A2020 Basel waste code Wet fluoride waste from industry, as liquid or sludge.

Is Basel A2020 hazardous waste?

Normally yes. Basel A2020 is a List A description, so the waste is presumed hazardous unless evidence shows it has none of the Annex III hazardous characteristics. The description and any stated exclusions must still match.

For federally regulated international shipments, 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 inorganic fluoride waste always Basel A2020?

Pick the entry whose description and conditions match the material. The code classifies the waste. It doesn't decide whether SOR/2021-25 applies, whether an exclusion fits, what the destination country requires or what operation is intended.
