The Bridge Is Ending — And the Permanent Toll Road Is Opening
On July 24, 2026, a hard statutory clock runs out. The 10% global import surcharge that the Trump administration imposed under Section 122 of the Trade Act of 1974 — the emergency bridge erected hours after the Supreme Court struck down IEEPA tariff authority in February — expires by operation of law and cannot be unilaterally extended. For U.S. importers who have spent months managing that flat 10% baseline, the expiry is not a reprieve. It is a transition to a new tariff architecture built on Section 301, a legal authority with no rate ceiling and no time limit. If your sourcing spans Asia, Latin America, or virtually anywhere else on earth, the next 30 days will reshape your landed-cost math in ways that may prove permanent.
How We Got Here: From IEEPA to Section 122 to Section 301
The current tariff situation traces back to a single Supreme Court ruling. On February 20, 2026, the Court ruled 6–3 in Learning Resources, Inc. v. Trump that IEEPA — the International Emergency Economic Powers Act — does not authorize the president to impose tariffs. The decision invalidated the April 2025 "Liberation Day" reciprocal tariffs as well as fentanyl-related duties on China, Mexico, and Canada.
Within hours, the White House invoked Section 122 of the Trade Act of 1974, imposing a 10% across-the-board import surcharge on goods from nearly all countries for 150 days. Section 122 gives the president authority to impose temporary levies of up to 15% to address "large and serious" balance-of-payments deficits, but Congress capped those measures at 150 days unless lawmakers affirmatively extend them. That 150-day window closes on July 24, 2026. Congressional extension is not expected: multiple senators from both parties have gone on record opposing it, and one measure — the Reclaim Trade Powers Act — would eliminate Section 122 authority entirely.
At the same time, the Court of International Trade ruled on May 7, 2026, that even Section 122 was unlawfully applied, because the administration cited general trade deficits rather than the specific balance-of-payments deficits the statute requires. The permanent injunction from that ruling covers only the three named plaintiffs; every other importer continues to pay Section 122 duties while a government appeal to the Federal Circuit proceeds.
What Section 301 Actually Is — and Why It Is Different
Section 301 of the Trade Act of 1974 authorizes the president to impose tariffs and other sanctions in response to foreign acts, policies, or practices that are "unreasonable or discriminatory" and burden or restrict U.S. commerce — even where no violation of international law exists. Unlike Section 122, Section 301 carries no statutory rate cap and no expiration date. Duties imposed under it can remain in effect indefinitely and can be raised without a new investigation.
The administration launched two parallel Section 301 investigations on March 11–12, 2026: one targeting excess manufacturing capacity in 16 major economies, and a second targeting forced-labor enforcement practices across 60 or more trading partners. Both investigations were explicitly designed to produce replacement tariffs before Section 122 expired.
On June 2, 2026, the Office of the U.S. Trade Representative published affirmative determinations in all 60 of its forced-labor investigations, concluding that every major U.S. trading partner has failed to adequately prohibit or enforce bans on imports of goods produced with forced labor. Those 60 economies collectively account for 99.4% of all goods imported into the United States. USTR proposed additional tariffs across two tiers: a 10% rate for economies that have enacted a full or partial forced-labor import prohibition or binding commitments through trade agreements, and a 12.5% rate for all others.
Which Countries Face Which Rates
Under the USTR's proposed forced-labor tariff framework, 15 trading partners are placed in the lower 10% tier. These include Canada, the European Union, Ecuador, Indonesia, Mexico, and Pakistan — jurisdictions that have adopted forced-labor import prohibitions or committed to them through reciprocal trade agreements, but which USTR found are not effectively enforcing those commitments. The remaining 45 trading partners face the higher 12.5% proposed rate. This group includes China, India, Vietnam, Thailand, Turkey, South Korea, Japan, and most others.
The European Union is something of a special case. On July 1, 2026, the EU-U.S. trade deal took effect, moving most EU-origin goods to a 15% all-inclusive tariff ceiling that replaces both Section 122 and the proposed Section 301 rate for the bloc. Steel, aluminum, and a handful of other sector-specific goods remain under their Section 232 rates.
For Brazil, the picture is more complicated still. The administration finalized a separate 25% Section 301 tariff on Brazilian goods on July 15, 2026, citing a range of digital trade and market-access disputes. Whether that 25% rate stacks with any forced-labor Section 301 rate remains unresolved.
What Is Exempt — and What Stacks
The proposed Section 301 tariffs are not applied universally across every product. The USTR published an Annex A of excluded goods largely mirroring existing Section 122 exemptions, covering categories such as certain agricultural products, aviation parts and equipment, industrial inputs, minerals, and pharmaceutical goods. Importers should not assume their products are automatically exempt — a line-by-line review of Harmonized Tariff Schedule classifications against the published Annex is essential.
Goods that already carry Section 232 tariffs — steel at 50%, aluminum at 50%, copper at 50%, automobiles at 25%, and semiconductors at 25% — are carved out from the new Section 301 rates; they do not stack. By contrast, existing China-specific Section 301 tariffs from prior trade actions (ranging from 25% to 100% on covered products) are separate and remain in effect. The excess-capacity investigation covering 16 economies — including China, Mexico, Japan, India, Vietnam, Taiwan, and Bangladesh — has not yet produced proposed tariffs, meaning additional layering above these rates remains possible later in 2026.
Importers sourcing from USMCA-qualifying origins in Canada or Mexico retain their preferential zero-duty treatment on qualifying goods, which is a meaningful competitive advantage given that both countries fall into the 10% forced-labor tier.
What the Data Says About Import Volumes Right Now
The market has been responding to the July 24 deadline for weeks. The National Retail Federation and Hackett Associates' Global Port Tracker projected July 2026 U.S. container imports at a record 2.47 million TEUs — a figure that would top the previous all-time monthly high of 2.4 million TEUs set in May 2022. The driver is not a surge in consumer demand. Ben Hackett, founder of Hackett Associates, was direct: the growth "reflects frontloading ahead of expected tariff increases."
The flip side of that pre-deadline rush is a predicted demand cliff on the other side. Container volumes are forecast to fall to approximately 2.22 million TEUs in August and approach 1.99 million TEUs in September, year-over-year declines of 4.5% and 5.7% respectively. With many importers already having frontloaded inventory earlier this year, the industry may ultimately experience another year without a traditional peak season, with demand shifting around trade policy developments rather than seasonal retail cycles. That reality has tangible consequences for ocean freight rates, warehousing absorption, and trucking capacity in the final months of 2026.
Three Scenarios Every Importer Should Model Before August
Given the uncertainty surrounding both the timing and final rates of any Section 301 announcement, importers should avoid planning around a single outcome. Treat the 10% forced-labor rate as the realistic floor for the 15 economies in the lower tier, and 12.5% as the floor for the remaining 45. Neither figure is a ceiling under Section 301 authority, and the excess-capacity investigation adds a second potential tariff layer for 16 economies. Goods arriving on or after the effective date of any new Section 301 determination will be subject to the new rates — so entries in transit on July 24 warrant close coordination with your broker partner on customs entry timing. On the upside, every importer that paid Section 122 duties should be preserving refund claim rights while that litigation proceeds at the Federal Circuit, even though broad relief is not guaranteed.
