Diethyl Carbonate prices in Japan rose 2.7% in Q2 2026 to USD 1,920.00/MT from USD 1,870.00/MT in Q1, extending a sharp reversal after prices had spent most of 2025 under sustained downward pressure. Chinese prices, which had absorbed the steepest decline of any market tracked in this report through 2025, rose 2.8% to USD 1,460.00/MT, continuing to recover from structural domestic oversupply and aggressive producer competition. Globally, the average rose from USD 1,720.20/MT in Q1 to USD 1,767.80/MT in Q2, a 2.8% gain, following a jump of nearly 17 percent in Q1 alone. For H2 2026, a global average of USD 1,650.00-1,950.00/MT is expected, with rising ethanol and ethylene carbonate feedstock costs likely to keep this market firm.
Diethyl Carbonate, commonly abbreviated DEC, is a colorless, low-viscosity solvent produced through the transesterification of ethylene carbonate with ethanol, or via direct reaction of ethanol with carbon monoxide and oxygen. It serves as a critical electrolyte solvent component in lithium-ion battery formulations, prized for its low viscosity and ability to improve low-temperature battery performance, alongside use as a fuel additive, a coatings and adhesives solvent, and an intermediate in pharmaceutical and agrochemical synthesis. Ethanol and ethylene carbonate feedstock costs, lithium-ion battery electrolyte demand, and Chinese domestic capacity utilization are what drive prices in this market.
The outlook for Diethyl Carbonate through H2 2026 stays firm, tracking rising ethanol and ethylene carbonate feedstock costs tied to the broader Strait of Hormuz-linked petrochemical cost environment. Resilient battery and coatings sector demand should continue supporting consumption, even as Chinese producers, having spent much of 2025 navigating structural oversupply, remain watchful of any renewed capacity-driven price pressure once the current feedstock-driven firming phase moderates.
The main upside risk is a further escalation of Middle East shipping disruptions affecting ethanol and ethylene carbonate feedstock costs, which could push prices higher than currently forecast. The main downside risk is a return to the structural Chinese oversupply conditions that drove prices sharply lower through most of 2025, which would cap or reverse the current recovery once the acute feedstock shock fades.
