US regulations threaten Samsung’s China AI chip sales

Samsung Electronics may face challenges due to recent US regulations restricting the export of advanced AI semiconductors to China, its largest market for chip sales.

These new rules could impact Samsung’s high-bandwidth memory (HBM) chip business.

The US has expanded licensing requirements for chipmakers, including Nvidia and Intel, to sell AI processors to clients in China.

This move may also affect Chinese AI chipmakers, complicating Samsung’s regulatory navigation.

China made up 31% of Samsung’s sales in 2024, driven by Chinese companies stockpiling HBM chips ahead of US restrictions.

Although direct exports of HBM chips are restricted, Samsung’s products still reach China via third-party suppliers such as CoAsia Electronics.

🧠 Food for thought

1️⃣ China’s domestic memory manufacturers are rapidly closing the technological gap

China’s response to U.S. export controls has accelerated domestic semiconductor development, directly threatening Samsung’s market position beyond just regulatory challenges.

ChangXin Memory Technologies (CXMT) has made particularly impressive progress, achieving 80% yield in DDR5 production and targeting 90% by 2025, while also developing HBM2 capabilities critical for AI applications 1.

CXMT has already transitioned to 16nm DRAM production and plans to advance to 15nm by late 2026, steadily narrowing the technical gap with South Korean competitors 2.

The company’s market share is projected to grow from less than 2% three years ago to potentially 15% by late 2025, supported by a production capacity increase from 70,000 to 200,000 wafer starts per month between 2022 and 2024 3.

CXMT’s aggressive pricing strategy, selling DDR4 memory at a 50% discount compared to competitors like Samsung, is disrupting market dynamics and intensifying competitive pressure 4.

China’s overall semiconductor industry expansion is reflected in the rapid growth of companies like SMIC, which surpassed $2 billion in quarterly revenue for the first time in Q3 2024 4.
