The Trump administration has invoked the IEEPA to impose five separate tariff measures — including reciprocal tariffs, fentanyl-related tariffs, tariffs tied to Russian oil imports currently levied on Indian goods, Brazil-related tariffs, and trade agreements negotiated with foreign countries under the law — a sweeping use of emergency powers now under scrutiny by the court.
