This article addresses error messages that one may encounter when listing FBA. 

NOT_IN_PRODUCT_CATALOG

This issue occurs when Amazon.com’s information is not in sync with the information provided by Amazon’s MWS API. This is outside of our control and usually remedies itself the next time Amazon initiates an API sync.

If you are still having this issue after 24 hours, contact Seller Central Support and tell them that the item is not being found when searched in their MWS API. They should provide a window for when the problem will be solved.

ITEM_EXCLUDED_FROM_COMMINGLING_FOR_EXISTING_MAP    

Not all products are eligible for Stickerless Commingled Inventory. Products in grocery, health and beauty, and media must always be labeled. Amazon is always evaluating categories and products and may change product eligibility at any time.

Solution (possible): Add the item to the FBA Shipment in Seller Central. After adding the item, some version of the following message may appear: 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 because it is hazmat (hazardous material). You cannot send it to FBA.

NO_EXTERNAL_IDENTIFIER_FOR_EXISTING_MAP    

The product is missing a UPC on Seller Central.

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).

UNKNOWN_SKU

This SKU is not in your FBA Catalog.

Solution: Change the product to Fulfilled by Amazon. Launch the product to Amazon, wait several minutes, then retrieve the FNSKU by executing the action Get FNSKU.

ITEM_UNDER_HAZMAT_REVIEW    

Potential Hazardous Material (Hazmat). Product under review by Amazon.

You must include a valid ShipmentId with a call to the CreateInboundShipment operation. Get ShipmentId values by calling the CreateInboundShipmentPlan operation. 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 in 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 has an ASIN level capacity restriction. Unfortunately,  Amazon does not tell us which item is causing the error.

MISSING_DIMENSIONS

Missing Dimensions; How do I add dimensions?

EXTERNAL_ID_MAPS_MULTIPLE_IAIDS

UPC for the listing was assigned to multiple ASINs. When you send the shipment, the ASINs conflict in the back end and cause errors in the system. This can happen when an item that used to be stickerless now becomes requiring label. That’s because the UPC associated with this ASIN used to be associated with that ASIN only, but is now associated  with more than one ASIN.

Solution: You may have 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.

Seller has not accepted Amazon’s Partnered Carrier Program terms and conditions. Seller should accept Amazon’s Partnered Carrier Program terms and conditions on Seller Central.

CannotConfirmTransportContent

The Amazon-partnered shipment request is ineligible for confirmation. Check if the shipment is already confirmed.

CannotEstimateTransportContent

CannotVoidTransportContent

The Amazon-partnered shipment request can no longer be voided.

CarrierContractNotSigned

Seller has not accepted the carrier’s terms and conditions. Seller should accept the carrier’s existing or revised terms and conditions on Seller Central.

CarrierInvalidForMarketplace

InvalidCountrySubdivisionCode

The specified ShipToCountrySubdivisionCode is invalid. Ensure that the  ShipToCountrySubdivisionCode value is for a country subdivision that contains an Amazon fulfillment center where the seller is registered.

MissingCarrierType

No CarrierName value was specified. Specify a valid CarrierName value.

NoPackagesOrPallets

No package information (for Small Parcel shipments) or pallet information (for Less Than Truckload/Full Truckload (LTL/FTL) shipments) was specified. Specify this information using either the PackageList or the PalletListparameter of the PutTransportContent operation.

TransportContentNotFound

UnknownCarrierType

No carrier was found that matched the specified CarrierName value. Specify a valid CarrierName value.

Quantity is not divisible by QuantityInCase for SellerSKU: xxxxxxxx

The Qty to Ship is not divisible by the Qty Per Case. For example, Qty to Ship = 1 and Qty Per Case = 50 is incorrect, because 1 is not divisible as a whole number by 50. Qty to ship refers to the Qty of Units you are shipping.

Unexpected error occurred 500

An HTTP 500 error isn’t usually an Amazon server issue. the problem should be resolved by itself in 30 minutes to an hour.

EXP_DATED_ITEM_HAS_EXISTING_STICKERLESS_MAP

The merchant’s SKU is marked as a commingled product, but it is not commingleable. Amazon may change that error message to: Expiry-dated or lot-controlled product cannot be commingled. Please create a new listing for the same ASIN but a different SKU.

LABEL_PREP_OWNER_INCOMPATIBILITY_ERROR

Can occur when AMAZON_LABEL_ONLY is sent. Amazon is returning a message that they do not have enough information about the product to label the product themselves. Example: the product does not have a UPC.

Solution: Add the product information or label items yourself. Use the Seller Label option

Seller is blocked by the AndonCordManager.

This is most likely an FBA compliance issue, not a technical or code issue. Check your account’s status and speak to an Amazon representative if necessary. How do I resolve the AndonCordManager error message I get while listing?

EXTERNAL_ID_MAPS_MULTIPLE_IAIDS_FOR_EXISTING_MAP

The item has a new FNSKU and can longer be posted under the existing one.
