Nvidia’s H200 AI chips have been blocked from entering China, even though the processors were recently cleared for export by the United States, according to reports.
Chinese customs officials have reportedly stopped shipments without giving formal reasons, prompting suppliers to pause production amid uncertainty. At the same time, US rules require the Taiwan-made chips to pass through US testing facilities, triggering a 25% tariff. Analysts say the move adds to growing trade and technology tensions between Washington and Beijing, with no clarity yet on whether China’s action is a temporary measure or an outright ban.
