Master FOB China Shipping: Essential Tips for Importers

FOB (Free on Board) is the most commonly used Incoterm for imports from China. Under FOB terms, your Chinese supplier handles everything up to and including loading your goods onto the vessel at the named Chinese port. Once the cargo is on board, all costs and risks transfer to you: ocean freight, insurance, destination port charges, customs clearance, duties, and final delivery.

Approximately 70% of China’s exports ship under FOB terms. The reason is straightforward: FOB gives you, the buyer, control over the most expensive variable in international shipping — the ocean freight — while keeping the supplier responsible for the China-side logistics they know best.

But FOB is also where new importers make their most expensive mistakes. Writing “FOB China” in a contract instead of naming a specific port, failing to calculate the full landed cost beyond the FOB price, not understanding when risk actually transfers, and missing hidden charges like demurrage and detention can each cost hundreds to thousands of dollars per shipment.

This guide covers how FOB actually works in practice, how it compares to CIF and EXW, the correct way to specify FOB terms in contracts, a complete landed cost calculation example, the specific ports to know, and the cost traps to avoid.

What FOB Means in Practice

Under FOB terms (Incoterms 2020), the seller is responsible for:

• Manufacturing and export packaging
• Inland transportation from factory to the named port
• Export customs clearance in China
• Loading goods onto the vessel at the port of origin
• All costs and risks up to the point the goods are on board

The buyer is responsible for:

• Ocean freight from the Chinese port to the destination port
• Marine cargo insurance (optional but strongly recommended)
• Destination port charges (terminal handling, unloading)
• Import customs clearance
• Import duties and taxes
• Inland transportation from destination port to warehouse/final address

The Critical Detail: “FOB China” Is Not a Valid Incoterm

This is one of the most common mistakes in Chinese trade contracts. A contract that states “FOB China” is legally ambiguous because it does not name a specific port. The correct format is:

FOB Shanghai or FOB Ningbo or FOB Shenzhen (Yantian)

The named port matters because your supplier’s inland transportation cost (factory to port) varies significantly depending on which port you specify. A supplier in Dongguan trucking to Shenzhen/Yantian port (30-60 minutes) faces a fraction of the cost of trucking to Shanghai (1,200+ km). If the contract says “FOB China” without a port name, the supplier can choose whichever port is most convenient for them, which may not be the cheapest or fastest option for you.

Always specify the exact port in your purchase order and contract.

FOB vs FCA: The Technical Distinction Most Importers Miss

Incoterms 2020 officially recommends FCA (Free Carrier) over FOB for containerized cargo. The reason: under FOB, risk transfers when goods pass the ship’s rail. But containers are typically delivered to the port terminal days before the vessel arrives. During that waiting period, the goods are in a legal gray zone — they have left the seller’s control but have not yet crossed the ship’s rail.

FCA solves this by transferring risk when the goods are handed over to the carrier at the terminal, which is the actual physical handover point for containerized shipments.

In practice, nearly every Chinese supplier still uses FOB rather than FCA. The industry convention is deeply entrenched. If you want FCA terms, you will need to explain the distinction to your supplier and potentially negotiate it explicitly. For most importers, FOB works fine in practice, but you should be aware that the 1-3 day gap between terminal delivery and vessel loading represents a period where neither party’s insurance may clearly cover the goods.

FOB vs CIF vs EXW: Which Should You Use?

FOB: The Recommended Default

FOB is the right choice for most importers because it gives you control over the ocean freight (where significant cost savings are possible through your own freight forwarder) while keeping the supplier responsible for China-side logistics (trucking, export customs, loading) that they handle routinely.

You control: Freight forwarder selection, shipping route, carrier, schedule, insurance. This means you can negotiate ocean freight rates independently, compare quotes from multiple forwarders, and avoid paying supplier markups on shipping.

CIF: The Convenience Trap

CIF (Cost, Insurance, Freight) means the supplier handles everything up to arrival at your destination port, including ocean freight and basic insurance. It sounds simpler: one price, fewer things to manage.

The problem: when a supplier quotes CIF, they bundle their freight forwarder’s charges into your price — and that bundled rate is typically 20-40% above the actual market freight rate. The supplier’s forwarder gives the supplier a rebate or commission on your shipping cost. You have no visibility into what the freight actually costs.

Under CIF, the supplier also controls the shipping schedule, carrier selection, and routing. You may end up on a slower vessel or routed through an extra transshipment port because it is cheaper for the supplier’s forwarder.

Additionally, under CIF, the supplier’s forwarder issues the Bill of Lading. This means the supplier maintains document control over your cargo until they release the B/L to you. Under FOB, your forwarder issues the B/L, and you have document control from the moment the cargo loads.

FreightAmigo’s 2025 operational data shows that CIF shipments from China to Southeast Asia averaged 25% higher total costs than FOB equivalents.

When CIF makes sense: Only when you have no freight forwarder relationship, no logistics experience, and are shipping a very small order where the convenience outweighs the markup. Even then, the long-term answer is to develop a freight forwarder relationship and switch to FOB.

EXW: Maximum Risk, Lowest Base Price

EXW (Ex Works) means the supplier’s job is done the moment goods are packed and sitting at their factory. Everything after that is your responsibility: trucking to the port (in China), export customs clearance (requires a licensed Chinese customs broker), loading, ocean freight, insurance, import clearance, and delivery.

The EXW base price is the lowest because the supplier does the least. But the savings are often illusory. Union Source, with 20+ years of China sourcing experience, reports that after adding China-side trucking, export brokerage, and loading fees, EXW’s actual landed cost is often within 5-10% of FOB — while requiring significantly more work and risk on the buyer’s side.

When EXW makes sense: Only when you have your own warehouse or consolidation facility in China, you are combining shipments from multiple suppliers, or you need to inspect and relabel goods at a Chinese warehouse before export. Otherwise, FOB is simpler, safer, and not significantly more expensive.

China’s Major FOB Shipping Ports

Shanghai (Yangshan / Waigaoqiao)

The world’s busiest container port. Handles roughly 49 million TEU annually. Best for: suppliers in the Yangtze River Delta (Zhejiang, Jiangsu, Anhui, Shanghai proper). Most shipping lines have direct services from Shanghai to all major global destinations.

Ningbo-Zhoushan

China’s second-busiest port, handling over 35 million TEU. Located south of Shanghai in Zhejiang Province. Best for: suppliers in Zhejiang (Yiwu, Wenzhou, Hangzhou, Cixi). Often slightly lower port charges than Shanghai.

Shenzhen (Yantian / Shekou / Chiwan)

The primary port complex for the Pearl River Delta manufacturing hub. Best for: suppliers in Guangdong (Dongguan, Shenzhen, Huizhou, eastern Guangdong). Yantian is the largest terminal and handles the majority of US-bound cargo from southern China.

Guangzhou (Nansha)

Serves the western Pearl River Delta. Best for: suppliers in Foshan, Zhongshan, Jiangmen, and western Guangdong. Growing capacity but fewer direct services than Shenzhen for US routes.

Xiamen

Serves Fujian Province manufacturers. Best for: suppliers in Fujian (shoe factories, stone/ceramic, tea). Smaller than Shanghai or Shenzhen but efficient for regional cargo.

Qingdao

Northern China’s primary port. Best for: suppliers in Shandong Province (tires, electronics, machinery, textiles). Direct services to US East Coast and Europe.

Port selection tip: The FOB port should be the one closest to your supplier’s factory. The difference in inland trucking cost between using the nearest port and using a distant one can range from $50 to $480 per container. Always ask your supplier which port they normally ship from before specifying the FOB port in your contract.

Landed Cost Calculation: A Worked Example

Your FOB price is not your product cost. Your landed cost is. Here is a realistic example for a US importer:

Scenario: 1,000 units of consumer electronics, FOB Shenzhen (Yantian). FOB unit price: $8.00. Total FOB value: $8,000. Shipping via 20ft FCL to Los Angeles.

The FOB price per unit is $8.00. The landed cost per unit is $13.58. The difference — $5.58 per unit — is the cost of getting the product from the Chinese port to your warehouse, including duties. If you priced your product based on the $8.00 FOB figure without calculating landed cost, your margins would be 41% lower than expected.

Key takeaway: Always calculate landed cost before setting your retail price or evaluating supplier quotes. A supplier quoting $7.50 FOB on a product with 25% Section 301 tariff will have a higher landed cost than a supplier quoting $8.50 FOB on a product in a tariff-free category.

Hidden Costs That Catch New Importers

Demurrage and Detention

Demurrage: A charge for leaving your container at the port terminal beyond the free time period (typically 5-7 days). Rate: approximately $100-200 per day per container, escalating after the first week.

Detention: A charge for keeping the shipping line’s container at your warehouse beyond the free time after pickup. Rate: similar to demurrage.

These charges accumulate quickly if customs clearance is delayed, documentation is incorrect, or you are slow to arrange pickup. On a single shipment, demurrage/detention can easily add $500-$2,000 if you are not prepared.

Prevention: Have your customs broker and freight forwarder ready before the vessel arrives. Pre-file your customs entry. Arrange inland trucking in advance. Know your free time allowance and track it.

Container Inspection Fees

US Customs and Border Protection (CBP) may randomly select your container for physical examination. If your container is inspected, you pay the examination fee ($100-300+), the trucking to and from the examination site, and potential demurrage while the container is held.

Peak Season Surcharges

Ocean freight rates spike during peak shipping season (typically August-October for US-bound cargo, ahead of holiday retail). Rates can increase 30-100% above off-peak levels. Plan shipments to avoid peak season when possible, or lock in rates with your freight forwarder in advance.

Documentation Amendment Fees

If your Bill of Lading, commercial invoice, or packing list contains errors that need correction after the vessel sails, shipping lines charge amendment fees ($50-150 per correction). Getting documentation right the first time saves money and prevents delays.

Insurance: What FOB Buyers Need to Know

Under FOB, cargo insurance is the buyer’s responsibility from the moment goods load onto the vessel. Basic carrier liability provides minimal coverage (typically $500 per package or $2 per kg, whichever is greater — far below the actual value of most shipments).

Marine cargo insurance typically costs 0.3-1.5% of the insured value (CIF value x 110%), depending on the product category and route. For a $10,000 shipment, that is $33-$165 for coverage that protects against total loss, partial loss, damage, and general average contribution.

Do not skip insurance to save $100. A single container loss or damage incident without insurance can cost $10,000-$50,000+. The math overwhelmingly favors buying coverage on every shipment.

Quality Control at the FOB Point

The FOB loading point is your last opportunity to verify product quality before risk transfers to you. Once goods are on the vessel, they are your problem regardless of condition.

Pre-shipment inspection: Hire a third-party inspection company (QIMA, SGS, Bureau Veritas, Asia Quality Focus) to inspect finished goods at the factory before they ship to the port. Cost: $150-400 per inspection. This investment is trivial compared to the cost of receiving a container of defective goods.

Container loading supervision: Have an inspector present during container loading to verify correct products and quantities are loaded, packaging is intact, the container is clean and undamaged, and goods are properly secured. Photograph the container seal number and match it to shipping documents.

Documentation Checklist for FOB Shipments

Your supplier provides:

• Commercial Invoice (product descriptions, quantities, values, FOB price, HS codes)
• Packing List (carton count, dimensions, weights, contents per carton)
• Bill of Lading (proof of shipment, issued by the carrier or your forwarder)
• Certificate of Origin (if required for preferential duty rates)
• Any product-specific certificates (CE, FCC, FDA, test reports)

You need for import clearance:

• All of the above documents from your supplier
• ISF (Importer Security Filing) — must be filed at least 24 hours before vessel loading for US-bound shipments
• Customs entry filing (handled by your customs broker)
• Customs bond (required for US imports; can be single-entry or continuous)
• Product-specific compliance documentation (CPSC, FDA, EPA as applicable)

Errors or delays in any of these documents can hold your container at the port and trigger demurrage charges. Have your customs broker review documentation before the vessel sails, not after it arrives.

Conclusion

FOB is the right Incoterm for most China imports because it gives you control over the shipping process while keeping your Chinese supplier responsible for the logistics they handle best. But using FOB effectively requires more than writing “FOB” on a purchase order.

Specify the exact port name (FOB Shenzhen, not FOB China). Calculate your full landed cost including freight, duties, insurance, and destination charges before evaluating any supplier quote. Buy marine cargo insurance on every shipment. Inspect goods before they load. Pre-file customs documentation. And build a relationship with a reliable freight forwarder who understands China trade routes and can help you navigate rate volatility, peak season surcharges, and documentation requirements.

The difference between a profitable import operation and a money-losing one is rarely the FOB price. It is the $3-$8 per unit in post-FOB costs that many importers fail to plan for.
