Mercury residue, the liquid metal from lamps & thermometers, in Quebec's group of inorganic solids & sludge. It must be named.

Is Quebec E23 hazardous waste?

Not from the code alone. E23 is a Quebec residual hazardous-material category. The material must meet the regulatory definition first, and still meet it after the exclusions and quantity rules are applied.

Record E23 as the Quebec MDR category. For dangerous goods in transport, show the MDR code apart from the TDG shipping description. The category doesn't replace the UN number, shipping name, class or packing group.

A regulated interprovincial, import, export or transit movement may also need the federal movement document. Each document has its own scope, so the Quebec category alone doesn't settle the paperwork.
