FBA Label Placement Mistakes: A ₩900,000 Annual Cost Bomb!

FBA Labeling Errors: How to Avoid Over ₩900,000 in Annual Losses
Failing to follow the precise placement and principles for Amazon FBA (Fulfillment by Amazon) labels can lead to unexpected relabeling costs exceeding ₩900,000 annually. With currently strengthened policies in effect, it's crucial to familiarize yourself with the correct labeling guidelines right now to prevent unnecessary expenses and inbound delays.
As an Amazon FBA seller, you likely understand the importance of product labeling. But are you aware that seemingly minor mistakes, beyond just label 'quality' or 'specifications'—such as 'placement' or 'failure to remove unnecessary labels'—can result in hundreds of thousands, or even millions, of won in avoidable annual costs?
Amazon FBA Labeling Policy Changes and Cost Drivers
Notably, Amazon recently discontinued its in-house product preparation service (Prep Service) for US sellers. This means sellers must now perfectly prepare all products sent to FBA themselves or utilize a third-party logistics (3PL) prep center.
If products arrive at an Amazon Fulfillment Center without adhering to labeling policies, Amazon may classify them as 'defective,' apply barcode stickers themselves, and charge a fee for the service.
Previously, Amazon's labeling service cost $0.55 per item (approximately ₩750, based on 1 USD = 1360 KRW). If labeling errors occurred on 100 items per month, this would amount to a substantial additional annual cost of ₩900,000 (₩750 x 100 items x 12 months).
Furthermore, recently implemented policies require resellers to use Amazon barcodes (FNSKU) even if a manufacturer barcode is present, among other barcode requirement changes, necessitating increased vigilance.
3 Key Rules for Successful FBA Inbound Shipments
To ensure successful FBA inbound shipments, you must strictly adhere to these three core rules:
1. Only One Scannable Barcode Should Be Visible On product packaging, only one scannable barcode—either the FNSKU (Fulfillment Network Stock Keeping Unit) barcode or a manufacturer barcode (UPC/EAN/ISBN)—should be visible. If other barcodes are visible or more than one is exposed, it can confuse the scanning system, leading to inbound delays and processing errors.
2. Attach Accurately to a Flat, Scannable Surface FNSKU labels must be affixed to a flat, clean surface of the product packaging, not on curved areas or edges. Be careful not to place labels over box seams or openings, and avoid covering the barcode with clear tape or other materials that could obstruct scanning. It's recommended to leave a minimum of 0.25 inches (approximately 6.35mm) of space between the label's edge and the product packaging's edge.
3. Completely Cover Existing Barcodes When applying an FNSKU label, you must completely cover all existing manufacturer barcodes (UPC/EAN/ISBN, etc.) originally printed on the product with the FNSKU label. Do not partially cover or place it next to an existing barcode in a way that allows the scanner to read the old barcode.
The Impact of Minor Labeling Mistakes on Your Business
The impact of minor labeling mistakes on your business is greater than you might expect.
Relabeling Fees Incurred: Amazon may perform relabeling work on improperly labeled products themselves and charge a per-item fee. Historically, Amazon's labeling service cost $0.55 per item, while external prep centers typically charge in the range of $0.40 to $0.70. For large shipments, this can become a significant financial burden. Inbound Delays and Rejections: Problems with label identification can cause inbound shipments to the Fulfillment Center to be delayed or even rejected. This slows down the time it takes for inventory to become sellable, leading to lost sales opportunities. Inventory Disposal or Return: If severe labeling errors make product identification impossible, Amazon may dispose of the inventory or return it to the seller, incurring additional disposal or return fees in the process. Negative Impact on Account Health: Repeated violations of labeling policies can negatively affect your Account Health under Performance in Seller Central, and in severe cases, your selling privileges may even be suspended.
⚠️ Warning: Repeated labeling policy violations can lead to the suspension of your selling privileges.
Immediate Actions to Cut Unnecessary Costs
Take action now to cut unnecessary costs!
1. Final Check Before Printing FNSKU Labels Before printing FNSKU labels, always confirm that they precisely match the product information, that the print quality is clear, and that the barcode is not smudged or damaged. (Labels can be printed via Seller Central → Inventory → Manage FBA Inventory → Print Item Labels) 2. Mock Labeling Test Before applying labels to actual products, test them on a sample product to ensure existing barcodes are completely covered, they adhere well to flat surfaces, and there's sufficient margin. 3. Regularly Review FBA Prep Service Guides Periodically check Amazon's help pages related to FBA prep requirements and barcode requirements to stay updated on the latest policies.

Common Labeling Mistakes and Precautions
1. Failure to Completely Cover Existing Barcodes It's common for a product's manufacturer barcode (UPC/EAN) to remain partially exposed even after an FNSKU label is applied, confusing scanners. Always ensure the FNSKU label completely covers the existing barcode. 2. Confusion with Bundle Product Labeling Many sellers often misunderstand the labeling policies for bundle products, which are sold as multiple items grouped together. Recently, Amazon has tightened its policy, particularly in consumer goods categories like groceries, health, pet supplies, and baby products, to only permit bundles configured by the manufacturer. Additionally, each bundle product requires a unique UPC or product identifier; you cannot use the UPCs of individual items within the bundle. When labeling bundle products, you must thoroughly review Amazon's bundling policy. (Search for “Product Bundling Policy” in the Seller Central search bar)
