A bipartisan group of U.S. lawmakers introduced the Multilateral Alignment of Technology Controls on Hardware Act, or MATCH Act, in early April, targeting the sale and servicing of advanced chipmaking equipment to China.

The bill, filed as H.R. 8170 in the House and with a companion in the Senate, would impose country-wide prohibitions on exports of DUV lithography systems to China, designate five Chinese semiconductor firms as restricted entities by statute, and give U.S. allies 150 days to adopt equivalent controls before Washington expands the Foreign Direct Product Rule unilaterally.
