TRAFFIX says cross-border freight is tightening as capacity and trade uncertainty rise

TRAFFIX's September 2026 NAX Index shows tougher planning conditions on U.S.-Canada and U.S.-Mexico freight lanes as truck capacity tightens and trade-policy uncertainty builds. The firm says shippers should secure capacity earlier and consider backup options as Canada and Mexico corridor scores both moved above the 50-point threshold.

Why it matters: - Cross-border freight conditions are getting harder to manage for shippers moving goods between the United States, Canada and Mexico. - Tight truck capacity and rising trade-policy uncertainty are pushing up planning risk, especially on U.S.-Canada lanes. - Higher fuel costs are also keeping surcharges elevated.

What happened: - TRAFFIX released its September 2026 NAX Index on Tuesday, showing tighter-than-normal conditions in both the Canada and Mexico corridors. - The Canada NAX climbed to 58. - The Mexico NAX rose to 55. - Both scores were above the Index's 50-point threshold. - TRAFFIX said limited truck availability and trade-policy uncertainty were the main reasons for the shift.

The details: - The NAX Index combines more than 10 economic, freight and trade indicators into a monthly score for the U.S.-Canada and U.S.-Mexico corridors. - The index is designed to give shippers one number to track month to month instead of piecing together separate market signals. - Alex Fuller, vice president of commercial intelligence at TRAFFIX, said shipment volumes are not the issue this month. - Fuller said the bigger problem is lack of truck capacity and added uncertainty on the trade side, especially with Canada. - TRAFFIX expects truck availability to stay tight as Labor Day disruptions and shifting cross-border trade flows work through the network. - Demand has stayed fairly steady, which suggests the current tightness is driven more by capacity and policy than by a jump in shipment volumes. - TRAFFIX said trade-policy uncertainty has increased and is adding cost and shipment-planning questions. - The Canada corridor is drawing special attention because new trade measures are layering more cost and planning complexity onto an already tight market. - The company recommends that shippers review tariff exposure and product classifications for affected U.S.-Canada freight as part of total landed cost. - TRAFFIX also recommends protecting committed carrier capacity for shipments with fixed pickup or delivery dates instead of relying on last-minute coverage. - Shippers should build backup options around critical lanes where a missed pickup could disrupt production or customer commitments. - TRAFFIX says eligible long-haul freight may warrant a look at intermodal options because rail can still offer savings over truckload on some lanes. - Time-sensitive shipments may justify expedited freight when delivery commitments or customer service levels are at risk.

Between the lines: - The index points to a market tightening from the supply side, not from a sudden demand surge. - That means shippers may need to act earlier and plan more conservatively even if overall shipment volumes look stable. - Canada appears to be the more exposed corridor because trade-policy changes are compounding an already constrained market.

What's next: - TRAFFIX expects capacity pressure to remain elevated into the fall. - Shippers moving cross-border freight are likely to keep watching carrier availability, tariff exposure and corridor-specific trade changes. - TRAFFIX publishes the NAX Index monthly with corridor scores, driver analyses, shipper recommendations and historical tracking. - More information is available in the NAX Index. - TRAFFIX also says the company serves the North American transportation industry with truckload, flatbed, intermodal, drayage, expedited, LTL, specialized government services and managed transportation. - TRAFFIX is headquartered in Chicago and employs more than 840 logistics professionals across the United States, Canada and Mexico.
