IEEPA tariff timeline
Section 122 expires — MFN and expected Section 301 tariffs apply to postal shipments for the first time
Starting July 24, 2026, the Section 122 flat 10% global surcharge expires for postal shipments. Standard MFN (Most Favored Nation) duty rates apply to postal shipments for the first time, stacking with the expected Section 301 tariff (10–12.5% depending on country of origin — not yet finalized, subject to USTR final action, and may change) and any applicable Section 232 tariffs.
The postal DDP threshold rises from $800 to $2,500 — shipments valued under $2,500 arriving on or after July 24 require prepaid duties. The trigger is the shipment's arrival date, not the transaction date. A shipment quoted before July 24 but arriving on or after July 24 is subject to the new rules.
Posts using Zonos's guarantee (API with Landed Cost guarantee, or Prepay app users) receive a post-specific cutover date 3–9 days ahead of the July 24 arrival cutover — Zonos contacts each post directly. The default cutover for all others is July 21 at 12:01 a.m. EDT.
USMCA can now potentially apply to postal shipments for the first time — but requires a certificate of origin. Details on the process are forthcoming.
CBP issues official guidance — IEEPA duties stop at 12:00 a.m. EST February 24
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.
Trump announces Section 122 tariff raised from 10% to 15%
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.
Trump signs a fact sheet and two executive orders overhauling U.S. tariff policy
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.
Trump plans to sign 10% global tariff executive order — not yet in effect
Watch press briefingFollowing 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.
U.S. Supreme Court rules IEEPA-based tariffs unlawful
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.

Starting July 24, 2026, postal and commercial duty rates converge for the first time. The Section 122 flat 10% surcharge expires. Postal shipments are now subject to MFN rates, the expected Section 301 tariff (10–12.5% by country of origin — not yet finalized), and applicable Section 232 tariffs — the same structure as commercial shipments.
The postal DDP threshold rises from $800 to $2,500. A $1,000 shipment that didn't require prepaid duties before July 24 will require them after. Duty quotes generated before July 24 for shipments arriving on or after July 24 will be recalculated under the new rates.
Most Zonos ecommerce customers use the Zonos guarantee, so Zonos covers any discrepancies during this transition.

What changes on July 24, 2026? The Section 122 flat 10% surcharge expires for postal shipments. Standard MFN duty rates apply to postal shipments for the first time, alongside the expected Section 301 tariff (10–12.5% depending on country of origin — not yet finalized, subject to USTR final action, and may change) and any applicable Section 232 tariffs. The postal DDP threshold rises from $800 to $2,500. Commercial shipment duty treatment is unchanged.
Does Section 301 now apply to postal shipments? Starting July 24, 2026, Section 301 tariffs are expected to apply to postal shipments. Before July 24, postal shipments were subject only to the Section 122 surcharge and Section 301 did not apply to postal clearance. The expected Section 301 rate is 10–12.5% depending on country of origin — not yet finalized.
What is the Section 122 tariff and how is it different from IEEPA? Section 122 of the Trade Act of 1974 gives the president authority to impose tariffs of up to 15% for up to 150 days to address trade deficits or a dollar crisis. Unlike IEEPA, it was specifically designed to authorize tariffs, so the Supreme Court ruling does not affect it. President Trump signed an executive order on February 20, 2026, using Section 122 to impose a 10% global tariff effective February 24, 2026. That surcharge expires July 24, 2026.
I don't know what IEEPA is — does this affect me? If you ship parcels to the U.S., duties on those shipments changed on February 24, 2026, and are changing again on July 24, 2026. IEEPA duties ended February 24 and were replaced by a new 10% Section 122 global surcharge. That surcharge expires July 24, when MFN rates and the expected Section 301 tariff replace it for postal shipments. De minimis duty-free treatment remains suspended.
Are IEEPA duties gone for all U.S.-bound shipments? Yes — as of 12:00 a.m. EST on February 24, 2026. The Section 122 surcharge replaced them through July 23, 2026. Section 232, Section 301, and MFN duties remained in effect for commercial shipments throughout.
What about commercial shipments — do they still have duties? Yes. MFN (most-favored-nation) rates, Section 232 tariffs, and Section 301 tariffs all remain in effect for commercial shipments. Starting July 24, 2026, postal shipments are also subject to MFN, Section 301 (expected), and Section 232 — the same structure as commercial.
Will I receive my invoices as usual? Yes. Invoicing continues normally. Zonos updated duty calculations on February 24 to reflect the Section 122 rate. Zonos is updating calculations again ahead of July 24 to reflect the new rate structure. Note there may be discrepancies for shipments quoted before July 24 but arriving on or after July 24.
Do I need to change my integration or workflow? No. Zonos updates systems automatically. No action is required on your end.
Why might duty still show up after the IEEPA ruling? IEEPA tariffs ended at 12:00 a.m. EST on February 24, but the Section 122 surcharge replaced them effective 12:01 a.m. the same day. Section 232, Section 301, and MFN rates also remained in effect for commercial shipments. Starting July 24, those same rates now apply to postal shipments as well.

IEEPA tariffs struck down, new 10% replacement: what you need to know
The Supreme Court struck down IEEPA-based tariffs, and the administration responded with a deliberate swap — replacing IEEPA authority with Section 122 of the Trade Act of 1974, while a separate executive order preserves the de minimis suspension under its own independent authority. This page explains what it means for your shipments, your invoices, and your workflows.
