Use K142 only when the waste stream and named Schedule 12 industry process both match.
ComplyOnSiteIs Federal K142 hazardous waste?
Yes, if the listing and federal definition apply. Federal K142 is the listing for coal-coke tar storage-tank 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 K142 cover?
Residue from tar storage tanks when making coke from coal or recovering coke by-products from coal. Both the waste form and the step that made it must match, so a similar material from another operation isn't K142.
- Official wording
- Tar storage tank residues from the production of coke from coal or from the recovery of coke by-products produced from coal.

Is coal-coke tar storage-tank residue always Federal K142?
| Code | When it fits |
|---|---|
| K142 | The waste is coal-coke tar storage-tank 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.
