How to Calculate the True Landed Cost of Importing from China
A buyer compares two suppliers. One quotes $4.20 a unit from Ningbo. The other quotes $4.45 from Shenzhen. The Ningbo price wins, the order is placed, and four months later the margin on the product has vanished. Part of the answer sits in who you are actually buying from, which is the difference between an agent, a trader and a factory.
Landed cost is what you actually pay to get one sellable unit into your warehouse. It includes at least eleven line items, and the ones buyers forget are consistently larger than the ones they compare.
The full cost stack
Work through these in order. Each one applies to a real shipment.
- Ex-factory unit price multiplied by quantity. The number every buyer looks at first.
- Tooling and moulds, one-off, from a few hundred dollars for a simple injection mould to $20,000 or more for precision parts.
- Sampling and courier, usually $50 to $200 per round across two or three rounds.
- Domestic transport in China from factory to port, $300 to $900 for a 40-foot container depending on distance.
- Export documentation and customs clearance in China, $150 to $400.
- Freight, sea, air or rail. The largest variable line on the sheet.
- Insurance, around 0.3% to 0.5% of the cargo value, and worth taking on anything you cannot afford to lose.
- Import duty at the destination rate for your product’s classification.
- Value added tax or GST, recoverable in some jurisdictions and a real cost in others.
- Customs brokerage and entry fees, $100 to $250 per entry, plus bond costs in the US.
- Port charges, inland delivery and warehousing, frequently $800 to $1,800 on a container before it reaches your door.
Payment fees deserve their own mention. A bank wire costs $25 to $50 plus a currency spread of 1% to 3%. On a $40,000 order, a 2% spread is $800 that never appears on any quotation.
A worked example, line by line
8,000 stainless steel tumblers, ex-factory $5.35, shipped FOB Ningbo to Los Angeles.
| Line item | Calculation | Amount |
|---|---|---|
| Goods ex-factory | 8,000 × $5.35 | $42,800 |
| Tooling for the custom lid | One-off | $3,200 |
| Sampling and courier | 2 rounds | $360 |
| Domestic transport to port | Factory to Ningbo | $420 |
| Export clearance and documents | Per shipment | $280 |
| Ocean freight, 40ft to LA | Current market rate | $3,400 |
| Marine insurance | 0.4% of goods value | $171 |
| Import duty | HTS classification, 3.4% of value | $1,455 |
| Section 301 additional duty | China origin, 7.5% of value | $3,210 |
| Merchandise Processing Fee | 0.3464%, capped | $148 |
| Harbor Maintenance Fee | 0.125% of value | $54 |
| Customs brokerage and bond | Entry plus continuous bond share | $310 |
| Port, drayage, inland delivery | LA to a Texas warehouse | $1,650 |
| Bank wire and FX spread | ~2% on two payments | $860 |
| Total landed | $58,318 | |
| Landed cost per unit | $58,318 ÷ 8,000 | $7.29 |
The ex-factory price was $5.35. The unit that arrives in Texas costs $7.29. Everything the buyer compared during sourcing related to 73% of the real cost, and the 27% they did not compare is where the margin went.
Where the comparison actually fails
The Ningbo supplier at $4.20 against the Shenzhen supplier at $4.45 looks like a $0.25 advantage, which is $2,000 on 8,000 units. Then the details arrive.
Ningbo ships out of a port with a longer inland haul and a less frequent sailing schedule, so transit runs four days longer and demurrage risk rises. The lower price assumes a thinner wall, which pushes the unit into a different HTS subheading with a higher duty rate. The Shenzhen price includes a lid mould that Ningbo bills separately at $3,200.
Net, the more expensive quotation is $2,900 cheaper on the first order, and the gap widens on repeat orders where the tooling no longer applies.
This is why comparing ex-factory prices across suppliers is close to meaningless unless the specification and the Incoterm match. A price quoted FOB and a price quoted EXW differ by the inland haul and the export clearance, which is $500 to $1,300 on a container. Comparing them directly is comparing two different products.
Incoterms change the number, not the cost
The Incoterm decides who pays each line, not how much the total is. A CIF quote looks higher than an FOB quote for identical goods because freight and insurance have been folded in. Buyers who choose on headline price alone frequently pick the FOB number and then pay the freight separately at a worse rate than the supplier could have obtained.
The one thing Incoterms genuinely change is risk. Under FOB, your exposure begins when the goods are on board. Under CIF, the supplier arranges insurance, and the cover they buy is usually the minimum the contract allows rather than what your goods are actually worth.
The four mistakes that move the number most
Using the wrong HTS code. Classification decides duty, and two codes that describe similar products can differ by 8 percentage points. On a $50,000 shipment that is $4,000. Get a written classification opinion from your broker before the goods ship, not after the entry is filed.
Ignoring the duty stack. Base duty is one layer. Section 301 on China-origin goods, anti-dumping orders on specific categories, and quota costs sit on top. A product with a 3% base rate can carry 12% or more once the additional duties apply.
Forgetting that VAT is cash flow, not always a cost. In the EU, import VAT is recoverable for VAT-registered businesses, which makes it a working capital problem rather than a margin problem. In markets where it is not recoverable, it belongs in the unit cost. Getting this wrong distorts the entire pricing model.
Budgeting first-order costs as if they repeat. Tooling, sampling, mould trials and the initial compliance testing are one-off. On the tumbler example, $3,560 of the $58,318 disappears from the second order, which lowers the repeat landed cost to roughly $6.85 a unit. Buyers who price their first order as the steady state over-price and lose the sale, or under-price and lose the margin.
Frequently asked questions
What is a normal landed cost markup over the ex-factory price?
For a mid-value consumer good shipped by sea from China to the US or EU, landed cost runs 25% to 45% above the ex-factory price before VAT. Air freight pushes that above 100% on heavy goods. The percentage is driven almost entirely by the freight-to-value ratio, which is why light, high-value products tolerate air and heavy, low-value products do not.
Should I compare suppliers on FOB or landed cost?
Write your own landed cost model and plug each supplier’s figures into it. Comparing supplier quotations is unreliable because suppliers quote different Incoterms, different specifications and different assumptions about who pays the inland haul. One spreadsheet, applied consistently to every quote, is what makes the comparison real.
How much does sea freight from China cost?
A 40-foot container from a Chinese port to the US West Coast has ranged from under $1,500 to over $20,000 in the last five years. Rates move weekly and spike during peak season, from August through October, and around Chinese New Year. Ask for a rate valid for 30 days and budget a 20% contingency on any shipment more than a month out.
Are there fees nobody warns me about?
Four appear repeatedly: demurrage and detention when a container sits at port beyond its free days, chassis and chassis split fees at US ports, destination terminal handling that is not included in the freight quote, and warehouse receiving fees that Amazon FBA charges per carton. Together these run $500 to $2,000 on a first shipment and almost never appear on the supplier’s quotation.
