In what may be one of the quietest weeks on record for West Coast South American polypropylene, both injection-grade and copolymer prices remained unchanged. As of August 15, 2025, CFR West Coast South America offers were logged at USD 980–1010/mt for PP injection and USD 1040–1070/mt for PP copolymer, exactly mirroring their levels from a week earlier.
This price plateau suggests a market momentarily cloaked in stability, even as global dynamics continue to shift. Elsewhere, volatility persists: buyers in Brazil and neighboring markets have been weighing increased inventories, while Asian FOB prices and transport dynamics continue to influence regional parity and import competitiveness.
Historically, markets like West Coast South America have responded to shifts in freight or Asian offers, especially during tariff-related disruptions or supply shifts. But this week’s flatlined pricing could indicate a lull in action, possibly reflecting a wait-and-see sentiment as buyers digest near-term economic signals or potential freight cost movements.
