Amazon Rejected My Stock: Emergency FBA Labelling and What to Do When Your Label Is Not Accepted by Amazon

FBA prep workstation with barcode printer, scanner, labelled boxes and preparation checklist

You have opened Seller Central and seen a shipment problem. Perhaps you are thinking: “Amazon rejected my stock.” Or your warning says “my label is not accepted by Amazon.”

Do not panic. In many cases, the stock is fixable. The problem is usually a barcode, label, packaging, product information or shipping-carton issue. The sooner you identify the exact reason, the sooner you can correct the goods and send them into the UK FBA network.

This guide explains what to do if Amazon reject my stock, how to fix a label that is not accepted by Amazon, and when to use emergency Amazon FBA labelling or a UK prep partner.

Amazon rejected my stock. What does that mean?

When Amazon rejects or flags your stock, it normally means the inventory does not meet one or more FBA receiving requirements. It does not always mean the product itself is unsafe or unsellable.

Common reasons include:

  • The FNSKU barcode is missing, wrong or cannot be scanned.
  • The manufacturer barcode, such as an EAN or UPC, is still visible when an Amazon barcode should be used.
  • The label has been placed over a corner, curve, seam or edge.
  • The label is inside a polybag instead of being visible on the outside.
  • The barcode was printed with a smudged or low-quality inkjet printer.
  • The FNSKU belongs to a different ASIN, SKU, product variation or condition.
  • The product needs a polybag, seal, bubble wrap or suffocation warning but has not been prepared correctly.
  • The product has a missing, unreadable or expired best-before, use-by or expiry date.
  • The shipping carton has incorrect box labels, weight, dimensions or packaging.
  • A case pack or pallet has been labelled incorrectly.

Amazon’s UK barcode requirements state that every item requiring an Amazon barcode must have the correct, readable barcode. Amazon may also charge for unplanned preparation, return the stock, dispose of it or restrict future shipments if requirements are not followed.

A rejection can also lead to FBA stranded stock. This happens when inventory is held but cannot be sold or correctly linked to an active listing. It is important to resolve both the physical preparation problem and any listing or shipment issue shown in Seller Central.

What to do if Amazon rejects my stock

If you are searching what to do if Amazon rejects my stock, follow this emergency checklist.

1. Check the notification in Seller Central

Open the relevant shipment, Shipping Queue, Fix stranded inventory page or Inbound Performance Dashboard. Read the exact notification rather than relying only on the headline.

You may see messages such as:

  • Barcode cannot be scanned
  • Unit mislabelled
  • Barcode missing
  • Unit preparation error
  • Shipment label problem
  • Product restricted or missing required information

2. Identify the exact reason code

Write down the affected shipment ID, SKU, ASIN, FNSKU, quantity and reason code. If only one product is affected, do not assume every item in the shipment has the same problem.

Also check that the label matches the exact product variation and condition. A label for a blue product cannot be used on the red variation, even if the packaging looks similar.

3. Do not send the same shipment again

Do not simply print the same labels and re-send the boxes. If the issue is not corrected, Amazon may reject the shipment again and you may pay further carrier, removal or preparation costs.

4. Decide where the stock should go

If the goods are still with your supplier or carrier, arrange a return or redirect where this is possible. If the shipment has not reached Amazon, contact the carrier quickly.

If Amazon already has the inventory, follow the available removal, return or relabelling instructions in Seller Central. Do not assume Amazon will correct every problem automatically.

5. Fix the preparation problem

Check the physical units, not just the paperwork. You may need to:

  • Print new FNSKU labels.
  • Cover other visible barcodes.
  • Rebag or reseal products.
  • Add a suffocation warning.
  • Replace damaged labels.
  • Correct dates or product information.
  • Repack the cartons.
  • Recreate the shipment labels.

6. Re-label, inspect and re-ship

Before the goods leave your warehouse, scan sample labels and check the correct quantity against the shipment. For larger quantities, inspect every unit or use a documented quality-control process.

If you are searching what to do if Amazon reject my stock, the short answer is: stop the repeat shipment, find the precise failure, correct the goods and only then re-dispatch.

My label is not accepted by Amazon: labelling troubleshooting

If you are thinking “my label is not accepted by Amazon”, start with the barcode itself and then check its position.

Test whether the barcode scans

The label should be:

  • Black ink on a white, non-reflective surface.
  • Clear and free from smudges, folds or tears.
  • Printed at 300 DPI or higher where possible.
  • Produced at 100% scale, not enlarged or compressed.
  • Easy to scan with a handheld barcode scanner.

Amazon states that inkjet printers should not be used for Amazon barcodes. A thermal printer or suitable laser printer is safer for bulk amazon fba labelling.

Check the label placement

The label is not accepted by Amazon if it is hidden, folded or difficult to scan. Place it on a smooth, flat surface. Keep it away from corners, curves, seams and edges.

The barcode must be on the outside of any prep material, including:

  • Polybags
  • Bubble wrap
  • Boxes
  • Shrink wrap
  • Protective sleeves

Allow approximately 6 mm between the label edge and the packaging edge. Keep the required white space around the barcode clear.

Cover other barcodes

If Amazon requires an FNSKU, cover or make other visible barcodes unscannable. This may include the EAN, UPC, ISBN or another seller’s barcode.

Do not cover important safety, allergen, ingredients, legal, date or compliance information. Amazon’s barcode guidance explains the exceptions and placement rules.

Check the 12 cm polybag rule

If the opening of a polybag is over approximately 12 cm, use a clear suffocation warning in English. Amazon guidance commonly refers to an opening larger than 5 inches, which is about 12.7 cm.

The warning must be visible and must not be covered by the FNSKU label. The barcode must also remain readable from the outside of the bag. Do not put the label inside the polybag where glare, folds or plastic can prevent scanning.

Check the shipping-carton labels

Each box needs its own unique FBA box ID label. Do not photocopy or reuse a label. Place the FBA label beside the carrier label on a flat surface, away from seams, openings, corners and tape.

See Amazon’s UK shipping label requirements before creating a replacement shipment.

Emergency Amazon FBA labelling: the fastest route back to Amazon

When stock has already been rejected, a specialist fba labelling service uk can help you recover time.

A UK prep partner can receive the goods, inspect the problem and complete the required work through an emergency Amazon FBA labelling service. Depending on stock location and quantity, the process may include:

  1. Same-day or next-day goods-in booking.
  2. Photos of damaged, incorrect or missing labels.
  3. SKU and FNSKU matching.
  4. Removal or covering of incorrect barcodes.
  5. New FNSKU label application.
  6. Polybagging, sealing, warnings or re-packing.
  7. Final barcode scans and quantity checks.
  8. Re-dispatch into the UK FBA network.

Look for a provider that offers a genuine fnsku labelling service, not just a printing service. The physical inspection is important because a correctly printed label can still fail if it is placed over a seam or attached to the wrong product.

Have these details ready when you contact a prep partner:

  • Shipment ID and Amazon notification.
  • ASIN, SKU and FNSKU.
  • Quantity affected.
  • Product photographs.
  • Required prep instructions.
  • Carton dimensions and weights.
  • Delivery address and collection details.
  • Your required dispatch date.

This is also where emergency fba prep can help if the problem is larger than labelling alone.
