U.S. Export Waiver Revocations: Samsung and SK hynix Face a New Reality
Washington’s U.S. Export Waiver Revocations for Intel, Samsung, and SK hynix end a period of relative predictability for moving advanced wafer-fab tools into China. The change starts a 120‑day wind‑down; after that, affected companies will need licenses—reviewed case by case, often taking three to six months—to buy U.S. equipment for their China fabs. For Samsung and SK hynix, that timeline collides with high-stakes memory transitions and capacity planning.
What the U.S. Export Waiver Revocations actually change
- Background: The Validated End-User (VEU) program was expanded in 2023 to let select firms ship certain U.S. fab tools to vetted China sites without licenses, provided they weren’t tied to military or intelligence end uses.
- What’s ending: Those blanket waivers are being pulled. Shipments that once flowed with VEU approvals will now require individual licenses.
- Timing: A 120‑day grace period precedes full enforcement, giving companies a short window to adjust orders, inventories, and tool installations.
- Practical impact: Because the U.S. Export Waiver Revocations shift shipments into license-by-license reviews, critical upgrades can face delays, rescheduling, or re-scoping—especially for leading-edge or sensitive process steps.
Who is most exposed to the U.S. Export Waiver Revocations?
Samsung
- Xi’an is central to Samsung’s NAND strategy, producing a large share—often cited near 40%—of its global output.
- Upgrades at risk: Samsung is mid-transition from 128‑layer NAND to 236‑layer and toward 286‑layer devices. Slower access to advanced etch, deposition, and metrology tools could drag timelines, affecting bit growth and die-cost roadmaps.
- Capacity moves: Reports suggest Samsung has weighed trimming wafer starts at Xi’an by about 10% (roughly from 200k to 170k wafers per month) to keep supply-demand balanced if upgrades slip.

SK hynix
- DRAM in Wuxi accounts for a substantial portion of SK hynix’s total DRAM output (commonly estimated around 40%). Any delay in advanced DRAM equipment can ripple through yields, power efficiency, and node migrations.
- NAND in Dalian (acquired with Intel’s NAND business, now Solidigm-branded for certain products) produces a significant share of SK hynix NAND—about a quarter by some estimates—making access to 3D NAND tooling just as strategic.
- 2024 capex in China reportedly included tens of millions of dollars for Wuxi (DRAM), Dalian (NAND), and Chongqing (packaging). Licensing hurdles could re-time those investments.
Who is less affected—and why
- Intel: Minimal exposure; it sold the Dalian NAND fab to SK hynix in 2020. Its Chengdu site focuses on assembly and test, which generally rely on less sensitive equipment.
- Micron: Similar story in Xi’an—assembly/test, not leading-edge wafer fabrication.
- TSMC: Its China operations lean to mature nodes (e.g., 28 nm and 16 nm–class in Nanjing under longstanding approvals; 130 nm and 180 nm in Shanghai). That mix and prior authorizations leave TSMC comparatively insulated.
What this means for supply, pricing, and China’s tech stack
- Memory supply and pricing: If Samsung and SK hynix slow layer or node transitions in China, bit supply growth could ease, supporting firmer DRAM/NAND pricing in the near to mid term. Conversely, aggressive ramps in Korea or elsewhere could offset some of that pressure.
- Shift to mature nodes: Fabs in China may tilt more toward legacy processes if advanced upgrades get stuck in licensing queues. Expect sustained demand for tools and materials serving mature-node capacity.
- China’s domestic push: Local equipment makers and memory producers—such as YMTC (3D NAND) and CXMT (DRAM)—could gain share and experience. CXMT is widely reported to be moving from DDR4/LPDDR4 toward DDR5/LPDDR5, and policy support could accelerate that evolution.
For U.S. equipment makers, the U.S. Export Waiver Revocations could dampen near-term sales into China even as the global tool cycle recovers. Applied Materials, KLA, and Lam Research have all derived substantial revenue from China in recent years; prolonged licensing friction risks shifting some demand toward domestic Chinese vendors over time.
Strategy options for Samsung and SK hynix:
- Front‑load applications: File early and often for the most time‑critical tools; sequence installations so bottleneck steps keep moving.
- Rebalance capacity: Pull forward ramps in Korea or other regions to protect product roadmaps while keeping China lines running on mature or mid‑transition layers.
- Process partitioning: Where feasible, split sensitive steps (e.g., certain patterning or metrology operations) to non-China fabs while maintaining assembly, test, or less sensitive wafer steps in China.
- Negotiate tailored licenses: Work with Seoul and Washington on predictable, renewable authorizations that define allowed configurations, throughput caps, or China-specific SKUs. Media reports have suggested creative licensing arrangements for other U.S. chip suppliers; memory makers could pursue similarly structured paths.
- Engage customers: Lock in supply commitments and qualification schedules to reduce surprises if tool deliveries slip.
Implications for policy and geopolitics
- Seoul–Washington talks: Expect export licensing to surface alongside tariff and supply-chain discussions. South Korea will seek clarity and timelines to stabilize its flagship industry.
- Contingency planning: Firms will scenario-plan around license lead times, approval probabilities, and alternative tool chains—especially for modules where credible non‑U.S. options exist.
Investor and partner watchlist
- License throughput: Approval rates and timelines over the next two quarters.
- Xi’an/Wuxi/Dalian utilization: Any sustained cuts in wafer starts signal delayed transitions.
- DRAM/NAND spot prices: Pricing resilience would reflect constrained bit growth.
- Tool orders/backlog: Mix shift from China to other regions, and the pace of domestic Chinese tool adoption.
As the 120‑day wind‑down proceeds, the U.S. Export Waiver Revocations usher in a period of managed uncertainty. Samsung and SK hynix don’t have the option to simply walk away from China—it’s both a manufacturing base and a vital market. The likely near-term playbook: keep China fabs running, prioritize licenses for critical upgrades, accelerate non‑China ramps where needed, and negotiate for durable, predictable permissions that keep product roadmaps on track.
What is a Validated End‑User (VEU) waiver?
A VEU waiver let approved companies ship certain U.S. semiconductor tools to specified China facilities without applying for individual licenses each time.
How long will new licenses take to obtain?
Case-by-case reviews often take three to six months, though timing depends on the tool type, end use, and agency workload.
