Discover savings
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

Product
Stainless steel double-wall vacuum insulated water bottle, 32oz with leak-proof lid
Candidate headings
- 9617Vacuum flasks and other vacuum vessels, complete; parts thereof other than glass inners
- 7310Tanks, casks, drums, cans, boxes and similar containers, for any material (other than compressed or liquefied gas), of iron or steel, of a capacity not exceeding 300 liters, whether or not lined or heat insulated, but not fitted with mechanical or thermal equipment
- 7323Table, kitchen or other household articles and parts thereof, of iron or steel; iron or steel wool; pot scourers and scouring or polishing pads, gloves and the like, of iron or steel
- 7326Other articles of iron or steel
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 FAQ
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, checks it for antidumping and countervailing duty (AD/CVD) cases, alerts you when a tariff change hits your products, and audits past entries for duty you may be able to 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. A free account adds the AD/CVD check: the antidumping and countervailing duty cases that may cover the import, their deposit rates and the companies named.
How do I get alerts when tariffs change on my products?
With Duty Guard Essentials. Upload your products, each an HTS code and country of origin, and you get an alert when a new tariff affects them: when it's proposed, and again when it's published, with the rate before and after on each product. Alerts come by email, and in Slack or Microsoft Teams on the 100 Products and Scale plans. Every new account gets it free for 7 days, then plans start at $9 a month for 10 products.
Can HTS Hero find duty I overpaid?
Yes. Duty Guard Pro recalculates each of your entries with the rules in force on its entry date and flags duty you may have overpaid, missed exemptions and refundable tariffs such as IEEPA, in seconds. HTS Hero finds and flags; you or your broker file, and you keep 100% of any refund. It's free for 7 days with a new account, then plans start at $49 a month and include Duty Guard Essentials for the same products.
How much does HTS Hero cost?
The Tariff Calculator is free, and every new account gets Duty Guard free for 7 days. After that, Duty Guard Essentials is 10 Products $9 (10 products), 25 Products $19 (25 products), 100 Products $39 (100 products), 500 Products $79 (500 products) a month. Duty Guard Pro is 10 Products $49 (10 products), 25 Products $79 (25 products), 100 Products $149 (100 products), 500 Products $299 (500 products) a month, each with Duty Guard Essentials for the same products included. Over 500 products, we price to your catalog. The classification assistant starts at $39 a month. No contract, cancel anytime, and 15% off with annual billing.
What counts as a product?
A product is one HTS code from one country of origin. The same HTS code from two countries is two products; many shipments of the same product count once. Plans are priced by how many products you have.
Is there a free trial?
Yes. Every new account gets Duty Guard free for 7 days, with no credit card required. The 7 days start when you add your products. When the trial ends, pick a plan to keep everything on; without one, your whole catalog stays free, and alerts and audits stop. Paid plans also come with a guarantee: 30 days money-back on Duty Guard Essentials, and on Duty Guard Pro a full refund if you run 10 audits within 30 days and aren't satisfied. The Tariff Calculator is always free, and you can try the classification assistant free.
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 file entries, corrections or refund claims; you or your broker do.
No more tariff overpayments or surprises.
