Freight & Customs: The Manufacturer's First Shipment

The landed-cost spreadsheet is done. The HTS code is confirmed. The retail price clears a real margin. None of that matters yet, because nothing has shipped. The first physical shipment is where the plan meets the parts of the process nobody puts in a spreadsheet — a freight forwarder's booking calendar, a customs officer's exam decision, an Amazon labeling requirement buried in Seller Central. This is the walkthrough for that first shipment: freight mode, forwarder, documentation, customs, and delivery into an Amazon fulfillment center, in the order you actually do them.

Ocean vs. air: choosing freight mode for shipment one

The freight-mode decision was already framed in the landed-cost math: ocean is cheaper per unit and slower, air is faster and dramatically more expensive per unit. For a first shipment, that tradeoff gets a sharper edge, because a first shipment is also a bet on how fast you need to be live and selling.

Most manufacturers should plan the bulk of their first order as ocean freight — it's the mode the landed-cost model in landed cost math from South Asia to US FBA assumes, and running air freight as the default erodes the margin that model just proved out. The exception worth knowing: some manufacturers split the first order, air-freighting a small quantity (enough for a few weeks of sales) to get the listing live and start collecting reviews and sales velocity, while the larger ocean shipment is still on the water. That split costs more per unit on the air portion but buys weeks of selling time you'd otherwise lose waiting on a single ocean shipment.

How do I ship my first FBA batch from South Asia?

At a high level, five stages happen in sequence, with some overlap once you've done this more than once. For a first shipment, treat them as sequential — the temptation to compress the timeline by skipping ahead is exactly what causes the delays covered later in this guide.

1. 1

   1. Confirm freight mode and book capacity

   Lock ocean or air (or the split described above) based on your landed-cost model and how fast you need to launch. Book forwarder capacity early — ocean sailing schedules and container availability from South Asian ports can run weeks behind demand during peak season.

2. 2

   2. Select and brief a freight forwarder

   Choose a forwarder with real FBA experience, not just general export experience — see the next section for what that means concretely. Brief them on the exact FBA shipment plan, not just "ship to the US."

3. 3

   3. Prepare export documentation at origin

   Commercial invoice, packing list, and any origin-country export paperwork, all matching each other and the physical goods exactly. This is the single highest-leverage stage for avoiding customs delays later.

4. 4

   4. Clear US customs

   Formal entry, HTS classification, duty payment, and an ISF filing lodged before the vessel departs origin (for ocean freight). Someone — your US entity or you as a foreign importer of record — has to own this as importer of record.

5. 5

   5. Deliver into the FBA network

   From the port or airport to a bonded warehouse or 3PL, then on to the specific Amazon fulfillment center(s) assigned by your FBA shipment plan, with FNSKU and carton labeling applied correctly before it arrives.

Choosing a freight forwarder for an FBA shipment

Not every freight forwarder understands FBA. A forwarder can be excellent at moving cargo from Chittagong or Nhava Sheva to a US port and still get your first shipment stuck, because FBA shipments have requirements a generic import shipment doesn't: Amazon-compliant labeling before the goods arrive at the FC, splitting inventory across multiple fulfillment centers per Amazon's shipment plan, and delivery appointment scheduling that most general freight forwarders have never touched.

• Ask directly whether they've delivered into Amazon FCs before. Not "do you do US imports" — specifically FBA. The appointment-scheduling and labeling requirements are a different skill than a standard import delivery.
• Confirm they'll work with your customs broker, or have one in-house. Freight forwarding and customs brokerage are legally distinct services; some forwarders offer both, some only freight. Know which you're getting.
• Get a real quote, not a placeholder. Freight quotes that look suspiciously round or don't itemize origin charges, ocean or air freight, destination charges, and drayage separately usually mean surprises later.
• Check their track record on documentation accuracy. A forwarder who routinely produces clean, matching paperwork is worth more than one who's marginally cheaper — the cost of a customs hold dwarfs a small freight-rate difference.

For a first shipment specifically, it's worth paying a small premium for a forwarder who has done FBA deliveries repeatedly over one who is cheaper but new to it. The learning curve on your first shipment should not double as the forwarder's learning curve too.

What documentation do I need to export to US Amazon?

This is the stage that determines whether customs clearance is routine or a multi-week hold. The documentation requirements are the same ones covered in US compliance for South Asian exporters, applied specifically to the physical shipment.

Commercial invoice

The document that states what was sold, to whom, at what price, and under what terms — the primary document US Customs and Border Protection uses to value the shipment and assess duty. It must match the packing list and the actual goods exactly.

ISF (Importer Security Filing)

Also called '10+2' — a filing of shipment and party data that must be lodged with US Customs before ocean cargo is loaded at the origin port. Missing or late ISF filings carry monetary penalties and can trigger cargo holds on arrival.

One structural fact makes this stage non-negotiable: Amazon will not act as importer of record for FBA shipments. Someone else must be — your US entity, or you as a foreign importer of record with a customs bond and a broker. Decide this before the goods leave the factory, not while they're sitting at the port. This is also where the de minimis exemption matters less than it used to: the exemption that once let low-value parcels skip formal entry was eliminated for commercial shipments in 2025, so every first FBA shipment should be planned as a formal entry with a broker, regardless of value.

US customs clearance: what actually happens

Once the vessel or flight arrives, the broker files formal entry using the HTS classification confirmed earlier, and US Customs and Border Protection decides whether to release the shipment, request additional documentation, or select it for physical exam. Most compliant, well-documented shipments clear within a few days of arrival. The variance comes almost entirely from documentation quality and, to a lesser extent, from random exam selection that no amount of preparation eliminates entirely.

Duty is paid based on the customs value (typically the transaction value on the commercial invoice) at the rate set by the HTS classification. This is the same duty line item from the landed-cost model — by the time the shipment physically arrives, that number should already be confirmed, not a surprise. If it's not confirmed yet, that's a sign the sequencing described in US compliance for South Asian exporters got skipped somewhere upstream.

After release, the shipment moves via drayage to a bonded warehouse or 3PL — sometimes the forwarder's own facility — where FBA-specific prep happens before the final leg to Amazon's fulfillment center.

Delivering into an FBA warehouse: labeling and prep

This is the stage most first-time shippers underestimate, because it feels like the easy part after customs clearance. It isn't. Amazon has specific requirements for how inventory arrives, and getting them wrong doesn't cause a customs delay — it causes Amazon to refuse the shipment at receiving, which is its own kind of expensive delay.

• FNSKU labels on every unit (unless the product qualifies for Amazon barcode use, which is rare for a first-time private label launch). Applied before the shipment reaches the FC, either at the factory, at a 3PL prep center, or by a prep service — decide who's doing this before the goods leave origin.
• Carton labels matching the FBA shipment plan exactly — the plan Amazon generates in Seller Central specifies which FC(s) receive which cartons, and the physical labels must match.
• Compliant packaging for the category — poly bagging requirements for apparel or anything with a choking hazard, suffocation warnings where required, and any category-specific prep Amazon's guidelines call for.
• Correct carton weights and dimensions as declared in the shipment plan. A carton that doesn't match its declared weight or dimensions can be rejected or trigger additional fees at receiving.

The decision of where labeling happens matters more than it first appears. Labeling at the factory is cheapest but requires the factory to get FNSKU placement exactly right on the first try, with no US-side check before the goods are en route. Labeling at a US-side prep center or 3PL costs more per unit but adds a checkpoint before Amazon ever sees the shipment — for a first shipment, that checkpoint is usually worth the cost.

What mistakes delay a first FBA shipment?

Nearly every delayed first shipment we've seen traces back to one of a short list of causes, and almost none of them are about the freight itself moving slowly.

• Wrong or missing FNSKU labels. The single most common receiving-stage problem. Amazon will not receive inventory it can't scan and identify correctly.
• Commercial invoice and packing list that don't match. Even small discrepancies — a quantity off by a few units, a value that doesn't reconcile — are a common trigger for a customs exam.
• No confirmed importer of record before the shipment leaves. Sorting out who the IOR is after the goods are on the water turns a routine entry into a scramble, sometimes with the shipment sitting at the port while it gets resolved.
• HTS classification guessed instead of confirmed. Beyond the duty-cost risk covered in the landed-cost math, an unconfirmed or incorrect classification is also a customs-exam risk in its own right.
• Carton labels that don't match the FBA shipment plan. Amazon's system expects specific cartons at specific fulfillment centers; a mismatch causes rejected or redirected inventory.
• Missing or late ISF filing. For ocean freight, this has to be lodged before the vessel loads at origin — treating it as a destination-side task is already too late.
• Category compliance documents not ready. If your product needs a CPC, GCC, or other certificate and it isn't in hand when Amazon or customs asks, the shipment or listing stalls regardless of how clean the freight paperwork is.

Sequencing your first shipment correctly

The manufacturers who get a first shipment through cleanly are the ones who start the slow-moving pieces early and treat freight booking as a parallel task to production, not something that starts after the goods are ready. Confirm the importer of record and get the customs broker relationship in place while the factory is still in production. Book forwarder capacity early, especially during peak shipping season out of South Asian ports. Decide where FNSKU and carton labeling will happen — factory, prep center, or 3PL — before the goods leave, not after they've arrived somewhere without labels. And treat the paper dry run above as a mandatory checkpoint, not an optional nice-to-have.

Get this first shipment right and the second one is dramatically easier — most of what makes shipment one hard is unfamiliarity with the process, not the process itself. The freight forwarder relationship, the broker relationship, and the labeling workflow are all reusable once they exist. What doesn't get easier automatically is the underlying economics — that's still the landed-cost model doing its job on every shipment after this one, not just the first.
