Start with a number. The average American household is paying $1,500 more in 2026 than it paid in 2025, entirely because of tariffs. That figure, calculated by the Tax Foundation, does not appear on any receipt. It is distributed across groceries, electronics, car parts, and clothing in increments small enough to be invisible individually and large enough to be consequential in aggregate. It is the hidden tax of a trade policy that has been in constant legal and political motion for eighteen months.

In February 2026, the U.S. Supreme Court ruled that the president could not use the International Emergency Economic Powers Act to impose tariffs. The ruling invalidated the legal foundation on which the entire global tariff structure had been built. What came after is worth understanding carefully, because it is what American businesses and trading partners will be living with for years.

The Replacement Architecture

The administration moved in two steps. First, Trump invoked Section 122 of the Trade Act of 1974 to impose a 10 percent global import surcharge as a bridge. That surcharge expires in July 2026. Second, on June 2, the Office of the U.S. Trade Representative announced proposed tariffs under Section 301 of the Trade Act of 1974, following an investigation into alleged forced labor practices across 59 countries and the European Union.

The proposed rates are 10 percent for 15 trading partners and 12.5 percent for 45 trading partners. A public comment period runs through July 6, with a public hearing on July 7. The timing is not accidental. The Section 301 tariffs are designed to take effect precisely as the Section 122 surcharge expires, maintaining tariff continuity without a gap.

Section 301 matters legally because it is not IEEPA. It has been used successfully by previous administrations, requires a formal investigation and public process, and has survived court challenge before. Section 301 tariff actions are subject to review every four years, making them structurally more permanent than what they replaced.

China: 30 Percent and a 60-Day Clock

The most consequential bilateral development of the past two weeks arrived on June 11. Trump announced a trade framework with China that leaves in place a combined 30 percent tariff rate — 20 percent for fentanyl-related levies and 10 percent reciprocal — while pausing higher tariffs for 60 days. The pause is not a deal. It is an agreement to keep talking.

Sixty days puts the next decision point in mid-August. By then, the Section 301 tariffs will have either been finalized or modified. The Section 122 surcharge will have expired. The EU negotiations, which Commerce Secretary Howard Lutnick described as among the most difficult ongoing, will have either produced a framework or stalled. August is when the current structure either consolidates or fractures.

One variable that could accelerate fracture: Trump announced a proposed 25 percent tariff on countries doing business with Iran. No executive order has been issued. No formal guidance has been published. But the countries implicated — China, India, Turkey, Pakistan, Armenia — include America's largest trading partner and several of its most important ongoing negotiating counterparties. If implemented, the Iran tariff threat would directly contradict the Beijing trade truce announced three days before.

What This Costs

The proposed new tariffs add additional cost and complexity to an already complicated import environment. Companies that spent 2025 rebuilding supply chains around IEEPA tariff rates are rebuilding them again around Section 301 rates. Importers who paid duties under the invalidated IEEPA actions are waiting on refunds that have not yet arrived. Compliance programs built for one legal framework are being retooled for another.

The uncertainty compounds the cost of the tariffs themselves. A business that cannot predict its import costs six months out makes different decisions than one that can. It sources differently, prices differently, and invests differently. That behavioral change, distributed across millions of firms, is part of what the $1,500-per-household figure is actually measuring.

The July Decision Point

Three things expire or resolve in July. The Section 122 surcharge ends. The Section 301 public comment period closes. The EU negotiating deadline arrives.

The Trump administration has concluded or announced tariff agreements with a series of countries, with many still being finalized. The countries that reached deals early are receiving 10 percent rates. The countries that have not are facing 12.5 percent or higher. The incentive structure is clear. Whether it produces deals before July 7 is not.

American trade policy in August will look different from American trade policy today. The legal foundation is stronger than it was under IEEPA. The political situation is more volatile than it has been at any point in this administration. Both things are true at the same time.
