15% Global Tariff Set to Start This Week

KEY TAKEAWAYS
- Treasury announced a 15% global tariff replacing a 10% universal duty.
- Article 122 permits a 150-day emergency tariff window, creating a hard legal deadline.

Treasury Secretary Scott Bessent said on March 4, 2026, that the administration will implement a 15% global tariff this week and expects to return rates to prior levels within five months by shifting authority to Sections 301 and 232.
15% Tariff Takes Effect and Legal Timeline
The administration will raise the global import duty to 15% during the week of March 4, replacing the earlier 10% universal tariff. This increase relies on Article 122 of the 1974 Trade Act, which allows a temporary emergency tariff for up to 150 days. After that period, further congressional approval or a different legal basis is required.
The Supreme Court struck down the administration’s previous tariff regime in February 2026, invalidating duties linked to the International Emergency Economic Powers Act (IEEPA). This ruling prompted the pivot to Article 122 authority for the current tariff.
Bessent said the administration plans to migrate duties onto Sections 301 and 232 of the Trade Act, which address unfair trade practices and national security, respectively. He described these authorities as slower to implement but legally more durable. He expects tariff rates to revert to prior levels within five months if the shift succeeds.
About $175 billion in unlawfully collected duties remain subject to reimbursement proceedings. The combination of the 150-day emergency window and this large reimbursement exposure creates a tight legal and fiscal timetable that will shape trade policy and refund outcomes in the coming months.
