06 Dec 2022 --- Royal DSM is implementing a “major reduction” of vitamin C production at its Jiangshan plant in China with immediate effect. The Dutch multinational says it will evaluate a return to normal production levels in 2023 after the Chinese New Year. The production slowdown comes amid “unsustainable” current pricing, which has made the continuation of usual output levels unviable at the China facility. However, the company’s Quali-C production in Dalry, Scotland, is not impacted.
