Mexico’s freight peak runs from September to mid-December, driven by Buen Fin, holiday imports, and export year-end, with a smaller secondary peak in May–June. In the peak, spot rates rise 15–40% above the annual average, carriers ration capacity to their best customers, and accessorials bloom. The season is not won in October: it is won in August.

Capacity

Guaranteed volume for guaranteed units.
Trailer on a congested peak-season highway
Capacity is rationed to shippers who do not abuse units or delay payment.

The August savings error

Delaying the tender or dropping base carriers because summer spot is cheap leaves your freight to November spot. Annual compare: contracted rate with capacity almost always beats cheap-contract + panic. Structure in the RFQ guide.

What OCL runs

OCL Cargo is a shipper-side autonomous TMS: agents with computer use build the trip file and reconcile before pay, whether the invoice is from a direct carrier or a 3PL. It can stamp invoice and Carta Porte. Coexists without day-one migration; humans on exceptions. 5–7% pattern when auditing 100%.

Key takeaways5 points
  1. MX peak: September to mid-December; spot +15 to +40%.
  2. Won in August, not October.
  3. Write peak surcharge with number, start, and end.
  4. Do not relax validation: peak is ghost-carrier harvest.
  5. Audit during peak; OCL does not take November off.
