Two years of weak pricing conditions created a comfortable buying environment across the Maleic Anhydride market. Supply stayed loose and buyers had little urgency to act. That pattern changed quickly once energy disruptions moved beyond headlines and into feedstock costs.
The reaction did not begin inside Maleic Anhydride itself. It started in crude markets. Disruptions around key energy routes affected nearly 10 million barrels per day of supply expectations, while Brent crude remained more than 50% above January levels through mid-April. The impact then moved into n-butane, the key feedstock for Maleic Anhydride production.
China Maleic Anhydride Prices Deliver the Strongest Market Signal
China provided the clearest pricing signal. Market data showed China FOB Maleic Anhydride values moving from around USD 800/MT at the end of February to nearly USD 1,150/MT by mid-April. That represented a move of almost 44% within six weeks.
Rising Maleic Anhydride Costs Begin Impacting Downstream Industries
The speed mattered more than the number. Mid-March alone recorded weekly gains of 9.7% followed by another 11.1% increase a week later. Auction activity and stronger feedstock economics helped establish a higher market floor after months of weakness.

The impact now reaches further down the chain. Unsaturated Polyester Resin (UPR) producers are among the first affected because MA costs move into construction, automotive, and marine applications within one procurement cycle. BDO demand has also been expanding by roughly 4–5% annually, led by spandex growth in China and India.
Maleic Anhydride Oversupply Continues to Limit Market Upside
Still, oversupply remains a counterweight. China’s MA exports increased 36% in 2024, followed by another 15% year-on-year rise. That explains why the initial rally later started losing momentum.
What the Latest Maleic Anhydride Market Shift Means for Procurement Teams
