Some carriers support the sending of dangerous goods. You can add and update product dangerous goods details via your product catalogue or over the API.
To edit dangerous goods details in the product catalogue, click on a product's SKU to view and edit its details. You will see the "Dangerous Goods" section. Here you can enter details regarding the dangerous goods information of your product. Usage of these fields varies courier to courier, but in order for the product to be recognised as dangerous you must set the value of "Enable Dangerous Goods?" to "Yes".
Make sure that after making any changes you scroll to the bottom of the popup and click "Save".
To find out what the UN Number is for your product, the UK Gov website has a list here.
