Syensqo has announced that it will reopen the synthetic vanillin production unit in Saint-Fons, France, by the end of 2025. The company said that this is coming in response to changing market conditions and demand from the European food, flavour and fragrance sectors. About 25 new jobs will be created.

Syensqo originally mothballed the plant in May 2024 because of inflation, declining demand and intensified competition, especially from Asian importers. However, recent developments, including the EU imposing 131% anti-dumping duties and minimum 232% additional duties in the US “should significantly reshape the competitive landscape, supporting regional producers”.

Saint-Fons, which continued to produce natural vanillin and hydroquinone, will complement production in Baton Rouge, Louisiana, and Zhenjiang, China, ensuring greater supply reliability in all three main regions. Syensqo added that this does not impact its intention to divest the Aroma Performance business.
