US polyethylene exports hold record pace as Gulf Coast capacity ramps

United States polyethylene exports are running at record volumes as new Gulf Coast capacity reaches full rates and ethane-based cost advantages keep US resin competitive in virtually every importing region. HDPE blow molding and LLDPE film grades account for the majority of incremental export placements.

Latin America remains the most reliable outlet, with Brazilian and Mexican converters favoring US material on freight economics and short supply chains. Asian placements are more opportunistic, flowing when arbitrage windows open against Middle Eastern and Chinese supply.

Domestic demand is stable rather than spectacular. Packaging consumption continues to grow modestly, while construction-linked applications track a flat housing market. Producers are therefore expected to remain structurally export-oriented, with logistics capacity — packaging warehouses, rail availability, and container access at Houston — the binding constraint in peak months.

Analysts note that sustained export pressure from the US, alongside Chinese capacity growth, is reshaping global polyethylene trade flows and compressing the premium that European producers can sustain over world-market pricing.
