Supreme Court Tariff Case Could Reshape Chemical Import Rules for Years
Supreme Court Tariff Case Could Reshape Chemical Import Rules for Years
The Case
The Supreme Court is reviewing two consolidated lawsuits — Learning Resources v. Trump and Trump v. V.O.S. Selections — challenging tariffs imposed by President Trump in April 2025. The central question: can the president invoke the International Emergency Economic Powers Act (IEEPA) to impose tariffs on imports?
Trump declared two national emergencies to justify the levies: illicit drug flows into the US and alleged lack of reciprocity in bilateral trade. IEEPA historically authorized sanctions on international commerce, but opponents note the law contains neither the word "tariff" nor "levy." Previous presidents relied on different statutes — the Trade Expansion Act of 1962 and Trade Act of 1974 — which require investigations and specific procedures before imposing duties.
Impact on Chemical Companies
The chemical sector faces mixed consequences. The White House excluded many large-volume chemicals from tariffs, including polymers, petrochemicals, and glyphosate. However, targeted segments are directly affected:
- Metals used as catalysts — essential for chemical processing and manufacturing
- Imported pesticides — facing added cost pressure
- Agricultural herbicide dicamba — combined duties of 56.5% from China and 43% from India, layered on existing levies
Companies are responding by seeking alternative suppliers in lower-tariff countries, though this involves complicated logistics, regulatory re-qualification, and supply chain restructuring.
Beyond Tariffs: Regulatory Authority at Stake
The ruling's implications extend well beyond import duties. During oral arguments, Justice Gorsuch asked whether a future president could "impose a 50% tariff on gas-powered cars and auto parts to deal with the unusual and extraordinary threat from abroad of climate change." The Solicitor General responded it was "very likely that that could be done."
The case also touches the major questions doctrine, which requires Congress to explicitly authorize agency actions with vast political and economic significance. A ruling in favor of broad presidential authority could affect how the EPA, OSHA, and other agencies regulate chemicals — potentially bypassing Congressional authorization requirements that have traditionally shaped chemical regulation.
What's Next
The Supreme Court will decide by June 2026. Companies that have already paid tariffs on affected products may be entitled to refunds if the Court rules against the government — those refunds would be processed through customs entry documentation.
For chemical buyers, the practical advice is straightforward: document your import costs carefully, maintain records of duties paid, and watch for the ruling. Whether tariffs stand or fall, the supply chain disruption is already priced into the market.
Alliance's Take
Trade policy uncertainty is nothing new for the chemical industry, but this case is different — it could fundamentally change how import duties are imposed on chemicals and raw materials for years to come.
