    Ammonium thiosulphate

Federal E code for ammonium thiosulphate, a salt used in film fixing & liquid fertilizer. Listed at 100 mg/kg by mass or more.

Is Federal E031 hazardous waste?

Yes, if the listing and federal definition apply. E031 is the federal listing for ammonium thiosulphate. 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 E031 cover?

E031 covers ammonium thiosulphate. Use it when ammonium thiosulphate 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.
