This is a service Amazon provides to ensure sellers’ inventory is being stored and shipping in accordance with Amazon’s requirements. The FBA Label Service fee is $0.30 per item for standard FBA and $0.10 per item for FBA Small and Light. Amazon will apply Amazon barcodes to your eligible items upon arrival at their fulfillment center using the product information you provide. Sellers can avoid these fees by simply printing their own barcodes and labels.
