Supreme Court Strikes Down Trump Tariffs: What It Means for LA Economy & Ports

A Supreme Court ruling on Friday, February 20, 2026, struck down the majority of tariffs imposed by President Trump, potentially offering some economic relief to Los Angeles’ trade-dependent economy. However, the possibility of reimposed tariffs through other legal means remains a significant factor.

Supreme Court Limits Presidential Tariff Authority

The court’s 6-3 decision determined that Trump did not have the authority to impose tariffs under the International Emergency Economic Powers Act (IEEPA). This ruling effectively rolled back levies that had significantly disrupted international trade. The decision affects up to $170 billion in tariffs collected under IEEPA, including duties ranging from 10% to 50% on goods from China, Canada, and Mexico.

Did You Know? The ports of Los Angeles and Long Beach, which handle nearly a third of the nation’s containerized cargo, saw a surge in traffic during the first half of last year as importers attempted to circumvent the tariffs.

Stephen Cheung, chief executive of the Los Angeles County Economic Development Corp., stated that the tariffs had a “significant impact on our supply chain, on our manufacturers and especially on our port logistics and trade sector.” He believes the ruling will have a significant impact on the Los Angeles economy, but cautioned that it will take time to fully unravel the effects.

Impact on Businesses

The tariffs had negatively impacted a wide range of businesses in Southern California and across the state, including those in agriculture, automotive, home building, technology, and apparel retail. MGA Entertainment, a Chatsworth-based maker of Bratz dolls, noted that over half of its products are manufactured in China. Anawalt, a Malibu hardware and lumber seller, reported that the majority of its lumber comes from Canada and nearly all of its steel products are sourced from China.

Expert Insight: The complexity of the tariffs – varying rates for different countries and commodities – makes it difficult to predict the full extent of their removal. The situation remains unsettled as the potential for new tariffs looms.

Trump Announces New Tariffs

Following the Supreme Court’s decision, President Trump announced his intention to impose a 10% global tariff under the Trade Act of 1974 and pursue additional levies, potentially including a 30% tariff on foreign cars. He signed an order on February 20, 2026, enacting the 10% tax, which will take effect on February 24.

Trump expressed his disappointment with the court’s ruling, calling some justices “unpatriotic and disloyal to our Constitution.”

Uncertainty Remains

Economist Jock O’Connell, international trade advisor at Beacon Economics, suggested that while Trump may have the authority to impose the 10% global tariffs, additional levies would likely require further investigation and trade authorities’ approval. He also anticipates that countries with existing trade deals with the U.S. May seek to renegotiate them in light of the ruling.

Gene Seroka, executive director of the Port of Los Angeles, highlighted the immediate decisions importers now face, questioning whether their commodities are exempt from the struck-down tariffs and considering increased shipments while the exemption holds.
