Public Tariff Researchin Global Trade

Start with the same official-source measure library, then choose the public search or calculator that fits your task.

Supply Chain & Procurement Leaders

Source-linked tariff research for portfolio decisions

When product, origin, and spend data live in different systems, even a preliminary exposure review takes time. TariffOS provides a public measure library and scenario tools; account-based catalog analysis is available separately.

Common pain points

  • No single view of total duty exposure across the product portfolio
  • Tariff changes surface too late, after they have already impacted margins
  • Sourcing shift decisions take weeks of manual analysis across spreadsheets

Customs Brokers & Trade Consultants

A faster starting point for measure and deadline research

TariffOS helps locate selected Section 301 and Section 232 measures, deadlines, and official publications. Its calculators use user-supplied assumptions and do not replace the HTSUS, rulings, ACE data, or professional classification work.

Common pain points

  • Keeping up with the pace of Section 301/232 modifications and exclusion deadlines
  • Manual duty calculations across multiple HTS codes and trade programs
  • Clients ask about FTA eligibility and you need answers fast

Trade Compliance Teams

A source-linked index for selected measures and deadlines

Use the curated timeline and deadline pages to organize an initial review, then verify the full legal text and product scope in the linked government publication. TariffOS does not automate filings or compliance decisions.

Common pain points

  • Exemption and exclusion deadlines slip through the cracks
  • Classification audits require pulling data from multiple disconnected systems
  • USMCA rules of origin compliance requires constant verification

Importers & Manufacturers

Test landed-cost assumptions before a purchase order

Use the public calculator to combine product value, freight, insurance, and rates you supply. Then check selected tariff exposure and official sources. Results are scenarios, not a complete entry calculation.

Common pain points

  • Supplier quotes don't include duties, so actual landed cost becomes a surprise
  • Tariff changes between order and delivery wipe out expected margins
  • Finding lower-duty suppliers means weeks of manual research

Policy Analysts & Researchers

A structured index into selected primary-source measures

TariffOS organizes selected measures by date, country, status, and recorded HS prefix. It is useful for discovery and cross-referencing, while the linked government publication remains authoritative.

Common pain points

  • Government data portals are slow, clunky, and hard to cross-reference
  • Policy changes are announced across multiple channels with no single view
  • Economic impact modeling requires data from 5+ different sources
