Trump’s Tariff Scope Shifts, Pharmaceuticals Eligible for Exemption as U.S. Supreme Court Case Could Trigger Billions in Refunds

The U.S. Supreme Court announced it would fast-track a challenge to President Donald Trump’s tariff regime, scheduling oral arguments for early November. The justices’ decision places Trump’s sweeping “reciprocal” tariffs—ranging from 10% to 50%—under direct legal scrutiny.

Days earlier, on September 5, Trump had signed an executive order (EO) revising the scope of tariff exemptions. The move was both political and economic, adjusting how certain goods are treated at the border and signaling flexibility toward allied countries. Yet it does not change the central question now before the Court: whether the president had the legal authority to impose such tariffs in the first place.

Scope of New Executive Order on Exemptions

The September 5 EO offers zero-tariff treatment for certain goods from countries that sign reciprocal trade and security agreements with the United States. It identifies more than 45 product categories—including nickel, graphite, gold, and pharmaceutical compounds—as eligible for exemption.

The order also carves out a new scope, with exclusions for specific agricultural products, aircraft components, and generic pharmaceutical ingredients, while removing exemptions on some aluminum hydroxide, resin, and silicone products, making them newly subject to tariffs. These changes took effect on September 8.

White House officials said the order gives trade agencies—including the U.S. Trade Representative, Commerce Department, and Customs—the power to waive tariffs automatically when a partner country signs a qualifying deal, without requiring a new directive from the president. Trump has emphasized that tariff relief will depend on the “scope and economic value” of a partner’s commitments, alongside U.S. national interests.

Legal and Financial Stakes: U.S. May Have to Refund Half the Tariffs if SCOTUS Rules Against Trump

In his first seven months in office, Trump imposed sweeping tariff increases aimed at reshaping the global trading system, reducing U.S. trade deficits, and pressuring trading partners in negotiations. Treasury Secretary Scott Bessent has warned that if the Court rules against the administration, the U.S. may need to refund roughly half of collected tariff revenues. Trump has warned that unfavorable rulings could force Washington to unwind trade deals with allies such as the European Union, Japan, and South Korea.

The administration has relied on the International Emergency Economic Powers Act (IEEPA) of 1977 to justify its tariff strategy, while federal appeals courts and the Court of International Trade have questioned whether that law provides authority for sweeping tariff measures. The Supreme Court’s accelerated review ensures that this dispute will be resolved within months.

Impact of New Scope on Key Partners: Japan, EU, and Switzerland

The order aligns with agreements Washington has struck with major trading partners. In Japan’s case, an executive order on September 4 implemented a framework largely parallel to the European Union’s arrangement. Both deals impose a baseline 15% reciprocal tariff on most goods, with zero tariffs applied where the most-favored-nation duty already meets or exceeds that threshold. Retroactive application to Japanese imports entered after August 7 underscores the administration’s attempt to stabilize terms quickly.

Switzerland, which faces a 39% tariff on gold imports due to the absence of a trade pact, could benefit if it secures a reciprocal deal. Gold bullion, powders, and leaf now appear on the exemption list, reflecting pressure from sectors dependent on Swiss imports.

For the EU, the September order reaffirms earlier concessions while signaling possible further exemptions on natural resources and pharmaceuticals, pending negotiations. European officials have framed these measures as partial relief but remain concerned about broader instability if the Supreme Court invalidates Trump’s tariff authority.

China: A Strategic Rival Outside the Framework—New Scope Does Not Apply

China remains excluded from the reciprocal tariff framework, showcasing its position as Washington’s trade rival. The administration continues to classify Chinese imports—from rare earth elements to advanced electronics—as sensitive under national security provisions.

Beijing has criticized the exemptions as favoring U.S. allies while entrenching decoupling. Chinese exporters of graphite and neodymium magnets, both covered in the September order, risk losing market share to competitors in countries negotiating reciprocal deals with Washington. At the same time, China’s own tariff retaliation—focused on agricultural imports such as soybeans and pork—continues to disrupt U.S. farmers.

Analysts note that if the Supreme Court invalidates Trump’s use of IEEPA, China may gain leverage in any future negotiations by pointing to the legal fragility of U.S. measures. Until then, China appears committed to diversifying supply chains through domestic production and Belt and Road partners rather than pursuing tariff relief from Washington.

India: Balancing Opportunity and Pressure

India occupies a middle ground. While not yet part of a reciprocal framework, New Delhi has positioned itself as an alternative supplier of key minerals and pharmaceuticals listed in the U.S. exemption order. Nickel, graphite, and generic drug ingredients represent areas where Indian exporters could benefit if a bilateral deal is reached.

At the same time, India faces pressure to align more closely with U.S. trade and security priorities. Domestic industries worry that agreeing to reciprocal tariff concessions could expose Indian manufacturers to U.S. competition in sensitive sectors such as agriculture and small-scale industry.

Indian officials have publicly welcomed the prospect of sector-specific carveouts but remain cautious about broader commitments. Observers see potential overlap with the U.S.-India Strategic Trade Dialogue, which has already addressed pharmaceuticals, critical minerals, and defense technology cooperation. The September order could accelerate these discussions, especially if India seeks to capitalize on China’s exclusion.

Global Ripple Effects: Postal Traffic Collapse, Supply Chains Shift

Trump’s policy continues to ripple through global supply chains. The United Nations postal agency recently reported an 80% collapse in postal traffic to the United States after Washington ended the de minimis exemption for low-value imports. Developing economies reliant on small-parcel exports, including parts of Southeast Asia and Latin America, report mounting costs and reduced access to U.S. markets.

In Asia, South Korea faces uncertainty. Although Seoul has been in talks for a reciprocal framework, the possibility of tariffs being unwound by court decisions clouds business planning. Meanwhile, resource-rich countries such as Australia and Canada see opportunities: nickel, rare earths, and pharmaceutical precursors fall under categories eligible for exemption if reciprocal agreements are secured.

In Latin America, agricultural exporters in Brazil and Argentina watch closely. The order explicitly notes exemptions for goods not produced in sufficient quantity within the U.S., raising prospects for soy, beef, and specialty crops. However, the lack of a transparent exclusion process complicates negotiations.

What Comes Next

The dual tracks of executive action and judicial review leave global trade partners in limbo. While Trump’s orders expand the menu of possible exemptions, the Supreme Court’s ruling could reshape the entire foundation of his tariff program.

If the Court upholds his use of IEEPA, aligned partners may rush to finalize reciprocal deals to secure access. If it strikes down the policy, Washington may be forced to refund billions, renegotiate agreements, and recalibrate its trade strategy.

For now, industries from metals to pharmaceuticals and agriculture are recalculating supply lines. The coming months—marked by legal rulings and diplomatic bargaining—will determine whether the U.S. tariff system hardens into a permanent feature or collapses under judicial scrutiny.
