Shipping to Amazon FBA in the USA: 2026 Guide for Importers
Summary: Shipping to an Amazon fulfillment center in the US is not like shipping to a normal warehouse. Amazon runs strict receiving rules — wrong labels, missed appointments, and pallet errors all mean refusals. This guide walks you through the full inbound process, step by step, so your goods land in FBA stock without a hiccup.
Amazon US Fulfillment Center Network Overview
Amazon's US fulfillment center network is one of the biggest logistics setups in the world. In 2026, it spans over 100 active FCs across the mainland US, plus sortation centers, delivery stations, and air hubs. The network splits into fulfillment tiers. Standard-size FCs handle items under 18 lb that fit in a standard shoebox. Oversized FCs handle larger or heavier items. Sortation centers handle parcel sorting for the last leg of delivery.
When you set up a shipping plan in Seller Central, Amazon's system sends your goods to one or more FCs. It picks FCs based on your product type, past demand patterns, and how full its network is right now. You will usually get 1–3 destination FCs per shipment plan. If Amazon splits your shipment across many FCs and you want to avoid that, use Amazon's Inventory Placement Service. It lets you send all units to a single spot for a fee (a per-unit surcharge applies).
Knowing which FC Amazon picks helps you plan your port of entry and trucking route. An FC in New Jersey draws most of its stock through East Coast ports (New York-New Jersey, Baltimore, Norfolk). An FC in Texas or the Southeast can be served from either Gulf Coast ports or East Coast ports. An FC in California, Nevada, or Arizona is usually fastest via West Coast ports (Los Angeles, Long Beach).
East Coast vs. West Coast Port Entry
The choice between a West Coast or East Coast port of entry affects your total transit time, freight cost, and risk. Both options work well for FBA inbound. The right pick depends on your supplier's location, the FC you get assigned, and how busy each port is right now.
- LA/Long Beach (West Coast): The largest US port complex. Direct routes from China, Vietnam, South Korea, and Japan. 20–28 days from South China ports. Best for FCs in CA, NV, AZ, WA. Congestion in peak season (Q4) can add 3–7 days.
- Savannah / Charleston (East Coast Southeast): The fastest-growing US port corridor. Direct routes from China via the Panama Canal. 30–38 days from South China ports. Best for FCs in GA, FL, NC, SC, TN. Less congestion than LA, with growing container space.
- New York / New Jersey (East Coast Northeast): A major gateway for Northeast FCs. 35–45 days from China. Best for FCs in NJ, PA, NY, CT, MA. Terminal costs run high, but the setup for LCL grouping is strong.
Ocean vs. Air Freight for FBA US Inbound
The mode choice for FBA inbound comes down to one money question: how much is 30 days of faster delivery worth per unit? Compare that to the extra price you pay for air freight.
Ocean LCL is the go-to mode for most FBA sellers importing from China. For shipments between 1 and 15 CBM, LCL gives the best cost per unit, with transit times of 25–40 days port-to-port. Ocean FCL makes more sense above 15 CBM, where the per-CBM rate drops a lot versus LCL. For a full comparison of LCL vs FCL cost limits, see our LCL shipping rates guide.
Air freight costs 4–6x more than ocean per chargeable kilogram, but it delivers in 5–10 days airport-to-door. It makes sense for FBA in a few cases. First, high-value SKUs, where cash tied up in ocean transit costs you money. Second, time-sensitive restocks, where a stockout means lost BSR (Best Seller Rank). Third, small first-test shipments (under 50 kg), where speed-to-market beats per-unit cost.
| Mode | Transit Time (China to US FC) | Cost Range (2026, Q1) | Best For |
|---|---|---|---|
| Ocean LCL | 30–42 days | $80–$180/CBM + fees | 1–15 CBM, cost-sensitive |
| Ocean FCL 20ft | 28–38 days | $1,800–$3,500/container | 15–28 CBM, regular volume |
| Ocean FCL 40ft | 28–38 days | $2,800–$5,000/container | 28+ CBM, high-volume sellers |
| Air express | 5–8 days | $5–$10/kg | High-value, time-critical restocks |
| Sea-air hybrid | 18–22 days | $2–$4/kg | Middle ground for seasonal launches |
Customs Clearance for FBA US Shipments
Every FBA shipment entering the US falls under US Customs and Border Protection (CBP) oversight. The process follows the same steps as any commercial import. But FBA sellers face two extra hurdles. First, they are often the importer of record for the first time. Second, they must time their clearance so cargo reaches the FC before stock runs out.
ISF (Importer Security Filing) is the first key step. You or your freight forwarder must file the ISF online through CBP's ACE system, at least 24 hours before the vessel leaves the origin port. ISF holds 10 data points, including the seller, buyer, importer of record, ship-to party, and HS codes. A late or wrong ISF triggers a $5,000 fine and can get your cargo held at the port.
After the vessel arrives, your customs broker partner files the formal entry (CF-7501 or equivalent) with CBP. They work out and pay the import duty, Merchandise Processing Fee (MPF), and Harbor Maintenance Fee (HMF). For Chinese-origin goods in 2026, expect Section 301 tariffs of 7.5–25% or higher on top of the standard MFN duty rate — the exact figure depends on your product's HTS code.

Required Documents for FBA US Inbound
Missing even one document can stop your cargo at the port, or cause Amazon to refuse the delivery. Prepare and check each of these before your shipment leaves.
- Commercial Invoice: Correct value, HS codes, country of origin, and buyer/seller info. CBP checks this against your ISF filing — any mismatch triggers a hold.
- Packing List: Carton count, net and gross weights, dimensions, SKU breakdown. Amazon's receiving team uses this to check against your shipment plan.
- Bill of Lading (B/L) or Airway Bill (AWB): The contract of carriage. For ocean, the B/L is the title document — you need the original or a telex release to claim your cargo.
- Amazon FBA Shipment ID Labels: Made in Seller Central, applied to each carton. The format must match Amazon's barcode rules exactly.
- ISF Filing Confirmation: Proof that ISF was filed on time. Your forwarder gives you this.
- CBP Import Bond: A single-entry bond for one-off shipments, or a continuous bond for regular importers. Required for all commercial entries over $2,500.
- Certificate of Origin: Required when you claim FTA preferential duty rates. Also confirms country of origin for the Section 301 tariff check.
Common FBA US Shipping Mistakes
These mistakes cause most of the FC refusals, customs delays, and costs that FBA sellers could avoid when importing into the US.
- Wrong or missing Amazon shipment ID labels: FCs scan every carton. A missing or wrong shipment ID label means the receiving team cannot find your shipment plan, and they will refuse the delivery.
- Shipment plan mismatch: The actual units in the cartons don't match what was entered in Seller Central. Even one extra unit triggers a discrepancy review.
- Pallet height violations: Amazon requires pallets to be 72 inches or under (stacked and shrink-wrapped). Overheight pallets are refused at the dock.
- Filing ISF late: ISF must be filed 24 hours before vessel departure, not 24 hours before US arrival. Late filing means a $5,000 CBP fine.
- Understating commercial invoice value: CBP checks declared values against market prices. Penalties for undervaluing goods range from double the underpaid duty, up to full seizure of your goods.
- Not booking a delivery appointment: Amazon FCs do not accept walk-in deliveries. No appointment means the truck is turned away and you pay re-delivery charges.
- Skipping required prep work: Amazon requires poly bags, bubble wrap, or suffocation warning labels on certain products before they reach the FC. Skip this step at origin, and you will need to pay a US-based prep service — which adds cost and delay to your inbound.
- Ignoring your Inventory Performance Index (IPI) score: A low IPI score can trigger storage limits that block you from even creating a shipment plan. Check your IPI score in Seller Central before you place a large purchase order.
