Hi @Seller_Dvlul6DS3PVZf,

Dangerous goods (also called hazmat) are substances or materials that may pose a risk during storing, handling, or transporting because they contain flammable, pressurized, corrosive, or otherwise harmful substances. To prevent potential health and safety risks, Amazon gathers dangerous goods information related to any products sold on Amazon. For more information, go to Dangerous goods required information and documentation (hazmat).

If the items are considered dangerous goods you will have to check that they are if prompted.

Best,

Dominic
