The US Supreme Court invalidated the legal foundation for most 2025 tariffs. The same day, the administration invoked Section 122 to impose a temporary 150-day universal 10% rate and launched new Section 301 investigations targeting 16 countries. This is not a rollback. It is a legal reset that keeps tariffs alive under different authority while expanding the scope of trade probes.

The structure of US trade policy stays restrictive, and uncertainty around product-specific tariffs is now higher than before the ruling.
