To indicate which method you're using to provide box content information, call CreateInboundShipment or UpdateInboundShipment and set the IntendedBoxContentsSource of the InboundShipmentHeader to one of the available options: NONE, FEED, or 2D_BARCODE. The default option is NONE. If the value of IntendedBoxContentSource is NONE at the time a shipment is confirmed, the manual processing fee will be assessed when the fulfillment center receives your inventory. If FEED or 2D_BARCODE is selected but box content information is not provided, your shipment will incur a manual processing fee.
If your shipping processes do not support providing box content information, you can choose to skip this step and have Amazon manually process your shipment for a fee.
