Nvidia suppliers have reportedly paused production after Chinese customs officials blocked shipments of the company’s H200 artificial intelligence chips from entering China, despite the processors being cleared for export by the United States government.
According to a report by the Financial Times, cited by Reuters, parts suppliers halted work amid uncertainty after Chinese authorities informed customs agents that the H200 chips were not permitted to enter the country. Nvidia had reportedly anticipated more than one million orders from Chinese customers, with suppliers preparing for shipments as early as March.
Sources said Chinese officials also summoned domestic technology firms and warned them against purchasing the chips unless absolutely necessary. No official explanation was given, and it remains unclear whether the move represents a formal ban or a temporary restriction. Beijing has not publicly clarified whether the action is intended to protect national security, support domestic chipmakers, or serve as leverage in wider US-China negotiations.
The situation is further complicated by US trade policy. While Washington approved exports of the US-designed, Taiwan-manufactured H200 chips to China, it also required the processors to pass through US testing facilities, triggering a 25% tariff. The same tariff reportedly applies to Advanced Micro Devices’s MI325X chip.
Analysts remain divided on the strategic implications. Supporters of the exports argue they could slow China’s domestic chip development and maintain reliance on US technology. Critics warn the powerful H200 could be used in advanced military or weapons systems, potentially strengthening China’s defence capabilities.
