U.S. trade policy: new tariffs take effect after Supreme Court ruling
Change
New U.S. tariffs starting at 10% took effect today on about $1.2 trillion of imports for 150 days, following a Supreme Court ruling that struck down key parts of earlier global duties.
Why it matters
The White House said the new tariffs begin at 10% and are justified as addressing “large and serious” U.S. balance-of-payments deficits. The measure applies to roughly $1.2 trillion in imports and is in force as of today, creating an immediate change in landed costs for affected goods. The tariffs are set to last 150 days, introducing a fixed-duration constraint for contracting, inventory, and pricing decisions unless Congress acts to extend. The move follows a Supreme Court decision that struck down key parts of the administration’s earlier global duties, changing the operative legal/policy framework for U.S. import tariffs.
Implications
- • Immediate increase in landed costs for covered imports due to 10% starting rate
- • 150-day duration creates a defined window of tariff exposure unless extended
- • Policy uncertainty shifts to Congressional action on extension after the court ruling
- • Downstream pricing and margin pressure for firms reliant on affected imports
Who is affected
- • U.S. importers of goods covered by the $1.2T tariff scope
- • Manufacturers and retailers with supply chains dependent on tariffed inputs/products
- • Customs brokers, freight forwarders, and logistics providers handling affected entries
- • Foreign exporters selling into the U.S. market in covered categories
