India has one small PO producer, Manali Petrochemicals in Chennai (indicative). Polyol and propylene glycol demand is met largely by imports from China, Southeast Asia, Saudi Arabia and Korea (indicative). No world-scale Indian PO project was confirmed in sources reviewed.

Position by region

RegionPosition
USPO/TBA and PO/SM economics tied to MTBE and styrene co-product values (indicative).
EUHigh cost; some chlorohydrin closures; HPPO at Antwerp competitive (indicative).
IndiaNearly fully import-dependent for PO derivatives; polyols and PG imported.
ChinaAbout 58% of capacity, now a net exporter of PO derivatives (indicative); prices hit annual highs in January 2026 on tight supply (Mysteel headline).
JapanSumitomo CHP; small domestic market.
Middle EastSadara (Dow-Aramco) HPPO and Petro Rabigh CHP; exports polyols.
