Tariff WatchThese terms govern your use of Tariff Watch and Tariff Watch for Business, provided by Attoscale LLC (“we”, “us”). By using the service you agree to them and to our Privacy Policy.
What this service is, and what it is not
Tariff Watch publishes United States import duty rates and computes duty exposure from product data you supply. It is an informational tool. It is not a customs broker, a licensed adviser, or a source of legal advice, and nothing it produces is a ruling or a binding classification.
Classification, valuation, country-of-origin determination and the correctness of any customs filing rest with the importer of record. Duty actually owed on an entry depends on facts we do not have, including the ten-digit statistical classification, declared content where a duty is content-based, preference eligibility, and the entry date. Verify any figure against the cited source before acting on it. If a figure matters to a filing, a refund claim or a commercial decision, confirm it with a licensed customs broker or customs counsel.
Accuracy, and its limits
We take correctness seriously. Every rate we publish is traced to an official source document, carries the date that document was published and the date we last verified it, and is withheld rather than estimated where it cannot be verified. We publish our known limits on the methodology page and update them as they change.
Even so, tariff rates change frequently and sometimes without notice, official sources themselves lag and occasionally contradict one another, and automated extraction can be wrong. We do not warrant that any rate is accurate, current or complete. Where a rate materially affects you, check it against the source we cite.
Who can use the service
You must be at least 18 and able to form a binding contract. If you use the service on behalf of a company, you confirm you are authorised to bind it, and “you” means that company.
Your account and your data
You are responsible for the security of your account credentials and for activity under your account. Tell us promptly at conor@attoscale.io if you believe an account has been compromised.
You keep all rights in the product, supplier and entry data you upload. You grant us a limited licence to process it solely to operate the service for you as described in the Privacy Policy. We do not sell it, and we do not use your uploaded data to train models. You are responsible for having the right to upload what you upload.
The public data, and reuse of it
Rates and the underlying source citations are drawn from United States government publications, which are not themselves subject to copyright. Our compilation, structure, commentary and presentation are ours.
You may quote and reuse the rate data, including through our public JSON endpoints, on these conditions: attribute Tariff Watch and link to the page or endpoint you took it from, include the retrieval date, and do not present the figures as your own verification or as authoritative. Do not remove or obscure the provenance that accompanies a rate. We ask for the retrieval date specifically because a tariff figure without one cannot be checked and quickly becomes misleading.
The public endpoints are rate limited. Do not circumvent those limits, scrape the site in a way that degrades it for others, or resell bulk access to the data as a substitute product.
Acceptable use
- Do not upload malware, or files designed to exploit a parser or a spreadsheet.
- Do not attempt to access another customer’s data, or probe, scan or test the security of the service without our written permission.
- Do not use the service to break the law, including customs, sanctions and export control law.
- Do not misrepresent our output as a customs ruling, a broker’s opinion, or professional advice.
We may throttle, suspend or terminate access that threatens the integrity of the service or breaches these terms.
Plans, billing and cancellation
Paid plans are billed in advance through Stripe on the interval shown at checkout. Prices and the limits attached to each plan are shown on the pricing page. Fees are charged to the payment method on file and renew automatically until cancelled.
You may cancel at any time from your account settings; cancellation takes effect at the end of the current billing period and the service continues until then. Fees already paid are not refunded except where required by law or where we have failed materially and not fixed it within a reasonable time after you tell us. We may change prices on 30 days’ notice, effective at your next renewal.
Availability
We do not offer an uptime guarantee. We may change, suspend or discontinue features. Where a change materially reduces what a paid plan provides, we will give reasonable notice and, if you do not want to continue, refund the unused portion of the period you have paid for.
Disclaimers
The service is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not warrant that the service will be uninterrupted or error free, or that any figure it produces is correct. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.
Limitation of liability
To the fullest extent permitted by law, Attoscale LLC and its officers, members and partners will not be liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost data, duties or penalties assessed, refunds not obtained, or business interruption, arising from or relating to your use of the service, including reliance on any rate or computation it produces.
Our total liability for all claims relating to the service will not exceed the greater of the amount you paid us in the twelve months before the claim arose, or one hundred US dollars. Nothing in these terms limits liability that cannot be limited by law, and nothing relieves you of responsibility for your own customs filings.
Indemnification
You agree to indemnify and hold Attoscale LLC harmless from claims, damages and expenses, including reasonable legal fees, arising from your misuse of the service, your breach of these terms, or a customs filing you made in reliance on output you did not verify.
Termination
You may stop using the service at any time. We may suspend or terminate access for conduct that breaches these terms or threatens the service. On termination you may export your data for 30 days, after which we may delete it. Sections that by their nature should survive termination survive it.
Governing law and disputes
These terms are governed by the laws of the State of Texas, without regard to conflict-of-law rules. Before filing any claim, contact us at conor@attoscale.io so we can try to resolve it informally. Any dispute that cannot be resolved informally will be brought exclusively in the state or federal courts located in Texas, and you consent to their jurisdiction and venue.
Changes; miscellaneous
We may update these terms. Material changes will be reflected here with a new date, and for account holders we will give notice by email before they take effect. Continued use after a change constitutes acceptance. If any provision is unenforceable, the rest remains in effect. You may not assign these terms; we may assign them in connection with a merger, acquisition or sale of assets.
