What is driving new DOA capacity investment in China's Fujian region?
A major integrated project in Gulei Development Zone, Fujian, includes a 150,000-tonne-per-year DOA unit, part of a 6.9 billion yuan investment scheduled for completion by December 2026. This project also builds 500,000 tonnes of butanol-octanol and 800,000 tonnes of acetic acid capacity. The strategic logic is upstream-downstream integration: the complex will consume propylene from the adjacent Gulei refinery and supply DOA to local PVC and plasticizer downstream users. This clustering reduces logistics costs and secures feedstock supply. For the DOA market, this represents a significant capacity addition that could shift regional supply-demand balances, especially as environmental regulations push substitution away from phthalate plasticizers toward non-phthalate alternatives like DOA.
