SK Hynix reportedly conditions a new US NAND fab on approval to move more US-made gear to its Dalian plant
Reuters, citing two sources, says SK Hynix unit Solidigm asked Washington for more US tools at idle Mod B in Dalian, tied to a new US NAND fab. SK Hynix denies.
Reuters reported on October 15 that Solidigm — SK Hynix’s US NAND subsidiary — has asked Washington for approval to ship more American chipmaking equipment into the unused Mod B space at its Dalian, China plant, and that it has tied that license to whether it proceeds with a new NAND fab in the United States. The request was made on Wednesday, October 14, according to two people familiar with the matter cited in the report. SK Hynix then told Reuters and TechCrunch that it has no plan to expand capacity at Mod B, and that installation is proceeding in consultation with, and under authorization from, the US government.
Key points
- The ask: Solidigm filed the request on October 14 to install more US-made tools in Dalian’s idle Mod B space; the account comes from two anonymous sources cited by Reuters.
- The dispute: SK Hynix frames the same site as having “no expansion plan,” with installation already authorized — the same equipment, opposite conclusions.
- The market read: CoinCentral reports SK Hynix (000660) closed down about 11% at 1,262,000 won on October 15, with Lam Research, Applied Materials and KLA down roughly 5%, 4% and 3%.
How the export rules tightened
The request only makes sense against the specific text of US equipment controls on China. Washington imposed broad export limits on advanced chips and chipmaking tools in October 2022 and tightened them in 2023, as TechCrunch’s recap runs. What changed SK Hynix’s position was September 2025, when the Commerce Department revoked the special authorizations that had covered Samsung and SK Hynix’s China fabs for US-origin tools, moving to case-by-case approvals instead.
TrendForce has the fullest timeline. The department said it would keep supplying equipment needed to sustain current operations, but would not back exports for capacity expansion or technology upgrades. In December 2025, both companies received yearly approvals for 2026 shipments to their Chinese fabs. Per Reuters, SK Hynix’s Dalian authorization limits equipment quantities, and the 2027 incremental approval has not yet been issued. Solidigm’s request covers exactly the category the policy names.
The push from the other side comes from Commerce Secretary Howard Lutnick, who said in July that he “wanted Samsung and SK Hynix to build chip plants in the country,” as TechCrunch notes. One department is capping incremental tools at Dalian while urging Korean memory makers to start output in America.
The facts
Little of the request itself is on the record; the checkable details sit in the fab’s status and the dates. Mod B is a fabrication space at the Dalian campus, completed in 2023, whose outfitting was left unfinished because of the memory market downturn — TechCrunch, TrendForce and Chosunbiz describe it the same way. The Dalian plant runs tools from Lam Research, Applied Materials and KLA, the three suppliers TrendForce lists.

| Mod B completion | 2023; outfitting left unfinished in the downturn | TechCrunch / TrendForce / Chosunbiz |
| Dalian tool suppliers | Lam Research, Applied Materials, KLA | TrendForce |
| Q4 NAND pricing | Expected up 15%–20% | TrendForce, via TechCrunch |
| Cumulative NAND rise | About sevenfold since mid-2023 | TechInsights, via Chosunbiz |
| SK Hynix shares | Down about 11% on Oct 15, closing at 1,262,000 won (-157,000) | CoinCentral |
| Tool makers | Lam about -5%, Applied Materials about -4%, KLA about -3% on Oct 15 | CoinCentral |
NAND prices come with two different yardsticks from two different firms, and they should not be merged: TrendForce expects contract prices up 15%–20% in the fourth quarter, while TechInsights counts roughly sevenfold growth since mid-2023. One is forward-looking, one is a retrospective tally, and together they explain why idle capacity suddenly carries value. Our October 1 entry on the memory crunch running to 2028 sits on the same line: Micron’s CEO said 2027 output is already 75% booked.
One caveat on how this entry was built: two attempts to fetch the Reuters original returned HTTP 401 Forbidden. The specific wording was cross-checked through a ground.news summary and the reports of TechCrunch, TrendForce, Chosunbiz and Sina Finance, so anything sourced to the Reuters exclusive is written here as reported, not as verified fact.
Two accounts of the same building
The Reuters version turns on the swap: sources said Solidigm tied the Dalian license to a new American NAND fab, and that added output at Dalian could pay for the US plant and serve as a bridge to more production at home. Chosunbiz’s headline writes that logic out as causation — “SK hynix links Dalian equipment approval to US NAND plant investment” — with a subhead noting the US talks “add pressure on Solidigm’s stateside NAND plans amid tight export curbs.”
SK Hynix’s rebuttal is specific on three counts: Mod B was completed in 2023, there is no capacity expansion plan, and installation is proceeding in close consultation with and under authorization from the US government. Its line to Reuters was “We are not pursuing a production capacity expansion,” repeated to TechCrunch. Solidigm itself declined to comment, per TrendForce.
The two accounts are not mutually exclusive. Filling equipment into a building finished in 2023 can be called completing original construction in a company filing, and capacity expansion in a regulator’s ledger. The difference shows up in the monthly wafer number after the tools are in. That is the reservation this entry holds about the denial: it contests the label, not the installation.
A second set of figures could not be matched against the Reuters account. A Tencent News post relaying a Chaoneng report says the second Dalian fab restarted expansion in the second half of 2026, is planned to produce 238-layer NAND at 30,000 to 50,000 wafers per month, and that the Wuxi DRAM fab is moving from 1znm to 1αnm. That report cites TrendForce and its own sources, a separate chain from Reuters’ anonymous sourcing, so those numbers are carried here as a third-party caliber only.
No primary official document has surfaced for this event. SK hynix’s FACT newsroom page still shows its most recent item as an October 1 note on Solidigm, with nothing on October 15 or 16 about Dalian, Mod B or an export license, and the Commerce Department has posted no corresponding announcement. The only company position on record is the denial given to reporters.
How the tape priced it
CoinCentral’s October 15 read: SK Hynix closed about 11% lower at 1,262,000 won, shedding 157,000 won in a day, while the US-listed SKHY ADR fell about 6% and sits roughly 12% below its July 2026 listing. The three tool makers moved with it, down about 5%, 4% and 3%. The report frames this as part of a broad technology sell-off rather than a company-specific miss.
The tool makers belong in the frame because they are the actual suppliers for the Dalian installation; whether a license is granted decides whether the order executes. That is the other end of the same policy line as our October 2 entry on the US arresting a chip-smuggling CEO: one end is prison for moving chips in, the other is a paperwork gate for moving equipment in.
Discount this set of numbers. It comes from a single outlet, and CoinCentral also lists 11 analysts rating SKHY a “Strong Buy” with a $254.70 average target — about 73% upside on its own framing — so the sell side and the tape disagree. Read it as a sentiment datapoint, not a valuation.
Our take
For anyone buying memory or pricing a product around it, the immediate use is to calibrate supply expectations. If Mod B really restarts on the third-party caliber, incremental 238-layer NAND would ease pressure on SSDs and data center storage; if the “no expansion” framing holds, the tightness runs at TrendForce’s projected 15%–20% Q4 climb. Those two scenarios move BOM cost in opposite directions, which makes this worth tracking rather than concluding.
For anyone watching semiconductor policy, the granularity is the story. Earlier arguments centered on whole systems, whole cards, EDA and process nodes; this one lands on whether an existing fab’s idle space can take new tools. That kind of license has far more judgment room than a node number, which also makes it easier to trade — tying a license to a fab commitment is a posture Korean memory makers had not put on the table publicly before.
Three reservations stand. Reuters’ text was not read directly, so the credibility of two anonymous sources cannot be independently weighed. The arbiter between the company’s denial and the press framing is the Commerce Department, which has published nothing on this case. And the causal link to Solidigm’s 2027 IPO is mostly source speculation: Bloomberg reported on October 7 that it is preparing a US listing to raise about $10 billion at a valuation up to $100 billion, but whether Dalian output, the American fab and the IPO serve each other rests on “a source,” with no company or regulator document behind it.
What to watch
Four dated checkpoints are queued. First, whether the 2027 annual approval for China-bound equipment is issued, and at what quantity — TrendForce states plainly that the incremental approval has not been granted. Second, whether the Commerce Department publishes a conclusion on this individual case. Third, whether Solidigm’s US NAND site moves from upstate New York as the leading candidate, which Reuters reported last month, to a specific parcel. Fourth, the IPO clock: if a 2027 listing goes ahead on Bloomberg’s reporting, the prospectus will be the first public document tying Dalian capacity to the cost of the American build — harder material than an anonymous source.
Until then, every number in this entry stays in reported form.
