Shipping to Amazon FBA in the USA: 2026 Guide for Importers
Shipping to an Amazon fulfillment center in the US is not like shipping to a warehouse. Amazon has strict receiving rules — wrong labels, missed appointments, and pallet errors mean refusals. This guide walks you through the full inbound process so your inventory lands in FBA stock without a hiccup.
Amazon US Fulfillment Center Network Overview
Amazon's US fulfillment center network is one of the largest logistics infrastructures in the world. In 2026, it spans over 100 active FCs across the continental US, plus sortation centers, delivery stations, and air hubs. The network is divided 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 last-mile delivery.
When you create a shipping plan in Seller Central, Amazon's algorithm assigns your inventory to one or more FCs based on your product category, historical demand patterns, and current network balance. You will typically be assigned 1–3 destination FCs per shipment plan. If Amazon splits your shipment into multiple FCs and you want to minimize that, Amazon's Inventory Placement Service allows you to send all units to a single destination for a fee (per-unit surcharge applies).
Understanding which FC Amazon assigns helps you plan your port of entry and trucking route. An FC in New Jersey draws most of its inventory through ports on the East Coast (New York-New Jersey, Baltimore, Norfolk). An FC in Texas or the Southeast can be serviced from either Gulf Coast ports or East Coast ports. An FC in California, Nevada, or Arizona is typically fastest via West Coast ports (Los Angeles, Long Beach).
East Coast vs. West Coast Port Entry
The choice between entering the US through a West Coast or East Coast port affects your total transit time, freight cost, and risk exposure. Both options are viable for FBA inbound — the right choice depends on your supplier location, the assigned FC, and the current congestion situation at each port.
- LA/Long Beach (West Coast): Largest US port complex. Direct services from China, Vietnam, South Korea, Japan. 20–28 days from South China ports. Best for FCs in CA, NV, AZ, WA. Periodic congestion in peak season (Q4) can add 3–7 days.
- Savannah / Charleston (East Coast Southeast): Fastest-growing US port corridor. Direct services from China via Panama Canal. 30–38 days from South China ports. Best for FCs in GA, FL, NC, SC, TN. Lower congestion than LA, growing container capacity.
- New York / New Jersey (East Coast Northeast): Major gateway for Northeast FCs. 35–45 days from China. Best for FCs in NJ, PA, NY, CT, MA. High terminal costs but strong infrastructure for LCL consolidation.
Ocean vs. Air Freight for FBA US Inbound
The mode decision for FBA inbound is fundamentally an economics question: how much is 30 days of faster delivery worth per unit, compared to the premium you pay for air freight?
Ocean LCL is the default mode for most FBA sellers importing from China. For shipments between 1 and 15 CBM, LCL offers the best cost-per-unit with transit times of 25–40 days port-to-port. Ocean FCL makes sense above 15 CBM, where the per-CBM rate drops significantly versus LCL. For a detailed comparison of LCL vs FCL cost thresholds, see our <a href='/insights/lcl-shipping-rates/'>LCL shipping rates guide</a>.
Air freight costs 4–6x more than ocean per chargeable kilogram, but delivers in 5–10 days airport-to-door. It makes sense for FBA in specific cases: high-value SKUs where capital tied up in ocean transit is expensive, time-sensitive restocks where a stockout means lost BSR (Best Seller Rank), or small initial test shipments (under 50 kg) where speed-to-market matters more than 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 is subject to US Customs and Border Protection (CBP) oversight. The process follows the same steps as any commercial import — but FBA sellers face two extra complications: they are often the importer of record for the first time, and they must time their clearance so that cargo reaches the FC before their inventory runs out.
ISF (Importer Security Filing) is the first critical step. You or your freight forwarder must file the ISF electronically through CBP's ACE system at least 24 hours before the vessel departs the origin port. ISF contains 10 data elements including the seller, buyer, importer of record, ship-to party, and HS codes. A late or incorrect ISF triggers a $5,000 fine and can cause your cargo to be held at the port.
After the vessel arrives, your customs broker partner files the formal entry (CF-7501 or equivalent) with CBP. They calculate 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, depending on your product's HTS code.

Required Documents for FBA US Inbound
Missing a single document can stop your cargo at the port or cause Amazon to refuse the delivery. Prepare and verify each of these before your shipment departs.
- Commercial Invoice: Accurate value, HS codes, country of origin, buyer/seller details. CBP compares this against your ISF filing — mismatches trigger holds.
- Packing List: Carton count, net and gross weights, dimensions, SKU breakdown. Amazon's receiving team uses this to verify 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: Generated in Seller Central, applied to each carton. Format must match Amazon's barcode specifications exactly.
- ISF Filing Confirmation: Proof that ISF was filed on time. Your forwarder provides this.
- CBP Import Bond: Single-entry bond for one-off shipments, or continuous bond for regular importers. Required for all commercial entries over $2,500.
- Certificate of Origin: Required when claiming FTA preferential duty rates. Also confirms country of origin for Section 301 tariff assessment.
Common FBA US Shipping Mistakes
These errors account for the majority of FC refusals, customs delays, and avoidable costs that FBA sellers face when importing into the US.
- Wrong or missing Amazon shipment ID labels: FCs scan every carton. A missing or incorrect shipment ID label means the receiving team cannot locate your shipment plan and 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 audits declared values against market benchmarks. Undervaluation penalties range from double the underpaid duty to seizure of 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.
Shipping to Amazon FBA USA FAQ
How long does it take to ship to Amazon FBA from China?
Total door-to-FC time from China typically runs 35–50 days by ocean: 3–5 days for cargo pickup and export clearance, 20–35 days ocean transit (West Coast) or 30–42 days (East Coast), 1–3 days US customs clearance, and 1–3 days port-to-FC trucking. Air freight cuts this to 8–14 days total, at 4–6x higher cost. Plan your replenishment orders to have 60+ days of buffer against your reorder point.
Do I choose which Amazon FC my inventory goes to?
No. Amazon's algorithm assigns FCs when you create a shipping plan in Seller Central. You can use Amazon's Inventory Placement Service to consolidate into fewer FCs for a per-unit fee. Your forwarder needs the FC address from your Seller Central shipping plan before booking the trucking leg.
Can I ship to an Amazon FC without a freight forwarder?
Technically yes — you can file your own ISF and customs entry, book your own ocean freight, and arrange your own dray. In practice, most sellers find that the customs and compliance requirements make DIY importing risky without prior experience. A single $5,000 ISF fine exceeds what most FBA sellers save by self-booking.
What is an ISF filing and when is it due?
ISF (Importer Security Filing) is a US CBP requirement for all ocean imports. It must be filed electronically at least 24 hours before the vessel departs the origin port — not before US arrival. ISF contains 10 data elements: seller, buyer, importer of record, consignee, manufacturer, ship-to party, country of origin, HS codes, and container/seal number. Your freight forwarder files ISF on your behalf as part of the customs clearance process.
What customs duties apply to Amazon FBA shipments from China?
For Chinese-origin goods entering the US in 2026, duties include: (1) base MFN import duty by HTS code (varies 0–25%+), (2) Section 301 tariffs specific to China-origin goods (7.5–145% depending on the product list), (3) MPF (Merchandise Processing Fee) of 0.3464% of the declared value (minimum $32, maximum $614), and (4) HMF (Harbor Maintenance Fee) of 0.125% on ocean shipments. Your total duty burden varies significantly by product category — consult your customs broker partner for HTS-specific estimates.
How does Amazon's Carrier Central appointment system work?
Carrier Central is Amazon's portal for scheduling delivery appointments at FCs. Your trucking carrier must create an account in Carrier Central, use the shipment ID from your Seller Central plan to book a time slot, and arrive at the FC within the appointment window. Most FCs require 24–72 hours advance notice for appointments. Your freight forwarder coordinates this booking with the dray carrier as part of the last-mile delivery service.
What happens if my FBA shipment is refused at the FC?
If Amazon refuses your delivery (wrong shipment ID, pallet non-compliance, appointment mismatch), the carrier returns the cargo. You pay for the return freight. You then need to rebook an appointment or reroute to a prep center to fix the issue before re-delivering. Prevention is cheaper: your forwarder should validate your shipment plan, carton labels, and pallet config before the truck leaves the port.
Should I use Amazon's Partnered Carrier Program (PCP) for FBA inbound?
Amazon's PCP offers discounted US domestic trucking rates from a small number of approved carrier partners. It works well for domestic US moves (e.g., from a prep center to an FC). For international inbound from China, PCP does not cover the ocean freight or customs clearance legs — you still need a freight forwarder for those. Many sellers use a forwarder for the ocean-to-port leg and PCP for the domestic portion when the FC is served by an eligible PCP carrier.
