ComplyOnSiteIs Federal E148 hazardous waste?
Yes, if the listing and federal definition apply. Federal E148 is the federal listing for sodium hydrosulphide. The source, composition, concentration or test condition must match, and the exclusions in SOR/2021-25 still apply.
For federally regulated international shipments, the applicant records the waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions still apply.
What does Federal E148 cover?
E148 covers sodium hydrosulphide. Use it when sodium hydrosulphide is present at 100.0 mg/kg or more by mass. Match the material, its source and any stated condition, because the name alone doesn't make it a listed waste.
