ASML denies shipping EUV chip tool to China after US concern

ASML, a key supplier of semiconductor manufacturing equipment, has denied reports that its advanced extreme ultraviolet (EUV) lithography machines may have been sent to China in violation of U.S.-led export controls. U.S. Commerce Secretary Howard Lutnick reportedly conveyed these concerns to senior ASML leaders.

ASML stated that it has never shipped an EUV machine or any specially designed components to China. The company emphasized its consistent adjustment to export control developments to ensure compliance. The Dutch Ministry of Foreign Affairs affirmed that all equipment exports require licenses based on clear rules and control lists, which are strictly enforced.

EUV machines, essential for producing the most advanced chips, are roughly the size of a school bus and weigh 180 tons. ASML is the sole global supplier of this technology. The company expects about 20% of its 2026 revenue to come from permitted sales to China, with a market capitalization around $700 billion.

Separately, a bipartisan bill progressing in the U.S. Congress aims to ban ASML's less advanced deep ultraviolet (DUV) shipments to China.
