Steel Safeguards Proclamation (2002)
President George W. Bush invoked the Section 201 trade law to impose tariffs on steel imports. The proclamation also directed Commerce and Treasury to create an import licensing system to monitor steel shipments entering the country.
The licensing system began collecting data on steel imports entering the United States.
The monitoring infrastructure outlived the safeguard measures themselves, evolving into the permanent SIMA system.
The 2026 rule is the latest update to infrastructure created for temporary tariffs in 2002 but kept running for two decades afterward.
