ComplyOnSiteIs Manitoba EHS91 hazardous waste?
Yes, when the Schedule B threshold is met. EHS91 is a Category 3 Provincial Waste Code. It applies when ferric ammonium oxalate reaches the Schedule B total concentration of 100 mg/kg by mass.
The 3-digit provincial waste class goes in a separate field. It doesn't replace the UN Number or Provincial Waste Code.
For regulated hazardous waste, enter EHS91 in the UN Number or Provincial Waste Code field on the Manitoba movement document. Manitoba’s registration and shipment rules still apply.
What does Manitoba EHS91 cover?
EHS91 tests waste for ferric ammonium oxalate. Measure the total concentration by mass. At 100 mg/kg or more, the waste is hazardous-waste Category 3 with code EHS91.

Is ferric ammonium oxalate always Manitoba EHS91?
| Code | When it fits |
|---|---|
| EHS91 | Total ferric ammonium oxalate is 100 mg/kg or more by mass. |
Pick the code from what the waste is made of, its test result and where it came from. Provincial registration and movement rules, federal cross-border controls and TDG classification are separate checks, and a code doesn't replace them.
