How do I calculate US import duties?

Import duties are a percentage of your product's customs value, determined by its HTS (Harmonized Tariff Schedule) code. For most consumer goods imported from China, duty rates range from 0–20%, plus potential Section 301 tariffs of 7.5–25% on top. Look up your HTS code at hts.usitc.gov or ask your customs broker to verify the applicable rate.

What is the difference between FOB, EXW, and CIF pricing?

EXW (Ex Works): you pay all freight from the factory gate. FOB (Free on Board): supplier pays to load onto the ship at origin port — you pay ocean freight. CIF (Cost, Insurance, Freight): supplier pays ocean freight to destination port — you pay import duties and domestic costs. For Amazon sellers, request FOB pricing to compare suppliers on equal terms.

Landed Cost Calculator

Add every cost from factory to your warehouse door — know your true cost per unit before you place the order

The Landed Cost Calculator adds every cost between your supplier and your Amazon FBA warehouse to give you a true cost per unit. Most sellers only track their FOB product cost and miss freight forwarder fees, customs clearance, import duties, domestic trucking, and Amazon inbound shipping — which can add 30–60% to the product cost alone. Knowing your accurate landed cost is the foundation of every other margin calculation.

Accurate landed cost calculation requires capturing every dollar between the factory and your first sellable unit in FBA. Here's a complete breakdown.

Step 1 — Enter FOB product cost and quantity

Use your per-unit cost at the factory quoted price (FOB China port is standard for Chinese suppliers). Enter your order quantity — both fields are needed to calculate per-unit freight costs.

Step 2 — Enter total freight cost

Get a quote from your freight forwarder for door-to-port or door-to-door shipping. For sea LCL (Less than Container Load): typically $0.50–1.50 per kg. For air freight: $5–10 per kg. This is the total for the shipment — the calculator divides by quantity.

Step 3 — Add customs clearance and duty

Customs clearance fee: typically $150–300 charged by your broker. Duty rate: look up your product's HTS code at hts.usitc.gov to verify the applicable rate (typically 0–25% of customs value). For Chinese-manufactured goods, add Section 301 tariffs if applicable.

Step 4 — Add domestic and inbound costs

Domestic trucking from the port to your warehouse or Amazon inbound: $100–300 for small LCL shipments. Amazon inbound shipping per unit: typically $0.30–1.50 depending on your method (partnered carrier vs. self-ship).

💡 Pro tips

•Always get freight quotes BEFORE placing a large order — rates fluctuate significantly
•Section 301 tariffs on Chinese goods can be 7.5–25% — check your HTS code carefully
•Add 10% buffer to your landed cost estimate for unexpected fees (port congestion, re-inspection, etc.)
•Compare air vs. sea freight: air costs 5–8× more but saves 3–4 weeks of capital tied up in transit
