The Overall Workflow: From Factory to Amazon Warehouse

Sending products from a supplier in China to an Amazon FBA warehouse involves several tightly connected steps. It is not a single shipping transaction but a sequence where each stage must meet Amazon’s requirements. The typical flow looks like this:

Complete manufacturing and quality inspection at the factory.
Prepare each unit according to FBA prep rules (labels, packaging, poly bags).
Pack units into shipping cartons that follow Amazon’s weight and size limits.
Create a shipment plan in Seller Central and print all required labels.
Arrange freight with a forwarder—choose air freight, sea freight, or express consolidation.
Ship to the destination country and clear customs.
Deliver to the assigned Amazon fulfillment center, often with a scheduled delivery appointment.
Amazon receives, scans, and makes your inventory available for sale.

Each link in this chain can cause delays or extra costs if not handled correctly. The rest of this guide breaks down the critical areas where sellers often need the most help.

Preparing Your Products for Amazon FBA: Labeling and Barcodes

Amazon requires every unit sent to FBA to be properly labeled and prepped. These rules exist to protect products during storage and picking, and to ensure accurate inventory tracking.

Essential FBA Labeling Rules

Every sellable unit must have a scannable FNSKU barcode. This can be applied by the manufacturer, a prep center, or the seller.
Use a thermal or laser printer and ensure the barcode is clear, not smeared, and not placed over a seam or curved surface.
Cover or remove any original manufacturer barcodes (UPC, EAN) if they differ from the FNSKU. Only the FNSKU should be visible.
For products that come in sets or bundles, the outer packaging must have a single FNSKU, and the whole set must be sealed as one unit.
Poly bags used for loose items must be transparent, have a suffocation warning label (if the opening is 5 inches or larger), and be at least 1.5 mil thick.
Fragile items need protective packaging such as bubble wrap or foam. Amazon may refuse units that arrive damaged due to poor prep.

Many sellers based outside the US choose to use an Amazon FBA prep service in China. These providers inspect, label, and pack goods before shipping, which can reduce the chance of receiving a prep violation at the fulfillment center.

Carton Requirements: Weight, Dimensions, and Labeling

Amazon has strict rules for the shipping cartons that arrive at their warehouses. Overlooking these will often lead to refusal, return, or unexpected charges.

Key Carton Rules

Rule	Requirement
Maximum carton weight	50 lb (23 kg) unless marked “Heavy Package.” If one carton exceeds 50 lb, a “Team Lift” label is required. No single carton may exceed 150 lb.
Carton dimensions	No side longer than 25 inches (63.5 cm) for standard shipments, unless arranged as a pallet delivery.
Pallet requirements	For LTL and FTL shipments, pallets must measure 40 x 48 inches, be in good condition, and use GMA Grade B or higher. Total pallet height including the pallet must not exceed 72 inches.
Carton content labels	Every carton must have an Amazon shipment label (generated in Seller Central). The FBA carton ID barcode is scanned upon receiving.
Dunnage	Use appropriate void fill so products do not shift. Do not use shredded paper, packing peanuts, or crinkle cut paper, as these cause messes and may be rejected.

When shipping from China, freight forwarders often repack or consolidate cartons to reduce volume. Ensure they understand and follow these requirements; otherwise, the shipment could be turned away at the warehouse.

Consolidation and Shipping Methods: Air Freight, Sea Freight, and Express

Choosing how to move your goods from China to Amazon FBA is a balance of speed, cost, and inventory predictability. The table below compares the main methods used by sellers.

Method	Typical Transit Time	Cost Level	Best For
Express (DHL, UPS, FedEx)	3–7 days	Highest per kg	Small, lightweight, high-value shipments; urgent restocks
Air Freight (consolidated)	7–12 days	Moderate	Medium-sized shipments where speed matters more than ocean cost savings
Sea Freight (LCL)	25–40 days	Low per unit	Larger volumes that do not fill a container; cost-effective for moderate weight
Sea Freight (FCL)	25–40 days	Lowest per unit for high volume	Full container loads; highest volume shipments; economies of scale

Many sellers start with express or air freight for their first shipment to test the market, then switch to ocean freight as sales volume grows. Freight forwarders can combine several sellers’ goods into one container (LCL consolidation), which is common for shipping from China to Amazon FBA in the US.

Amazon FBA Fees: What Costs Are Included and How to Estimate

It is a common misunderstanding that FBA shipping fees include the cost of moving goods from China to Amazon. Amazon’s FBA fees cover only warehousing and customer fulfillment activities inside Amazon’s network. The freight cost from your supplier to the fulfillment center—often called “inbound shipping”—is separate and paid by you.

Core FBA fees to expect:

Fulfillment Fee: Charged per unit when an order is picked, packed, and shipped to the customer. Based on product size and weight.
Monthly Storage Fee: Charged per cubic foot for inventory stored in Amazon’s warehouse. Rates rise during Q4.
Long-Term Storage Fee: Applied to units held for more than 365 days.
Removal or Disposal Fee: Charged if you ask Amazon to return or discard unsellable inventory.

To estimate the total landed cost from China, add your product cost, freight from China to Amazon, customs duties, and Amazon FBA fees together. Use Amazon’s Revenue Calculator in Seller Central to preview FBA fees per ASIN before shipping.

Delivery Appointments and Carrier Requirements

Amazon’s fulfillment centers operate on a strict inbound appointment system. For Less Than Truckload (LTL) and Full Truckload (FTL) deliveries, the carrier must schedule a delivery appointment in advance. Without a confirmed appointment, the truck may be turned away at the dock.

Key appointment rules:

Appointments are scheduled through Amazon’s Carrier Central platform or via an Amazon Partnered Carrier.
Required information includes the shipment ID, Amazon Reference Number, number of pallets, freight class, and total weight.
The carrier must arrive during the appointment window. Late arrivals or early drop-offs can lead to refusal.
Small parcel deliveries (UPS, FedEx) do not normally require appointments, but the shipment must still conform to the shipping plan created in Seller Central.

When using a freight forwarder from China, confirm they are familiar with Amazon’s delivery requirements for the destination country. A forwarder that regularly handles Amazon FBA shipments will understand how to manage the appointment process.

Compliance Risks and How to Avoid Shipment Refusal

Amazon’s receiving standards are enforced consistently, and non-compliance can lead to shipment refusal, extra charges, or even suspension of your shipping privileges. Here are the most frequent compliance pitfalls:

Labels not scannable: Barcode smudging, poor print quality, or placing labels over edges cause receiving errors.
Overweight cartons: Cartons over 50 lb without “Team Lift” labels are rejected. Any carton over 150 lb will automatically be refused.
Missing FBA shipment IDs: Each carton must have a unique label generated from the shipment plan. Void or duplicate IDs cause inventory discrepancies.
Mismatched shipment plan: Sending items not listed in the plan or exceeding the quantity approved can lead to the entire shipment being turned away.
No delivery appointment: For LTL and FTL, arriving without an appointment results in refusal and possible storage fees at the carrier’s yard.
Poor prep: Units that leak, have sharp edges unprotected, or arrive in flimsy packaging can be classified as “unfulfillable” on arrival.

Before confirming a shipment, always run through Amazon’s “Shipping Queue” checklist in Seller Central. This step-by-step wizard confirms that labeling, prep, and shipping plan details are correct before you finalize.

Shipping from China to Amazon FBA: A Practical Checklist

Use this checklist before you release a shipment from your supplier or prep center.

Create a Fulfillment and Shipment Plan in Seller Central and note the Shipment ID.
Print FNSKU labels for every unit (or ensure the prep center does so).
Verify product prep: poly bags with suffocation warnings, bubble wrap for fragile items, sealed bundles.
Pack units into cartons that meet Amazon’s weight and size limits.
Apply Amazon carton labels (one per carton) and check that they are scannable.
Arrange freight with a forwarder experienced in Amazon FBA shipments from China.
Confirm the delivery appointment if required (LTL/FTL).
Provide the forwarder with all necessary documentation: commercial invoice, packing list, and Amazon shipment labels.
Track the shipment and monitor the “Shipping Queue” for any Amazon warnings.

Following this workflow reduces the risk of refused deliveries and helps you maintain a healthy Inventory Performance Index.

Frequently Asked Questions

What is the cheapest way to ship from China to Amazon FBA?

For larger volumes, ocean freight (LCL or FCL) offers the lowest per-unit cost. Air freight or express is more expensive but faster, often used for restocks or lightweight products.

Do I need a prep service in China for Amazon FBA?

If you are not in China to inspect and label units yourself, an Amazon FBA prep service can save time and prevent receiving errors. These services handle quality checks, FNSKU labeling, and packaging according to Amazon’s rules.

What happens if my carton weight exceeds Amazon’s limit?

Cartons over 50 lb must have a “Team Lift” label. Cartons over 150 lb will be refused at the dock. Overweight cartons without proper labeling may incur extra charges or delay receiving.

Can I ship directly from my factory in China to Amazon FBA without a forwarder?

Yes, but most factories are not familiar with Amazon’s shipping requirements. A freight forwarder experienced with FBA can handle consolidation, customs clearance, and delivery appointments, reducing the risk of shipment refusal.

How long does sea freight take from China to Amazon FBA in the US?

Typical transit time for ocean freight from major Chinese ports to US West Coast fulfillment centers is 25–40 days, including customs clearance and inland delivery. East Coast destinations add roughly 1–2 weeks.

Do Amazon FBA fees include the cost of shipping from China?

No. FBA fees cover warehousing and customer order fulfillment. The cost of transporting goods from your supplier to Amazon’s warehouse is a separate inbound shipping charge that you arrange and pay for.

What is the most common reason Amazon rejects an FBA shipment from China?

The most frequent causes are unreadable FBA carton labels, overweight cartons, missing delivery appointments, and mismatches between the shipment plan and the actual contents. Following the checklist in this article helps avoid these issues.
