US–Mexico & US–Canada land crossings
Laredo, Otay Mesa, El Paso, Detroit–Windsor and Buffalo–Fort Erie carry the overwhelming majority of North American surface trade. Nearshoring has made these crossings, rather than the ocean ports, the growth constraint for a lot of US import volume.

Inspection-intensity changes cut effective crossing throughput within hours with no infrastructure change, and the queue prices into cross-border truckload immediately.

Crossing volumes are concentrated in a few gateways, so a single crossing's delay becomes a national lead-time problem.

How a problem here propagates
- Inspection-intensity changes cut effective throughput within hours, with no change in physical infrastructure — a policy decision behaves like a capacity cut.
- Crossing queues are highly concentrated: Laredo alone handles a large share of US–Mexico truck freight, so a single crossing's problem is a national one.
- Tariff and customs-procedure changes produce front-loading surges ahead of an effective date, then a slump after it, distorting volumes in both directions.
