Most importers quote their products based on the supplier's unit price and a rough freight estimate. Then the shipment arrives and the real bill — customs duties, Section 301 tariffs, MPF, HMF, ISF filing, broker fees, and drayage — is 30–50% higher than expected. That gap is why landed cost calculations matter.

This guide walks through every cost component you need to include, the exact Excel formulas to calculate them, and a free template you can download and use today.

What Is Landed Cost?

Landed cost is the total cost to get an imported product to your US warehouse, fully cleared through customs. It includes every cost from the supplier's door to yours — not just the product price and freight.

Cost CategoryWhat It IncludesTypical Range
Supplier CostUnit price × quantityVaries
FreightOcean or air freight charges$500 – $5,000+ per container
Origin ChargesExport trucking, port fees, origin docs$150 – $400
InsuranceCargo insurance (~0.3% of value)$30 – $500
US Customs DutyBased on HTS code duty rate × CIF value0% – 25%+
Section 301 TariffAdditional China tariff (if applicable)0%, 7.5%, 25%
MPFMerchandise Processing Fee (0.3464%)$31.67 – $614.35
HMFHarbor Maintenance Fee (0.125%, ocean only)Varies
ISF FilingImporter Security Filing$35 – $50
Customs BrokerBroker fee for customs clearance$100 – $300
DrayagePort to your warehouse delivery$200 – $800

Step 1 — Find Your HTS Code and Duty Rate

Every product imported into the US has a 10-digit HTS (Harmonized Tariff Schedule) code. The code determines your base customs duty rate. Look yours up at hts.usitc.gov — search by product description.

💡 HTS codes matter more than you think. The difference between two similar HTS codes can mean 0% vs 12% duty. If you are importing frequently, ask your customs broker to confirm the correct classification for your product.

Step 2 — Check Your Section 301 Tariff Rate

If you are importing from China, you may owe an additional Section 301 tariff on top of the base duty. Current rates are 0%, 7.5%, or 25% depending on the product category. Check the current list at ustr.gov — rates and exclusions change, so verify before you quote.

⚠️ Section 301 rates are applied to the CIF value (Cost + Insurance + Freight), same as base customs duty. Not to the FOB price alone. This is a common calculation mistake.

Step 3 — Calculate the CIF Value

CIF (Cost, Insurance, Freight) is the basis US Customs uses to calculate duties. If your incoterm is FOB, you need to add freight and insurance to get CIF.

= (Unit Price × Quantity) + Freight + Insurance Example: Unit Price: $12.50 × 500 units = $6,250 Ocean Freight: $850 Insurance: $45 CIF Value = $6,250 + $850 + $45 = $7,145

Step 4 — Calculate US Customs Duty

Customs Duty = CIF Value × Duty Rate Example: $7,145 × 7.5% = $536

Step 5 — Calculate Section 301 Tariff (China imports)

Section 301 = CIF Value × Section 301 Rate Example: $7,145 × 25% = $1,786

Step 6 — Calculate MPF (Merchandise Processing Fee)

MPF is charged by US Customs on most commercial imports. The rate is 0.3464% of CIF value, with a minimum of $31.67 and a maximum of $614.35 per entry.

Excel formula: =MAX(MIN(CIF_Value * 0.003464, 614.35), 31.67) Example: MAX(MIN($7,145 × 0.3464%, $614.35), $31.67) = MAX(MIN($24.75, $614.35), $31.67) = $31.67 ← minimum applies here
💡 MPF hits the minimum on small shipments. If your CIF value is under ~$9,145, you will pay the minimum $31.67 regardless. This matters when comparing air vs ocean for small orders.

Step 7 — Calculate HMF (Harbor Maintenance Fee)

HMF applies to ocean freight shipments only. The rate is 0.125% of CIF value — no minimum or maximum.

HMF = CIF Value × 0.00125 Example: $7,145 × 0.125% = $8.93

Step 8 — Add Fixed Fees

These are negotiated or fixed costs you collect from your broker and freight forwarder:

Step 9 — Build the Summary in Excel

Once you have all the components, sum them for total landed cost and divide by quantity for per-unit cost:

Total Landed Cost = Supplier Cost + Freight + Origin Charges + Insurance + Customs Duty + Section 301 Tariff + MPF + HMF + ISF + Broker Fee + Drayage Landed Cost Per Unit = Total Landed Cost / Order Quantity Suggested Selling Price = Landed Cost Per Unit / (1 - Target Margin %)

Full Example — 500 units imported from China

Unit price $12.50 · HTS duty 7.5% · Section 301 25% · Ocean freight $850 · Fixed fees $530

Cost ItemAmount
Supplier Cost (500 × $12.50)$6,250.00
Ocean Freight$850.00
Origin Charges$220.00
Insurance$45.00
CIF Value$7,145.00
Customs Duty (7.5%)$535.88
Section 301 Tariff (25%)$1,786.25
MPF (min $31.67)$31.67
HMF (0.125%)$8.93
ISF + Broker + Drayage$530.00
Total Landed Cost$10,257.73
Landed Cost Per Unit$20.52
Suggested Price (40% margin)$34.19

The supplier quoted $12.50 per unit. The actual landed cost is $20.52 — 64% higher. Without this calculation, any price below ~$21 would lose money.

How to Build This in Excel

1

Set up an inputs section

List every input in its own cell — unit price, quantity, freight, duty rate, etc. Color these blue so anyone using the file knows which cells to edit.

2

Calculate CIF value

Reference your input cells: =(UnitPrice*Qty)+Freight+Insurance. All subsequent duty calculations reference this cell.

3

Use MAX/MIN for MPF

MPF has a floor and ceiling: =MAX(MIN(CIF*0.003464, 614.35), 31.67). Hardcoding the rate and bounds prevents errors when values change.

4

Add a comparison sheet

Duplicate your formula structure across 3 columns — one per supplier. Use conditional formatting to highlight the lowest per-unit landed cost automatically.

💡 Build your template once, use it forever. Once your landed cost model is set up correctly in Excel, updating it for a new shipment takes 2 minutes — just change the blue input cells.

FAQ

What is the difference between FOB and CIF for duty calculation?
FOB (Free On Board) is the price of goods at the port of export — it does not include freight or insurance. CIF (Cost, Insurance, Freight) adds those to get the value at the US port of entry. US Customs calculates duties on the CIF value. If your supplier quotes FOB, you must add freight and insurance before applying the duty rate. Using FOB as the duty base underestimates your duty bill.
Do I pay Section 301 tariffs on every shipment from China?
Not necessarily. Section 301 tariffs apply to specific product categories (Lists 1–4B), and many products have received exclusions. Check the USTR exclusion list at ustr.gov before assuming you owe 25%. Some categories are 7.5% rather than 25%. Your customs broker can confirm the correct rate for your HTS code.
Does MPF apply to every shipment?
MPF applies to most commercial imports, but there are exceptions. Goods qualifying under USMCA (from Canada or Mexico) are generally MPF-exempt. Some other free trade agreement goods are also exempt. Check with your broker if you think your goods might qualify for an exemption.
How do I find the right HTS code for my product?
Go to hts.usitc.gov and search by product description. Start broad (e.g., "cotton shirt") and narrow down using the chapter notes. If you are unsure, ask your customs broker — misclassification can result in penalties or unexpected duty bills. For high-volume imports, consider requesting a Binding Ruling from US Customs (CBP) to get official confirmation of your HTS code.
