SK Hynix, South Korea’s second-largest memory chipmaker and a critical supplier of high-bandwidth memory to Nvidia, is weighing strategic options for its semiconductor packaging facility in Chongqing, China. The company is considering bringing in an outside investor or potentially selling a stake in the operation, which could be valued at roughly $3 billion.
What’s actually at stake in Chongqing
The Chongqing plant, formally known as SK Hynix Semiconductor (Chongqing) Ltd., was established in 2013. It’s not a front-end wafer fabrication site. Instead, it handles backend operations: packaging and testing DRAM and NAND memory products.
The company is reportedly consulting with advisors on its options, though no official confirmation has been released. The $3 billion approximate valuation reflects both the facility’s current operational importance and the strategic constraints now limiting its future.
US export controls forced the calculation
US export controls on semiconductor equipment to China took effect on December 31, 2025, and they removed waivers that had previously allowed companies like SK Hynix to maintain and upgrade their Chinese operations.
Without those waivers, SK Hynix can no longer bring in the latest packaging and testing equipment to the Chongqing site. That doesn’t make the plant worthless overnight, existing tools still work. But it does put a ceiling on the facility’s capabilities at precisely the moment when advanced packaging is becoming more important, not less.
The pivot back to South Korea
While exploring options for Chongqing, SK Hynix is simultaneously pouring resources into domestic capacity. The company has plans for a $13 billion packaging facility in Cheongju, South Korea.
What this means for the memory market
SK Hynix is one of only three major DRAM producers globally, alongside Samsung and Micron. If SK Hynix brings in an outside investor for Chongqing, the identity of that investor matters enormously. A Chinese buyer could give Beijing access to packaging expertise that supports its domestic semiconductor ambitions. A financial investor might simply provide capital while Hynix retains operational control. Each scenario carries different regulatory and strategic implications.
HBM supply is already constrained, with SK Hynix commanding premium pricing for its latest-generation products. Any friction in the company’s packaging capacity, even temporary friction from restructuring, could amplify that tightness.
