Pro Monitor · $29/month

Know when an official tariff source may need another look.

TariffsChart checks saved official-source fingerprints for the HTS codes and routes you manage. When the source changes, Pro sends an email and opens a review item with the retrieval context and broker-handoff trail.

Review

The current official-source fingerprint no longer matches the saved baseline. Re-open the source, compare the retrieved text, and confirm whether the difference affects this SKU before relying on the estimate.

A change signal, not an automatic legal conclusion

A fingerprint change can be wording, layout, metadata, scope, or a substantive policy update. TariffsChart does not automatically determine classification, Chapter 99 treatment, exclusions, AD/CVD scope, admissibility, valuation, or the final duty owed. Every alert stays a review task until verified against the current source and qualified professional advice.

Tariff alert questions

How often are sources checked?

Each monitor can use daily, weekly, monthly, or manual checks. The first check establishes a baseline and does not send a change email.

Will I get duplicate emails?

Identical alert fingerprints are deduplicated. Failed email delivery is recorded and retried up to three attempts.

What happens if I cancel?

No new paid monitor checks run after the current paid entitlement ends. Existing saved records remain subject to the free workspace limits.

Is this an official tariff determination?

No. It is a source-monitoring and recordkeeping workflow. Confirm final treatment with official sources and a qualified customs professional.
