The Multilateral Alignment of Technology Controls on Hardware Act, or MATCH Act, seeks to fortify U.S. export controls on semiconductor manufacturing equipment and components, recognizing them as critical to national security and the balance of power in advanced computing. The bill emphasizes that adversaries, particularly those engaged in Military-Civil Fusion efforts, exploit gaps in current export control regimes, necessitating robust and aligned international action. It specifically targets entities involved in advanced-node integrated circuit production within "countries of concern," such as China, Cuba, Iran, North Korea, and Russia, to prevent them from accessing critical U.S. technologies. The legislation mandates that U.S. agency heads identify critical semiconductor manufacturing equipment and facilities involved in advanced-node integrated circuit production in these countries. Following this, the bill requires immediate and prioritized diplomatic engagement with allied supplier countries to encourage them to adopt countrywide controls on covered equipment and implement a policy of denial for exports and servicing to identified facilities. This aims to prevent circumvention and ensure a level global playing field for technology controls. Should allied supplier countries fail to implement these aligned controls within 150 days, the U.S. is directed to impose unilateral restrictions. These include establishing U.S. jurisdiction over covered semiconductor manufacturing equipment exported from non-compliant allied countries and requiring licenses with a policy of denial for servicing applicable items at covered facilities. The bill provides for a potential one-time waiver for the 150-day deadline if it serves U.S. national security interests and allies demonstrate concrete steps towards compliance. Annual reports to Congress will detail the scope of controls, diplomatic efforts, and any unilateral actions taken, ensuring accountability and continuous assessment of the control regime. The Act is set to expire five years after its enactment, though prior obligations remain.
