What is hazmat on Amazon?

Products classed as hazardous materials, with extra FBA rules and delays.

Hazmat (hazardous materials, or "dangerous goods") covers products containing batteries, aerosols, flammables, magnets and similar - many of them perfectly ordinary retail items like perfume, power tools or laptops. FBA handles hazmat through a separate programme with its own approval, limits and slower check-in.

For a sourcing decision hazmat is not a no - it is a delay-and-capacity question you want to know about before buying, not when your shipment is refused. That is why results flag likely hazmat products up front.
