Amazon charges monthly inventory storage fees for the space your inventory occupies in fulfillment centers. Monthly storage fees are calculated on your daily average volume in cubic feet, based on the size of a unit that is properly packaged and ready to ship in accordance with FBA policies and requirements. Fees vary based on product size and time of year. You may have inventory that is classified as dangerous goods, which have fees that are assessed using a different rate card (see below). To determine if your inventory is considered dangerous goods, review the Dangerous Goods Identification Guide.
Program specifics: The details, calculations, or rates for this fee vary if enrolled in the following programs. Visit the program-specific Help page for more information.
