$359.9 billion crossed Port Laredo in the 12 months through March 2026, up 3.8% from the year before.March 2026 was the single biggest month in the two-year record, $34.4 billion. Whatever the headlines said, the freight kept moving.

Two years of monthly trade through Port Laredo. The December dips are seasonal; the line held steady through the worst of the 2025 tariff swings.It peaks at the right edge: March 2026 at $34.4 billion, the highest month in the series. The corridor absorbed the noise.

The Infinity Loop: the 90-day cycle of tariff extensions, exemptions, escalations and pauses that replaced steady trade policy.Every quarter, this room re-plans routing, inventory and insurance around a deadline that usually moves. Trade grew anyway; the cost showed up elsewhere.

The Precarity Premium: the cost uncertainty adds before any tariff is paid, capital tied up in buffer inventory, expansions put on hold, defensive restructuring. Uncertainty ran about three times its normal level in 2025.Proving a product qualifies for USMCA costs 1.4 to 2.5% of its value (Federal Reserve), which is why many shippers used to skip certification and just pay the regular duty.

The chaos in three numbers: US imports fell at a 29% annual rate in Q2 2025 as firms stockpiled then froze, and Mexican auto shipments to the US dropped 10.3% in May.Tariffs added 3.1% to core goods prices by February 2026. Through all of it, Laredo’s trade line held while the rest of the system took the hit.

9.9 million jobs across the three countries are exposed to trade disruption: 4.3M in the US, 4.1M in Mexico, 1.5M in Canada. Our Texas Center three-country study.Texas is hit first: 805,000 jobs, more than any other US state. That’s the stake on the table when the review begins.

The review is already underway. USTR opened public comments in September, took testimony in December (about 1,500 filed), and started bilateral talks in March.Round 2 is in Washington June 16-17, about a week out. The agenda gets set before July 1 even arrives.

Mexico rewrote its customs law while attention was on Washington. In force Jan 1: mandatory digital traceability, every clearance auditable in real time, and the Complemento Carta Porte your carriers have to get right.Brokers are now jointly liable for a client’s unpaid duties, and licenses (patentes) drop from lifetime to renewable 20-year terms, recertified every 3 years. The enforcement just moved onto the people in this room.The US tightened its side too: the June 3 order raises the bar to be an importer of record, with bonds, ownership disclosure and stiffer penalties.

USTR’s March instruction to negotiators: cut dependence on imports from outside North America and tighten the rules of origin.What it means for this room: the regional-content threshold goes up, so the bar to qualify for USMCA gets higher right when qualifying matters most.

Certification doubled in 7 months: Mexican-goods compliance went from 49.5% (Dec 2024) to 76.1% (Jul 2025), Canada from 35.5% to 78.7%, and Mexican exporters hit about 85% by January 2026.Why the rush: for years the certification paperwork cost more than the duty it saved, so shippers skipped it. Once tariffs made non-USMCA goods far more expensive, certifying finally paid off, so everyone scrambled to qualify.

The math on one truck: $359.9 billion over roughly 6 million crossings works out to about $60,000 of cargo on the average load.A certified load crosses tariff-free; an uncertified one pays the 10% surcharge, about $6,000 per crossing. Multiply that by the loads you run each week, that’s the real cost of skipping the paperwork.

My position going in: USMCA 2.0. A 21st-century economy still running on 20th-century plumbing. One-off rule tweaks expire; institutions last.Three proposals, each tied to something that already happened in 2026. The pattern for the next three slides: X just happened, so build Y.

X: Mexico rebuilt its customs system on its own, and the US is modernizing CBP and tightening imports (the June 3 order) on its own. Two walls going up in parallel, one on each side.Y: a Binational Customs Agency (proposed with Amb. Gutiérrez): one shared US-Mexico customs framework, security separated from trade facilitation, each country’s sovereignty protected by balanced governance.

X: USTR’s own scoping already puts regional content, supply-chain security and outside dependence on the table, but there’s no standing body to carry it past a single negotiation.Y: a North American Industrial Coordination Council (proposed with Gerry Schwebel of IBC): a trilateral body aligning industrial policy, workforce and innovation. China plans as one system; North America runs three.

X: Mexico just handed customs technology to a new Digital Transformation Agency, AI risk-scoring included, while AI is changing who files what on both sides of the river.Y: NADICI, a North American Digital Infrastructure Coordination Initiative: shared standards for cybersecurity, data governance and AI-enabled trade. These digital rules get written in the next two years either way.

Three institutions, one job each: the customs agency moves goods, the coordination council aligns what we build, NADICI connects the systems.The USMCA only gets formally reopened every 6 years. This review is that opening, the rare chance to put architecture like this on the agenda instead of waiting until 2032.

Four moves before July 1: (1) audit your USMCA certificates against tighter rules of origin, not today’s; (2) get your Ley Aduanera traceability in order and confirm your Mexican broker’s recertification plan.(3) Prepare for the US June 3 order too, importer-of-record status, bonds, ownership disclosure; (4) file comments through your associations and watch the June 16-17 round, where the rules-of-origin signals land first.

Call 1: the review begins July 1 and runs well past 2026. Canada wants a 16-year track, so plan for uncertainty into mid-2027.Call 2, autos tighten first: the recommendations reached Greer’s desk June 1. Required regional content rises from 75%, so today’s certificates get re-graded.Call 3, audits replace tariffs: the courts threw out the emergency (IEEPA) tariffs and the 10% surcharge expires July 24, so what’s left is enforced through your USMCA certificate. The pressure shifts from paying tariffs to surviving audits.

Schuman called borders the scars of history. I see them as living laboratories, where coexistence either works or it doesn’t.What Washington negotiates gets tested here first. Laredo runs the experiment before the continent adopts the result.
