Trump Tariffs Remain in Place Despite Supreme Court Ruling

Despite a recent Supreme Court ruling deeming President Trump’s previous tariffs illegal, U.S. Importers continue to pay duties on goods entering the country. The ruling, issued on February 23, 2026, struck down tariffs imposed under the International Emergency Economic Powers Act (IEEPA), but U.S. Customs and Border Protection (CBP) has yet to update its systems to reflect the change.

Supreme Court Ruling and Initial Response

The Supreme Court ruled that President Trump had exceeded his authority when imposing tariffs on a wide range of goods, finding that the IEEPA was not intended for such broad trade measures. Reuters reports that Senate Democrats have introduced a bill to force refunds of these tariffs.

However, the immediate impact of the ruling has been limited. According to CNBC, approximately 211,000 containers of goods, valued at $8.2 billion, arrived in U.S. Ports between Friday and Sunday and were still subject to the IEEPA tariffs. CBP acknowledged the ruling but stated it is “working with other government agencies to fully examine the implications” and will provide updates “as soon as it becomes available.”

New Tariffs Imposed Under Alternative Authority

In response to the Supreme Court’s decision, President Trump invoked another law to reimpose a 10 percent tariff on goods imported from all countries. This new scheme, unlike the previous tariffs, is limited to a maximum duration of 150 days and requires Congressional approval for extension. The tariff rate is also capped at 15 percent under this authority. The Council on Foreign Relations details this shift in strategy, noting that Trump announced he would utilize Section 122 of the Trade Act of 1974, which addresses balance-of-payments deficits.

Impact on Trade and the Port of Oakland

While Trump’s initial tariffs sparked fears of economic disruption, the Port of Oakland experienced only a minor decline in trade volume in 2025 – a decrease of just 0.4 percent year-over-year. The Mercury News reports that the port proved adaptable, maximizing efficiency and maintaining relationships with shipping companies. The tariffs were ultimately less severe than initially announced.

Despite this resilience, the situation remains fluid. Trump has warned countries with existing trade agreements that any attempts to circumvent the new tariffs could result in even higher levies.

• President Trump has reimposed a 10 percent tariff using a different legal authority (Section 122 of the Trade Act of 1974).
• The new tariffs are capped at 15 percent and have a 150-day limit, requiring Congressional approval for extension.
• The Port of Oakland demonstrated resilience to the initial tariffs, experiencing only a minimal decline in trade volume.
