Chinese viscose filament export offers rose by 150 USD per tonne on October 30, and Xinxiang Chemical Fiber's 31,200-tonne capacity is permanently exiting. Taurine prices reached 30.5 yuan per kg, up 90.63% year to date, with a leading producer's line shut for maintenance from mid-October.
Glufosinate prices reached 70,000 yuan per tonne, up 59.45% year to date, after an export rebate was cancelled and inventories fell.
These are Chinese specialty chemical price moves driven by capacity exits, maintenance and policy. The article notes that taurine demand could benefit as high fishmeal prices encourage substitution, but the link to feed commodity prices is indirect and not quantified.
