Not a model's best guess — the Federal Register notice, the proclamation, the CBP message.
Every answer Triangle Trade Intelligence returns carries its citation, the Federal Register notice, the proclamation, the CBP message. Not a model's best guess. 35,124 tariff records across the US, Mexico and Canada, refreshed on a schedule and audited nightly, so what you get today reflects what changed yesterday. Tariff classification, duty calculation, USMCA qualification, and AD/CVD screening — available as an API (47 endpoints) or as 21 embeddable widgets — so a broker can answer a client question in seconds instead of an afternoon.
I am not a customs broker, and Triangle does not pretend to be one. It does not file, and it does not sign. Where the scope of a rule is genuinely ambiguous, the output says so instead of inventing confidence. The licensed judgment stays with the licensed person — the tool just makes sure they are not reconstructing the duty stack by hand at 6pm.
Fifteen years ago I sold my house in Ottawa, packed my office into a Kia and drove south, through Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Belize. I was told I wouldn't make it past the first few months. Mexico kept pulling me back. I married into it. The Yucatán is home now.
So the corridor is not a market I researched. I am Canadian, I live in Mexico, and the third country is the one both of them are trying to sell into.
Before Triangle: ten years running an independent video production practice, translating gnarly enterprise systems into instructions regular people could actually follow, for LinkedIn, Mitel, Sectigo, and the Government of Canada. Tariff law turned out to be another gnarly enterprise system. Same skill, different subject.
Federally incorporated in Canada, infrastructure hosted there too. Some clients care about that a great deal, and others have never once asked.
