A widely shared report claiming that four major Japanese suppliers had halted new China orders for ArF and EUV photoresists has drawn intense attention, but the underlying evidence appears thin. The original article says the rumor named Tokyo Ohka, JSR, Shin-Etsu Chemical, and Fujifilm, and described a sweeping suspension of orders, technical support, and deliveries. Yet customs data cited in the same piece shows China imported 1,622 tons, 1,495 tons, 1,958 tons, 1,910 tons, and 1,939 tons of photoresist from Japan from January through May 2026, for a total of more than 8,900 tons, with no visible cliff-like drop in overall volumes.
The report also notes that a similar claim circulated before and that Japanese official channels, corporate websites, and industry media had not publicly reported the latest alleged cutoff. From there, the article shifts to the larger issue: why advanced photoresists matter so much to chip manufacturing, how Japanese companies built their edge through decades of process-specific formulations and customer co-development, and why an outright supply halt would not be a simple decision. It points to China’s growing role as a major photoresist market, Japan’s export-control timeline that has not formally included photoresists, rising domestic substitution in China, and South Korea’s expanding ArF and EUV-related capabilities. The piece argues that the bigger question is not the rumor itself, but the industry’s continuing anxiety over supply security.
