How the calculation works
- Classify the product into a 10-digit HTS code using an AI classifier trained on CROSS rulings plus the product description.
- Identify country of origin and select the applicable tariff column (Column 1 General for WTO members, Column 2 for non-NTR, free-trade preferences for FTA eligibles).
- Layer on active surcharges: Section 301 (China Lists 1–4A), Section 232 (steel/aluminum), Section 122 (reciprocal), and IEEPA actions (Russia/Belarus/Iran/Cuba/Venezuela) where they apply.
- Check trade-agreement preferences — USMCA, KORUS, CAFTA-DR, Israel FTA, etc. — and apply the preferential rate only when rules of origin are satisfied.
- Sum the final rate, apply it to the declared customs value, and output the estimated duty + total landed cost.

What Makes TariffCheck Different
Unlike the official USITC HTS search that requires you to already know your classification code, TariffCheck uses AI to identify the right HTS code from a plain English product description and calculates all applicable tariffs automatically.

| Customs Broker Consultation | Brokers charge $150-300/hr; TariffCheck provides instant free estimates |
| Manual HTS Lookup | Manual lookup takes 30-60 minutes; TariffCheck takes under 10 seconds |

Frequently Asked Questions
How does TariffCheck work?
TariffCheck uses AI to analyze your product description and identify the most likely HTS (Harmonized Tariff Schedule) code. It then calculates the base duty rate, adds any Section 301 tariffs (for Chinese goods) and Section 122 surcharges, estimates shipping costs, and produces a total landed cost breakdown in seconds.
Is it free to try?
You get 3 free tariff calculations on signup with no credit card required. After that, purchase 50 credits for $5 (one-time). Each credit generates one full tariff breakdown.
How accurate is the tariff estimate?
TariffCheck provides AI-based estimates using 2026 tariff data. For informal entries under $2,500, accuracy is typically within 1-3% of actual duty. For formal entries or complex products, always confirm with a licensed customs broker before importing.
What countries are supported?
TariffCheck supports imports from any country into the United States. Section 301 tariffs are automatically applied for products from China. Most Favored Nation (MFN) rates are used for other countries unless a free trade agreement applies.
What are Section 301 tariffs?
Section 301 tariffs are additional duties imposed on Chinese goods as part of the US-China trade dispute. In 2026, these range from 7.5% to 100% depending on the product category, on top of the regular duty rate.
What are Section 122 surcharges?
Section 122 surcharges are tariff surcharges applied to imports from specific countries. In 2026, these affect imports from several countries and are calculated on top of regular duties.
How long do credits last?
Credits never expire. Once purchased, your 50 credits are available until used. No monthly fees or subscriptions.
Is my data safe?
We do not store your product descriptions or calculation results after your session ends. See our Privacy Policy for details.
What makes TariffCheck different from hiring a customs broker?
Customs brokers charge $150-300 per consultation and take days to respond. TariffCheck provides instant AI-powered estimates for free. Use TariffCheck for quick feasibility checks, then hire a broker when you are ready to import.
