Table 1: Domestic Dimethyl Carbonate (DMC) Price Summary (Unit: Yuan/Ton)

Based on the Shandong region as a benchmark, DMC closed today at 6,475 yuan/ton, representing a decrease of 75 yuan/ton compared to the previous trading day. The domestic DMC market exhibited a weak downward trend today, with negotiation centers shifting slightly lower and trading activity remaining subdued. On the supply side, units that had undergone maintenance or shutdowns are gradually restarting, and some plants have increased their operating rates. Consequently, spot supply is increasing, alleviating the previous tightness in market availability. To reduce inventory pressure accumulated during the holiday period, some plants have shown stronger willingness to sell, adjusting their offers flexibly downwards, leaving room for discounts in actual negotiations. Demand performance has been moderate; end-users show low enthusiasm for stockpiling, downstream buyers mostly maintain rigid demand procurement, and sentiment is characterized by wait-and-see attitudes. Traders are following market trends cautiously, resulting in limited volume in actual transactions.

3. Price Forecast

Looking ahead, the market may remain generally stable with minor adjustments. Short-term trends will continue to be supported by dual factors: tightening supply and pre-holiday restocking.

4. Related Products Status

Propylene Oxide: Today, the domestic propylene oxide market underwent narrow-range adjustments, with mainstream prices holding steady. Shipment conditions for active plants were mixed, leaning slightly towards weakness, but inventories remained low and manageable. Most suppliers maintained stable pricing, while a few made narrow adjustments. Current cost-side support has cooled, but crude oil and propylene have rebounded strongly, influencing market sentiment. Downstream demand remains cautious, with conservative purchasing behavior, and stakeholders continue to engage in wait-and-see dynamics.

Polycarbonate (PC): Today, the domestic PC market operated in a wait-and-see consolidation mode. By the afternoon close, the negotiation range for domestic-grade PC in East China was 13,200–15,250 yuan/ton, with the overall center remaining roughly stable compared to yesterday. Latest ex-factory prices from domestic PC producers held steady or increased by 500–600 yuan/ton. Zhejiang Petrochemical's auction opened high, with two rounds transacted at a price 400 yuan/ton higher than last week. In the spot market, both East and South China regions continued a pattern of stalemate and consolidation. Although cost structures and supply constraints in the industrial chain still provide strong support for high PC prices, downstream rigid demand has weakened significantly. Market participants hold cautious and bearish sentiments, prioritizing stable pricing while selling according to market conditions. Discounts are negotiable in actual transactions, but transaction volumes remained low throughout the day.
