Chip export fight & smuggling charges
U.S. senators urged a halt to Nvidia AI chip exports to China amid reporting of diversion and smuggling, while the DOJ charged a Chinese national and two Americans in a plot to smuggle export‑controlled AI accelerators — a sign export control friction is intensifying. Customs and enforcement moves are already affecting trade flows and vendor risk assessments. (tomshardware.com) (justice.gov)
Senators Elizabeth Warren (D‑Mass.) and Jim Banks (R‑Ind.) sent a bipartisan letter to Commerce Secretary Howard Lutnick on March 24, 2026, urging an immediate pause and full review of all active export licenses for advanced Nvidia AI chips and server systems bound for China and intermediary destinations in Malaysia, Thailand, Vietnam and Singapore. (banking.senate.gov) The Justice Department on March 25, 2026, charged Stanley Yi Zheng, Matthew Kelly and Tommy Shad English with conspiring to smuggle export‑controlled AI chips by arranging purchases from a California computer hardware company for shipment to China via Thailand. (justice.gov) Federal criminal filings allege the trio sought “hundreds” of Nvidia A100 and H100 GPUs, including a purchase order for 232 Supermicro SYS‑821GE‑TNHR servers with a listed price of roughly $62 million; investigators say the scheme began in May 2023 and a tipster alerted authorities in January 2024. (pcmag.com) A separate indictment unsealed March 19 charges Supermicro co‑founder Yih‑Shyan “Wally” Liaw and two associates with a transshipment scheme prosecutors say moved approximately $2.5 billion in server purchases between 2024 and 2025 — including about $510 million in U.S.‑assembled systems allegedly diverted to China in a narrow window in 2025. (justice.gov) (convergedigest.com) The senators’ letter directly cites Nvidia CEO Jensen Huang’s prior public statements that “there’s no evidence of any AI chip diversion,” saying press reporting available at the time contradicted those assurances and raising questions about relying on vendor attestations for BIS licensing decisions. (banking.senate.gov) Market fallout has been immediate: Super Micro’s stock plunged more than 25–28% the day the indictment was unsealed, wiping several billion dollars from its market value and prompting shareholder litigation and administrative leaves for charged executives.
