## Is 17 06 03* hazardous?

Yes, unless an assessment shows it isn’t. 17 06 03* has an asterisk, and WM3 lists it as mirror hazardous: the hazardous side of a choice between codes, decided by [assessing the waste under WM3](https://assets.publishing.service.gov.uk/media/6152d0b78fa8f5610b9c222b/Waste_classification_technical_guidance_WM3.pdf).

If it isn’t hazardous: [17 06 04](https://complyonsite.com/tools/ewc-code-finder?code=17-06-04). If you can’t find out what’s in it, it stays 17 06 03*.

As hazardous waste it moves on a [hazardous waste consignment note](https://complyonsite.com/tools/hazardous-waste-consignment-note?code=170603), not a waste transfer note. [Hazardous waste EWC codes](https://complyonsite.com/tools/ewc-code-finder?list=hazardous)
