Terms of Use for HTS Lookup

Last updated: 2026-04-30

These Terms of Use ("Terms") form a legally binding agreement between you ("you" or "user") and the HTS Lookup developer ("we", "us", or "our") and govern your access to and use of the HTS Lookup mobile application and any related services (collectively, the "App"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not download, install, or use the App.

HTS Lookup is a reference utility for searching the Harmonized Tariff Schedule of the United States (HTS / HTSUS). It does not calculate duties or landed costs and does not provide legal, tax, or customs advice.

1. License to Use the App

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to download, install, and use the App on devices you own or control, solely for your personal, non-commercial reference purposes. All rights not expressly granted to you are reserved by us and our licensors.

2. Subscriptions, Auto-Renewal and Cancellation

The App offers optional Premium tiers, including auto-renewable subscriptions (monthly, annual) and a one-time lifetime purchase. Premium unlocks features such as ad-free experience, photo-based lookup, and AI-refined ranking, where available.

3. Refunds

All purchases are processed by the platform store from which you downloaded the App. Refund requests are governed by that platform store's refund policy:

We do not directly process payments and cannot independently issue refunds outside of these platform mechanisms.

4. HTS Data — Reference Only

HTS code descriptions, units, and classification paths shown in the App are reproduced from the publicly available Harmonized Tariff Schedule of the United States published by the U.S. International Trade Commission (USITC). The data is provided for reference only and may differ from the latest official publication.

The App does not calculate duties, customs fees, or landed cost, and does not constitute legal, tax, or customs advice. You are solely responsible for any decisions made based on the information shown. Always confirm the current official schedule and consult a licensed customs broker or attorney before relying on a tariff classification for an actual shipment or filing.

5. AI-Assisted Features

Optional features such as AI-refined ranking, natural-language query translation, and photo-based lookup transmit your input to a third-party large language model provider over an encrypted connection. AI-generated suggestions are probabilistic, may contain errors, and must be independently verified before use. We are not responsible for decisions made solely on the basis of AI-generated output.

6. Acceptable Use

You agree not to:

7. Advertisements

Free tiers of the App may display advertisements served by Google AdMob and its partners to keep the App free to use. Where required by applicable law, a consent prompt is shown before personalized advertising is enabled. Your use of advertising features is also subject to the applicable advertising network's own terms and privacy policies. Premium subscribers do not see advertisements.

8. Intellectual Property

The App, including its design, code, user interface, icons, illustrations, and original content (excluding the public-domain HTSUS data), is owned by us or our licensors and is protected by applicable copyright, trademark, and other intellectual property laws. These Terms do not grant you any rights to our trademarks, logos, or branding.

9. Disclaimer of Warranties

The App is provided "AS IS" and "AS AVAILABLE" without warranties of any kind, either express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, non-infringement, or accuracy of data. We do not warrant that the App will be uninterrupted, error-free, secure, or free from viruses or other harmful components, or that any classification, suggestion, or duty information shown will be accurate, current, or suitable for any particular purpose.

10. Limitation of Liability

To the maximum extent permitted by applicable law, in no event shall we, our affiliates, or our licensors be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or any loss of profits, revenue, data, business, or goodwill, arising out of or in connection with your use of or inability to use the App, even if advised of the possibility of such damages. Our total cumulative liability for any claim arising out of or relating to these Terms or the App shall not exceed the greater of (a) the amount you paid to us for the App in the 12 months preceding the claim or (b) USD 25.

11. Third-Party Services

The App integrates with or relies on third-party services including, but not limited to, Google AdMob, Google Firebase, the platform store (Google Play / Apple App Store), and third-party large language model providers. Your use of these services is subject to their respective terms and privacy policies. We are not responsible for the acts, omissions, content, or policies of any third party.

12. Termination

These Terms remain in effect until terminated by you or by us. You may terminate these Terms at any time by uninstalling the App. We may suspend or terminate your access to all or part of the App at any time, with or without notice, if we believe you have violated these Terms or any applicable law, or to protect the rights, safety, or property of any person. Upon termination, the license granted in Section 1 ends immediately. Sections intended by their nature to survive termination (including Sections 4, 8, 9, 10, 14, and 15) shall survive.

13. Updates to the App

We may release updates, bug fixes, or new features for the App from time to time, and may change, suspend, or discontinue features at our discretion. The App may also periodically download updated HTS data packages to keep classifications current.

14. Changes to These Terms

We may update these Terms from time to time to reflect changes to the App, our business, or applicable laws. The updated Terms will be posted at this URL with an updated effective date at the top of this page. Your continued use of the App after such update means you accept the revised Terms.

15. Governing Law and Disputes

These Terms are governed by and construed in accordance with the laws of the jurisdiction in which the developer is based, without regard to its conflict-of-laws provisions, and without prejudice to any mandatory consumer-protection rights you may have in your country of residence. To the extent permitted by law, any dispute arising out of or relating to these Terms or the App shall be resolved exclusively in the competent courts of that jurisdiction.

16. Privacy

Your use of the App is also governed by our Privacy Policy, which describes what information the App may process and the choices you have.

17. Children

The App is a general-audience reference utility and is not directed to children under 13 (or the equivalent minimum age in your jurisdiction). If you are below the minimum age required to enter into a binding contract in your jurisdiction, you may use the App only with the involvement and consent of a parent or legal guardian.

18. Severability and Entire Agreement

If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will remain in full force and effect. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the App and supersede any prior agreements between you and us relating to the App.
