Samsung, SK granted indefinite US waiver on chip gear supplies to China
Despite Washington’s move, uncertainties remain and the chipmakers will likely cut their China production, analysts say

Samsung Electronics Co. and SK Hynix Inc., the world’s two largest memory chipmakers, have been granted an indefinite waiver on semiconductor equipment supplies to their factories in China – a move expected to help their technology advancement and strengthen the global chip supply chain.
The US government allowed the two South Korean chipmakers to acquire US-made chipmaking devices without separate US approvals, Seoul’s presidential office said.
“The US decision has greatly eased uncertainties over Korean chipmakers’ operations and investments in China,” Choi Sang-mok, senior presidential secretary for economic affairs, told a media briefing on Monday.
The US government has already notified Samsung and SK of its decision, indicating that the move is in effect, according to Choi.
Last October, the US government unveiled sweeping chip-related export controls on China, while granting some leading chipmakers, including the Korean duo and Taiwan’s TSMC, a one-year reprieve to allow them to upgrade their facilities there.

Samsung and SK have since halted new investments in China while awaiting Washington’s next move given the approaching end of the one-year grace period.
In May, industry sources said the US Commerce Department is in talks with Korean officials to work out separate equipment import standards to enhance non-Chinese chipmakers’ business predictability and minimize global supply chain disruptions.
Following the US government’s latest decision, Samsung and SK Hynix will be included on the Commerce Department’s “validated end user (VEU)” list, which means they will be allowed to keep supplying certain US chipmaking tools to their China factories without obtaining permission.
Samsung and SK welcomed the US decision, saying they will do their best to stabilize the global semiconductor supply chain.
In China, Samsung operates a NAND flash memory chip plant in Xian and a chip packaging facility in Suzhou. SK Hynix runs a DRAM chip plant in Wuxi, a NAND plant in Dalian and a packaging factory in Chongqing.

UNCERTAINTIES REMAIN
Despite the indefinite US waiver, however, uncertainties remain over the Korean chipmakers’ business in China given the ongoing chip supremacy tug of war between Washington and Beijing – Korea’s two largest export partners.
According to the so-called guardrails or detailed guidelines of the US CHIPS and Science Act finalized on Sept. 21, chipmakers cannot expand output in China and “foreign countries of concern” by more than 5% for advanced chips and 10% for older technology, or legacy chips, over the next decade.
Legacy chips, as defined by the US, are logic chips produced with 28 nm or larger technology; DRAM chips manufactured with an 18 nm or higher process node; and 128-layer or thinner NAND flash memory chips.

The CHIPS Act provides up to $52.7 billion in subsidies to chipmakers that invest in new production facilities in the US but allows Washington to take back incentives from the recipients if they violate guardrail provisions.
Samsung is building a $17 billion foundry factory in Taylor, about 25 km from Austin, where its current contract-manufacturing operations are located.
Analysts expect Samsung and SK Hynix to gradually slash their investments in China and reduce their production volumes in the country to limit any collateral damage from the US-China dispute.
