Some carriers support the sending of dangerous goods.
If you navigate to your product catalogue and click into a product, you can see the two fields we currently support at the bottom:
Product Volume and UN Number. Once entered, you can close the pop-up and these fields will save.
To find out what the UN Number is for your product, the UK Gov website has a list here.
Our API supports these fields, please consult the documentation for more.
If you have any questions, please feel free to reach out to support at support@shiptheory.com.
