China Tightens Indium Export Checks; US Questions ASML on EUV Machine in China
China has increased scrutiny on indium metal exports amid rising AI demand, with buyers reporting more detailed customs checks and delays, though indium is not yet on China's export control list. Separately, the Trump administration has raised concerns with Dutch chip-equipment maker ASML over suspicions that its restricted extreme ultraviolet lithography (EUV) machines may have reached China, which ASML denies. Both issues highlight ongoing tensions over technology exports amid US-China trade restrictions.
