Members of the American Metals Supply Chain Institute (AMSCI) are raising urgent concerns over the recent decision to double tariffs on imported steel and aluminum, particularly from key trading partners and allies. The abrupt nature of the increase, announced with less than a week’s notice, has left U.S. traders and suppliers facing millions in potential losses on shipments already in transit.

This is worse than the 2018 tariffs,” said one AMSCI member with over 130,000 metric tons of steel currently en route to the U.S. “At least back then we had several months to prepare. Now, businesses are caught mid-shipment, with no guidance, no recourse, and no time.”

The tariffs—justified under Section 232 of the Trade Expansion Act on national security grounds—are facing growing scrutiny, both legally and politically.  The abrupt changes, on again, off again implementation, and changing justifications create significant commercial and policy concerns.

AMSCI warns the current move could destabilize the U.S. metals market, artificially inflate domestic steel and aluminum prices, and undermine international confidence in American trade policy. “We’re already seeing domestic mills issue price increases despite weeks of declining prices,” said another member. “The message this sends to our global partners is damaging: the U.S. market is high-risk and unpredictable.”

AMSCI is calling for immediate clarity on exemptions for in-transit goods, a transparent appeals process, and greater Congressional oversight over future tariff actions. “These decisions shouldn’t be made overnight with no accountability. U.S. manufacturing and supply chains deserve better.”
