IEEPA tariffs struck down, new 10% replacement: what you need to know

CBP issued official guidance confirming that all IEEPA-based duties will stop being collected as of 12:00 a.m. EST on February 24, 2026. Effective 12:01 a.m., those rates are replaced by the new 10% Section 122 global surcharge established by last Friday's executive order. For all practical purposes, this is a rate swap happening overnight.

Zonos will update its Landed Cost calculations at 12:00 a.m. EST tonight to reflect these changes. Section 232 and Section 301 tariffs remain in effect and are unaffected by this change.

Note: President Trump has announced via Truth Social his intent to raise the Section 122 rate to 15%, but no signed order has been published — CBP guidance is pending.

President Trump posted on Truth Social announcing that, following the Supreme Court ruling, he is raising the Section 122 worldwide tariff from 10% to the maximum legally allowed rate of 15%, effective immediately. He stated that the administration will determine and issue new permissible tariff rates in the coming months.

This is just an announcement — CBP implementation guidance and a formal executive order have not yet been issued. Zonos will update this page as soon as enforcement guidance is available.

President Trump signed a fact sheet and two executive orders on February 20, 2026, replacing the prior IEEPA-based tariff regime with a new framework:

• Prior IEEPA tariffs terminated (Executive Order) — Additional ad valorem duties previously imposed under IEEPA are ended, including country-specific duties on China, Canada, Mexico, Brazil, Russia, Cuba, Iran, and Venezuela, and the reciprocal tariffs. Section 232 and Section 301 tariffs are unaffected.

• 10% Section 122 import surcharge (White House Fact Sheet) — A temporary 150-day, 10% ad valorem duty on all imported articles, effective February 24, 2026 at 12:01 a.m. EST. Excluded categories include certain critical minerals, pharmaceuticals, electronics, passenger vehicles, aerospace products, and (at least for commercial shipments) USMCA-compliant goods from Canada and Mexico.

• De minimis suspension continued (Executive Order) — The most consequential action for cross-border e-commerce. This EO explicitly continues the suspension of duty-free de minimis treatment for all shipments regardless of value, country of origin, or mode of transportation; continues the qualified party process; resets the duty rate for international postal shipments to the 10% Section 122 rate (replacing previous IEEPA-based rates); and confirms CBP has the systems in place to collect these duties. Effective February 24, 2026 at 12:01 a.m. EST.

Following the Supreme Court ruling, President Trump stated he would sign an executive order imposing a 10% global tariff on all nations under Section 122 of the Trade Act of 1974 — a separate legal authority that gives the president power to impose tariffs of up to 15% for up to 150 days and is unaffected by the Supreme Court ruling — on top of existing tariffs.

What this means for you right now: nothing has changed. The order has only been announced — it has not been signed, published in the Federal Register, or enforced. Until the executive order is signed and CBP issues guidance, no Section 122 tariffs apply at the border. Zonos will update this page as soon as the order is signed and enforcement guidance is available.

The U.S. Supreme Court issued a landmark ruling declaring tariffs imposed under the International Emergency Economic Powers Act (IEEPA) unlawful. The court found that IEEPA does not grant the president authority to impose tariffs.

CBP has not yet issued updated enforcement guidance — IEEPA tariff rates remain in effect at the border until further notice. Zonos is in close contact with CBP and will update this page as soon as enforcement guidance is issued.
