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.
Dangerous goods also refer to consumer products such as laptops, smartphones, household cleaners, spray paints, and cosmetics. You can find a list of products that may be regulated as dangerous goods at the FBA Dangerous Goods Program.
Amazon will not allow hazmat items to be combined with non-hazmat items in the same shipment, so they will return that error when the shipment items are incompatible.
If you are not sure about the hazmat status of any item, you should follow the instructions in the FBA Dangerous Goods Program.
