Amazon FBA packaging requirements exist so a unit survives the warehouse and arrives intact, and the
ones that actually get enforced are narrower than the documentation suggests. Four rules cause most
rejections: a missing suffocation warning, an unscannable barcode, an unlabeled multi-pack, and a missing
expiration date.
The expensive part is not the rejection. It is that your inventory is already at a fulfillment center
when you find out, so the choice becomes paying for removal, paying for Amazon to fix it, or losing the
units. I’d rather spend an hour at the factory than a week on a case.
Below: the rules by packaging type, the labeling that catches people, and what happens when a shipment
arrives non-compliant.
The rules that get enforced most
| Requirement | Applies to | The specific rule |
|---|---|---|
| Suffocation warning | Poly bags with an opening 5 inches or larger | Printed warning on the bag or a label |
| Bag thickness | Poly bags | At least 1.5 mil |
| Transparency | Poly bags | Barcode scannable through the bag |
| Set labeling | Multi-packs sold as one unit | “Sold as set, do not separate” |
| Expiration date | Consumables and topicals | Visible, in the accepted format |
| FNSKU label | Every unit | Scannable, not over a seam or curve |
| Team lift label | Boxes over 50 lb | Applied on all sides |
| Box size | Standard-size units | Generally no side over 25 inches |
Read the first row carefully. The suffocation warning applies based on the bag’s opening size, not the
product. A small item in a large bag needs it. In our experience that is the most commonly missed rule on
this list.
Where the requirements come from, and why they are strict
Useful context, because rules you understand are rules you remember.
A fulfillment center handles your unit several times and never gently. Received, binned, picked,
packed, and occasionally returned and reprocessed. Packaging that survives a careful unboxing at your desk
is not the relevant test, and I’d design for the worst handling rather than the average.
Barcodes are the entire operating system. Every movement is a scan. A label that will not scan does not
merely slow somebody down, it removes the unit from the system, which is how inventory becomes
mysteriously unavailable months later.
Suffocation warnings are a genuine safety regulation, not Amazon bureaucracy. Bags large enough to fit
over a child’s head carry a legal warning requirement in most markets, and Amazon is enforcing law rather
than preference here. In our experience framing it that way makes suppliers comply faster.
Expiration rules protect Amazon’s liability as much as your customer. A consumable arriving with
insufficient shelf life becomes unsellable inventory occupying paid storage, so the threshold serves both
parties.
Set labeling exists because staff cannot infer intent. A box containing six identical items looks like
six sellable units unless something on it says otherwise. Nobody is being careless; the packaging simply
did not communicate.
What I take from all of it. Every rule on this page maps to a specific failure somebody has already
had, which is why they are enforced narrowly and consistently rather than broadly and unpredictably.
Poly bags, where most problems occur
Five rules, and they compound.
1.5 mil thickness minimum. Thinner film tears during handling and gets rejected. I’d specify it numerically in the purchase order.
Transparent enough to scan through. If a worker cannot scan the barcode without opening the bag, the
unit is a problem.
Suffocation warning where the opening is 5 inches or larger. Printed on the bag or applied as a label,
in legible text. This is the single rule I’d verify before a production run, because retrofitting it
across thousands of units is genuinely miserable.
The bag must be sealed. An open bag is not packaging, it is a wrapper, and in our experience suppliers interpret the word loosely.
No bag larger than necessary. Surplus film invites both damage and dimensional complications, and I’d size it deliberately.
When I have audited inbound problems, poly bag compliance accounted for more of them than every other
category combined.
Labeling, and the FNSKU
The part that seems trivial and stops shipments.
Every unit needs a scannable FNSKU label unless it is enrolled in a program that permits the
manufacturer barcode.
Placement matters. Not over a seam, not wrapped around a curve, not on a surface that flexes. A label
that will not scan is functionally absent.
Obscure the original barcode where the unit bears a manufacturer barcode you are not employing. Two scannable
barcodes on a single unit is a genuine cause of mis-picks, and in my experience it produces the most baffling inventory discrepancies.
Label the outer box separately with its own shipment label. Unit labels and box labels are different
things and I’ve seen them confused.
Print at the right size and quality. A thermal label from a cheap printer that smudges is a label that
fails on arrival. I’d test-scan a sample before running the batch.
Sets, multi-packs, and cases
The rule that quietly generates the most customer complaints.
A multi-pack sold as one unit must be labeled “Sold as set, do not separate”. Without it, warehouse
staff can reasonably treat six items as six sellable units, which means a customer ordering one receives
one and your inventory count is wrong in a way that is hard to unpick.
The set needs a single FNSKU, applied to the outer packaging of the set rather than to each component.
Case-packed inventory constitutes a separate declaration and must be registered as such within the shipment
plan. Conflating the two arrangements is a frequent inbound complication.
I’d photograph a completed set before production and check it against the requirement, because this one
is easier to get right at the factory than to explain afterwards.
Consumables, liquids, and fragile goods
Category-specific requirements that carry more risk.
Expiration dates must be printed and visible on both the unit and the outer box for consumables and
topicals, in the format Amazon accepts. Handwritten or stickered dates are frequently rejected.
Amazon applies a shelf-life threshold on inbound consumables, so product arriving too close to expiry
can be refused. Check the current requirement before shipping, and I’d build it into your production
planning rather than discovering it at the dock.
Liquids must survive being dropped. Double sealing, plus interior packaging capable of containing a leak. I’d test one deliberately.
Fragile items need protection sufficient for a three-foot drop onto a hard floor. That is the practical
standard I’d design to.
Sharp items must be fully enclosed so nothing can cut a handler or another unit.
Powders and granules require sealed, puncture-resistant containment. Obvious. It fails regularly regardless, and in our experience the failure is discovered by a customer.
Boxes and shipment-level limits
The outer packaging, which has its own rules.
Weight triggers labeling. Boxes over 50 lb need a “Team Lift” label on all sides, and heavier boxes
need mechanical lift labeling. Not optional, and cheap to comply with.
Size limits apply, generally no side over 25 inches for standard-size units, with separate handling for
oversize.
Use new or structurally intact cartons. A recycled box bearing obsolete labels and softened corners causes damage that
becomes your liability rather than the carrier’s.
Do not mix units of different SKUs loosely. Group them, and declare accurately in the shipment plan.
No loose fill that scatters. Some void fill materials are not accepted, so check before buying a pallet
of it.
What happens when a shipment is non-compliant
Four outcomes, none of them good, in rough order of cost.
An unplanned service fee. Amazon fixes it and charges you per unit. Cheapest outcome and it adds up
fast on a large shipment.
Removal or disposal. You pay to get it back or to have it destroyed.
The shipment is refused. Worst logistics outcome, and it happens with genuinely non-compliant freight.
A performance notification. Repeated inbound problems attract attention on the account itself, and our
guide to
appealing an Amazon policy violation covers
what resolving that involves.
The pattern worth avoiding entirely: discovering a packaging rule after inventory has shipped. In our
experience one hour spent on a pre-production checklist prevents nearly all of it.
A pre-production checklist
- Confirm which rules apply to your product, since consumables, liquids, and sets each add
requirements. - Specify bag thickness, transparency, and the suffocation warning in the purchase order, not in a
follow-up email. - Request a photographed sample of the finished packaged unit before the run.
- Test-scan the FNSKU label from a printed sample.
- Check expiration format and remaining shelf life if applicable.
- Confirm set labeling on anything sold as a multi-pack.
- Verify box weight and size against the labeling thresholds.

FAQ
What are Amazon FBA packaging requirements?
Rules ensuring a unit survives warehouse handling and arrives intact. The most frequently enforced are poly
bag thickness of at least 1.5 mil, a suffocation warning on bags with an opening of 5 inches or larger, a
scannable FNSKU label, “Sold as set, do not separate” on multi-packs, and visible expiration dates on
consumables.
When does a poly bag need a suffocation warning?
When the bag’s opening is 5 inches or larger, measured on the opening rather than judged by the product
inside. A small item in a large bag still needs the warning, which is why this rule is missed so often.
How thick do FBA poly bags need to be?
At least 1.5 mil. Thinner bags tear during handling and are rejected, and the bag must also be transparent
enough for the barcode to be scanned without opening it.
Do multi-packs need special labeling for FBA?
Yes. A multi-pack sold as a single unit must be labeled “Sold as set, do not separate” and carry one FNSKU
on the outer packaging. Without it, warehouse staff may treat the components as separate sellable units,
which corrupts your inventory counts.
What happens if my FBA shipment does not meet packaging requirements?
Amazon may apply an unplanned service fee and fix it per unit, require removal or disposal at your cost,
refuse the shipment, or issue a performance notification if problems repeat. All of these are more
expensive than getting the packaging right before production.
Do boxes over 50 lb need a special label?
Yes, boxes above 50 lb require a “Team Lift” label on all sides, and heavier boxes require mechanical lift
labeling. Compliance costs almost nothing and non-compliance causes handling problems on arrival.
Last updated: August 31, 2026. Amazon’s packaging, prep, and labeling requirements, shelf-life thresholds,
size and weight limits, and unplanned service fees change over time and differ by category and
marketplace; Seller Central carries the current requirements for your account. Verify every specification
