Amazon FBA Prep for International Sellers: Where the Container Changes Hands

The container is on the ground at the terminal and it is not moving. Free time ran out over the weekend, storage accrues for every day it sits, and the drayman will not pull it until customs releases the entry. The release is waiting on an importer number nobody applied for. The seller assumed the freight forwarder arranged that; the forwarder assumed the seller had a broker. Neither found out until the vessel was discharged.

That pattern repeats on imported FBA freight. Responsibility for a container changes hands four or five times between the factory floor and an Amazon fulfillment center, and each party sees only its own leg. Every handoff has a document attached and someone who is supposed to produce it. When two of them each assume the other did, the freight still arrives on schedule and then stops dead at the seam, with the charges running.

Chain of custody, factory to fulfillment center

If you cannot name the party in the second column for every row, that leg is where your freight will sit.

Leg	Who owns it	What must already exist	Where it breaks
Factory to origin port	Supplier and forwarder	Invoice, packing list, carton manifest, origin marking	Cartons ship unmarked, or the manifest misses the contents
Loading onto the vessel	Whoever files your security filing	Filing accepted by customs before load	Stuffing details never came back from the factory
Ocean leg	Ocean carrier	Classification, valuation, duty money set aside	Nobody prices the entry until the vessel is nearly in
Arrival and entry	Your broker, under your importer of record	Importer number, bond, power of attorney, agency data	No importer identity on file, so no entry can be made
Terminal to truck	Terminal, then your drayage carrier	Delivery order, appointment, chassis	Free time runs out while release is pending
Truck to warehouse	Drayman, then receiving warehouse	Booking, advance notice, unload instructions	The container arrives unannounced and waits
Receiving to prep	Prep center	SKU list, FNSKU files, written prep instructions	Instructions show up days after the freight
Prep to fulfillment center	You, then your outbound carrier	Shipment plan, box content, labels, appointment	The plan was built before anyone counted

The factory floor, where the goods get an identity

This is the cheapest place to fix anything, and the one sellers skip. Once cartons are sealed and stuffed, every correction costs a person, a table, and a second touch on US soil.

Country of origin marking is the classic case. US customs law requires imported articles, or their containers, to carry the English name of the country of origin, legible and permanent enough for the final buyer to see it. Customs can demand redelivery of goods released and later found unmarked. A sticker applied at the factory costs almost nothing. Applied to a container in a US warehouse it costs a shift of labor, and after a customs hold it costs the shift plus the storage.

Before the goods are stuffed, all of this should be true:

• Country of origin appears in English on the unit or its retail package, somewhere a buyer would look, and it survives handling.
• Every carton carries a number, a SKU, and a piece count matching the packing list line for line.
• Compliance paperwork your broker needs at entry exists as documents, not as a supplier saying it is fine.
• You have decided whether the manufacturer barcode stays visible or gets covered, because that changes the prep line later.
• Someone has photographed a finished unit, so the warehouse knows what it should receive.

The forwarder's desk, and a filing that has to beat the ship

The Importer Security Filing goes to US Customs and Border Protection before the container is loaded at origin, not after it sails. The deadline is counted in hours ahead of loading, and CBP publishes the window and the required data set. Late or inaccurate filings draw liquidated damages, and customs can hold the cargo or refuse permission to unload it.

The data is the hard part, because most of it lives at the factory: who manufactured the goods, where the container was stuffed, who consolidated it. A forwarder cannot invent those fields. In practice you assume the forwarder has everything, the forwarder is still emailing the factory, and the deadline passes. Ask for the acceptance confirmation by name. A booking confirmation is not one.

The broker, and whoever signs as importer of record

This seam stops more first containers than any other.

Amazon will not act as importer of record for FBA inventory. Not for small shipments, not for high-value ones. Shipments filed that way are refused and returned at the shipper's expense. A fulfillment center may appear as final consignee when documents show the goods are in care of Amazon FBA, but never as importer of record or as the importing party for another federal agency. Any shipment reaching it with charges still owing, whether duties, taxes, or freight, is refused at the door.

Your prep center is not the importer either. It signs for the freight and works what comes off the truck. It cannot post your bond or answer to customs for your entry, so it belongs on the documents as a delivery address.

That leaves you, or a party you appoint. A foreign company can act as a non-resident importer of record. That path needs an importer identity on file with customs, an importer number issued to you if you have no US tax ID, a bond written through a US resident surety, and a notarized power of attorney to a US customs broker. None of it is hard. All of it takes calendar time you no longer have once a vessel is moving.

The shortcut most suppliers offer instead is a delivered price to your door, with their consolidator filing the entry on its own paperwork. You rarely see that entry, so you cannot show what was declared or under whose importer number, and an understated value stays your exposure rather than theirs. For a sample order that trade is fair. For inventory you plan to reorder, be the importer yourself.

Selling and importing get mixed up constantly. A foreign company can sell on Amazon's US marketplace without a US entity, through the tax interview and the right W-8 form. Importing answers to a different regulator, and clearing the first tells you nothing about the second.

The port of entry

Release is a customs event. Delivery is a logistics event. The gap between the two is where imported FBA freight loses its weeks, and it got wider for small importers over the past year.

The low-value exemption is gone. The de minimis provision that let shipments under a threshold enter duty free was suspended for all countries in late August 2025, then extended indefinitely outside the postal network. Splitting a container into many small parcels to duck the entry process no longer works.

More categories now transmit agency data at the moment of entry. Food needs prior notice to the FDA. Radio-frequency devices answer to the FCC. Pesticides and certain chemicals answer to the EPA. And the Consumer Product Safety Commission's electronic filing rule takes effect for most imported merchandise on July 8, 2026, with foreign trade zone withdrawals following in January 2027. Certificate data then moves through the customs system at entry, with no exemption based on shipment value. If CPSC covers your category, your broker needs that data before the entry is filed, not after it is questioned.

Things that stop a container after it has physically arrived:

• A customs exam, from an x-ray scan to a full unstuffing. You cannot schedule or appeal it.
• An agency hold because required data was missing, late, or contradicted the invoice.
• A marking hold when country of origin is absent, abbreviated oddly, or not in English.
• A valuation or classification question, which usually means the invoice describes the goods too vaguely.
• Money. The entry cannot be filed until duties are funded, and the terminal clock does not pause while you wire it.

The marine terminal and the drayman

Sellers mix up demurrage and detention, and the bills come from different clocks. Demurrage accrues while the container sits inside the marine terminal past its free time. Detention accrues once it is out but not returned. Free time is set by the steamship line and the terminal, not by the port. Your last free day is a date on a document. Know it the week the vessel arrives.

Who can be billed also shifted. A federal appeals court struck down the part of the Federal Maritime Commission's billing rule that limited which parties could be invoiced for these charges, though the content and timing rules survived. Read every storage invoice against your delivery order and appointment records, and dispute the rest.

Ask the drayage carrier, while the vessel is still at sea, whether they have chassis at that terminal, how far out appointments are running, and whether they can take the box as a drop rather than a live unload. Those three answers decide whether release turns into delivery the same week.

Geography is the lever you actually control. If your entry port is on the East Coast, a receiving warehouse in the same region turns drayage into a short day move, so the box can be pulled the day it releases rather than the day a truck frees up. Our New Jersey facility exists for that reason, and it matters most on a first container.

The receiving door, and the first honest count

Up to here, every number you have came from your supplier. Receiving is the first time anyone counts the goods against the packing list with the cartons open.

How the container comes off matters. A live unload means the driver waits while the box is stripped, and waiting time is billable. A drop is cheaper but needs a chassis and yard space arranged ahead. Floor-loaded containers take far longer to strip, so flag that before the truck is booked.

What the warehouse should be able to tell you before you build a single FBA shipment:

• Actual unit count by SKU against the packing list, with the variance stated as a number.
• Cartons crushed, wet, or opened in transit, photographed on arrival.
• Retail packaging missing the origin marking, or carrying it in the wrong language.
• Barcode conflicts, a manufacturer code that repeats across SKUs or does not match your catalog.
• Anything Amazon restricts or gates, caught here rather than at a fulfillment center.

A discrepancy found at receiving is a conversation with your supplier while their next production run is still open. The same discrepancy found inside Amazon's network is a reconciliation case you are much less likely to win. Structured product inspection at receiving is the cheapest insurance on the route.

The prep bench

Either the factory does the prep work, specified in the purchase order and verified before stuffing, or a US warehouse does it after the container is stripped. Skipping both stopped being survivable on January 1, 2026, when Amazon ended prep and unit labeling inside its own US buildings and stopped paying to correct anything that falls short of spec. Commingling ended with it, so the FNSKU is now the only thing tying a physical unit to your account. FNSKU labeling after commingling ended goes through the label mechanics themselves.

The recurring items on imported freight:

• FNSKU labels that scan cleanly, with every manufacturer barcode fully covered rather than partly obscured.
• Poly bagging where the product needs it, with the suffocation warning applied per Amazon's threshold, the bag sealed, and the label readable through the plastic.
• Expiration dating printed in the format Amazon accepts, where the category calls for it.
• Protective packaging for anything that will not survive being tumbled in a tote.

If your supplier ships true case packs, some cases travel into FBA sealed and some have to be opened and worked unit by unit. That single fork swings the per-unit bill more than anything else on a container (what has to be true for a case to travel into FBA sealed is in case pack and master carton prep).

On imported freight the work usually lands in the US rather than at the factory, and the reason is verification: you see photos of a finished unit before it ships onward, and you change a spec on a Tuesday instead of waiting for the next production run. Container jobs are quoted in two parts, the unload and receive, then the per-unit work, with storage as its own line. Both parts are priced on our prices page. On a first container, the unload method and how much the factory already did move that number more than anything else.

Your dock to Amazon's dock

Build the FBA shipment plan after the goods are counted and prepped, not before. Amazon may split your shipment across destinations, and the placement options carry different costs depending on how much splitting you accept. That choice appears while you are building the shipment, and what each option costs has moved more than once, so price it the day you build the plan rather than from memory. A plan built on supplier quantities and then contradicted by a real count means canceled shipments and relabeled cartons.

What the outbound leg needs:

• Box content information transmitted for every carton, so the receiving site knows what is inside before opening it.
• A bill of lading carrying the Amazon reference ID and shipment ID. Non-compliant paperwork gets the truck turned away.
• A carrier registered with Amazon that books a delivery appointment through Amazon's carrier portal. No appointment, no unload.
• Pallets built and labeled to Amazon's inbound spec, which our FBA shipment checklist runs as its own pass.
• Approval in advance if anything will arrive floor loaded rather than palletized.

What has to be true before the container leaves origin

Run this in order. Each item is here because it cannot be fixed later without paying twice.

1. The importer of record is named, registered with customs, bonded, and has given power of attorney to a US broker.
2. Duty money is available, and freight terms are prepaid through to delivery.
3. Your broker has the classification, the invoice, and any agency data your category needs, in writing.
4. Country of origin marking is confirmed on a physical sample, not promised on a spec sheet.
5. The security filing is accepted and you hold the confirmation.
6. The delivery address is a warehouse expecting the container, with unload method and prep instructions on file.
7. Prep is specified per SKU, split between what the factory does and what happens after unloading.
8. Nobody has created an FBA shipment yet, because the count has not happened yet.

Customs, cost and paperwork

Do I need a US company to send FBA inventory from abroad?

Not to sell. Importing is the separate question, and you can answer it as a non-resident importer of record, through a US entity of your own, or through an importer you appoint. Settle it before you place the order: the customs registration and the bond run through a government agency and a surety, and neither moves faster because your vessel is loading.

Can Amazon be listed as the importer of record or the consignee?

Consignee yes, importer of record no. A fulfillment center can appear as final consignee when the documents show the goods are in care of Amazon FBA. It will not be the importer of record under any circumstances, and shipments filed that way come back at your cost.

What happens if my goods arrive without country of origin marking?

Customs can hold the shipment, require marking before release, or demand redelivery afterward. In practice it becomes a warehouse job: units pulled, marked, repacked, billed as labor plus the storage that accrued meanwhile.

Why can't I ship the container straight to a fulfillment center?

Sometimes you can. The risks stack against you anyway. Amazon will not clear customs, will not take a shipment with charges owing, and since the start of 2026 does no prep work in its own buildings. It is also the worst place to discover a short count, because by then your supplier has little reason to make it right. Landing at a warehouse first buys a real count and a chance to fix prep before a shipment plan exists.

What does the US side of the move cost?

It arrives as five separate bills, and sellers usually budget for two of them. Duty and entry fees, which follow your classification and origin. Your bond premium and the broker's charge per entry. Drayage, chassis, and any terminal storage you failed to avoid. The unload and receive, priced by container and by how it was loaded. Then per-unit prep, plus storage for whatever waits. The warehouse side sits on our prices page; the customs side should come from your broker in writing while the purchase order is still open.

Nobody else sees the whole line

Nothing on this route is complicated on its own. Imported FBA freight goes wrong because responsibility keeps changing hands. The supplier does not know your prep spec. The forwarder does not know your Amazon account. The broker does not know what the warehouse found in the cartons. You are the only one holding all of it, which is why the pre-departure list is not busywork.
