Chinese integration removed the largest merchant demand pool
Chinese paraxylene self-sufficiency reached roughly 96% through integrated refinery to polyester complexes commissioned over recent years, which is a complete reversal from the import dependence that shaped regional trade for two decades. Those complexes produce mixed xylene from their own reformers and consume it internally, which removes them from the merchant market entirely rather than merely reducing their purchases. Korean, Japanese and Southeast Asian producers who built capacity to serve Chinese import demand now compete for a considerably smaller pool. Commercially this destroyed margins across the region and the capacity has nowhere else obvious to go.
