Is Basel A3120 hazardous waste?

Normally yes. A3120 is on Basel List A, so the material is presumed hazardous unless the evidence shows it has no Annex III hazardous characteristic. The exact description and any stated exclusions still have to match.

For international shipments under the federal rules, the applicant enters the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions still apply.

Is shredder light fraction Basel A3120 or another code?
