Start FreeWhat Triangle gives your team that lookup tools don't
GRI reasoning on every result
Not 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.
CBP defensibility score
85%+ means audit-ready. Below that, Triangle flags the ambiguity and tells you what evidence would raise the score. No more classifying with fingers crossed.
Federal Register citation on every policy layer
Section 301, Section 232, Section 122, AD/CVD orders — every rate comes with the FR citation and effective date. The documentation your customs broker needs, delivered automatically.
Full duty stack: MFN + 301 + 232 + AD/CVD
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.
The CBP audit problem isn't the code. It's the evidence.
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 locks the reasoning at classification time. Every result includes the full GRI chain, the confidence score, and the policy snapshot, timestamped and exportable for your audit file.
