Polystyrene (PS) export prices in the United States remained unchanged this week, even as import prices recorded a minor decline. Market sentiment stayed steady to weak, supported primarily by demand from single-use applications such as food packaging, while broader consumption patterns across other downstream sectors continued to lag. An industry source told a Polymerduniya team member that this sluggish backdrop left overall momentum muted.
General-purpose polystyrene (GPPS) export prices were assessed at USD 1430–1450/mt FAS Houston, while high-impact polystyrene (HIPS) prices stood at USD 1495–1515/mt FAS Houston, both unchanged from the prior week. Feedstock styrene monomer (SM) spot prices were also stable at 42.10–42.20 cents/lb FOB US Gulf.
In Asia, polystyrene prices reflected mild downward adjustments. GPPS was assessed at USD 1040–1100/mt, down by USD 10–20/mt from the previous week, while HIPS stood at USD 1140–1200/mt CFR Far East Asia, easing by USD 10/mt at the lower end while steady at the higher end.
