Even as USTR Jamieson Greer was telling reporters in Paris that a deal is a deal, his own office had released a document the day before creating a structural problem. The Section 301 forced labor tariffs technically stay within the 15% cap negotiated with the EU at Turnberry and with Japan. But a second Section 301 investigation – targeting structural manufacturing surplus in China, the EU, Japan, South Korea, Mexico, Taiwan, and nine others – is weeks from completion and carries no such constraint. Senior trade officials inside the administration worry the cumulative tariff stack could breach the bilateral deals in ways the original agreements never explicitly anticipated. YourDailyAnalysis identifies this internal tension as the most underreported aspect of the current tariff architecture.
The Supreme Court struck down Trump’s IEEPA-based global tariffs in February, ruling 6-3 that IEEPA does not include tariff authority without explicit Congressional delegation. That ruling created an estimated $150 billion hole in tariff revenue and forced refunds. Section 301 carries no cap on tariff level or duration once a determination of unfair trade practice is made. The bilateral deal caps constrain what Washington promised, not what the statute allows.
The Turnberry deal’s language is the critical variable. Greer said the agreement acknowledged the U.S. could impose tariffs up to a certain level. EU Trade Commissioner Maros Sefcovic said the European side understands the deal as an all-inclusive 15%. If the overcapacity Section 301 action results in tariffs that combined with forced labor tariffs push effective rates above 15%, the EU’s interpretation and Washington’s are in conflict. The reporters at YourDailyAnalysis note this conflict has no formal arbitration mechanism in the Turnberry text.
The EU’s position is that it has a market-driven economy and does not contribute to structural excess capacity. That argument is not legally neutral under Section 301. Brandon Farris, executive vice president of the Steel Manufacturers Association, told a USTR hearing that EU excess steelmaking capacity is nearly 85 million metric tons, nearly matching U.S. steel output.
The Section 122 expiry date is the forcing function. The 10% global baseline tariff authority expires on July 24 unless Congress extends it. Greer has said the overcapacity probe will be complete before then. If both Section 301 actions result in tariffs collectively exceeding 15% for EU or Japanese imports, the administration will face a choice: accept that the bilateral deals are breached, or argue the cap applies only to the forced labor tranche. The analysts at YourDailyAnalysis assign the second interpretation as the more legally convenient path, but note the EU would contest it.
Sefcovic expected the European Parliament to approve the Turnberry deal. That approval assumes the deal delivers what was negotiated. A cumulative tariff rate above 15% would fracture that approval timeline. German export associations have already expressed concern about the layering of forced labor tariffs on top of existing duties.
The administration could argue that Section 301 tariffs responding to specific identified practices constitute a justified category not covered by the bilateral cap. Trade law scholars note this has textual support – Section 301 has withstood prior court challenges because it responds to specific findings. But it would require the EU to accept a reading that makes the 15% cap meaningless. YourDailyAnalysis positions this as the argument most likely to be tested in litigation if the overcapacity tariffs push effective rates above the cap.
The political economy runs in different directions simultaneously. Steel manufacturers want more tariffs. Technology companies importing components from the EU and Japan want the caps to hold. The administration has already shown surgical flexibility – it cut tariffs on farm and construction equipment to 15% from 25% through end-2027 to provide relief for farmers squeezed by higher fuel costs.
The test arrives by mid-July. When the overcapacity Section 301 determination lands, the actual tariff rates will clarify whether the bilateral deals serve as real caps or as political assurances with limited legal effect. Your Daily Analysis spells out the two scenarios defining the second half of 2026 trade policy: the caps hold and the bilateral framework survives, or the caps are exceeded and the entire deal-making exercise of the past year is revealed as non-binding in the ways that matter most to trading partners.
