Amazon FBA: Packaging, Labeling, and Pallet Specification Guide
Introduction
It’s not as simple as putting things in a box and giving them to a carrier to ship to Amazon FBA. Amazon’s fulfillment facilities are quite automated, and the packing, labels, and pallets you employ must meet tight standards so that their systems can quickly collect, store, and send your items.
If you do it right, compliance packing and labeling will speed up check-in processes, lower the number of damaged items, and help you avoid expensive delays or chargebacks. If you don’t do it right, your shipment could be turned away, have to be fixed at your expense, or even be destroyed.
This tutorial explains the most important parts of Amazon FBA packing, labeling, and pallet criteria in simple, easy-to-understand language. You will learn what Amazon wants at each step, how to plan your packaging, and how to collaborate with skilled logistics partners to lower your risk, especially if you are shipping from China or other places where goods are made.
How Amazon FBA Receives and Handles Your Inventory
Before diving into the details, it helps to understand what happens when your shipment reaches an Amazon fulfillment center.
Your cartons arrive on a truck, are unloaded, and scanned against your shipment ID. Each box is then opened and the units inside are scanned individually. If your packaging and labels are correct, units are quickly associated with your seller account and moved to storage bins. When a customer orders your product, Amazon’s systems find the closest units, pick them from storage, and pack them into outbound parcels.
The key point is that Amazon’s process is built around barcodes and standardization. Every mis-labeled unit, poorly packaged product, or inaccurately described carton forces someone to stop and fix the problem manually. That is why Amazon’s FBA packaging and pallet rules can feel strict: they are designed to eliminate manual exceptions.
FBA Packaging Requirements for Individual Units
Basic protection requirements
Every item you send to FBA must be “retail-ready” and able to handle being moved about in a busy warehouse. That means the packaging for your unit should keep the goods safe during:
- Transport over long distances, especially if you ship to other countries.
- Putting things on pallets, stacking them, and storing them.
- Putting things back into Amazon packages for shipping.
Products that are fragile need padding on the inside or retail packaging that won’t break under weight. To keep liquids from leaking, they need to be sealed and sometimes put in bags or wrapped. To keep dirt and moisture out, textiles should be put in bags.
Amazon thinks that a single device dropped from waist height won’t break or leak. If clients are already complaining about breakage, then means your main package isn’t strong enough to handle FBA.
Poly bags, shrink wrap, and bubble wrap
A lot of things need more work than just being put in their retail packaging. Amazon usually wants any things that are loose, uneven, or made up of more than one piece to be kept together as one unit. Some common choices are:
- Poly bags that say they may suffocate textiles, plush toys, or a lot of small pieces.
- Shrink wrap for bundles or multi-packs so that they can’t be readily taken apart.
- Use bubble wrap to protect fragile things like glass, ceramics, or electronics that are sensitive.
When you use poly bags, make sure to check the thickness, clarity, and closure of the bags. Not only loosely folding the bags, they need to be sealed. If the bag opening is big enough to be dangerous, it usually needs to have a suffocation warning in the right languages and letter sizes.
Multi-packs and bundles
If you sell a multi-pack that you made, such “3-Pack of XYZ Shampoo,” instead of the manufacturer, Amazon needs to treat it as one product. That means the packaging needs to be apparent that it is a set and that it shouldn’t be broken up.
One easy way to do this is to put the things together and print a note on the outside that says, “Sold as set—do not separate.” Not one FNSKU barcode for each item inside a bundle or multi-pack.
Carton and Master Carton Specifications
The next step after getting the unit packing right is to get the master carton right. This is the box that holds all of your units. Amazon has standards for both the physical constraints of each box and the information that is printed or labeled on it.
Carton size and weight
Most sellers plan around conservative rules to prevent difficulties, even though specific limits can vary by platform and product type. Most people inside the company follow the rule of thumb that normal boxes should weigh no more than 50 pounds (approximately 23 kg), unless the box has one big, heavy item that can’t be broken up. It’s hard to manage really heavy boxes, and they are more likely to get damaged or turned down.
The box itself should be strong enough to stack, and for heavier items, double-wall corrugated cardboard is usually used. Don’t use boxes that have outdated barcodes or logos from other companies again. If you have to use them again, make sure that all of the old labels are totally covered.
Inner packing and void fill
You need to keep the units from moving and getting squished inside the box. Use the right void fill, like kraft paper, air cushions, or foam. Filling a carton too much such that the top bulges is just as bad as not filling it enough. Both make pallets unstable and raise the chance of damage.
Try to make the way you package everything within your boxes the same every time. This helps spread the weight evenly and keeps units from crushing each other.
Carton labeling overview
Every FBA box must have a clear label that says:
- The package ID and FBA shipment ID (made in Amazon Seller Central).
- Labels on boxes that can be scanned and match the shipment plan.
- If the box is too heavy for your marketplace, it should have warnings like “Team lift” or “Heavy.”
It is also a good idea to publish the contents of the carton (SKU and quantity) in simple language. Amazon’s systems don’t need this for receiving, but it helps you and your logistics partner check the shipment quickly.
Here is an easy way to organize your internal carton checklist:
| Item | Recommended Practice |
|---|---|
| Carton weight | Keep under typical FBA limit for your marketplace, unless a single heavy unit |
| Carton size | No oversized dimensions without matching product type |
| Carton material | Strong corrugated cardboard, no fragile recycled thin boxes |
| Inner cushioning | Sufficient void fill, no excessive empty space |
| Old labels/markings | Fully removed or covered |
| FBA box label | Printed clearly and applied on a flat surface |
| “Heavy” or “Team lift” label | Added when required by local safety rules |
Labeling Requirements: Barcodes, Box Labels, and Warning Labels
Labeling is the most important part of FBA compliance. If your labels are missing, hard to read, or in the wrong place, even well-packed boxes can be turned down or delayed.
Product-level barcodes
Every FBA unit must have a unique barcode that can be scanned. The most prevalent choices are:
- Barcodes from the manufacturer (UPC, EAN, ISBN).
- Amazon FNSKU labels are unique to your seller account.
A lot of sellers put FNSKU codes on all of their items, especially when they share the same manufacturer barcode with other sellers or wish to keep their inventory separate from others.
Your barcode label needs to:
- Print at a high resolution, at least 300 dpi.
- Use black ink on a white background that is dark enough.
- Put it on a level surface that is easy to scan.
- Do not put it over seams, curves, or corners.
If your product already has a manufacturer barcode and you’re using a FNSKU instead, you should hide or take off the old barcode so that there is no misunderstanding when scanning.
Carton and shipment labels
Seller Central makes box labels for FBA inbound shipments that have shipment IDs and other information on how to get there. You need to include a different box label on each carton in your shipment.
The best way to do this is to put these labels on at least two sides of the box that are next to each other, but not on seams or corners. This lets warehouse workers scan the box from different angles without having to move it around too much.
You will also need pallet labels (also made in Seller Central) that show the pallet is part of the shipment if it is palletized. People commonly put these pallet labels on all four sides of the pallet, at eye level.
Many salespeople think of labels in three layers to help them stay organized in their heads:
| Label Type | Applied To | Purpose |
|---|---|---|
| Unit barcode | Individual product | Identify each sellable unit in inventory |
| Carton box label | Shipping carton | Match box to specific FBA shipment and box ID |
| Pallet label | Palletized shipment | Identify pallet within shipment for receiving |
Warning, hazard, and compliance labels
Some products need extra labels, like:
- Warnings about suffocation for things in poly bags.
- Warnings on the dangers of lithium batteries and other technologies.
- “Fragile,” “This side up,” or “Do not stack” messages where they are needed.
These aren’t just Amazon’s preferences; a lot of them are required by law or by the carrier. If your product has batteries, liquids, aerosols, or other parts that could be dangerous, be sure that all of the labeling follows transportation rules by working closely with your logistics provider and carrier.
Pallet Specifications for Amazon FBA
When you send a lot of things or by ocean freight, your cartons are normally put on pallets before they get to Amazon. Pallet specs are important because they determine how readily Amazon can move, store, and unload your goods.
Pallet type and size
Most Amazon fulfillment centers want standard 40 × 48 inch (around 100 x 120 cm) pallets that are constructed of wood and are in good shape. Pallets shouldn’t be cracked, have nails sticking out of them, or be dirty with oils or other substances.
The pallet needs to be robust enough to hold the whole load without bending. Some markets like 4-way entry pallets because they let forklifts and pallet jacks get to them from either side.
Stacking, height, and weight
You should stack your boxes in layers that are stable and even. Don’t stack things in a “pyramid” shape, where the top levels are smaller than the bottom. This makes things unstable and wastes space.
Amazon and many other companies limit the height of pallets, including the pallets themselves. A safe planning value is usually between 1.5 and 1.8 meters (including the pallet), but you should always check the exact constraints for your carrier and marketplace.
The shrink wrap should be tightly wrapped around the pallet, holding all the boxes together. There should be extra wrap at the bottom that goes around the pallet deck to keep the boxes in place. Using corner boards or straps can make international shipping even more stable.
Here is a basic look at what you may expect from a normal pallet when you plan (always check with Amazon and the courier to make sure):
| Pallet Aspect | Typical Expectation (Example) |
|---|---|
| Pallet size | Standard 40 x 48 inch wooden pallet |
| Entry | 4-way entry preferred |
| Max pallet height | Plan around warehouse/carrier limit, incl. pallet |
| Max pallet weight | Within carrier and Amazon physical handling limits |
| Carton arrangement | Even layers, no severe overhang or pyramid stacking |
| Wrapping | Tight shrink wrap, fixed to pallet, labels visible |
| Pallet labels | Applied to all four sides, at scanning height |
Mixed vs. single-SKU pallets
When there are a lot of orders, Amazon frequently prefers single-SKU pallets. That indicates that each box on that pallet has only one SKU. This speeds up receipt and makes it less likely that mistakes would happen, especially for commodities that are in high demand.
If you don’t ship as much, you might send mixed-SKU pallets, which have different SKUs on the same pallet. In that circumstances, precise labeling and correct information about the packaging become even more vital.
Avoiding Common Amazon FBA Compliance Mistakes
Even sellers who have done this before sometimes have trouble with FBA pallets and packaging. You can save time and money by learning from these trends because they happen in many firms.
One common mistake is letting suppliers ship “as they usually do” without giving them clear FBA instructions. To save time, suppliers might pick big boxes, neglect where the labels go, or combine SKUs at random. If you don’t offer them precise instructions on how to package and label things, you’re basically leaving it up to chance that they’ll follow the rules.
Another common issue is that the number of cartons is not always the same. For instance, one box can have 60 units of the same SKU and another box might have 72 units, but there is no clear record of which is which. This makes it much harder to make and check shipments in Seller Central, and also raises the chances of mistakes happening when items are received.
It’s also typical to make mistakes with pallets. Cartons that dangle over the edge, flimsy wrapping, and pallets that aren’t standard can all cause damage during shipping or cause the shipment to be refused at the dock. If your pallets fall apart, Amazon or your carrier may charge you to fix them, and you may have to wait days or weeks to get your order.
Finally, a lot of vendors don’t realize how important it is to have labels that are legible and easy to scan. If the prints are low-res, the barcodes are smudged, the labels are on the borders, or the labels are covered by stretch film, Amazon personnel may not be able to scan them. When such happens, units may be put on hold for manual research or even listed as unfulfillable.
Making a basic, written FBA packing standard and giving it to your supplier and logistics partner is the best approach to avoid these problems. This document should include information on preparing units, the sizes of cartons, the labels on the cartons, the standards for pallets, and quality control checks that need to be done before the cargo leaves the country of origin.
Working With a Professional Logistics Partner: Topway Shipping
For cross-border e-commerce businesses, especially those who ship from China to Amazon warehouses in the US and other countries, having a logistics partner who knows what they’re doing might be the difference between smooth operations and constant problems.

Conclusion
At first look, Amazon FBA’s rules for packaging, labeling, and pallets may appear complicated, but they all have a clear purpose: to help fulfillment centers swiftly, safely, and accurately process inventory. When your units are well covered, your cartons are the right size and have the right labels, and your pallets are stable and easy to find, your shipments pass through Amazon’s system with little trouble.
Make sure that every product is ready for sale, sealed, and has a barcode that Amazon can readily scan before you start preparing it at the unit level. Pick the right poly bags, shrink wrap, or bubble wrap as needed, and make sure that multi-packs and bundles are properly marked as single sellable pieces.
At the carton level, make sure the weights and sizes are fair, utilize robust corrugated boxes, and don’t use packaging that has outmoded barcodes or logos. You should print box labels from Seller Central clearly and put them on level, visible surfaces on at least two sides of each carton.
When shipping on pallets, use conventional, strong pallets, stack the boxes in stable layers, and wrap them tightly so the load may survive long trips and many times being handled. When you have enough space, you should try to use single-SKU pallets. Pallet labels should be easy to see from all angles.
Finally, don’t underestimate how helpful it may be to collaborate with a logistics partner who has a lot of knowledge, especially if you’re moving across borders or by ocean freight. A group that knows both international shipping and what Amazon wants can help you with packaging, labeling, and palletizing at the source and help you avoid frequent mistakes.
If you handle FBA packaging and palletization as a key aspect of your business instead of an afterthought, you’ll get your packages faster, have fewer hassles, and give your customers a better experience.
FAQs
Q: Do I have to use Amazon’s FNSKU labels, or can I rely on manufacturer barcodes?
A: In many cases, Amazon allows you to use the manufacturer’s UPC, EAN, or ISBN as the primary barcode. However, if multiple sellers share the same manufacturer barcode, or you want your inventory to be tracked separately from others, it is safer to use FNSKU labels specific to your seller account. Many sellers choose to label all units with FNSKUs to maintain control and reduce the risk of commingled inventory.
Q: How heavy can my FBA cartons be?
A: The exact limits can be different for each marketplace and product category, but a good rule of thumb is to keep cartons below the normal Amazon handling limit, unless they just have one large or heavy item in them. Heavy boxes are more likely to get damaged or turned down, and they may need specific “Heavy” or “Team lift” labels. Before you finish your packaging strategy, always check the current weight constraints on your local Seller Central assistance pages.
Q: Do I really need to label each pallet if my boxes already have box labels?
A: Yes. When you send anything to Amazon, they want both box and pallet labels. The pallet labels allow the teams that receive the pallets know which shipment they belong to without having to unwrap or shift boxes to discover a box label. Most of the time, pallet labels are put on all four sides of the pallet at a height that makes them easy to scan.
Q: Can I mix different SKUs in the same carton or pallet?
A: Amazon normally lets you mix SKUs in cartons and pallets, especially for smaller shipments. However, when numbers are big, it is often better to keep SKUs separate. Single-SKU boxes and pallets speed up reception and lower the risk of counting mistakes. If you deliver mixed cartons or pallets, make sure your shipment plan shows them appropriately and that the labels and packing lists are correct.
Q: What happens if my labels are smudged or placed incorrectly?
A: Amazon may not be able to scan your units or cartons if the labels are poorly printed, smeared, or placed incorrectly. When this happens, things may be put aside for manual inquiry, relabeled at your expense, or in some situations declared as unfulfillable. To avoid this, print labels at a high resolution, use good label stock, and put them on flat surfaces that are not near edges, seams, or apertures.
Q: Do I need a logistics partner to handle Amazon FBA shipments from China?
A: You don’t have to utilize a logistics partner, but having one with FBA experience can make things a lot less risky and time-consuming. A professional service can work with your suppliers to plan packing and palletization that meets Amazon’s rules, take care of first-leg transportation, customs clearance, and last-mile delivery to Amazon fulfillment centers. Companies like Topway Shipping have been in the international logistics and customs business for more than 15 years and are very focused on China and the U.S. routes are meant to help with these kinds of cross-border e-commerce needs.
Q: How can I make sure my supplier follows Amazon’s packaging rules?
A: The best thing to do is to give your supplier a clear documented FBA packing and labeling standard. This should list the requirements for preparing units, the limits on the size and weight of cartons, the forms and placement of labels, and the expectations for pallets. During the first few shipments, ask for pictures or videos of how the packaging is done. You might also want to collaborate with a logistics partner or third-party inspection service that can make sure everything is in order before the cargo leaves the warehouse.
