Mostly True
Semiconductor equipment sourced from the United States and Japan has been found to contain Chinese-origin rare earth materials and graphite, underscoring the depth of China's role in the semiconductor supply chain despite ongoing efforts by the US and Japan to restrict exports of advanced equipment to China.
Equipment purchased from American and Japanese suppliers has been found, upon inspection, to include rare earth materials and graphite originating in China, according to a review of the claim. The finding highlights a supply chain paradox: even as Washington and Tokyo tighten controls on semiconductor equipment exports to China, hardware produced outside China continues to depend on Chinese raw materials.
China dominates global production of rare earth elements and graphite, materials used across semiconductor manufacturing equipment and processes. The presence of these Chinese-origin inputs in US- and Japanese-made tools suggests that export controls targeting finished equipment do not eliminate Chinese dependence upstream, where Beijing holds greater influence over materials supply than over machinery.
The report on the matter was published under the headline "美·日 반도체 장비 샀는데… 까보니 중국산 희토류·흑연" — "Bought US and Japanese semiconductor equipment... opened it up to find Chinese rare earths and graphite" — and drew on a set of primary sources to support the finding.
The discovery points to a gap in current policy frameworks: restricting equipment exports addresses one layer of the supply chain, but raw material inputs remain concentrated in China. For Korean industry, where Samsung Electronics, SK hynix and domestic equipment makers depend on both foreign tools and global materials markets, the finding adds to concerns about the resilience of critical material sourcing.
Whether the specific equipment models or suppliers involved can reduce Chinese material content remains unclear, and the report does not establish the extent to which such inputs could be substituted from other origins.
The claim, which holds that US- and Japanese-made semiconductor equipment has been found to contain Chinese rare earths and graphite upon inspection, stands up on its core point, making it Mostly True.
