In China, inventories of styrene monomer (SM) were rising and the feedstock benzene market remained soft. No factors were supporting the SM market. SM inventories were high at 174,300mt in East China as of Nov 5. Large volumes of cargoes are expected to be imported in December as well. In China, Hengli Petrochemical, Shandong Jingbo, the No.2 unit of ZRCC, Anhuijiaxi, Lianyungang Petrochemical and Xinyang TECH are currently undergoing turnaround and production was forecast to be low in November. However, in Shandong, Guoen Chemical, Dongming started up its new facility on Nov 9. Further, ZRCC would finish regular maintenance for its No.2 unit and also Lianyungang Petrochemical would finish turnaround in end-November. Under such circumstances, SM supply was perceived to be ample. Meanwhile, demand for derivatives was not strong and supply/demand was loose. There were no factors to support the SM market.
