3Discover savingsComing Oct 2026

Pay less duty on the same products.

Most savings hide in the products you already import: an exemption nobody claimed, or a trade program left off the entry. HTS Hero checks every product for both, then prices every other country of origin.

  • Exemptions you may qualify for but aren't claiming
  • Trade programs like USMCA, checked on every product
  • Your duty from every other country of origin

This is a complete vacuum-insulated vessel, not a steel kitchen article or residual container. Chapter 96 Note 1(d) and Section XV Note 3 keep vacuum flasks out of the base-metal headings. NY N353266 supports 9617, so that’s the heading I’m taking.

Questions

HTS Hero, answered

What is HTS Hero?

HTS Hero is US tariff software for importers, customs brokers and freight forwarders: it calculates the full duty on any HTS code and country of origin, alerts you when a tariff change hits your products, and audits past entries for duty you can get back. It also includes an AI classification assistant for finding and documenting HTS codes.

Is the tariff calculator free?

Yes. The HTS Hero Tariff Calculator is free and unlimited, with no account. Enter an HTS code and country of origin to see every duty line: the base rate, each Chapter 99 tariff with its legal source, exemptions, trade preferences and fees.

How do I get alerts when tariffs change on my products?

Add your products to the Tariff Tracker as HTS code and country of origin pairs. When a tariff is announced, and again when it reaches the HTS, you get an alert by email, in the app, or in Slack or Microsoft Teams. Alerts are free on 0 imports with any account, no credit card.

Can HTS Hero find duty I overpaid?

Yes. Our tariff audit recalculates each of your past entries with the rules in force on its entry date and flags potentially overpaid duty, missed exemptions and refundable tariffs such as IEEPA.

How much does HTS Hero cost?

The Tariff Calculator is free. The Tariff Tracker is free to start: check 5 imports for savings, run 10 audit checks and get alerts on 0 imports, then from $12 a month, as low as $0.30 per import a month on the largest plan. The classification assistant starts at $39 a month. Monthly plans, no contract, and 15% off with annual billing.

Where does HTS Hero's tariff data come from?

From the official Harmonized Tariff Schedule published by the US International Trade Commission, with every revision's changes entered on the dates they take effect, plus the proclamations, executive orders, Federal Register notices and CBP messages behind them. Every change is logged in a public changelog.

Is HTS Hero a customs broker?

No. HTS Hero is software that calculates, monitors and audits US duty from official sources. We NEVER process entires, corrections, or refunds.
