March 31 — On March 31, the maleic anhydride market in Shandong region remained stable. Solid maleic anhydride ex-factory prices hovered around 7,700–8,000 yuan/ton, while liquid maleic anhydride ex-factory prices were around 7,700 yuan/ton. The price of raw material n-butane rose, while the auction transaction prices in East China declined.

Chempricehub's analysis of maleic anhydride shows a bearish score of -0.5. The increase in n-butane prices has raised production costs, providing support for the spot price of maleic anhydride. However, the decline in auction transaction prices in East China reflects weak demand and increased supply pressure in the market. Under these combined factors, prices face short-term pressure, leaning slightly bearish.

For n-butane, the bullish score is 1. The rising market directly benefits spot prices, indicating tight market supply and demand or strengthened cost-driven factors, providing upward support for n-butane prices.
