Federal K source codes
Spent refinery hydrotreating catalyst
Use K171 only when the waste stream and named Schedule 12 industry process both match.
ComplyOnSiteIs Federal K171 hazardous waste?
Yes, if the listing and federal definition apply. K171 lists spent refinery hydrotreating catalyst. 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 still apply.
What does Federal K171 cover?
Discarded spent hydrotreating catalyst generated during petroleum refining, including guard beds used to desulfurize feeds to other catalytic reactors, excluding inert support media. The waste form and the process that made it must both match. A similar material from another operation isn't K171.

Is spent refinery hydrotreating catalyst always Federal K171?
| Code | When it fits |
|---|---|
| K171 | Spent refinery hydrotreating catalyst from the named Schedule 12 process. |
Decide from where the material came from, how it was used, what it contains and what the tests show. Sharing a chemical or process word with the listing isn't enough. The full listed condition and any federal exclusion still decide.
