Maleic Anhydride Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Maleic Anhydride Market Trends and Insights

Surging Adoption of Recycled-PET UPR in European Construction

In response to EU Regulation 2022/1616, which mandates recycled content in plastics, and the 2024 Ecodesign Regulation, requiring digital product passports to certify circular attributes, European composite producers are taking proactive steps^{[1]European Union, “Regulation 2022/1616,” eur-lex.europa.eu}. They are blending post-consumer PET with maleic-anhydride-modified unsaturated polyester resin. This strategy not only helps them secure green-building credits but also enables a reduction in embodied carbon. Countries like Germany, France, and the Netherlands are leading the charge, channeling their UPR demand into these eco-friendly blends. With passport obligations set to take effect in July 2026, the adoption of these practices is poised to accelerate, solidifying maleic anhydride’s pivotal role as a compatibilizer in the realm of low-carbon construction composites.

Capacity Additions of N-Butane Plants Lowering Feedstock Cost

In 2024, n-butane oxidation dominates with a commanding share of global capacity. Notably, new facilities in China and Oman, leveraging cutting-edge vanadium-phosphate and tri-leaf catalysts, are achieving high yields^{[2]BASF SE, “Factbook 2024,” basf.com}. These advancements not only enhance productivity but also mitigate benzene emissions, allowing these facilities to dodge EPA NESHAP compliance costs. Furthermore, feedstock dynamics tilt in favor of butane, while producers in the Asia-Pacific region shelled out less for butane compared to benzene. This pronounced cost disparity is fueling a surge in conversions and greenfield projects across three continents, solidifying the n-butane route's competitive advantage.

Lightweight SMC Panels for EVs Boosting UPR Demand in North America

In 2025, North American electric vehicle (EV) production surged, marking a robust year-on-year growth. OEMs are now turning to sheet-molding-compound battery enclosures, utilizing unsaturated polyester resin (UPR) and maleic anhydride for each vehicle. The USMCA's local-content regulations are pushing for domestic resin production. This is underscored by the launch of new facilities in Illinois and West Virginia, both of which became operational in 2024. With the rising popularity of gigacasting, the appetite for flame-retardant SMC grades, known for their superior wet-out properties, is set to eclipse the growth of traditional automotive composites, leading to an uptick in regional maleic anhydride consumption.

Rising 1,4-BDO Demand for Spandex and PBT in Asia

Asian textile and electronics clusters are utilizing 1,4-BDO to produce spandex and PBT. By continuously hydrogenating maleic anhydride to BDO at 190 °C, a high yield is achieved. This success has spurred integrated investments, such as BASF’s Zhanjiang Verbund, which is set to commence downstream oxo-C4 units in 2025. China, India, and Vietnam have collectively boosted their PBT capacity, and spandex fiber production has also increased. With a captive BDO supply, producers are insulated from the volatile commodity prices of maleic anhydride, allowing them to command a premium on high-purity grades.

Global Oversupply Driven by New Chinese Capacities

In 2024, China unveiled new capacity, spearheaded by Hengli's complex, pushing China's global output share past the 70% mark. Ex-works prices plummeted, a stark contrast to North America's spot prices, igniting a surge in exports. Meanwhile, utilization rates dipped. Western players, grappling with elevated fixed costs, began shuttering plants: Huntsman ceased operations at its Moers facility in mid-2025, and Nan Ya put its Taiwan site on hold in late 2024. In a bid to navigate these challenges, industry incumbents are now focusing on high-purity molten supplies and specialty copolymers, areas where competition from China remains limited.

Stricter OECD Benzene-Emission Caps Raising Compliance Cost

In response to EPA NESHAP and similar EU regulations, which impose benzene limits, units utilizing the benzene route have been compelled to adopt oxidizers and implement continuous monitoring. These measures have escalated operating costs and incurred significant capital expenditure. Consequently, this financial burden has led Huntsman and Nan Ya to shutter their plants and has dissuaded the establishment of new benzene-based facilities. Reflecting this trend, every capacity announced post-2024—including Hengli in China, ABP in Oman, and Indian Oil’s proposed unit in Panipat—has pivoted to n-butane oxidation, signaling a pronounced shift away from benzene technology.

Segment Analysis

By Product Type: Unsaturated Polyester Resin Dominance Reflects Construction and EV Composites Momentum

Unsaturated polyester resin secured 50.15% of the maleic anhydride market share in 2025 and is tracking a 4.98% CAGR to 2031, ahead of the overall market. European regulations are pushing for the use of recycled-PET blends. In North America, electric vehicle (EV) battery enclosures are utilizing maleic anhydride for each vehicle. These applications act as a buffer, shielding volumes from the cyclical downturns often seen in commodity resins. Demand for 1,4-BDO is on an annual growth trajectory, driven by investments in spandex and PBT across Asia. While the usage of lubricant additives has seen a decline as combustion engines wane, maleic anhydride copolymers are thriving. These copolymers, utilized in water treatment and bio-based packaging, are helping to mitigate the downturn in lubricants. Additionally, fumaric and malic acid derivatives are witnessing steady annual growth, primarily fueled by their use as beverage acidulants.

Specialty products, despite their lower volumes, command significant margins. For instance, bio-based succinic-acid copolymers are achieving impressive premiums in the premium packaging sector. Producers are strategically tapping into these niche markets to navigate the challenges of oversupply. Notably, Japanese research and development is making strides, focusing on the furfural-route maleic anhydride and its downstream green copolymers. This dual landscape not only solidifies unsaturated polyester's central role in the maleic anhydride market's revenue but also highlights the diversification of profit pools through its derivatives.

By Raw Material: N-Butane Route Ascendancy Driven by Yield, Cost, and Regulatory Advantages

The n-butane route dominated 70.45% of production in 2025 and is projected to grow faster than the overall maleic anhydride market. Butane oxidation eliminates benzene emissions and captures co-product hydrogen, delivering lower cash costs and simpler permitting. BASF's tri-leaf catalyst boosts yield and reduces reactor pressure drop, translating to significant savings, especially with energy being the second-largest variable cost. 

Benzene-based production, though declining in share, is forecast to grow at 4.72 percent CAGR through 2031, faster than the overall market, because surviving benzene-route plants are concentrated in integrated petrochemical complexes where benzene is a low-cost byproduct of naphtha cracking and where producers have already amortized compliance investments. Surviving benzene units remain competitive only where benzene is an internal cracker by-product, for example, Huntsman’s U.S. Gulf Coast sites co-located with UPR reactors. Even there, continued operation hinges on already-amortized scrubbers.

By Physical Form: Molten Grade Gains Traction as Integrated Producers Co-Locate

Solid forms (flake and prill) accounted for 60.78% of the 2025 volume because they store and ship easily across oceans. Molten supply, though smaller, is climbing at 4.93% CAGR thanks to integrated resin complexes in Illinois, 

In Kuantan and Yantai, heated pipelines and railcars have managed to reduce energy consumption in packaging and re-melting. This reduction is particularly significant given that carbon pricing in Europe is projected to increase. Molten distribution has an economic radius, leading to a concentration of uptake in areas where UPR plants are adjacent to maleic anhydride reactors. Europe, however, is falling behind. The continent's fragmented resin plants find it uneconomical to invest in dedicated hot-tank logistics, resulting in a dominance of flakes in EU trade.

By End-User Industry: Construction Leads, but Automotive and Electronics Diversify Demand

Construction consumed 62.23% of the maleic anhydride market size in 2025 and is growing at a 4.78% CAGR to 2031. India's infrastructure initiatives and the EU's push for a circular economy are fueling this growth. The automotive sector is reaping the rewards of a surge in demand for EV-driven composites and parts, thanks to the USMCA regulations. In the electronics realm, there's notable growth largely driven by the demand for connectors and sensor housings, specifically those made from PBT sourced from BDO. While the food and beverage and specialty chemicals sectors collectively represent a smaller portion of the market, they are witnessing stable growth, bolstered by regulations. This stability helps insulate overall demand from the declining trend of oil additives in ICE lubricants.
