SK hynix links US NAND fab plans to China equipment export approvals
The South Korean chipmaker conditions its US manufacturing commitment on Washington allowing new tools for its Dalian facility.
Key points
- SK hynix proposes building a 3D NAND fab in the US in exchange for export licenses for its Dalian, China facility.
- The Dalian plant is the sole producer of 192-layer floating gate 3D NAND for Solidigm's data center SSDs.
- The US Commerce Department granted limited equipment authorization for 2026 but has not issued approvals for 2027.
SK hynix is reportedly conditioning its commitment to build a new 3D NAND flash memory fabrication plant in the United States on the US government authorizing additional semiconductor manufacturing equipment exports to its facility in Dalian, China. According to Reuters, this calculated move ties the company’s domestic investment directly to regulatory permissions for its Chinese operations.
The proposal addresses a specific gap in the Trump administration’s efforts to bring semiconductor manufacturing back to American soil. Solidigm, SK hynix’s subsidiary, had previously signaled interest in constructing a US-based 3D NAND fab, a development that surprised industry observers since no company has manufactured NAND flash memory in the US for years. The current negotiation framework suggests the parent company is leveraging this potential investment to secure operational continuity abroad.
Context and Background
The Dalian facility holds a unique position in the global supply chain as the world’s only site producing 192-layer floating gate 3D NAND. This specific memory technology powers Solidigm’s solid-state drives designed for AI, enterprise, and hyperscale data centers. The manufacturing process at this site relies heavily on equipment from major American suppliers, including Applied Materials, KLA, and Lam Research.
Exports of these critical tools to China require explicit licensing from the US government. US authorities have historically authorized shipments of certain tools to semiconductor facilities in the People’s Republic operated by multinational companies like Samsung or SK hynix. However, these authorizations are typically limited to keeping existing fabs running. The government opposes expanding capacity or introducing new manufacturing technologies to Chinese facilities, creating a regulatory bottleneck for SK hynix.
Who Is Affected
Solidigm has formally requested US export licenses for additional tools to install in the unused portions of its Dalian Mod B facility, which was completed in 2023. While the US Commerce Department granted SK hynix a limited authorization for equipment deliveries to Dalian for 2026 last December, it has not issued a similar export authorization for 2027. The lack of a 2027 approval creates uncertainty for the company’s long-term production planning.
This standoff affects the broader US strategy to reduce reliance on foreign semiconductor manufacturing. By linking the US fab construction to Chinese export approvals, SK hynix is effectively testing the boundaries of US export control policy. The outcome will influence whether Solidigm can maintain its exclusive production of high-layer-count NAND in China while simultaneously establishing a domestic manufacturing footprint.
What should you do?
Security and technology professionals should monitor developments in semiconductor supply chain regulations, as shifts in export controls can impact hardware availability. Organizations relying on Solidigm SSDs for AI and enterprise workloads should assess their inventory levels and diversify suppliers where possible. IT leaders should track official statements from the US Commerce Department regarding license approvals for 2027.
What to do and how to stay safe: SK hynix
- Review current data center storage contracts to identify dependencies on single-source NAND suppliers.
- Monitor US Commerce Department announcements for updates on semiconductor export license policies.
- Assess the potential impact of supply chain disruptions on AI and enterprise workload performance.
- Engage with procurement teams to develop contingency plans for hardware shortages.
