Inbound Performance Summary

When you comply with Fulfillment by Amazon's Packaging and prep requirements and Shipping and routing requirements, and make sure that your carriers and suppliers do as well, it enables efficient and accurate receipt and storage of your inventory at the fulfillment center.

When we cannot receive products at the fulfillment center due to any of the problems detailed on this page, we perform unplanned services to successfully process your inventory, at your cost.

We provide shipment-level details of any problems with your shipments in the following Seller Central locations:

Additional coaching or product prep requires resources. For repeated problems in the same problem group, Amazon will escalate your coaching level (Standard, Elevated, Critical).

For detailed coaching-level escalations, and their corresponding corrective actions by problem type, see the Unplanned services help page.

Note: Amazon escalates your inbound performance issues by Problem group.

Stacking

  • Stack boxes on your pallets to ensure that they can be properly unloaded and received.
  • Place heavier boxes on the bottom so they do not damage boxes containing lighter products beneath them.
  • Stacked pallets should be able to stand on their own without support.

Weights and dimensions

  • Single pallets must not be taller than 180 cm, including the height of the pallet
  • Amazon only accept the following types of pallet:

Problem group: Label missing - box related

Problem type Problem description How to avoid the problem
Shipment ID was not included or is unscannable on shipping boxes

One or more of the boxes in your shipment did not have an FBA shipment ID label, or the label could not be scanned.

Each box you send to a fulfillment center must have a shipment ID label. Make sure the labels are uncovered, fully visible, and scannable before sending your shipment.

Label requirements

  • Print the full set of labels. Because each label is unique, do not photocopy, reuse, or modify labels for use on additional boxes.
  • Each box in the shipment must have its own FBA shipment ID label. In addition, each pallet you send needs four labels, one in the top center of each side.
  • These labels must be printed from your Shipping Queue. As an alternative, you can create your own labels, but they must match the Amazon MWS Fulfillment API Developer Guide specifications for creating your own shipping labels.
  • If you are shipping multiple case packs in a larger box, apply the unique shipment ID label on the primary box. You don't need to apply labels to the individual case packs inside the larger box.
  • If your shipment is on pallets, each box on the pallet must have its own shipment ID label. This is in addition to the four labels in the top center of each side of the pallet.

Label dimensions and placement

  • Labels must respect the supported measure
  • Both the FBA shipment ID label and the carrier label (UPS, FedEx, or other) should be placed on a flat surface of the box. Do not place labels on a seam or an opening on the box, or over edges or corners because the labels could be damaged when the box is opened.
  • Both labels must remain uncovered and fully visible.

For more information, go to Shipment label requirements.

Problem group: Label missing - product related

Note: The table below provides information about labelling issues.
Tip: If you do not want to label your products yourself, Amazon will apply them for you, for a per-unit fee. For more information, visit FBA Label Service.
Problem type Problem description How to avoid the problem
Amazon barcode missing One or more of the products in your shipment arrived without the required scannable Amazon barcode, also known as an X00 label or FNSKU. The Amazon barcode is an identifier that fulfillment centers use to identify individual offers for a specific ASIN.
  • If you chose to use an Amazon barcode when you created a listing for a product to be fulfilled by Amazon, you must put the correct X00 label on the product. You can print Amazon barcodes from the Label Products page when you create a shipment or at any time from the Manage Inventory page.
  • Make sure the label title matches the corresponding unit, and label your units one at a time.
  • Cover the entire original manufacturer barcode with your X00 label, and make sure the barcode is visible so it can be scanned at the fulfillment center.
  • For more information, see Use an Amazon barcode to track inventory.

Manufacturer barcode missing One or more of the products in your shipment arrived at the fulfillment center without the required scannable manufacturer barcode (GCID, UPC, EAN, JAN, or ISBN). Amazon will always use the manufacturer barcode to track your inventory throughout the fulfillment process, unless you change your barcode setting.
  • Make sure your products have a physical barcode (GCID, UPC, EAN, JAN, or ISBN) that is visible so it can be scanned at the fulfillment center.
  • If an ASIN qualifies for tracking by the manufacturer barcode but doesn't have a physical barcode, you can print labels by going to the Inventory Amazon Fulfills page and selecting Print item labels from the Action on drop-down menu.
  • Make sure the label title matches the corresponding unit, and label your units one at a time.
  • For more information, see Using the manufacturer barcode to track inventory.

Suffocation warning missing Suffocation warning labels are required for poly bags with an opening that is 5 inches or larger (measured when flat).

Suffocation warnings must be printed in a legible font size for the size of the bag and placed in a prominent location.

Example warning

WARNING: To avoid danger of suffocation, keep this plastic bag away from babies and children. Do not use this bag in cribs, beds, carriages, or play pens. This bag is not a toy.

Problem group: Incorrect label - product related

Problem type Problem description How to avoid the problem
Unit mislabeled The item arrived with a barcode that does not match the physical product.

Ensure that the right label is affixed to the right product.

  • Label your products one at a time.
  • Make sure the label title matches the corresponding product.

For more information, see:

Barcode cannot be scanned One or products in your shipment had a barcode that was smudged or smeared and could not be scanned at the fulfillment center.

Verify that your products have a physical, scannable barcode (UPC, EAN, JAN, ISBN, etc.).

Label placement and size

  • Cover any original barcodes. When using an X00 label, cover the entire, original manufacturer barcode with your label. No other barcodes should be visible.
  • Use the right label and size and type All Amazon barcodes must be printed in black ink on white, non-reflective labels with removable adhesive. Dimensions must be between 25.4mm x 50.8mm and 50.8mm x 76.2mm (1” x 2" and 2” x 3")
  • Ensure a sufficient white space around the Amazon barcode and related text (6.4mm / 0.25" on the sides and 3.2mm/ 0.125" on the top and bottom)

Printer requirements

  • Use a laser printer for your labels. Inkjet printers are more susceptible to smearing and blurry images.
  • Clean your printer. Many labeling errors are caused by dirty printer heads.

For more information, see:

Barcode is not accessible by scanner Due to poor label placement, or prep such as bubble wrap, your barcode is not scannable.

Make sure that the labels lay flat and do not fold over edges. Please ensure a minimum quiet zone before and after the barcode (6.4mm / 0.25" on the sides and 3.2mm/ 0.125" on the top and bottom)

  • Cover all other visible barcodes except for serial number barcodes that uniquely identify the item (for example, IMEI barcodes on mobile phone packaging).
  • You place the barcode on the outside of any prep materials.
  • You do not place the barcode on a curve or corner of the package.
  • Make sure that each item in a case pack has an Amazon barcode and that any barcodes on the case have been removed.

Problem group: Expiration problems

Problem type Problem description How to avoid the problem
Expiration issue Your expiration-dated inventory must be prepped so the expiration date is visible during the receiving process.

Problem group: Inaccurate box count

Amazon requires accurate box content information for each box sent to a fulfillment center. This information allows the fulfillment center to receive your shipment more quickly and make your inventory available for sale sooner.
