Do you expect prices for everyday goods to rise over the next year?

At the ASCM CHAINge conference in Long Beach, California, Port of Los Angeles Executive Director Gene Seroka described mounting supply chain pressure, saying companies are being asked to pivot repeatedly while their planning horizons narrow. Operators in sourcing, logistics and production-location planning are among those facing shorter decision windows.

Why it matters

Each new trade announcement changes the assumptions behind supply chain plans, forcing companies to revisit sourcing, cost and location decisions more often. The panel tied geopolitics directly to the practical work of moving goods and managing costs.

The source reports no specific figures for shipping volumes, costs or planning timeframes. The panel's assessment rests on qualitative observations from industry leaders rather than measured data.

The players

Gene Seroka

Executive director of the Port of Los Angeles, overseeing one of the largest container gateways in the United States.

Nicholas Burns

Former U.S. Ambassador to China who brings government and diplomatic perspective on trade relations.

Salvador Miñarro

CEO of Darnel Group, a business leader whose perspective informs manufacturing and supply chain operations.

Tosca Derrick

Licensed customs broker and leader in Baker Tilly's global trade management practice, advising companies on cross-border compliance.

The details

Geopolitical moves reshape trade rules and tariffs, which in turn change landed costs and the relative attractiveness of different production regions. Companies that once planned a year or more ahead now must rebuild sourcing and routing assumptions as new announcements arrive. Panelists stressed that this turbulence affects day-to-day logistics as much as high-level policy.

The ASCM CHAINge conference panel took place in Long Beach, California, with remarks published on November 2, 2026.

Market Landscape

The Port of Los Angeles remains one of the principal gateways for U.S. containerized imports, so its executive's read on pressure carries weight across the logistics sector. The panel's emphasis on repeated pivots suggests operators face a sustained rather than one-time adjustment.

Operators should expect to revisit sourcing, routing and production-location assumptions more frequently than their annual planning cycles allow. Procurement and finance teams may need shorter scenario windows that account for repeated trade changes.

The takeaway

Build planning models that run on shorter horizons and flag which trade announcements would change landed cost for your key lanes. Review your sourcing exposure with a licensed customs broker or trade compliance advisor before committing to multi-year contracts.
