Spot vs dedicated (Mexico)

Spot versus dedicated is the fundamental commercial split in trucking. Spot freight (carga spot) is tendered load by load at whatever the market bears today; dedicated and contract freight runs on rates and capacity committed over a period, from a simple rate agreement to trucks assigned exclusively to one customer's freight. Cross-border adds a cultural dimension: Mexican freight commerce traditionally leans toward relationships and committed volumes, and Mexican shippers and carriers expect rate-validity windows measured in months, where the U.S. spot market reprices in days.

What this means when you move freight

Match the buying model to the freight's reality, and to the market's. The practical playbook:

• Use spot for irregular volume, new lanes you are still learning, and urgent coverage, accepting that cross-border spot capacity is thinner than domestic and priced accordingly.
• Move to committed rates once a lane shows steady weekly volume; committed cross-border capacity outperforms spot on service quality because carriers plan returns, transfers, and driver rotations around predictable freight.
• Respect the validity-window gap: a Mexican carrier quoting a rate 'good for the season' is behaving normally for their market; clarify explicitly how long a quote holds and what reopens it, fuel, exchange rate, or volume shortfall.

Benchmark either model against real market rate data rather than folklore, and use percentiles to decide how aggressively to price each side of the split.
