Part of the IPS series on turning a product idea into a manufactured reality. Start with the complete manufacturing roadmap.
One of the most common and costly mistakes in product manufacturing is building a business model around the factory price. The factory price – what a manufacturer in China, Vietnam, or Taiwan charges you per unit – is just the starting point. By the time your product arrives in your warehouse, the actual cost per unit can be 40 to 80 percent higher.
Founders who discover this after placing their first production order face an uncomfortable reality: the margin they projected does not exist. Some discover the product cannot be profitably sold at any price their market will accept. This is not a supply chain problem. It is a planning problem – and it is entirely avoidable.
This guide walks through every component of landed cost, how to estimate each one before you commit to production, and how to use landed cost to make smarter decisions about product design, sourcing region, and pricing.
What Is Landed Cost?
Landed cost is the total cost to get one unit of your product from the factory floor to your warehouse – or directly to your customer or retail partner. It includes every expense incurred between the moment the factory finishes making your product and the moment it is ready to sell.
The formula is straightforward:
Landed Cost = Factory Unit Price + Tooling Amortization + Freight + Import Duties + Customs Fees + Insurance + Warehousing and Fulfillment
Each of these components needs to be calculated before you finalize your product design or place any tooling orders. Here is what goes into each one.
Component 1: Factory Unit Price
This is the price the manufacturer charges per unit, based on your order quantity. A few things to understand about factory pricing , connected with landed cost
Price breaks by volume
Factory unit prices drop significantly as order quantities increase. A product that costs $8.00 per unit at 1,000 units might cost $5.50 at 5,000 units and $4.00 at 20,000 units. When building your landed cost model, use the realistic volume you will actually order – not the volume you hope to reach eventually. Overestimating volume to get a better unit cost is a planning error that compounds through your entire financial model.
What is included in the factory price
Most factory quotes are EXW (Ex Works) or FOB (Free on Board). Make sure you understand exactly what the quote includes:
- EXW: You pay all costs from the factory door. The factory price covers production only – you arrange and pay for all inland transport, export customs, and freight.
- FOB: The factory price includes delivery to the port of origin and export customs clearance. This is the more common starting point for most brands.
- CIF: Cost, Insurance, and Freight included to the destination port. Less common but sometimes offered for large orders.
Always confirm which Incoterm applies to your quote. The difference between EXW and FOB can add $0.50 to $2.00 per unit depending on factory location and inland transport costs.
Component 2: Tooling Amortization
If your product requires injection molds, dies, or other production tooling, you pay for these upfront as a one-time capital expense. But for the purposes of unit economics, it is important to amortize this cost across your production volume.
Example: a set of injection molds costs $15,000. If you produce 5,000 units in your first run, the tooling adds $3.00 per unit to your cost. At 15,000 units cumulative production, it drops to $1.00 per unit. At 50,000 units, it becomes negligible.
This matters for two reasons. First, your unit economics look very different on a first run versus at scale – make sure you understand both. Second, tooling cost is a fixed hurdle that makes very small initial orders expensive on a per-unit basis, which is one reason minimum order quantities exist.
Learn more about tooling costs and what drives them in our guide on injection molding for consumer products.
Component 3: International Freight
Freight is often the component that surprises first-time importers the most – both in cost and in complexity.
Ocean freight
Ocean freight is priced by container (FCL – Full Container Load) or by cubic meter (LCL – Less than Container Load) for smaller shipments. A standard 20-foot container from China to a US port costs roughly $1,500 to $4,000 depending on origin port, destination port, and market conditions. A 40-foot container runs $2,500 to $6,000 under normal conditions.
To calculate ocean freight per unit, divide the total container cost by the number of units that fit in the container. This depends on your product’s dimensions and how efficiently it can be packed. A product that packs densely might see $0.15 to $0.30 per unit in ocean freight. A bulky product might see $1.50 or more.
Transit time from major Chinese ports to US West Coast is typically 14 to 21 days. East Coast adds another 7 to 10 days via all-water routing, or can be done faster via West Coast with inland rail.
Air freight
Air freight costs approximately $4 to $8 per kilogram from Asia to the US, compared to roughly $0.20 to $0.50 per kilogram by ocean. For heavy or bulky products, air freight is almost never viable as a regular shipping method. For lightweight, high-value products where time matters, it can be justified for specific shipments. Use air for launches, urgent restocks, and samples – not for your standard replenishment orders.
Inland freight
Do not forget the cost of moving goods from the US port to your warehouse. Drayage from port to a nearby warehouse or freight station can run $300 to $800. Long-haul trucking from a West Coast port to a Midwest or East Coast warehouse adds $1,500 to $3,500 depending on distance and volume.
Component 4: Import Duties and Tariffs
This is the component that has the biggest range and the most complexity – and the one most founders underestimate.
HTS codes and base duty rates
Every product imported into the US is classified under a Harmonized Tariff Schedule (HTS) code, which determines the base import duty rate. Rates vary widely by product category – from 0% for many industrial goods to 20% or more for certain consumer products. You must identify the correct HTS code for your product before calculating your landed cost.
The US International Trade Commission maintains a searchable HTS database. For products with complex classifications, consulting a licensed customs broker is worth the cost – misclassifying your product can result in underpayment (which creates liability) or overpayment (which damages your margins).
Section 301 tariffs on Chinese goods
Since 2018, most goods imported from China have been subject to additional Section 301 tariffs ranging from 7.5% to 25% on top of standard duty rates. These tariffs apply to the vast majority of consumer product categories. For a product with a $5.00 factory price, a 25% tariff adds $1.25 per unit in import duty alone – before any other costs.
This is one of the primary reasons brands are evaluating manufacturing in Vietnam, which is not subject to these additional tariffs. If China tariffs are materially affecting your landed cost, read our comparison of moving manufacturing from China to Vietnam.
Duty calculation
Import duties are calculated on the customs value of the goods, which is generally the transaction value – the price you paid the factory. Freight and insurance costs are typically not included in the customs value for US imports (unlike EU imports, where CIF value is used). This is an important distinction when calculating your total duty liability.
Component 5: Customs Clearance Fees
Clearing your goods through US Customs requires a licensed customs broker. Brokerage fees for a standard commercial shipment typically run $150 to $400 per entry. Additional fees may include:
- ISF filing (Importer Security Filing): Required 24 hours before cargo is loaded at origin. Typically $25 to $50.
- Customs bond: Required for commercial imports. Annual continuous bonds run $500 to $600 per year for most importers, or single-entry bonds cost roughly 0.5% of the shipment value.
- Harbor maintenance fee (HMF): 0.125% of the cargo value on ocean shipments.
- Merchandise processing fee (MPF): 0.3464% of the cargo value, with a minimum of $31.67 and maximum of $575.35 per entry.
For most shipments, total customs clearance costs run $400 to $800 per entry. On a 1,000-unit order, that is $0.40 to $0.80 per unit. On a 10,000-unit order, it becomes negligible.
Component 6: Insurance
Cargo insurance protects your shipment against loss or damage in transit. Standard marine cargo insurance costs approximately 0.3% to 0.5% of the shipment value. On a $20,000 shipment, that is $60 to $100 – a small cost relative to the risk of losing an entire container.
Do not skip cargo insurance to save money. Ocean shipping, while reliable, does occasionally result in lost containers, damaged goods, or water intrusion. Without insurance, your only recourse against the carrier is typically limited to their published liability limits, which are often far below the actual value of the goods.
Component 7: Warehousing and Fulfillment
Once your goods clear customs, they need to go somewhere – and getting them to your end customers costs money. The specifics depend heavily on your distribution channel.
Direct to warehouse
If you warehouse inventory yourself, factor in the cost per unit for receiving, storage, and outbound shipping. For a product going directly to retail or B2B buyers in large quantities, this cost can be relatively low.
Third-party logistics (3PL)
Most e-commerce and DTC brands use a 3PL to receive, store, and ship orders. 3PL fees typically include a receiving fee per pallet or unit, monthly storage fees per pallet or cubic foot, and a pick-and-pack fee per order. For a small consumer product, total 3PL costs per unit shipped often run $2.00 to $5.00 depending on order size and service level.
Amazon FBA
If you sell on Amazon, FBA fulfillment fees are calculated based on product size and weight. Standard-size products typically incur $3.00 to $7.00 per unit in FBA fees, plus monthly storage fees. See our guide on sourcing products for Amazon FBA for more detail on how fulfillment costs affect your Amazon margin.
Putting It All Together: A Landed Cost Example
Here is how a landed cost calculation looks in practice for a hypothetical consumer product – a plastic household gadget sourced from China:
- Factory unit price (FOB, 2,000 units): $4.50
- Tooling amortization ($12,000 / 10,000 units lifetime): $1.20
- Ocean freight (LCL, 2,000 units): $0.65
- Import duty (standard rate 6.5% + Section 301 tariff 25%): $1.40
- Customs clearance and fees: $0.35
- Cargo insurance: $0.08
- 3PL receiving and storage: $0.40
- Total landed cost per unit: $8.58
The factory price was $4.50. The true landed cost is $8.58 – nearly double. A product priced at $19.99 retail with a 40% wholesale discount to retailers sells to the retailer at $11.99. After landed cost, gross margin per unit is $3.41 – before marketing, overhead, or returns. That is a viable business, but not a comfortable one. If the factory price had been $6.00 instead of $4.50, the whole model might collapse.
This is why landed cost needs to be calculated before product design is finalized – not after. Design decisions affect unit cost, which affects every number downstream.
How to Use Landed Cost to Make Better Decisions
Model multiple scenarios
Build your landed cost model at three volume levels: your realistic first order, your 12-month projection, and your scale target. This shows you how unit economics change as you grow and helps you set pricing that works now and at scale.
Test sourcing region sensitivity
If Section 301 tariffs are a significant cost driver, model what landed cost looks like with production in Vietnam instead of China. In some cases the duty savings more than offset any difference in factory pricing or freight costs. In others, China’s manufacturing ecosystem advantages outweigh the tariff burden. The numbers will tell you which applies to your product.
Design to your cost target
If your landed cost model shows that the product cannot be made profitably at your target retail price, that is a design problem – not just a sourcing problem. Work backwards from your required landed cost to set a factory price target, then work with your designer and engineers to hit it. This is exactly why DFM review is built into our design process – cost optimization starts at the design stage.
