Officials at the ports of Los Angeles and Long Beach welcomed the 90-day pause on 145% tariffs on Chinese imports but cautioned that uncertainty remains as trade negotiations continue.

Cargo volumes at both ports have already slowed, with the first vessels arriving from China subject to the steep tariff. While the temporary reduction lowers the rate to 30%, concerns persist over its impact on trade.

"The 90-day pause and reduction in tariffs is welcome news to consumers, American businesses, workers, and the supply chain," said Gene Seroka, executive director of the Port of Los Angeles. 

"Even with this announcement, tariffs remain elevated compared to April 1."

Mario Cordero, CEO of the Port of Long Beach, echoed the concern, emphasizing the financial burden on shippers.

"So sometimes on the low-value type of cargo, that's still a lot of money for the average shipper," Cordero said at a news conference on international commerce.

Seroka urged the U.S. and China to work toward a long-term agreement before the pause expires. 

"To avoid further uncertainty and disruption of trade, both sides should work together swiftly toward a long-term agreement. Additionally, it's important for the United States to work with other nations to reduce tariffs," he said.

Cordero also pointed to uncertainty surrounding tariffs on imports from Vietnam and Indonesia, which are set to rise after July 8. "So, what happens after July 8? We don’t know any answer to that question," he said.

Vietnamese imports could face tariffs of up to 46%, while goods from Indonesia may see a 32% tariff increase.
