ComplyOnSiteIs Federal E021 hazardous waste?
Yes, if the listing and federal definition apply. E021 is the federal listing for ammonium bisulphite. The source, composition, concentration or test condition on record must match, and the exclusions in SOR/2021-25 still apply.
On a federally regulated international shipment, the applicant records the classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions apply.
What does Federal E021 cover?
E021 covers ammonium bisulphite. Use it when ammonium bisulphite is present at >= 100.0 mg/kg by mass. The material, its source and any stated composition, concentration, test or use condition must match, because the name alone doesn't make the listing.
