Solid precious-metal residue with trace cyanide, holding only traces of inorganic cyanides. Not hazardous.

Is Basel B1140 hazardous waste?

Not from the code alone. Basel B1140 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 B1140 cover?

Covers solid residue that holds precious metals and only trace amounts of inorganic cyanide. List B status holds only while the waste has no Annex III hazardous characteristic.
