Allied chip export controls were designed to slow China's semiconductor localisation. The latest data suggests they are accelerating the parts that matter most. Equipment self-reliance reached 35% in early 2026, surpassing Beijing's own 30% target ahead of schedule, while a new mandate now requires at least 50% domestic equipment in new fabs. For global manufacturing supply chains, this means equipment markets are bifurcating along geopolitical lines, creating dual-qualification burdens and procurement disruptions for manufacturers dependent on mature-node chips from Chinese fabs.
Executive Summary
- Equipment self-reliance accelerates: China hit 35% semiconductor equipment self-sufficiency, exceeding its own target, with a 50% domestic equipment mandate now in force for new fabs.
- Design-out risk is commercial, not theoretical: Chinese manufacturers are actively replacing Western equipment suppliers in deposition, etching, process control, and testing.
- Supply chain bifurcation: Global manufacturers face dual-qualification burdens and procurement timeline disruptions as chip supply chains split along geopolitical lines.
Where the Numbers Moved Fastest
Naura, China's leading domestic semiconductor equipment maker, is now testing its etching tools on SMIC's 7nm production line after successful deployment at 14nm. The company's revenue jumped 30% in the first half of 2025 to 16 billion yuan. AMEC, another domestic champion, reported 44% revenue growth to 5 billion yuan over the same period. These are not pilot-stage numbers.
Patent filings tell the acceleration story differently. Naura filed 779 patents in 2025, more than double its output in 2020 and 2021. State-affiliated entities placed 421 orders for domestic lithography machines and components in 2025, worth approximately 850 million yuan. Behind the macro policy sits real procurement volume.
Beijing's Big Fund launched its third phase in 2024 with 344 billion yuan (US$49 billion) in capital. China's projected fab tool spending will reach US$47 billion in 2026. The money is flowing toward a specific outcome: indigenous capability across the equipment stack, from deposition to testing.
How Semiconductor Localization Converts to Design-Out Risk
CSIS has documented the design-out phenomenon across at least four equipment categories: deposition, etching, process control, and testing. Chinese fabs are not merely supplementing Western tools with domestic alternatives. They are actively replacing them, driven by government "white lists" of approved domestic suppliers and the commercial logic of de-risking supply chains that could be cut at any time.
Chinese officials have signalled that 50% domestic equipment is a floor, not a ceiling. The long-term target is 100%.
For Western equipment makers, the revenue impact is already visible. NVIDIA's market share in China has declined from approximately 90% to around 50%. Applied Materials, Lam Research, and Tokyo Electron face a market that is not shrinking but redirecting. China's total equipment spending is rising while the share flowing to foreign suppliers contracts quarter by quarter.
The 50% mandate carries an embedded ratchet. Sources with direct knowledge of the approval process report that authorities prefer the figure to be "much higher." Applications failing the threshold are typically rejected, though flexibility is granted for advanced production lines where domestic tools are not yet viable.
What This Means for Manufacturing Leadership
Technology leaders sourcing semiconductor manufacturing equipment face a bifurcating market. Equipment qualified for Chinese fabs will increasingly need to meet domestic content requirements that exclude Western components. Equipment qualified for non-Chinese fabs will need to demonstrate compliance with allied export controls. Dual qualification is becoming structurally expensive.
Within the next 12 months, the immediate decision is procurement, not geopolitics. CTOs should request a supplier-tier mapping from procurement identifying which chip components are fabricated in Chinese fabs currently transitioning to domestic equipment, particularly in deposition and etching where design-out is most advanced. A fab retooling its etching line with domestic tools may produce subtly different yield characteristics at mature nodes (28nm and above). Quality assurance teams should flag any Tier 1 semiconductor suppliers that have disclosed equipment line changes in the past six months and schedule incoming inspection recalibration for those components.
The broader strategic question: does Western semiconductor equipment leadership survive a market where its largest customer is legally required to stop buying? The controls were designed to maintain a technology gap. The data suggests they are maintaining that gap at advanced nodes while surrendering the mature-node equipment market entirely. For manufacturers whose products depend on chips made at those mature nodes, the supply chain has already begun to split.
