State agencies (existing): technology, management, and budget; statewide strategic tariff response plan; require department to prepare and publish. Creates new act.

HB 5638 requires Michigan's Department of Technology, Management, and Budget to create and publish a statewide strategic tariff response plan for all executive branch departments and agencies by August 31, 2025. The department must consult with every relevant agency during the plan's development. This bill directly affects all state agencies that interact with federal tariff policies, requiring them to have a coordinated response strategy. The plan is procedural, focusing on preparation rather than immediate policy changes.
