The scouting pattern
Brokers active in Querétaro have confirmed what site-selection consultants have been signaling since Q1: aerospace tier-1s with 12–24 month build timelines are no longer starting their search in the Bajío. Two European suppliers and one Canadian tier-1 have opened active site-selection processes in Coahuila and Nuevo León — states that until recently were treated as automotive-first territory.
The pattern is not a signal that the Bajío has lost the aerospace category. Querétaro remains the anchor of Mexico's aerospace ecosystem — Safran, Bombardier, and the airport cluster are not moving. What is moving is incremental capacity: the plants that would have added a second building, or a new supplier that would have followed a customer into Querétaro, is now weighing a 300-km jump north.
Why the shift is happening
Three forces are converging:
- Land. Newmark México and AMPIP have both flagged that Class-A industrial vacancy in Querétaro fell below 1.4% in the second quarter. Large aerospace plots — 15 hectares and up, with the runway, security perimeter, and utility density the category requires — are not available at any price.
- Skills gravity. Coahuila and Nuevo León have spent a decade building the metallurgy, precision-machining, and composites-adjacent workforce that aerospace shares with automotive. The talent bar is close enough that tier-1s no longer see a discontinuity when they cross into the north.
- Logistics geometry. For suppliers whose primary customer is in the US Midwest or Wichita, Nuevo León shortens the road-freight loop meaningfully. The Bajío's advantage was proximity to the airport clusters; the north's advantage is proximity to the customer.
What to watch
Site selection cycles in aerospace take longer than automotive — six to nine months of due diligence, followed by 12–18 months to build. The decisions being made in the next quarter will not show up as ribbon-cuttings until 2027, which is exactly why they are worth watching now.
The question for state economic-development teams is not whether the Bajío will keep aerospace — it will. It is whether the second wave, the incremental capacity, gets captured by Coahuila and Nuevo León, or leaks to San Luis Potosí and Aguascalientes as they build out their own aerospace tracks. The next three announcements will tell us which way it goes.
