US PET Prices Rise 3.16% in August H2 on Tightening Supply and Higher Freight Costs

US Polyethylene Terephthalate (PET) market followed an overall bullish trend in August 2026, supported by tightening supply, reduced imports, higher freight costs, and rising production expenses. PET prices remained stable during the first half as ample inventories, muted trading activity, and weak downstream demand limited buying interest. Market participants adopted a cautious approach while awaiting pricing announcements and greater clarity on evolving tariff developments. Increased Asian imports were gradually absorbed without creating significant pressure on domestic PET prices, while firmer MEG costs provided limited upward support. During the second half, PET prices strengthened as reduced import availability, tightening supply, and uncertainty over potential tariff adjustments supported domestic offers. Rising container freight rates from Asia to the US increased replacement and landed costs, further strengthening seller pricing power. Looking ahead, higher freight charges, lower domestic inventories, and increasing production costs could provide near-term support, while seasonal demand softness and stronger Asian flows may create downward pressure later.
