Why Amazon FBA Shipments Get Rejected
Amazon's guidance says it may refuse, return or repackage inventory that arrives with inadequate or non-compliant packaging, at your expense, so it pays to check labels before you ship. This guide covers common label and packaging problems and how to avoid them before your next shipment.
Common label problems to check
Wrong Print Scale
Printing at 'Fit to page' or any scale other than 100% changes the printed barcode size. Scaling shrinks the bars and the white space around them, which can make the barcode harder to scan. Print at 100% (Actual size).
Low print resolution
Amazon's guidance suggests a laser printer at 300 DPI for best results, with black ink on non-reflective paper.
Visible Manufacturer Barcode
If you use an FNSKU label and the original UPC or EAN is still visible, the wrong barcode could be scanned. Amazon's guidance says to cover original barcodes so they can't be accidentally scanned. This is especially common with small items where the FNSKU label doesn't fully cover the original code.
Label Placement Errors
Labels applied over edges or on curved surfaces cause the barcode to distort when the label peels or buckles at corners. Avoid shiny packing tape over the label: it can cause glare that makes the barcode harder to scan (our own advice, not an Amazon rule). Amazon's guidance calls for black ink on non-reflective paper.
Insufficient Quiet Zone
The quiet zone is the blank white border surrounding a barcode. Leave clear white space around the barcode. Amazon's archived item-label specification called for a quiet zone of more than 0.25 in (6.4 mm) at the left and right of the barcode and more than 0.125 in (3.2 mm) above and below it. Keep product text, logos and other barcodes out of the clear area around the barcode (our own advice, not an Amazon rule). Amazon's archived item-label specification describes the quiet zone as "the clear area surrounding a bar code".
Missing box content information
2D barcode box content labels (Data Matrix, PDF417 or QR Code, per Amazon's help) are one way to provide box content information. Check the box content options Seller Central shows for your shipment. Missing or incorrect box labels can slow receiving at the fulfilment centre and may lead to fees. Check the current fees for your marketplace in Seller Central.
Quick test: Open your phone camera and point it at the printed barcode from 30cm away. Test-scan a printed label with a phone barcode app before labelling stock (our own advice). A phone scan is a quick check, not a guarantee of how Amazon's equipment will read it. Re-print at higher DPI or check your quiet zones.
The 5-Minute Check Before You Seal the Box
Run through this every time before a shipment leaves your warehouse. It covers the label problems in this guide before the box is sealed.
Shipment Rejection — Common Questions
Check the shipment's status and any problem notices in Seller Central, and follow the steps Amazon gives there. You'll receive a notification. Amazon's guidance (US) says it may refuse, return, or repackage products that arrive with inadequate or non-compliant packaging, at your expense. Act on any problem notice in Seller Central promptly (our own advice).
Amazon's guidance (US) says it may refuse, return, or repackage products that arrive with inadequate or non-compliant packaging at your expense. Fees vary by marketplace and change over time, so check the current figures in Seller Central.
Yes, in most cases. Check the shipment's status and any problem notices in Seller Central, and follow the steps Amazon gives there. If the items are at the FC, you may need to request a removal order, re-label, and create a new shipment. For future shipments, use our barcode generator, check whether you need an FNSKU or UPC, and run a pre-shipment audit before sealing the boxes.
Not necessarily. 2D barcode box content labels (Data Matrix, PDF417 or QR Code, per Amazon's help) are one way to provide box content information for an inbound shipment. Check which box content options Seller Central offers for your shipment. The label carries the FBA shipment ID, each item's ID (such as FNSKU, ASIN, UPC, EAN or ISBN) and quantity, and expiry dates where they apply. Our free 2D box content label generator makes them, one per carton.
