Landed Cost Calculation for Amazon Sellers: دليل شامل

Your supplier in Yiwu quotes you $3.50 per unit. You build your profitability model around $3.50. Then reality arrives: freight costs $0.80 per unit. Customs duty adds $0.42. The customs broker charges $150 flat (divide by 2,000 units = $0.08). Inspection costs $0.12. Insurance runs $0.04. Inland trucking from port to Amazon FBA warehouse adds $0.35. Prep and labeling costs $0.25. Inbound placement service fee adds another $0.27.

Your $3.50 product actually costs $5.83 by the time it reaches an Amazon FBA shelf. That $2.33 gap -- a 67% markup over factory price -- is the difference between the product analysis that works on paper and the one that works in practice.

This guide walks through every component of landed cost, with real numbers, so you can model your true per-unit economics before you commit capital.

The Landed Cost Formula

Landed cost is the total cost to get one unit from the factory floor to the Amazon FBA warehouse, ready for sale. The formula:

Landed Cost = Factory Price + International Freight + Customs Duty + Import Fees + Insurance + Inland Transport + Prep/Labeling + Inbound Placement

Let us break down each component.

Component 1: Factory Price (FOB or EXW)

The factory price is your starting point, but the quoted price depends on the trade term (Incoterm):

• EXW (Ex Works): Price covers the product only. You pay for everything from the factory door onward, including local trucking to the port. Lowest quoted price, highest total responsibility.
• FOB (Free on Board): Price covers the product plus all costs to load it onto the shipping vessel. The most common term for Amazon البائعون sourcing from China. Your costs begin once goods are on the ship.
• CIF (Cost, Insurance, Freight): Price covers product + insurance + freight to the destination port. Less common because البائعون lose control over freight negotiation.

Most Amazon FBA suppliers quote FOB. If they quote EXW, add $0.10-$0.30 per unit for local trucking to port, depending on factory location relative to the shipping port.

Component 2: International Freight

This is usually the largest single cost component after factory price. The mode of transport drastically changes the math:

Sea Freight (Ocean)

To calculate per-unit sea freight, you need the total CBM (cubic meters) of your shipment. Example: 2,000 units of a product packed 50 per carton, each carton measuring 0.04 CBM = 40 cartons x 0.04 = 1.6 CBM. At $65/CBM for LCL: 1.6 x $65 = $104 total, or $0.05 per unit.

ومع ذلك, minimum charges apply. Most LCL shipments have a minimum of 1 CBM ($50-$80 even if your shipment is 0.5 CBM). And additional surcharges (BAF, CAF, port congestion, peak season) can add 20-40% on top of base rates.

Air Freight

Air freight is charged by whichever is greater: actual weight or volumetric weight. Volumetric weight = (L x W x H in cm) / 5000 per package. Light, bulky items are particularly expensive to ship by air.

Sea vs. Air: Worked Comparison

For our $3.50 product (weight: 0.3 kg, dimensions: 20x15x10 cm, order: 2,000 units):

Sea freight is 11x cheaper than air for this product. The tradeoff is 27 additional days of transit time -- which means 27 more days of carrying cost on your capital and 27 more days of stockout risk if you are reordering.

Component 3: Customs Duty

U.S. Customs duty is calculated as a percentage of the "customs value" (typically the FOB price plus freight). The duty rate depends on the product's HS (Harmonized System) code.

Finding Your HS Code

The HS code is a 6-10 digit classification number that determines your duty rate. To find it:

1. Search the USITC Harmonized Tariff Schedule at hts.usitc.gov
2. Use the product description to narrow down the chapter (e.g., Chapter 39 for plastics, Chapter 73 for steel articles)
3. Drill down to the 8 or 10-digit code that matches your specific product

Common HS codes and duty rates for Amazon FBA products:

Important: Products from China may be subject to additional Section 301 tariffs of 7.5% to 25% on top of the base duty rate. Check the USTR exclusion lists, as these tariffs change periodically. As of early 2026, many consumer goods from China carry an additional 7.5-25% tariff depending on the category.

For our $3.50 silicone product with 3.4% base duty + 7.5% Section 301:

Duty = ($3.50 + $0.14 freight) x (3.4% + 7.5%) = $3.64 x 10.9% = $0.40 per unit

Component 4: Customs Brokerage and Import Fees

A customs broker handles your import paperwork and clearance. Typical fees:

• Customs broker fee: $125-$250 per entry (flat fee per shipment)
• Merchandise Processing Fee (MPF): 0.3464% of goods value, minimum $31.67, maximum $614.35
• Harbor Maintenance Fee (HMF): 0.125% of goods value (sea shipments only)
• ISF filing fee: $25-$50 per shipment (sea only; Importer Security Filing required 24 hours before vessel departure)

For a 2,000-unit shipment valued at $7,000 FOB:

• Broker fee: $150 / 2,000 = $0.08/unit
• MPF: $7,000 x 0.3464% = $24.25, minimum applies = $31.67 / 2,000 = $0.02/unit
• HMF: $7,000 x 0.125% = $8.75 / 2,000 = less than $0.01/unit
• ISF: $35 / 2,000 = $0.02/unit

Component 5: Insurance

Cargo insurance typically costs 0.5-1.5% of the shipment value (goods + freight). For a $7,280 shipment (goods + freight):

Insurance = $7,280 x 1.0% = $72.80 / 2,000 units = $0.04 per unit

Some البائعون skip insurance to save costs. This is a bad decision for shipments over $5,000. A single lost or damaged container can wipe out a year of profits. The $0.04 per unit is a rounding error in your landed cost.

Component 6: Inland Transport (Port to FBA)

Once goods clear customs at the U.S. port, they need to reach an Amazon FBA warehouse. Options:

• LTL (Less Than Truckload): $200-$600 for palletized shipments from West Coast ports to FBA warehouses. Per-unit cost depends on shipment size.
• Drayage + LTL: Container drayage from port to a local warehouse ($300-$600), then LTL to FBA ($200-$500).
• Direct-to-FBA from port: Some freight forwarders offer this as a bundled service, typically $0.20-$0.50 per unit depending on location and volume.

For our example: LTL from LA port to FBA warehouse in California = approximately $350 / 2,000 units = $0.18 per unit. If the FBA warehouse is in the Midwest or East Coast, add another $0.15-$0.25 per unit.

Component 7: Prep, Labeling, and Inspection

• Pre-shipment inspection (China): $250-$350 per inspection / 2,000 units = $0.13-$0.18 per unit
• FNSKU labeling: $0.15-$0.30 per unit (if not done at factory)
• Poly bagging: $0.10-$0.20 per unit (if required by Amazon)
• Bundling/kitting: $0.25-$0.50 per unit (if selling multi-packs)

Many البائعون have the factory handle labeling and poly bagging for $0.05-$0.10 per unit, which is significantly cheaper than doing it in the U.S.

Component 8: Amazon Inbound Placement Fee

Since 2025, Amazon charges an inbound placement service fee for shipments sent to a single fulfillment center (rather than splitting inventory across multiple locations). The fee varies by product size and ranges from $0.21 to $0.68 per unit for standard-size items. Sending to multiple destinations can reduce or eliminate this fee but increases your inland shipping complexity.

The Complete Worked Example

Let us assemble all costs for our silicone kitchen product:

The factory price of $3.50 becomes a landed cost of $4.88 -- a 39% increase. For products with higher duty rates or heavier weight (more expensive freight), the markup can reach 60-100%. A $3.50 cotton product with a 17.6% duty rate and heavier weight might land at $6.80 or more.

Common Landed Cost Mistakes

Using factory price as COGS. The most damaging mistake. If your FBA fee analysis uses $3.50 instead of $4.88, your margin calculation is wrong by $1.38 per unit. At 400 units/month, that is a $6,624 annual error.

Forgetting Section 301 tariffs. The base duty rate from the HTS schedule is only part of the picture. Additional tariffs on Chinese goods can double or triple the effective duty rate for some product categories.

Ignoring dimensional weight for air freight. A product that weighs 200g but occupies significant volume may cost 3x more to air ship than the actual weight suggests. Always calculate volumetric weight before quoting air freight.

Not factoring in reorder shipping costs. Your first order might be 2,000 units where per-unit shipping costs are spread efficiently. But if you need to restock with a 500-unit emergency air shipment, the per-unit freight could be $2-4 instead of $0.14. Build reorder scenarios into your cashflow forecast.

Reducing Your Landed Cost

Based on sensitivity analysis, COGS (including landed cost) is typically the 3rd or 4th most impactful variable on profitability. Here are practical ways to reduce it:

1. Increase order quantities. Factory prices typically drop 5-15% when you double your MOQ. Freight per unit also decreases with larger shipments.
2. Negotiate FOB vs. EXW. Ask for FOB pricing where the supplier handles local logistics. The difference is usually small for the supplier but saves you coordination overhead.
3. Consolidate shipments. If you sell multiple products from the same region, consolidating into one container reduces per-unit freight dramatically.
4. Optimize packaging dimensions. Reducing your carton size by even 10% can meaningfully reduce freight costs for LCL and air shipments. Work with your supplier to minimize packaging volume without compromising product protection.
5. Check for duty exemptions. Some products qualify for duty-free entry under GSP (Generalized System of Preferences) or specific trade agreements. If you source from Vietnam, India, or other GSP-eligible countries, duty rates may be significantly lower than from China.

Landed Cost as a Distribution, Not a Point

Your landed cost is not a fixed number. Freight rates fluctuate seasonally (peak season surcharges in Aug-Oct), duty rates change with trade policy, and exchange rates affect factory pricing. When building your Monte Carlo simulation, assign a distribution to your landed cost -- typically a triangular distribution with a minimum (best-case freight + current duties), mode (expected landed cost), and maximum (peak-season freight + potential tariff increase).

The difference between a $4.88 and $5.80 landed cost is $0.92 per unit. At 5,000 annual units, that is $4,600 in profit variance from a single cost component that most البائعون treat as fixed.
