US Customs and Border Protection announced that it would cease collecting tariffs imposed under the International Economic Emergency Powers Act effective at 12:01 AM EST after the U.S. Supreme Court ruled the tariffs illegal. This decision comes after more than three days of anticipation following the court's announcement. In its message to shipping companies, the agency indicated that all tariff codes associated with former President Donald Trump's orders related to this law would no longer be enforced starting Tuesday.

The suspension of these tariffs coincides with Trump imposing new global tariffs of 15% under a different legal authority, which is intended to replace those recently deemed illegal by the Supreme Court. However, the Customs agency did not specify why there was a delay in implementing the cessation of other tariffs despite the ruling and did not provide information regarding the possibility of refunds for importers who already paid these tariffs.

The Supreme Court's ruling has broader implications for the legitimacy of tariffs imposed under emergency powers, raising questions about the executive branch's authority in economic regulations. As businesses adjust to these changes, the future of trade policy under the former administration remains a critical topic of discussion as new tariffs are set to take effect, potentially impacting international trade relations and economic conditions in various sectors.
