China 50% domestic chip rule – the quiet mandate that’s sending ripples through the global tech world, and as a semiconductor enthusiast who’s tracked the U.S.-China chip wars for years, I’m fascinated by this latest escalation. Revealed on December 30, 2025, via Reuters sources, China is now requiring chipmakers to source at least 50% of equipment from domestic suppliers when expanding or building new fabrication plants (fabs). This unpublished rule, enforced through state approvals and procurement tenders, aims to fast-track self-reliance amid U.S. export curbs on advanced tools. For companies like Naura Technology and AMEC, it’s rocket fuel – revenues are soaring as fabs pivot local. But for foreign giants like ASML and Lam Research? Market share erosion in the world’s largest chip consumer. The China 50% domestic chip rule isn’t just policy; it’s a strategic pivot that could redefine AI hardware supply chains by 2030.
In this deep dive, we’ll unpack the rule’s origins, winners and losers, and my speculations on its long-term effects. If you’re as intrigued by the geopolitics of silicon as I am, let’s chip away at why the China 50% domestic chip rule matters big time.
Origins and Details of the China 50% Domestic Chip Rule
The China 50% domestic chip rule emerged quietly in recent months, with authorities informing chipmakers during approval processes that new capacity expansions must demonstrate at least 50% domestic equipment via tenders. No public document exists, but sources confirm it’s non-negotiable for most projects – though relaxed for cutting-edge nodes where local tech lags.
Driven by U.S. restrictions since 2023 banning advanced AI chips and tools, the rule accelerates “Made in China 2025” goals. Authorities reportedly prefer ratios “much higher than 50%,” eyeing eventual 100% domestic reliance.
This builds on the Big Fund (Phase 3: ¥344B in 2024) and surges in local orders – 421 lithography procurements worth ¥850M in 2025 alone.

Winners: Domestic Champions Thriving Under China 50% Domestic Chip Rule
The China 50% domestic chip rule is a boon for local equipment makers.
- Naura Technology: Revenue up 30% H1 2025 to ¥16B; record 779 patents; leading in etching/cleaning (50% self-sufficiency).
- AMEC: 44% revenue jump to Â¥5B; advancing in advanced etching for SMIC’s 7nm lines.
Analysts predict domestic firms dominating legacy tools, squeezing Japanese/Korean suppliers.
I’m excited – this forced adoption accelerates innovation; Naura’s tools now rival Lam Research in some areas.
Losers and Global Impact of the China 50% Domestic Chip Rule
Foreign suppliers face pain:
- ASML, Lam, Tokyo Electron: Reduced China market access, even for non-restricted tools.
- Korean firms (Zeus, GST): Sales drops as fabs comply.
Globally, it fragments supply chains – hyperscalers diversify, while China builds parallel ecosystem.
Table of impacted segments:
This China 50% domestic chip rule could delay expansions short-term but strengthen long-term resilience.
Broader Implications for AI and Tech
The China 50% domestic chip rule fuels AI sovereignty – more local fabs mean cheaper, unrestricted compute for models rivaling Western ones.
Speculation: By 2030, China captures 60% legacy market, freeing capacity for advanced nodes despite curbs.
For AI devs, dual ecosystems emerge – Western restricted, Chinese open but localized.

Key Takeaways
- Rule Essentials: ≥50% domestic equipment for new/expanded fabs; enforced via approvals.
- Domestic Boost: Naura/AMEC revenues surge; 50% self-sufficiency in key tools.
- Foreign Squeeze: Reduced market for US/Japan/Korea suppliers.
- Long-Term Goal: Aim for 100% domestic; accelerates post-US curbs.
- Industry Shift: Potential short delays, long-term China independence.
Final Thoughts: My View on the China 50% Domestic Chip Rule’s Legacy
The China 50% domestic chip rule has me reflecting on tech nationalism – it’s a pragmatic response to curbs, supercharging local innovation while fragmenting globals. As an AI follower, I’m curious if it births uniquely efficient tools optimized for China’s needs. Opinion: Short-term pain for foreigners, but long-term, diversified chains make the industry resilient. Prediction: This rule cements China as legacy king, forcing West to innovate harder.
