On Sunday, February 22, 2026, U.S. Customs and Border Protection (CBP) issued Cargo Systems Messaging Service (CSMS) Message # 67834313 to clarify that the U.S. government will stop collecting tariffs subject to the International Emergency Economic Powers Act (IEEPA) beginning Tuesday, February 24, 2026. The CSMS message follows the U.S. Supreme Court’s decision on Friday, February 20, 2026, that the IEEPA cannot be used as a statutory basis for levying tariffs (see Update of February 20, 2026). The CSMS message addresses a key question left unanswered by the ruling—when the assessment and collection of IEEPA-based tariffs will end.
The CSMS message implements an executive order signed by President Donald Trump the evening of February 20, 2026, in response to the U.S. Supreme Court’s decision. That executive order terminated various Trump administration actions that had imposed additional duties under the IEEPA but stated that the collection of IEEPA-based duties would cease “as soon as practicable.”
As noted by the CSMS message, other additional tariff regimes, such as those imposed under Section 232 of the Trade Expansion Act of 1962, as amended, and Section 301 of the Trade Act of 1974, as amended, remain in effect.
