US potassium sorbate prices extended their upward trajectory in May 2026, building on the firm sentiment seen in April. The May market remained supported by a combination of strong seasonal demand, higher freight costs, and persistent cost pressures across key inputs. Importers faced continued tightness on the Shanghai–Houston shipping route, where elevated container rates and limited vessel availability kept landed costs high and reinforced bullish pricing expectations. Demand from core end-use sectors such as bakery, dairy, beverages, and nutraceutical gummies stayed resilient as manufacturers continued pre-summer stock building. Many buyers prioritized securing inventory ahead of peak production cycles, which further tightened spot availability. At the same time, stable sorbic acid production in Asia was offset by controlled export allocations, while higher caustic potash costs sustained elevated conversion expenses for producers.
