US Tariff Calculator

Not exactly. Tariffs and import duties are often used interchangeably, but tariffs technically refer to the government-set rate (percentage), while import duties are the actual dollar amount you pay based on that rate applied to the customs value of your goods. In practice, both terms describe the tax charged on imported products.

Multiply your declared customs value (FOB price) by the applicable MFN duty rate, then add China's Section 301 list rate if the goods are Chinese (0% to 100% by HTS code) and the forced-labor Section 301 tariff for the origin (10% or 12.5% for 60 economies; Section 232 goods pay the 232 rate instead). Also add the Merchandise Processing Fee (0.3464%, min $34.58 / max $670.86) and Harbor Maintenance Fee (0.125% for ocean freight). Use the calculator above to get the full landed cost automatically.

Most Chinese goods pay normal (MFN) duty, plus Section 301 by product list, plus the 12.5% forced-labor tariff that has applied since 24 July 2026. A cotton T-shirt (HTS 6109.10.00) pays 36.5% in total: 16.5% + 7.5% + 12.5% (Zentria Flow engine, 9 Nov 2026). Use the calculator above for your product.

Yes. Zentria Flow's tariff calculator covers import duty, VAT/GST, excise duties, and port handling fees for 70+ countries. For example, UK imports include 20% VAT on top of customs duty; EU imports include the applicable VAT rate per member state.

The Harmonized Tariff Schedule (HTS) code is the US version of the international HS code system. It determines the exact tariff rate applied to your product. A 10-digit HTS code maps to a specific duty rate, Section 301 list, anti-dumping orders, and quota status. Every result shows the HS code it used, so you can check it. To find your code, use the HS code lookup.
