From Canal Challenges and Tariff Relief Drive Record Cargo Through Southern California

How could canal challenges and tariff relief affect the Port of Long Beach?

Likely What happens if… A possibility worth considering, not a forecast.

Port of Long Beach may see increased cargo volume from rerouting and tariff relief The Port of Long Beach, part of the San Pedro Bay port complex, could see increased cargo throughput due to two factors. Security and environmental challenges along the Suez and Panama canals are directing more shipments through Southern California. Additionally, the Supreme Court's decision to strike down the majority of tariffs imposed by President Trump provides importers with greater cost certainty, allowing them to replenish inventories at a quicker rate. This combination of rerouting and lower costs is expected to drive trade flows to the complex.

Why it matters

The Port of Long Beach is a critical component of the San Pedro Bay port complex, which handles around 31% of all international waterborne container trade in the U.S. in 2025. Any increase in cargo throughput due to global supply chain shifts or tariff changes directly impacts its operational volume and economic standing as a global competitor for trade and commerce.

The port complex is already operating at high capacity, with the Port of Los Angeles setting a record for September. The ability of the complex to absorb increased shipments from rerouting around the Suez and Panama canals, combined with the cost relief from the tariff ruling, is key to maintaining its status as a major economic engine for Southern California.

What we don't know yet

  • Will the tariff relief be permanent, or could it be reimposed through other means?
  • How will the increased volume from rerouting affect the operational capacity of the San Pedro Bay port complex?

What would change this answer

The Suez and Panama canal challenges worsen significantly.The rerouting of shipments to Southern California would become more urgent and substantial, increasing the likelihood of a stronger positive effect on the Port of Long Beach.
The Supreme Court decision is overturned or tariffs are reimposed.The cost certainty for importers would vanish, potentially offsetting the volume gains from rerouting and reducing the positive effect on the Port of Long Beach.
