TariffSignals — independent tariff exposure monitoring.

TariffSignals is a U.S. tariff exposure monitoring product from SapienCX LLC, a Phase3AI company based in Virginia. We monitor public tariff, trade-remedy, customs, and import-flow data so trade attorneys, importers, CPAs, and compliance teams can see what changed, who is exposed, and what to verify next — before a tariff action becomes an expensive surprise.

Brand identity

TariffSignals is plural. Always.

Our product name is TariffSignals (always plural) and our domain is tariffsignals.com. We are not affiliated with tariffsignal.com (singular) or TariffSignal LLC — that is a separate, unrelated company operating a different product. If you arrived here looking for a bulk tariff calculator, you may be looking for the singular domain. If you arrived here looking for U.S. tariff exposure monitoring and source-linked regime intelligence, you are in the right place.

What we do

Monitoring, issue-spotting, exposure context.

Regime monitoringLive signals across Section 232, Section 301, Section 201, AD/CVD, USMCA, IEEPA-based actions, and retaliatory duties. Each signal carries source citations, status (Effective / Proposed / Monitor / Expiring), affected HTS ranges, and verification checklists tailored to broker, counsel, client-advisory, or importer-exposure review.

Tariff exposure intelligenceU.S. Census trade-flow view of tariff-sensitive imports by HS category, port, origin country, destination state, and NAICS industry. Pairs tariff actions with the actual import volume that would be affected.

Per-category newsCurated commodity-targeted news for steel, aluminum, vehicles, batteries, semiconductors, solar, lumber, apparel, pharmaceuticals, and appliances. Each category exposes a per-HS RSS feed for Pro subscribers to wire into Feedly, Inoreader, Slack, or email.

Client brief generatorGenerate clean, source-linked one-page briefs for clients or internal stakeholders from any signal or domain. Designed for trade-attorney workflow.

What we don't do

Not legal advice. Not customs brokerage.

No HTS classification opinionsHTS classification is fact-specific and requires a licensed customs broker or qualified trade attorney. We point at the right regime and the affected HTS ranges; we don't issue binding classification opinions.

No duty calculationWe do not perform transaction-level duty owed calculations. Duty calculation requires HTS classification, country-of-origin determination, applicable special programs, and current rate tables from the licensed broker filing the entry.

No binding rulingsBinding ruling requests must be filed by importers or their licensed representatives directly with CBP.

No legal, tax, or compliance adviceTariffSignals is informational. Engage qualified counsel for any commercial, legal, tax, or regulatory decision.
