Trade never stands still. Neither do we.
For Trade Compliance Teams
At the moment of analysis, TTI documents the classification rationale, the duty stack, and the policy basis. Your broker exports the complete compliance snapshot. That export is the audit artifact. It lives with your team, not with us.
No credit card required. GRI-based reasoning. Federal Register citations on every rate.
Source documents are never stored. Analysis results stay in your account for re-export and deletion on request.
Invoices and certificates are processed in memory and discarded. TTI never stores your source documents. The structured analysis result (HS code, rates, policy basis) stays in your account.
Your broker exports the complete workflow at the moment of analysis: classification rationale, duty stack, policy basis, USMCA determination. They hold the compliance record.
Broker pulls the exported snapshot from their account. Classification reasoning documented. Policy that was in effect at moment of analysis. No scrambling, no reconstruction. Request deletion anytime.

Start FreeNot just the code — the full General Rules of Interpretation chain that produced it. Chapter notes, section notes, exclusion analysis. The reasoning your team can show a CBP officer.
Section 301, Section 232, AD/CVD orders — every rate comes with the FR citation and effective date. The documentation your customs broker needs, delivered automatically.
Most tools give you the MFN base rate. Triangle stacks every applicable layer: Section 301 China tariffs, Section 232 steel/aluminum with melt-origin detection, AD/CVD orders, and transshipment risk flags.
Most classification tools return an HS code and leave the defense to you. When CBP asks "why this heading?" your team needs the GRI chapter note analysis, the exclusion check, the binding ruling search, and you needed it at the time of entry, not 18 months later when the audit arrives.
Triangle documents the reasoning at analysis time. Every result includes the full GRI chain, the confidence score, and the policy basis. Your broker exports this as a timestamped compliance record for your audit file.
