SK hynix is moving to resume equipment investment at its second NAND fab in Dalian, China. IB Tomato reported on July 8, 2026 that the company plans to begin bringing in production equipment in the second half of the year and gradually build out facilities through the first half of 2027. Separate Korean media reports indicate the investment targets a new V8 line with a capacity of 30,000 to 50,000 wafers per month. However, while SK hynix acknowledged that the likelihood of a restart has increased, it responded that "a specific schedule has not yet been finalized."
The Dalian restart carries two implications. Using the existing building would allow supply to increase faster than M17, the new NAND fab in Cheongju, Korea, which is targeting operation in the first half of 2029. On the other hand, the annual export license the U.S. approved in 2026 covers only pre-approved equipment, and the specific items have not been disclosed. For the figure of 50,000 wafers per month to translate into actual supply, it must clear not only the investment decision and equipment delivery but also the scope of U.S. approval.
Phased rollout through H1 2027, but schedule remains unconfirmed
According to IB Tomato, SK hynix plans to bring production equipment into Dalian Fab 2 starting in the second half of 2026, building out the line in stages through the first half of 2027. Korean partner companies have reportedly begun moving idle NAND equipment to Dalian, and advance purchase orders have reportedly already reached overseas equipment makers. Since the plan does not involve constructing a new building before installing equipment, ramp-up can proceed faster than at a new fab, which requires securing land and basic infrastructure first.
The reported scale of the plan is 30,000 to 50,000 wafers per month. This figure refers not to the number of finished SSD units or shippable storage capacity, but to a rough estimate of the number of wafers that can be processed per month. Actual bit supply will vary depending on the number of NAND layers adopted, the number of good dies obtainable per wafer, and the mix of TLC and QLC. Yield also affects the numbers. A maximum of 50,000 wafers will not simply be added to the market as-is.
At the existing Dalian Fab 1, reports indicate that conversion to 192-layer NAND and replacement of aging equipment are underway. If Fab 2's V8 line comes online, Dalian would be simultaneously improving efficiency at existing lines while adding new wafer capacity. However, what the company has acknowledged extends only to an increased likelihood of a restart. The month equipment delivery begins, the timing of mass production, and the investment amount have not been decided.
A candidate to bridge the gap until M17 comes online in 2029
On July 2, SK hynix announced a 80 trillion won investment in the new NAND fab M17 in Cheongju. Construction is set to begin in 2027, with an operational target of the first half of 2029. Even in Cheongju, where land, power, and water supply are ready, the new front-end fab will not immediately close the current supply shortage.
Dalian Fab 2 is a candidate to bridge this time gap. Although construction of the facility began in May 2022, equipment investment was effectively halted due to the combination of the NAND downturn and export restrictions targeting China. If the completed space and the existing site's personnel and infrastructure can be utilized, it becomes possible to proceed with wafer input ahead of M17. This is why it is regarded as the site among SK hynix's NAND production locations that can increase capacity most quickly.
Demand-side conditions have also changed. In the first quarter of 2026, SK hynix explained that AI investment is expanding from HBM and server DRAM into enterprise SSDs, and that customer demand for NAND is now exceeding supply capacity. In the NAND market that quarter, the company held an 18.5% revenue share according to IDC data, ranking second globally. If a formal investment decision and equipment approval align, and Dalian can be brought online while the supply shortage persists, shipped bits could increase and be channeled into Solidigm's high-capacity SSD business.
However, the window in which Dalian can serve as a bridging candidate is limited. If mass production at Dalian is delayed, the time gap with M17 narrows, shortening the period during which equipment installed earlier can be recouped. The reported schedule—delivery beginning in the second half of 2026 and facility construction through the first half of 2027—is also a condition that will determine investment profitability.
Two product foundations: 192-layer and V8
Dalian's value is not determined by wafer count alone. The NAND business SK hynix acquired from Intel now feeds into what is today Solidigm. Solidigm's high-capacity QLC SSD, the "D5-P5336," uses 192-layer NAND and packs up to 122.88TB into a single drive. In read-intensive AI data infrastructure and data lakes, the ability to increase recording density and thereby reduce SSD count, rack space, and power consumption is a competitive advantage.
Meanwhile, SK hynix itself has progressed its process technology from 176 layers to 238 layers and 321 layers. Mass production of 238-layer 4D NAND began in 2023, and according to the company's announcement, it improved production efficiency by 34% compared to 176-layer NAND while raising data transfer speed to 2.4Gbps. In 2026, the company also began supplying the "PQC21" client SSD using 321-layer QLC. The current product lineup includes both Solidigm's strong 192-layer QLC high-capacity eSSDs and SK hynix's own higher-layer NAND.
It has not been disclosed which products the reported "V8" at Dalian Fab 2 will be allocated to. The economic effect of the expansion will vary depending on whether the 238-layer process is moved to Dalian, what ratio of TLC to QLC will be produced, and whether client SSDs or eSSDs are prioritized. The figure of 30,000 to 50,000 wafers per month is merely an entry-level number; what determines profitability is the number of good bits and the per-product unit price.
Annual licenses make delivery more predictable, but expansion approval is a separate question
The biggest constraint on the Dalian plan is U.S. export controls on semiconductors to China. In August 2025, the U.S. Department of Commerce's Bureau of Industry and Security (BIS) removed Intel's Dalian site, Samsung's China site, and SK hynix's China site from the Validated End User (VEU) program. Under VEU, companies could bring in covered items without filing individual applications, but after its removal, export licenses became required.
At the same time, BIS indicated its intention to approve licenses allowing former VEU-designated companies to operate their existing fabs in China. However, it also explicitly stated a policy of not granting approval for applications aimed at expanding production capacity or upgrading technology at China-based fabs. Bringing in replacement parts for maintenance and building a new line at an idle Fab 2 are not necessarily treated the same way under this policy.
Subsequently, BIS granted SK hynix an annual license for 2026. According to the company's most recent filing with the U.S. Securities and Exchange Commission, this allows shipment of pre-approved U.S.-origin equipment to its China sites throughout 2026, eliminating the burden of case-by-case applications. However, neither the list of approved equipment nor whether the V8 line at Dalian Fab 2 is included has been disclosed. The annual license has restored predictability to the delivery plan, but it is not proof that expansion itself has been approved.
There is also a time boundary to consider. Under the plan reported by IB Tomato, facility construction continues through the first half of 2027. Even if equipment can be brought in within 2026 under this year's approval, any additional equipment or parts needed the following year will depend on approvals granted for 2027. Therefore, assessing the feasibility of the Dalian plan requires watching not only the initial delivery in the second half of 2026, but also the scope of the 2027 annual license renewal.
Three conditions to confirm before the 50,000-wafer figure means anything
If Dalian Fab 2 comes online, SK hynix would be able to increase NAND supply without waiting for M17 to become operational, making it easier to link the production assets acquired from Intel with Solidigm's eSSD business. If it launches at a time when demand for high-capacity QLC SSDs for AI data centers exceeds supply capacity, the previously idle building could be converted into increased shipments.
The conditions to watch narrow down to three. First, whether SK hynix formally finalizes the investment amount and equipment delivery schedule. Second, whether the 2026 and 2027 U.S. licenses cover the equipment needed for the new line. Third, what number of layers and cell type the V8 line adopts, and how it allocates the ratio between TLC and QLC, and between client and enterprise applications.
The first checkpoint will come with equipment delivery in the second half of 2026. If the type, origin, and intended use of the new production equipment can be confirmed—along with confirmation that these fall within the scope of the annual license—it will become possible to judge how far U.S. approval actually permits Dalian's capacity expansion. If wafer input and mass production timing are further disclosed, it will also become clearer whether the 30,000-to-50,000-wafer-per-month figure will translate into actual supply in 2027.
