Seoul moves to license exports of used chipmaking tools to China, tightening mature node supply
Kai Tanaka ·
South Korea’s Ministry of Trade, Industry and Energy began consulting industry this week on rules that would subject exports of used wafer fabrication equipment to China to case by case licensing, according to government notices and people briefed on the plan. The move targets a surge in secondhand tools flowing from Korean fabs and brokers to Chinese foundries, after the United States, Japan, and the Netherlands tightened sales of new advanced kit.
The change matters because China’s rapid build out at mature nodes has relied in part on secondhand immersion scanners, etchers, and deposition systems sourced from Korea based resellers. A licensing step for China bound shipments would raise costs and timelines for brokers, and it would complicate capacity additions at firms that supply SMIC and YMTC ecosystems.
What changes now
The draft expands the strategic goods list administered by the Korea Strategic Trade Institute to include categories of pre owned lithography tracks, plasma etchers, and CVD and ALD systems that enable patterning around 28 nanometer class production, the people said. Exports to destinations other than China would continue under general clearance, while China shipments would require end user and end use checks aligned with allied controls.
Officials are framing the measure as alignment with existing multilateral commitments, not a unilateral ban. Samsung Electronics and SK Hynix would retain separate processes for relocating in house tools between overseas sites, subject to existing U.S. waivers for their China fabs, the people said.
Who is affected
Korean brokers such as SurplusGlobal, which has built a global business refurbishing and trading used fab gear, face the most immediate impact. Chinese buyers have leaned on this channel to keep 12 inch capacity adds on schedule, alongside increasing procurement from domestic toolmakers such as NAURA, AMEC, and Piotech.
Tokyo Electron and Applied Materials do not sell new restricted tools into China without licenses, but their installed base still enters the used market when Korean and Taiwanese fabs retire lines. A tighter Korean gate would redirect some of that flow to Southeast Asia and India, where foundry projects at mature nodes are expanding with state support.
For the broader technology landscape, a Korean licensing step on used tools would nudge more Chinese investment into homegrown equipment and process development, while slowing the pace of easy capacity adds at mature nodes. It also underscores how export control coordination now reaches the secondary market, which affects pricing and delivery risks for global chip supply chains well beyond advanced logic.
