As of July 1, 2026, most EU goods entering the United States pay a 15% all-inclusive tariff ceiling — the rate established by the EU-US trade framework agreed in July 2025 and ratified by both legislative bodies this spring [1]. Aircraft, pharmaceuticals, and semiconductors pay zero. Steel and aluminum pay 50% under Section 232, carved out of the framework. For everything else, the ceiling is 15%, and it does not stack with additional layers.

Forty-six nations do not have that ceiling. Japan, South Korea, India, China, Brazil, Australia, Israel, and 39 others face the proposed Section 301 rate of 12.5% that USTR is adjudicating this week — and that rate is a floor, not a ceiling [2]. It combines with applicable Section 232 steel and aluminum duties, and it is subject to upward revision in the USTR final determination.

The paper tracked the August 1 letter framework yesterday, noting that tariff letters are unilateral rate notices rather than negotiated deals. The EU deal adds the structural context those letters lack: deal-holders pay a ceiling; non-deal-holders face a floor. Two countries can both face roughly 15% on a specific widget, but one faces a rate that cannot increase and cannot stack, while the other faces a rate that is the minimum before sector-specific duties are added. The household-cost outcome depends on which track applies to the specific product from the specific supplier country [3].

Flexport's analysis of the EU deal identifies the practical mechanism for importers. Goods with MFN rates below 15% pay a total of 15% — the MFN rate is included in the ceiling, not added on top. Goods with MFN rates at or above 15% pay MFN only, which means some EU goods with historically high duties effectively see a rate cut [1]. EU importers are also shielded from the July 24 Section 122 expiration — the current 10% emergency global tariff that expires by statute in 17 days — because the EU deal replaced Section 122 for EU-origin goods on July 1.

The 46-nation track does not have that protection. Those countries face both the July 24 Section 122 expiration and the proposed 12.5% Section 301 reset that the USTR hearing this week is finalizing. If USTR meets its July 20 deadline, those countries transition from one regime to another without a gap. If it does not, the gap runs July 24 to roughly August 1, during which the legal basis for the global tariff baseline is uncertain [2].

The paper's frame is not that the EU deal is bad news for the 46 nations. It is that the two-tier structure — ceiling for some, floor for others — is the actual architecture readers need to understand, and most commodity coverage and diplomatic reporting collapses the distinction into a single "tariff level" number that erases it [3].
