Questions importers ask before trusting a tariff alert.
Short answers on source freshness, AI limits, AD/CVD risk flags, and what Tariff Sentinel is not.
How to use these answers
These answers are written for tariff monitoring decisions, not for filing an entry. Use them to understand what the tool can flag, what still requires source review, and why a saved-code alert may be useful even when the final duty treatment is not yet clear.
When a question depends on product facts, origin documentation, effective date, or AD/CVD scope, the safe next step is to open the official source and ask a broker or compliance lead to confirm the interpretation before committing to a shipment. If you are not sure where to start, save the HTS code first, then review each alert against the same source hierarchy described in the methodology page.
Is Tariff Sentinel an official government site?
No. It is an independent source-linked monitoring tool that cites official U.S. sources.
Does the calculator provide a binding duty rate?
No. It provides an informational estimate and caveats. Verify before filing.
What happens when a source is uncertain?
The result is marked as a review note, with official links shown so a broker or compliance lead can verify before filing.
Can I save HTS codes without paying?
Yes. You can save a code for source-linked email updates from the code and alert pages.
How often are sources checked?
Federal Register, USTR, and CBP sources are checked daily. Broader HTS refreshes are reviewed weekly.
Why do you show AD/CVD as a risk flag?
AD/CVD scope is product- and source-specific. A risk flag is safer than an overconfident duty number.
