The United States did not shut down Samsung’s or SK hynix’s Chinese semiconductor factories. Instead, it removed a regulatory pathway that had allowed qualifying U.S.-origin equipment shipments to reach those facilities without a separate export license for each shipment. The companies consequently moved from relatively predictable access to case-by-case approval.
That distinction mattered immediately for maintenance, replacement equipment, capacity planning, and technology upgrades. By December 2025, Reuters reported that annual U.S. licenses had been granted for equipment shipments during 2026, reducing the near-term threat. But the companies remained dependent on recurring U.S. approvals rather than the former Validated End User authorization.
The short version: uncertainty replaced predictability
On August 29, 2025, the U.S. Commerce Department’s Bureau of Industry and Security (BIS) finalized a rule removing Samsung China Semiconductor Co. Ltd. and SK hynix Semiconductor (China) Ltd. from the Validated End User (VEU) program. Intel’s former Dalian entity was also removed.
The rule was scheduled for publication in the Federal Register on September 2, 2025, and became effective 120 days later, on December 31, 2025. It did not designate Samsung or SK hynix as prohibited entities, and it did not automatically ban every U.S.-origin tool from entering China.

What changed was the authorization process. Eligible shipments that had previously moved under the VEU framework generally needed individual BIS licenses instead. Those applications could be reviewed, delayed, conditioned, or denied. In practical terms, the risk was not an immediate “lights out” order. It was a less predictable ability to repair, replace, modernize, or expand the factories.
The picture improved for 2026. Reuters, as reported by Tom’s Hardware, said the United States granted annual licenses covering chipmaking-equipment shipments to Samsung and SK hynix facilities in China throughout calendar year 2026. That reportedly prevented an immediate operational cliff, but it did not restore the former VEU arrangement or guarantee future renewals.
What VEU status actually did
VEU is best understood as a general authorization mechanism—not a blanket waiver from all export controls. Companies and facilities approved for the program could receive, reexport, or transfer qualifying items subject to the Export Administration Regulations without obtaining a separate BIS license for every qualifying transaction.

| Before VEU removal | After VEU removal |
|---|---|
| Eligible shipments could use a general authorization. | Qualifying shipments generally required individual licenses. |
| Equipment and support planning was more predictable. | Each application could involve additional review, delay, conditions, or denial. |
| Maintenance and capacity planning faced less recurring political risk. | Annual approvals and shipment-level decisions became important planning variables. |
| Washington had less frequent leverage over routine flows. | Renewals and licensing decisions created recurring leverage. |
The rule therefore changed access to a licensing pathway. It was not, by itself, a technology ban, a closure order, or an operational prohibition.
Which facilities are exposed?
| Company | Chinese facility | Primary output | Main exposure |
|---|---|---|---|
| Samsung | Xi’an | NAND flash memory | Maintenance, replacement tools, process migration, and capacity planning. |
| SK hynix | Wuxi | DRAM memory | DRAM modernization, equipment replacement, and expansion. |
| SK hynix/Solidigm | Dalian | NAND flash memory | Equipment support and the longer-term product road map. |
| Intel | Dalian entity listed in the rule | Limited direct exposure after the facility sale | Primarily a legal-listing issue rather than the central commercial impact. |
Industry coverage estimated that Xi’an produced about 40% of Samsung’s NAND output, while Wuxi produced about 40% of SK hynix’s DRAM output and Dalian about 25% of its NAND output. Those are reported estimates of each company’s output—not shares of global memory production—and are not figures established by the BIS rule or confirmed company guidance.
One September 2025 report also discussed a possible reduction in Samsung Xi’an’s monthly wafer starts from roughly 200,000 to 170,000. That was an unconfirmed industry report, not Samsung guidance.
What the rule does—and does not—stop
The action does not automatically stop current production. A factory can continue operating with equipment already installed, provided it has the necessary tools, spare parts, consumables, software, service, and regulatory authorizations.
The risk rises when a facility needs something new or unexpected:
- Shipment delay: A replacement tool, spare, or software-related item takes longer to clear.
- Maintenance constraint: Existing equipment continues running but is harder to repair or replace.
- Technology freeze: The fab keeps producing current products but cannot efficiently move to newer generations.
- Capacity freeze: The company cannot add meaningful wafer capacity in China.
Reuters reported that the Commerce Department expected to approve licenses needed to keep existing facilities operating, while not intending to approve capacity expansion or technology upgrades. That distinction reflected the administration’s reported position; it should not be confused with a rule stating that every upgrade was categorically prohibited.
Why upgrades matter more than keeping the lights on
Memory fabs are not static factories. Their competitiveness depends on continuous process improvement, yield gains, equipment qualification, and transitions to denser products.
Without timely access to equipment and support, a facility may struggle to:
Recommended Free Tools
- Install newer deposition, etch, cleaning, inspection, metrology, or process-control tools.
- Move NAND production to higher layer counts.
- Improve yield, power efficiency, or manufacturing consistency.
- Qualify new DRAM or NAND generations.
- Replace obsolete equipment with equivalent or newer systems.
- Expand wafer starts when demand increases.
This creates the possibility of technological drift: Xi’an, Wuxi, or Dalian could remain productive while gradually falling behind facilities in South Korea or elsewhere. In that scenario, the factories do not close immediately, but they become more focused on mature or older-generation products and less useful for the company’s leading technology road map.
The timeline from VEU protection to annual licensing
- October 2022: The Biden administration introduced broad restrictions on advanced semiconductor-manufacturing equipment exports to China. The VEU framework became especially important for selected foreign-operated facilities.
- 2023: The VEU framework was expanded for selected semiconductor companies and facilities, according to industry coverage.
- August 29, 2025: BIS filed the final rule removing the Samsung, SK hynix, and Intel Dalian entities from the VEU list.
- September 2, 2025: The rule was scheduled for publication in the Federal Register.
- December 31, 2025: The 120-day transition period ended.
- December 30, 2025: Reuters reported that annual licenses had been granted for Samsung and SK hynix equipment shipments during 2026.
The December licensing report changed the immediate question. The issue was no longer whether the facilities would receive any U.S.-linked equipment in 2026. It became whether future licenses would be renewed, what categories they would cover, and whether they would permit modernization or only continued operation.
Why Samsung and SK hynix are more exposed than other chipmakers
The impact is not uniform across foreign-owned semiconductor operations in China.
- Samsung and SK hynix: Both have substantial memory-manufacturing assets in China, making them sensitive to equipment, maintenance, and product-transition restrictions.
- Micron: Its Chinese presence includes assembly and test operations rather than an equivalently exposed advanced memory-fabrication footprint.
- TSMC: Its Nanjing operation has a different profile and, according to industry coverage, retained a different VEU position. It operates mature process technology, so it should not be treated as directly equivalent to Samsung’s or SK hynix’s memory fabs.
- Intel: The Dalian entity’s listing mattered legally, but Intel’s sale of the facility to SK hynix reduced its direct commercial exposure.
Equipment makers also face an uneven trade-off. Applied Materials, Lam Research, and KLA may lose sales or support opportunities in China, while Chinese equipment vendors gain an incentive to qualify tools for process steps currently dependent on foreign suppliers. Reuters reported that major U.S. equipment companies’ shares fell after the announcement.
Who could gain—and who could lose?
Micron could benefit if Samsung and SK hynix are unable to expand or modernize their China-based output. But the result depends on memory demand, inventory, pricing, product mix, and available capacity elsewhere; a guaranteed benefit cannot be assumed.
Chinese memory companies such as CXMT and YMTC could gain market space if foreign-tool access becomes less reliable. Chinese equipment makers could also benefit from an expanded opportunity to qualify domestic alternatives. Those outcomes are plausible competitive effects, not certain results.
Global memory buyers could face tighter supply if equipment delays materially reduce output or slow product transitions. A worldwide shortage is not inevitable: inventory, demand, production allocation, and alternative capacity will determine the market effect.
South Korea’s companies remain exposed to U.S. policy. Seoul must balance access to the U.S. semiconductor-equipment ecosystem with the protection of Samsung and SK hynix’s sunk investment in China, continued access to Chinese customers, and global supply-chain stability. South Korea’s industry ministry said stable operation of Korean semiconductor companies in China was important and that it would continue discussions with Washington.
The strategic choices facing Samsung and SK hynix
1. Keep existing Chinese operations running
This preserves local capacity, customer access, trained labor, and the value of installed equipment. The drawback is continuing exposure to annual U.S. licensing decisions and a potential decline in competitiveness if upgrades are restricted.

2. Put advanced investment in South Korea or elsewhere
This offers more predictable access to advanced tools and may simplify technology-road-map planning. It also requires substantial capital, new construction, lengthy qualification, and potentially years to replace China-based capacity.
3. Use Chinese equipment selectively
Domestic tools could reduce dependence on U.S. licensing for selected process steps. However, substitution can create qualification, yield, compatibility, performance, and regulatory risks. Non-U.S. equipment is not automatically outside all export controls.
A Reuters-sourced report in August 2026 said Samsung and SK hynix were evaluating Chinese equipment from AMEC as a hedge against tighter controls. SK hynix denied testing or considering that equipment, so the claim should be treated as disputed rather than an established company strategy.

This would reduce long-term exposure to licensing uncertainty and simplify technology planning. It could also destroy asset value, reduce output, disrupt customers, and make it difficult to replace capacity quickly. Neither company’s complete withdrawal from China should be inferred from the VEU decision.
What investors and supply-chain watchers should monitor
- Whether licenses for 2027 and later years are renewed.
- Whether approvals cover only maintenance and existing production or also modernization.
- Any new BIS rules affecting foreign-owned semiconductor fabs in China.
- Samsung and SK hynix capital-expenditure allocations by geography and product generation.
- Equipment qualification at Xi’an, Wuxi, and Dalian.
- Changes in output, wafer starts, product mix, or technology migration at the three facilities.
- Statements from Seoul, Beijing, Washington, and major semiconductor-equipment vendors.
The most useful distinction is between authorization to keep operating and authorization to remain technologically competitive. The reported 2026 annual licenses addressed the first issue for the near term. They did not eliminate the second.
