US Tariff & Import Duty Calculator

Using this tariff calculator takes less than a minute:

1. Enter your product value (FOB): This is the declared value of your goods at the point of origin, not including shipping. FOB (Free on Board) is the standard valuation method used by US Customs for assessing most tariff duties.
2. Enter shipping and insurance costs: Include all freight, insurance, and transportation costs to get the goods to a US port. This is used to calculate the Merchandise Processing Fee and your total landed cost.
3. Select the country of origin: Choose where your goods were manufactured or substantially transformed. Different countries face different tariff rates based on trade agreements and reciprocal tariff policies. China faces the highest additional tariffs (25% under Section 301), while USMCA partners Canada and Mexico have the lowest.
4. Select the product type: General goods face standard tariff rates, but steel and aluminum products face an additional 50% tariff under Section 232. Select the product type that best matches your import.
5. Enter shipments per year: If you import regularly, enter how many times per year you make this shipment to see your estimated annual tariff cost.

Results update instantly as you change any input. The calculator shows a detailed breakdown of each tariff component, your effective tariff rate, and the total landed cost of your goods.

The US Tariff Calculator is a free tool that estimates the total import duties, tariffs, and fees you will owe when bringing goods into the United States. It factors in the current 2026 tariff rates, including the Section 122 global import surcharge, country-specific reciprocal tariffs, Section 232 tariffs on steel and aluminum, and the Merchandise Processing Fee (MPF) charged by US Customs and Border Protection.

Understanding your true import costs is critical for businesses, e-commerce sellers, and individuals who purchase goods from overseas. Tariffs have increased significantly since 2025, with the average effective US tariff rate rising from approximately 2.5% to 13.7%. This calculator helps you estimate the total landed cost of your goods — the true price including product value, shipping, and all government-imposed duties — so you can make informed purchasing and sourcing decisions.

Whether you are an Amazon FBA seller sourcing products from China, a manufacturer importing raw materials, or a small business owner evaluating supplier options across different countries, this calculator provides a quick estimate of what you will owe at the border. For binding tariff classifications and precise duty rates, always consult a licensed customs broker or use the official US International Trade Commission Harmonized Tariff Schedule.

The total import duty is calculated by stacking multiple tariff layers:

• Total Duty = Section 122 Duty + Country-Specific Duty + Section 232 Duty + MPF
• Effective Tariff Rate = (Total Duty ÷ Product Value) × 100
• Landed Cost = Product Value + Shipping & Insurance + Total Duty
• Annual Duty Cost = Total Duty × Number of Shipments per Year

Important: Tariffs stack — they are additive, not applied sequentially. A $10,000 steel product from China faces 10% + 25% + 50% = 85% in tariffs, resulting in $8,500 in duties (plus MPF), not $10,000 × 1.10 × 1.25 × 1.50.

Example 1 — Electronics from China: You import $10,000 worth of consumer electronics from China with $500 in shipping costs. The Section 122 tariff is $10,000 × 10% = $1,000. The Section 301 tariff on Chinese goods is $10,000 × 25% = $2,500. No Section 232 applies to electronics. The MPF is $10,500 × 0.3464% = $36.37. Total duty: $1,000 + $2,500 + $36.37 = $3,536.37. Your effective tariff rate is 35.4%, and your total landed cost is $10,000 + $500 + $3,536.37 = $14,036.37.

Example 2 — Steel from South Korea: You import $25,000 worth of steel from South Korea with $2,000 in shipping. Section 122: $25,000 × 10% = $2,500. Reciprocal tariff: $25,000 × 5% = $1,250. Section 232 on steel: $25,000 × 50% = $12,500. MPF: $27,000 × 0.3464% = $93.53, but capped at $614.35. Total duty: $2,500 + $1,250 + $12,500 + $93.53 = $16,343.53. Effective rate: 65.4%. Landed cost: $43,343.53.

Example 3 — Textiles from Vietnam: A clothing brand imports $50,000 in textiles from Vietnam with $3,000 in shipping. Section 122: $50,000 × 10% = $5,000. Vietnam reciprocal tariff: $50,000 × 10% = $5,000. No Section 232. MPF: $53,000 × 0.3464% = $183.59. Total duty: $5,000 + $5,000 + $183.59 = $10,183.59. Effective rate: 20.4%. Landed cost: $63,183.59.

Example 4 — Auto parts from Mexico (USMCA): You import $15,000 in qualifying auto parts from Mexico with $1,000 in shipping. Under USMCA, the country-specific tariff is 0%. Section 122: $15,000 × 10% = $1,500. MPF: $16,000 × 0.3464% = $55.42. Total duty: $1,555.42. Effective rate: 10.4%. Landed cost: $17,555.42. This demonstrates the advantage of USMCA sourcing for qualifying goods.
