Do the research before you walk in the door

AI models are trained on data that is 18 months old. Our database is scraped every night from 33 live government sources: USTR, CBP, Federal Register, WTO, USITC, and more. AI helps you reason through the data. The database is the truth.

Every answer comes with the evidence trail to defend it. Policy source, Federal Register citation, full duty stack. Your broker reviews and signs off instead of starting from scratch.

HS CLASSIFICATION

Classify any product.
Get the CBP audit trail.

Describe a product in plain language. Get an 8-digit HS code with confidence score, the full GRI reasoning chain, headings considered and rejected, and detailed reasoning your broker can cite in an audit.

ChatGPT can guess an HS code. This proves it's right, with the GRI chain and chapter notes CBP actually asks for.

Every Tariff Classification Has to Pass Two Tests

Most tools only pass one.

The first test is accuracy — is the HS code correct? Every tool attempts this.

The second test is defensibility — if CBP questions the classification, can you produce the reasoning trail? GRI rule applied. Federal Register citation. Decision path documented.

A confidence score doesn't pass the second test. "The tool told us" doesn't pass the second test. A GRI-cited reasoning trail does.

Triangle is built for both.

The Classification Has to Be Right

When context is missing, Triangle asks. It does not guess.

Instant Database Match

When your product matches a known pattern, the answer comes from a curated database — not a language model. Milliseconds, no ambiguity.

Preflight Questions, Not Assumptions

When Section 232 applicability is unclear, Triangle asks you about material composition before classifying. You know your product. Short targeted questions — defensible determination.

You Answer. We Do Not Guess.

For complex classifications, Triangle generates a guided question tree based on your product description. Your answers drive the HS code determination — not an AI inference from an incomplete description.

"The tool told us" is not a CBP defense. "We asked, you answered, here is the reasoning trail" is.

We got flagged in a CBP audit last year. If we'd had this defensibility documentation then, it would have saved us six figures in penalties and legal fees.
