution between pH 2 and 11.5
Use B2120 for non-hazardous solution between pH 2 and 11.5 as a Basel List B waste without an Annex III hazard.
ComplyOnSiteIs Basel B2120 hazardous waste?
Not from the code alone. Basel B2120 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 B2120 cover?
Covers discarded acidic or basic solutions with a pH above 2 and below 11.5, as long as they are neither corrosive nor otherwise hazardous. Compare A4090.
