Links to customs authorities, other websites, or future commercial partners are supplied for convenience. We do not control their services or content.

Using the calculators responsibly
The calculators are provided for educational and business planning use. You may enter legitimate shipment and pricing figures, compare scenarios and refer to our published explanations. Do not present our numerical output as a binding customs assessment or an official document issued by a customs authority.
You are responsible for checking product classification, customs origin, effective regulations, valuation and any licenses or tax treatment relevant to your import or export. The website does not undertake customs filing or act as your importer, lawyer, accountant or freight forwarder.
Accuracy, revisions and availability
We try to keep formulas and explanations accurate, but laws, customs fees and service prices can change. A result may be based on incomplete information or a scenario that does not apply to your particular shipment. We may update, correct, replace or remove content without advance individual notification.
We also cannot guarantee uninterrupted uptime, compatibility with every browser, or complete protection from technical failures. If a calculation is material to a financial decision, independently reproduce the arithmetic and obtain official or professional confirmation.
Commercial transactions and third parties
A link to an outside customs agency, freight company, payment provider or adviser is included for information and convenience. We do not control an outside organization’s fees, delivery times, legal advice, data practices or service performance.
If the site later displays advertising, affiliate links or sponsored content, applicable relationships should be disclosed. Any purchase from an outside provider is governed by that provider’s contract and legal obligations, not by our calculator results.
Intellectual property and acceptable reuse
Original explanatory writing, calculator interfaces and code on this website may be protected by applicable copyright and other intellectual-property law. Government material and third-party resources remain subject to their own rules and licenses. Linking to a source does not transfer ownership of its content.
Reasonable personal use and quoting that is otherwise allowed by law are not prohibited by these terms. Unauthorized mass copying, misleading republication of the site as an official customs service, abuse of website infrastructure or interference with other visitors is not permitted.
Security and prohibited activity
Do not attempt to access private administrative areas, compromise site systems, inject malicious code, impersonate other individuals, or interfere with normal operation. Do not use contact forms for spam, threatening messages or unlawful content.
We may take appropriate technical or legal steps to respond to misuse, consistent with applicable law. Protect your own devices and avoid entering confidential business, identity or financial credentials into public calculator inputs or shareable URLs.
Limitation of information and decisions
To the extent permitted by applicable law, the site is provided without an express guarantee that a result is complete, current, fit for a particular contract, or suitable for customs filing. These terms do not override rights or remedies that cannot legally be excluded.
Consequential decisions about imports, shipment contracts, tariffs or regulatory filings require independent verification. If you rely on an estimate without checking the underlying legal assumptions, that may expose you to financial or compliance risk.
Contact and changes to these terms
For questions about using the site or reports of inaccurate information, use contact@tariffcostcalc.com or our Contact page. We may update these terms to reflect changes in the website or applicable requirements.
The date shown at the beginning of the page indicates the version reviewed, and using the site after changes may be subject to the revised terms where legally permitted. The applicable legal framework and mandatory protections depend on the circumstances and jurisdiction.
