Use K141 only when the waste stream and named Schedule 12 industry process both match.
ComplyOnSiteIs Federal K141 hazardous waste?
Yes, if the listing and federal definition apply. Federal K141 is the listing for coal-coke tar-recovery process residue. 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 waste classification in the waste-line details of the federal notification in CNMTS. The movement rules and exclusions apply.
What does Federal K141 cover?
Residue from recovering coal tar, including collecting sump residue, when making coke from coal and recovering coke by-products. Waste listed as K087 is excluded. Both the waste form and the step that made it must match, so a similar material from another operation isn't K141.
- Official wording
- Process residues from the recovery of coal tar, including collecting sump residues from the production of coke from coal and the recovery of coke by-products produced from coal, excluding waste listed as K087.

Is coal-coke tar-recovery process residue always Federal K141?
| Code | When it fits |
|---|---|
| K141 | The waste is coal-coke tar-recovery process residue from the named Schedule 12 process. |
Decide from where the material came from, how it was used, what it holds and the test results. A shared chemical or process word doesn't make codes interchangeable. The full listed condition and any federal exclusion still apply.
