The triangle

One corridor.
Three sets of rules.

Triangle trade isn't the colonial-era history lesson — it's a modern regulatory circuit. Goods flow US ↔ Canada ↔ Mexico, and the compliance regime changes on every leg. A shipment touching all three faces layered obligations no bilateral tool was built to handle.

TTIintelligence layerCACanadaUSUnited StatesMXMexico
01
US → Canada
Manufactured goods, machinery & energy equipment
High USMCA qualification rates make this the cleanest leg — until Section 232 steel and aluminium duties become the compliance pressure point.
USMCA§232 steel / aluminium
02
Canada → Mexico
Raw materials, lumber, auto parts & agricultural inputs
The thin leg of the triangle — less-trafficked, but with more complex duty stacking and fewer off-the-shelf tools to lean on.
CUSMA / T-MECDuty stacking
03
Mexico → US
Auto, electronics, apparel & agricultural output
The highest-volume leg carries the highest stakes: heavy AD/CVD exposure, and USMCA origin rules are exactly where compliance risk concentrates.
USMCA originAD / CVD exposure
How everyone else works
Most platforms are bilateral — US–Canada or US–Mexico. Each leg lives in a different tool, and nothing reconciles the rules where they overlap.
How TTI works
One platform for the full triangle — policy stacking across all three corridors, so a shipment that touches every leg is handled as a single circuit.

The workflow

From shipment to CBP-ready
evidence in seconds.

TTI does the groundwork up front so when the broker is brought in, they're reviewing evidence — not starting from scratch.

01
Enter HS code & origin
Paste the supplier's HS code, select origin country and destination. No account needed — the free tools and the API playground run without a key.
02
TTI stacks every duty layer
MFN base rate + §301 + §232 + any AD/CVD orders. Each layer cited to the exact Federal Register notice.
03
USMCA check runs automatically
Tariff-shift rule, RVC threshold, and CUSMA qualification determined in the same call. Qualifying removes the base rate — Section 232 and AD/CVD are stacked separately and still apply.
04
Export the compliance record
A timestamped CSV with the full duty stack, every Federal Register citation, the policy basis, and the as-of date — the evidence record CBP asks for 18 months later.
The tools

Every tool writes
part of the record.

Purpose-built for the US ↔ Canada ↔ Mexico corridor. Each tool cites its policy basis to the Federal Register and exports what it found, so the answer and the evidence for it leave together.

Build the record

These produce the file a broker signs and a client keeps. Classification reasoning, duty stack, policy basis, and the date it was read.
