This page list the description of all the possible FBA errors to help you understand the issue.

Message	Description
ITEM_EXCLUDED_FROM_COMMINGLING_FOR_EXISTING_MAP	Not all products are eligible for Stickerless Commingled Inventory. Most notably in grocery, health and beauty, and media products must always be labeled. Amazon is always evaluating categories and products and may change the eligibility for products at any time. Possible solution: Add the item to the FBA Shipment in SellerCentral. After adding the item the following message may be returned (along these lines): This product is not eligible for stickerless, commingling This product requires labeling to be received at our fulfillment centers. I agree to apply labels to these products.
ITEM_WITH_NO_VALID_FC	Item has no eligible Fulfillment Center as it is hazmat (hazardous material) so you can not send to FBA.

Failed to preview package reason= PARENT_IAID	A matrix parent is included in the inbound shipment. Only matrix children can be sent. (The matrix parent SKU is not a real item)

ITEM_UNDER_HAZMAT_REVIEW	Potential Hazardous Material (Hazmat). Product under review by Amazon. The product will not be accepted until we have completed our review and determined it meets Amazon's product compliance standards. This process generally takes between 4-7 business days.

The request to CreateInboundShipment must include only items and quantities that have been previously planned through CreateInboundShipmentPlan	The temporary ID assigned to a previewed shipment expires after 48 hours.
Insufficient inventory capacity for the operation	From Amazon Seller Forums - You may have an inventory storage limit. Inventory storage limits generally apply to new FBA sellers and existing FBA sellers with slower-turning inventory. If your Amazon FBA account is configured for Unlimited storage: One of the items in the Preview have an ASIN level capacity restriction. Unfortunately, Amazon does not tell us which item is causing the error.
MISSING_DIMENSIONS	Product is missing dimensions for FBA.
EXTERNAL_ID_MAPS_MULTIPLE_IAIDS	UPC for the listing was assigned to multiple ASINs. Hence, when you are sending the shipment, the ASINs are conflicting at the back end and causing errors to the system. Can happen when an item that used to be stickerless now becomes requiring label, because the UPC associated with this ASIN used to be associated with that ASIN only, but now associated with more than one ASIN. Solution - You may need to create a new listing on Seller Central.
Shipping Status is ERROR_ESTIMATING	There's an error in the address. For example, the zip code is invalid because of a period at the end of the zip code.
