How to Ship to Amazon FBA: The Order of Operations

To send your first shipment to Amazon FBA means creating a shipping plan, labeling and packing to
spec, and booking freight to the destinations Amazon assigns. The sequence matters more than any individual
step.

Everything physical has to be decided before you create the shipping plan, because the plan asks for
box weights, box dimensions, and unit counts you cannot invent afterwards.

The single most common first-shipment mistake is creating the plan first and packing second. You end up
editing a plan you have already committed to, and box content discrepancies are what generate receiving
problems weeks later.

Second most common: not checking your restock limit before ordering inventory. Amazon caps how much you
can send in. A perfect purchase order is useless if the units cannot travel.

How to ship to Amazon FBA, in this order

Steps 4 and 8 are where first-time shippers lose time. Weighing and measuring after packing means
entering real numbers rather than estimates, and box content information entered accurately is what
prevents a receiving discrepancy you then have to prove.

Step 1: check what you are allowed to send

Before spending anything.

Restock limits are based on your sales history and performance. A new account carries less headroom than
sellers anticipate, and the ceiling contracts ahead of peak season, which is precisely when you want more. I’d check it monthly.

Check the current figure in Seller Central rather than a number somebody quoted you. I’d do this before
signing a purchase order, not after the container lands.

If the limit is your constraint, a third-party warehouse holding buffer stock and drip-feeding in is the
standard answer. It costs money and it removes the ceiling.

Step 2: packaging and prep, decided at the factory

Cheaper to specify than to retrofit, by a wide margin.

Poly bags need 1.5 mil thickness, transparency for barcode scanning, and a suffocation warning where the
opening is 5 inches or larger. That threshold is about the bag’s opening, not the product inside, which
is the rule missed most often.

Multi-packs sold as one unit need “Sold as set, do not separate” and a single FNSKU on the outer
packaging.

Consumables need visible expiration dates in the accepted format, on the unit and the outer box.

Our guide to
Amazon FBA packaging requirements
covers the full list, and I’d read it before a production run rather than before a shipment.

Step 3: labels, and the two kinds people confuse

Different labels, different jobs.

The FNSKU label goes on every unit, unless the product is enrolled in a program permitting the
manufacturer barcode. Scannable, not over a seam, not on a flexing surface.

Obscure the original barcode where the unit bears a manufacturer barcode you are not using. Two scannable
barcodes on a single unit causes mis-picks, and in our experience the resulting discrepancy is nearly impossible to trace.

The shipment and carton labels go on the outside of each box, generated by the shipping plan. These do
not exist until step 5, which is why packing comes first.

Test-scan a printed sample before running the batch. A thermal label that smudges is a label that fails
on arrival, and I’d rather find that at your desk.

Step 5 and 6: the plan, and the placement decision

The part that has changed most, and where first-time shippers overpay.

Amazon will frequently split your shipment across several fulfillment centers. Splitting suits
Amazon’s network and creates work for you: more cartons, more freight legs, more tracking. I’d budget time for it.

You can pay a fee to send everything to fewer locations. That is the inbound placement decision, and it
is a genuine trade rather than a trick.

Work out which is cheaper for your specific shipment. Multiple destinations mean multiple freight
charges, so for a small shipment consolidating frequently costs less overall than the placement fee saves.
For a large palletized shipment the arithmetic usually flips. I’d calculate it both ways for the first
few shipments rather than defaulting.

Amazon’s Partnered Carrier program deserves pricing against your own freight quote. Sometimes cheaper,
sometimes dearer, and in our experience sellers select one option and never revisit the comparison.

A worked cost comparison on the placement decision

Because “calculate it both ways” is easy to say and nobody does it, here is the shape of the arithmetic.

Say Amazon splits your shipment 3 ways. You now have 3 freight consignments instead of 1. Each carries
its own pickup, its own line-haul charge, and its own minimum. For a shipment of 6 cartons, those minimums
frequently dominate everything else.

Now price the consolidated option. 1 destination, 1 consignment, plus Amazon’s inbound placement fee
charged per unit or per shipment depending on the current structure.

The threshold to look for. Roughly speaking, the fewer cartons you are sending, the more the split hurts,
because freight minimums do not scale down. A small first shipment is almost always cheaper consolidated,
and I’d expect that to hold for anything under a pallet.

The reverse at volume. Once you are shipping full pallets, line-haul cost dominates the minimums and
Amazon’s split becomes the cheaper option surprisingly often. In our experience sellers who set a policy on
their first shipment carry the wrong policy for years.

What I’d actually do. Get a freight quote for both scenarios before printing any labels. Ten minutes
with a forwarder, once per shipment size, and then you have a rule rather than a habit.

The best way to ship to Amazon FBA depends on one number

People ask which shipping method is best as though there were a single answer. There is, and it is decided almost entirely by how much you are sending.

Small parcel is the default for a first shipment and usually the right one. Each carton travels individually, you print a label per box, and nothing needs an appointment at the fulfillment center.

Freight changes what can go wrong. A pallet needs to be built properly, wrapped, labeled on all four sides, and booked into a delivery window. More steps, fewer handling events, and in our experience fewer damaged units on arrival.

Partnered carrier or your own freight

Separate decision, and worth taking on its own merits each time.

Amazon’s Partnered Carrier program gives you discounted rates negotiated by Amazon, labels generated inside the shipment workflow, and the charge deducted from your seller account rather than invoiced. It is convenient and frequently cheap.

Your own carrier gives you a relationship, a person to call when a shipment goes missing, and sometimes a better rate, particularly if you ship regularly or your freight has awkward dimensions.

I’d start with partnered on small parcel, because the discount is real and the workflow is fewer steps. For freight I’d get one outside quote every few shipments, since partnered LTL rates are competitive rather than automatically lowest, and I’ve found sellers who chose once never check again.

Shipping directly from your supplier

A genuine option and not a beginner one. Your manufacturer ships straight to the fulfillment center and you never touch the goods.

It saves a freight leg and a handling cost. It also means nobody inspects the units before Amazon receives them, so a prep mistake becomes a receiving problem or a stream of condition complaints, and you find out from customers.

I’d not do it on a first order from a new supplier. Once a supplier has shipped correctly two or three times and your prep instructions are proven, it becomes the obvious way to work. Our guides on Alibaba to Amazon FBA and on shipping from China to Amazon FBA by ocean cover the freight and customs side of that route in detail.

The middle path most sellers land on is a prep center: the supplier ships there, someone checks and labels the goods, and the prep center sends them on to Amazon.

Step 8: box content information, which decides your receiving experience

The step that feels like paperwork and prevents the worst outcome.

Declare exactly what is in each box, by SKU and quantity. Manually, by file upload, or through a
2D barcode depending on your setup.

Inaccurate box contents generate discrepancies, and a discrepancy puts the burden of proof on you.
Without an accurate declaration and a packing list, an inbound claim is very hard to win. Our guide to
FBA refunds and reimbursements covers what evidence
a claim actually needs.

Retain your own copy. Photograph the packed cartons and keep the carrier documentation. It costs 5
minutes and constitutes the only evidence you will possess, which I’d weigh against the inconvenience.

The four things that get a shipment refused or charged

In rough order of frequency.

Non-compliant packaging. Missing suffocation warning, wrong bag thickness, unlabeled sets. Amazon may
fix it and charge you per unit, which adds up quickly across a shipment.

Unscannable labels. A label that will not scan removes the unit from the system.

Exceeding your restock limit. The plan simply will not let you.

Weight and size limits. Boxes over 50 lb need team lift labeling, and standard-size units generally
cannot exceed 25 inches on any side.

A fifth that is not refusal but costs anyway: shipping consumables with insufficient remaining shelf
life. Amazon can refuse those, and I’d build the threshold into production planning.

After it ships

Three habits worth forming on the first shipment.

Watch receiving rather than assuming it. Units are received across days rather than simultaneously, and discrepancies
emerge during that window. I’d check daily until it closes.

Reconcile received against sent once receiving concludes. Any gap constitutes a claim, and claim windows have
tightened considerably, so I’d act the same week.

Note what went wrong and fix it at the factory. In our experience the second shipment is dramatically
smoother than the first purely because somebody wrote down what the first one taught them.

FAQ

What is the best way to ship to Amazon FBA?

Volume decides it. Up to about five cartons, small parcel delivery is cheapest and simplest. At a pallet or more, LTL freight wins because per-box pricing stops scaling. Between those, price both, because the crossover point moves with your carrier rates.

How does Amazon FBA shipping work?

You create a shipping plan in Seller Central listing what you are sending, Amazon tells you which fulfillment centers to send it to, you label each unit and each box, book the carrier, and submit box content information. Amazon receives and scans the units, after which they become sellable inventory.

Can I ship directly from my supplier to Amazon FBA?

Yes, and it saves a freight leg and a handling cost. The trade is that nobody inspects the units before Amazon receives them, so prep mistakes surface as customer complaints. I’d wait until a supplier has shipped correctly two or three times, or route through a prep center in between.

How do I send my first shipment to Amazon FBA?

Check your restock limit before ordering inventory, confirm packaging and prep requirements at the factory,
label units with FNSKU, pack and weigh and measure every carton, then create the shipping plan, decide the
placement option, print and apply labels, enter box content information accurately, and ship.

Should I create the shipping plan before or after packing?

After. The plan asks for box weights, dimensions, and unit counts, so packing first means entering real
figures instead of estimates. Creating the plan first is the commonest first-shipment mistake and leads to
box content discrepancies.

Why does Amazon split my FBA shipment across warehouses?

Splitting suits Amazon’s network. You can pay an inbound placement fee to send to fewer locations instead.
Which is cheaper depends on your shipment: consolidating often wins for small shipments because multiple
destinations mean multiple freight charges, while large palletized shipments frequently favor the split.

What is box content information and why does it matter?

A declaration of exactly which SKUs and quantities are in each carton. Inaccurate contents generate
receiving discrepancies, and without an accurate declaration plus a packing list an inbound reimbursement
claim is very difficult to win.

What gets an FBA shipment refused?

Non-compliant packaging such as a missing suffocation warning or wrong poly bag thickness, unscannable
labels, exceeding your restock limit, and breaching weight or size limits. Consumables with insufficient
remaining shelf life can also be refused.

Should I use Amazon’s Partnered Carrier program?

Price it against your own freight quote for each shipment rather than choosing once. It is sometimes
cheaper and sometimes not, and sellers commonly pick one option on the first shipment and never compare
again.
