## Is 13 05 01* hazardous?

Yes, always. 13 05 01* has an asterisk, and WM3 lists it as absolute hazardous. Waste under this code is hazardous whatever is in it, so no assessment can change that.

It moves on a [hazardous waste consignment note](https://complyonsite.com/tools/hazardous-waste-consignment-note?code=130501), not a waste transfer note. [Hazardous waste EWC codes](https://complyonsite.com/tools/ewc-code-finder?list=hazardous)
