How to Calculate Landed Cost (Complete Formula)

Landed cost is the total cost of bringing a product from a foreign supplier to your US warehouse or fulfillment center. It includes the supplier's price plus every cost incurred to clear US customs and complete delivery: ocean or air freight, customs duties, merchandise processing fee (MPF), harbor maintenance fee (HMF), customs broker fees, port handling, drayage, and final-mile delivery. The term "landed" refers to the cost once the goods have "landed" on US soil — after customs clearance. Landed cost is the number that should inform your pricing, margin analysis, and sourcing decisions. A supplier quote of "$10/unit FOB Shanghai" is not your landed cost. After freight, duties, and fees, that $10 unit may actually cost $15–18 to land in a US warehouse. In 2026, with stacked tariff rates in the 20–50% range for most imports, the gap between FOB price and landed cost is larger than at any point since the 1940s. Businesses that do not accurately calculate landed cost are systematically underpricing their products, overstating margins, and making incorrect sourcing decisions. This guide provides the complete landed cost formula, a step-by-step calculation process, and worked examples for two common scenarios.

Landed Cost = Customs Value × (1 + Total Tariff Rate%) + MPF + HMF + Freight + Insurance + Broker Fees + Port/Handling Fees Breaking down each component: Customs Value: Generally the transaction value — what you paid your supplier, including commissions and certain assists. If you paid $15,000 FOB for a shipment, customs value is $15,000. For CIF (cost, insurance, freight) terms, customs value excludes US inland freight but may include international freight and insurance, depending on terms. Total Tariff Rate: MFN rate + max(Section 122, Section 232, Bilateral Deal) + Section 301 (China only). This is the stacked rate that applies to your specific product (HTS code) from your specific country. MPF: Merchandise Processing Fee = 0.3464% of customs value, minimum $33.58, maximum $651.50 per entry. Almost every commercial import pays MPF. HMF: Harbor Maintenance Fee = 0.125% of customs value. Applies only to ocean shipments arriving at maintained ports. Does not apply to air freight or overland (Canada, Mexico) entries. Other fees: customs broker fees typically $75–250 per entry; ISF (Importer Security Filing) $25–75; port handling/drayage $150–400 depending on port and container size.

Incoterms define who pays for freight and insurance and where risk transfers. They also affect how customs value is calculated. FOB (Free on Board): Seller delivers goods to the named port. Buyer pays ocean freight and insurance. Customs value = the transaction value = what you paid the seller. If you paid $15,000 FOB and freight cost $1,500 and insurance $150, customs value is $15,000 (freight and insurance excluded). CIF (Cost, Insurance, Freight): Seller pays ocean freight and insurance to named port. Customs value under CBP rules = transaction value including freight and insurance to the point of importation. A $15,000 CIF order where freight is embedded in the price has a higher customs value than FOB — the full $15,000 (or more, if the invoice separately states freight). DAP/DDP (Delivered At Place/Delivered Duty Paid): The seller handles freight, insurance, and sometimes duties. Under DDP, customs value is typically the transaction value minus US customs duties (since the seller is paying them, they are not part of the "value" for which the buyer paid). DDP is complex for customs valuation and requires careful calculation. Practical implication: if you have a choice between FOB and CIF from the same supplier at the same total cost to you, FOB typically results in a slightly lower customs value (because you arrange and pay freight separately, not through the customs value), which slightly reduces duty amounts.

Step 1: Identify your HTS code. Every import is classified under the Harmonized Tariff Schedule (HTS). The HTS code determines your MFN duty rate. Use the USITC tariff schedule (hts.usitc.gov) or the CalcMyTariff.com HTS Lookup tool. Example: consumer electronics — HTS 8517.62.00 has MFN rate of 0% (some electronics are duty-free at MFN; always verify your specific HTS). Step 2: Determine country of origin. Not where the goods ship from, but where they were manufactured. Origin determines which tariff authorities apply (Section 301 only applies to Chinese-origin goods, USMCA only for Canadian/Mexican-origin). Step 3: Apply the stacking formula: Total Rate = MFN + max(S122, S232, Bilateral) + S301. For electronics from Vietnam: MFN 0% (HTS 8517.62.00) + bilateral 18% + S301 0% = 18%. Step 4: Calculate duty amount: Customs Value × Total Rate. $15,000 × 18% = $2,700. Step 5: Calculate MPF: $15,000 × 0.003464 = $51.96 (minimum $33.58, maximum $651.50). Use $51.96. Step 6: Calculate HMF (ocean only): $15,000 × 0.00125 = $18.75. Step 7: Sum total import fees: $2,700 (duty) + $51.96 (MPF) + $18.75 (HMF) + $150 (broker) = $2,920.71. Step 8: Calculate landed cost: $15,000 (FOB) + $1,500 (freight) + $150 (insurance) + $2,920.71 (import fees) = $19,570.71.

Product: Consumer electronics (smartphones), HTS 8517.62.0090. Country: Vietnam (bilateral deal 18%). Incoterms: FOB Ho Chi Minh City. Customs value (FOB price): $15,000. Tariff calculation: MFN rate for HTS 8517.62: 0%. Bilateral deal rate (Vietnam): 18%. Section 301: not applicable (Vietnam). Total tariff rate: 0% + 18% = 18%. Duty: $15,000 × 18% = $2,700. MPF: $15,000 × 0.003464 = $51.96. HMF (ocean shipment): $15,000 × 0.00125 = $18.75. Freight (ocean, HCMC to Los Angeles): estimated $1,200 for LCL (less-than-container load). Insurance: $15,000 × 0.01 = $150 (1% of value, standard marine cargo rate). Customs broker fee: $175. ISF filing: $50. Port handling / drayage: $200. Total landed cost: $15,000 + $2,700 + $51.96 + $18.75 + $1,200 + $150 + $175 + $50 + $200 = $19,545.71. Effective all-in rate above FOB: 30.3% ($4,545.71 / $15,000). This is meaningfully higher than the headline 18% tariff rate — logistics and fees add approximately 12 percentage points to the FOB-to-landed cost gap.

Product: Hot-rolled steel coil, HTS 7208.51.00. Country: Germany (no bilateral deal, standard S232). Incoterms: CIF Hamburg. Customs value: $8,000 (CIF price, includes freight and insurance paid by seller). Tariff calculation: MFN rate for HTS 7208.51: approximately 1.1%. Section 232 (steel): 50%. Note: S232 products are excluded from Section 122. Germany has no bilateral deal. Total tariff rate: MFN 1.1% + S232 50% = 51.1%. Section 301: not applicable (Germany). Duty: $8,000 × 51.1% = $4,088. MPF: $8,000 × 0.003464 = $27.71. But minimum is $33.58, so MPF = $33.58. HMF: $8,000 × 0.00125 = $10. (CIF includes freight to US port, so HMF applies.) Freight: $0 (included in CIF price). Insurance: $0 (included in CIF price). Customs broker: $175. Drayage: $250. Total landed cost: $8,000 + $4,088 + $33.58 + $10 + $175 + $250 = $12,556.58. Effective all-in rate above CIF: 57% ($4,556.58 / $8,000). Steel's S232 rate makes it among the most expensive product categories to import in 2026.

Mistake 1: Using only the MFN tariff rate. The MFN rate alone does not include Section 122, Section 232, or Section 301. A 5% MFN rate becomes 20% after adding S122, or 30% for Chinese goods. Mistake 2: Forgetting MPF minimum. For low-value shipments, MPF minimum ($33.58) may exceed the ad valorem MPF. A $200 shipment has $0.69 in ad valorem MPF — but pays $33.58 minimum. The minimum transforms the economics of small-value imports. Mistake 3: Applying S301 to non-China goods. Section 301 applies only to Chinese-origin goods. A product manufactured in Vietnam — even by a Chinese-owned company using Chinese components — is Vietnamese origin if it meets origin rules. Mistake 4: Applying S122 to S232 products. Steel, aluminum, copper, lumber, autos, auto parts, and semiconductors are excluded from Section 122. Adding S122 to S232 overstates the tariff burden for these categories. Mistake 5: Using FOB value when goods are shipped CIF. Customs value differs between FOB and CIF terms. Always determine customs value correctly before applying tariff rates. Mistake 6: Not accounting for HMF on ocean shipments. HMF (0.125%) is often forgotten and adds $125 per $100,000 in goods — small but not zero.
