China Disrupts Global AI Chip Production With Micro-Drill Shortage

New export restrictions introduced by China on critical metals have led to severe disruptions in the supply of micro-drills. These tiny precision tools are vital components in the manufacturing chain of chips designed for artificial intelligence systems.

• China's tungsten export restrictions have triggered multiple price hikes for micro-drills worldwide.
• Ammonium paratungstate benchmark prices surged from 212,750 yuan to over 530,000 yuan per ton.
• Foreign manufacturers are increasingly forced to rely on Chinese supply chains to bypass restrictions.

The Critical Role of Tungsten in Semiconductors

Micro-drills resemble tiny needles and are primarily made of tungsten carbide. They are used to create microscopic holes in printed circuit boards and chip substrates, ensuring proper connections between various electronic layers.

As circuit boards become increasingly complex with more layers and harder materials, the demand for high-precision micro-drills grows. Leading suppliers in Japan, the US, Europe, and Taiwan heavily depend on China, which accounts for roughly 79 percent of global tungsten production.

Market Shifts and Surging Prices

Amid the supply crunch, Chinese companies like Guangdong Dtech Technology and Shenzhen Jinzhou Precision Technology have expanded their market share. Dtech reported a sales volume increase of nearly 180 percent and a net profit jump of over 280 percent.

Outside of China, material prices can be up to three times higher, ranging from 1.5 million to 1.8 million yuan per ton. To circumvent export controls, toolmakers are actively utilizing domestic Chinese manufacturing hubs and supply chains.

Implications for the Global Tech Industry

This situation highlights the vulnerability of global technology supply chains to geopolitical tensions. Heavy reliance on a single dominant raw material source threatens the production speed of AI accelerators and advanced electronics.

While other nations are stepping up efforts to boost alternative tungsten mining, replacing China's established dominance overnight remains nearly impossible, which could potentially impact long-term hardware costs.
