Polystyrene (expandable)

HS 390310 covers polystyrene in primary forms, predominantly expandable polystyrene (EPS), a petrochemical derivative heavily reliant on styrene monomer priced off crude oil and benzene. China, South Korea, and Taiwan dominate global supply, making country-of-origin declarations critical for anti-dumping duty exposure in the EU and US markets. Demand is closely correlated with construction starts and consumer goods packaging cycles, making the product moderately price-sensitive to both energy shocks and macroeconomic downturns.
