Why brands fulfill from San Diego

San Diego’s freight position is the land border. The Otay Mesa Port of Entry is the busiest commercial vehicle crossing between California and Mexico and the second largest on the US southern border, with more than 1.4 million commercial vehicles crossing northbound in 2019. That year Otay Mesa and Tecate together processed $65.86 billion in bilateral truck trade.

SANDAG and Caltrans broke ground on a new land port of entry, State Route 11/Otay Mesa East, in August 2022. 4 of the 10 firms here operate in Otay Mesa itself, and 3 list cross-docking or transload among their services.

By sea, the Port of San Diego’s 96-acre Tenth Avenue Marine Terminal includes a temperature-controlled warehouse of about 300,000 sq ft and sits minutes from I-5, I-8, I-15 and I-805. The metro exported $24.9 billion of goods in 2024, 19th among US metro areas, and about 217,700 people work in trade, transportation and utilities in the San Diego-Carlsbad-San Marcos metro (August 2026, preliminary).

Measured against the rest of California, the reach is wide: San Diego County and the six-county SCAG region to its north hold more than 22 million people, over half the state’s population. Los Angeles is where that region’s container ports sit, while San Diego’s edge is the truck crossing into Mexico.

Questions to ask a San Diego 3PL

  1. If my goods come north through Otay Mesa, do you handle customs clearance, or do I need a separate broker?
  2. How far is the building that would hold my stock from the border crossing?
  3. Do you run your own drayage, and can you receive full containers from Long Beach or Los Angeles?
  4. If I store alcohol, does the building hold a California Type 14 license?
  5. What is your same-day cut-off, and in which time zone?
  6. Is the published rate card the full price, or do storage and receiving add to it?
