US weighs per-customer cap on Nvidia H200 exports to China

Washington considers tighter throttle on AI chips

The US government is reportedly considering capping sales of Nvidia’s H200 AI accelerators to any single Chinese customer at 75,000 units, a fresh constraint on the chipmaker’s tentative return to a crucial market. People familiar with the deliberations said shipments of Advanced Micro Devices’ MI325 chips would count toward the same per-customer ceiling. Total shipments to China could still reach as many as 1 million units, it has been reported, but the lion’s share of demand comes from a handful of buyers. Nvidia shares slipped almost 1% in late trading on the news, hitting a low of US$181.

China’s AI giants would be squeezed

The proposed limit is less than half of what Alibaba Group Holding (阿里巴巴) and ByteDance (字节跳动) privately told Nvidia they wanted to purchase, according to the same sources. That gap matters. China’s leading internet platforms are racing to train and deploy large AI models, and accelerators like the H200 and MI325 are prized for compute-hungry workloads. With a per-customer cap, those firms could receive only “hundreds of thousands” of units collectively at most—well below reported appetite.

Geopolitics keeps reshaping the chip playbook

Since 2022, successive rounds of US export controls have curbed China’s access to advanced semiconductors, forcing Nvidia to create downgraded, China-specific parts and pushing Chinese buyers to stockpile or seek domestic alternatives. The Bureau of Industry and Security (BIS), which oversees export licensing, declined to comment, as did AMD. Nvidia, Alibaba, and ByteDance did not respond to requests for comment. The broader context is clear: Washington aims to slow Beijing’s progress in frontier AI, while trying to avoid a total market cutoff. Can a quota square that circle?

What to watch next

Details on enforcement, scope, and timelines remain unclear. Will the cap apply retroactively? How will mixed AMD-Nvidia deployments be tallied? Any finalized rule could reshape procurement strategies across China’s cloud and internet sectors, while intensifying investment in domestic accelerators from players like Huawei and other fabless startups. For US chipmakers, the policy would preserve some China revenue—just not as much as their biggest customers want.
