What is the US tariff calculator and how does it work?

The US Tariff Calculator is a free tool that estimates the total cost of importing goods into the United States. It calculates customs duties based on the country of origin, adds required fees (MPF and HMF), and provides a complete breakdown of your landed costs. Simply enter your product cost, shipping cost, quantity, and select the country of origin to get instant calculations.

How are US import duties calculated?

Import duties are calculated by multiplying the customs value (product cost + shipping cost) by the tariff rate for your product's country of origin. Tariff rates vary by country, ranging from 10% for some nations to 50% for others like India and Brazil. The actual rate also depends on the specific product classification (HTS code).

What is the Merchandise Processing Fee (MPF)?

The Merchandise Processing Fee (MPF) is a fee charged by U.S. Customs and Border Protection for processing imported goods. It's calculated as 0.3464% of the customs value, with a minimum of $27.98 and a maximum of $538.40 per shipment. This fee applies to most commercial imports and is separate from duty charges.

What is the Harbor Maintenance Fee (HMF)?

The Harbor Maintenance Fee (HMF) is a 0.125% fee on the customs value of goods shipped by sea. It funds the maintenance and improvement of U.S. ports and harbors. This fee only applies to shipments arriving by vessel, not air cargo. In our calculator, you can toggle HMF on or off depending on your shipping method.

What are the current US tariff rates for major countries?

As of August 2025, major tariff rates include: China (30%), Canada (35%), Mexico (25%), India (50%), Brazil (50%), EU countries (15%), Japan (15%), South Korea (15%), Vietnam (20%), and a global base rate of 10% for most other countries. These rates can vary by product type and are subject to change based on trade policies.

How do I find the correct tariff rate for my product?

The exact tariff rate depends on your product's Harmonized Tariff Schedule (HTS) code, which is a 10-digit classification number. Our calculator uses general country-level rates for estimation. For precise rates, consult the official HTSUS (Harmonized Tariff Schedule of the United States) or work with a licensed customs broker who can identify the exact HTS code for your product.

What is customs value and how is it calculated?

Customs value (also called transaction value) is the basis for calculating duties and fees. It's calculated as the product cost (price paid to the supplier) plus international shipping costs. This value does not typically include domestic shipping, insurance (unless included in the shipping cost), or the duty itself. Accurate customs value declaration is required by law.

How can I reduce import duties and tariffs?

Several strategies can help reduce tariff costs: (1) Source from countries with lower tariff rates or free trade agreements, (2) Ensure proper HTS classification (some codes have lower rates), (3) Consider duty drawback programs if you re-export goods, (4) Look into Foreign Trade Zones (FTZ) for deferred duties, (5) Review if your product qualifies for any preferential programs like GSP (Generalized System of Preferences). Always consult with a customs professional for specific advice.

Do all products from the same country have the same tariff rate?

No. While our calculator shows general country-level rates, actual tariff rates vary significantly by product type. Two different products from China might have completely different duty rates - one might be 5% while another is 40%. The specific rate is determined by the product's HTS code classification. Our calculator provides estimates based on average rates for each country.

What additional costs should I expect when importing goods?

Beyond tariffs, MPF, and HMF, you should budget for: customs broker fees ($50-$200+ per shipment), ISF filing fees ($25-$75), domestic transportation from port to destination, storage or demurrage fees if shipment isn't picked up promptly, and potentially exam fees if CBP inspects your goods. Some products may also require special certifications, permits, or compliance testing which add to the total cost.
