The specifications for each method's Amazon labeling are described in this article
Depending on the ultimate delivery method you use to deliver to Amazon, different labeling requirements apply to Amazon sellers.Labels FNSKU
To distinguish a product belonging exclusively to a seller, Amazon gives it an FNSKU (Fulfillment Network SKU).
Every product sold on Amazon must have an FNSKU label, but you can register with Amazon to make sure your manufacturer barcode satisfies this requirement.
Unless you register the unit label as the FNSKU, unit labels are the labels on your actual goods and are not Amazon labels. Each product needs to have an FNSKU label attached to it.
Carton Labels for FBA
You can generate FBA (Fulfillment by Amazon) carton labels by completing the online form in your Amazon Seller Central account.
Send the FBA carton labels to your supplier for labeling at the origin to guarantee smooth shipping.
Your package will have multiple FBA IDs if it has been divided across several fulfillment centers.
Make sure your supplier labels each carton with the appropriate FBA label since each FBA ID will have a unique FBA label.
The containers MUST be marked with the Amazon SKU if your supplier does not apply Amazon FBA carton labels at the origin.
When sending FCL (full container load) to Amazon, labels must be placed at the origin; otherwise, the shipment will need to be transloaded.
Pallet Labels for LTL
Your shipment must be palletized before it can be delivered to Amazon if you're utilizing Beeontrade LTL or Amazon LTL.
At our warehouse, pallet labels will be applied. For your operations staff to download, print, and apply the pallet labels after the shipment has been palletized at the warehouse, Beeontrade asks for restricted access to your Amazon Seller Central account.
Your invoice will include a Warehouse Value Add charge for the cost of palletization.
FCL Options for Packing
You have the option of palletizing or floor-loading your cargo if you are delivering a complete container to Amazon.
Pallet labels must be used when the shipment is palletized at the point of origin if you decide to palletize.
Only if the master cartons are labeled with the Amazon SKU or product name as specified in Amazon Seller Central may FBA labels be applied at a Beeontrade warehouse.
You will be expected to assume responsibility if the cartons are not tagged and you ask for labeling services at a Beeontrade warehouse.
