What factors influence the price of polyurethane self-skinning modified MDI?

The price of polyurethane self-skinning modified MDI is closely tied to the general MDI market conditions, while also being influenced by multiple factors including raw material and energy costs, supply-demand dynamics, industry competition, and the policy and trade environment.

The price of polyurethane self-skinning modified MDI is closely tied to the general market conditions for MDI itself, while also being influenced by a variety of factors—including raw material and energy costs, supply-demand dynamics, industry competition, and the policy and trade environment—as detailed below:

Cost-side factors

Fluctuations in the prices of basic raw materials: Pure benzene, aniline, and other substances are core raw materials for the synthesis of MDI, and their prices are closely linked to the petrochemical industry chain. Once international crude oil prices remain high, they will drive up the prices of derivatives such as pure benzene, thereby increasing the production costs of modified MDI. For example, if aniline producers in Shandong and the East China region experience production shutdowns, leading to a tight market supply, this will directly provide support for the prices of various MDI products, including self-skinning modified MDI.

Rising Energy and Logistics Costs: MDI production is a high-energy-consuming chemical process, and fluctuations in energy prices—such as those for natural gas and electricity—have a significant impact on costs. For instance, in 2024, European natural gas prices rose by 10% year-on-year, substantially increasing the burden on local modified MDI producers. In addition, transportation costs also play a crucial role. Adjustments in international and regional logistics rates and changes in transportation policies are all factored into pricing considerations by companies. When giants like BASF raise prices, they explicitly highlight the ongoing impact of rising transportation costs.

Supply-side factors

Equipment Maintenance and Capacity Fluctuations: The global MDI industry is highly concentrated, with major players such as Wanhua Chemical and BASF accounting for a significant share of total capacity. The operational status of these production facilities directly affects supply. For example, in early 2025, Takeda’s 400,000-ton-per-year plant in Japan was temporarily shut down, and Kukje’s 410,000-ton-per-year plant in South Korea underwent a month-long maintenance period. Such concentrated maintenance activities directly reduce the availability of spot supplies, thereby driving up prices for self-skinning modified MDI. Meanwhile, if newly commissioned capacity fails to deliver reliably, it will also slow down the replenishment of new supplies in the market, keeping the supply tight.

Low industry inventory levels: When inventories at major production plants are tight, traders tend to adopt a cautious attitude, holding onto their stocks and delaying sales. This market behavior further exacerbates the tight spot-market conditions, giving companies greater pricing power and supporting upward price trends. The “price support by industry giants and tight spot supply” scenario that has repeatedly occurred in the MDI market in 2025 is closely linked to low inventory levels.

Demand-side factors

Fluctuations in downstream industry demand: The core application areas of self-skinning modified MDI are automotive interiors and furniture. Changes in demand from these downstream industries directly affect its price. For example, the vigorous implementation of trade-in programs for automobiles and home appliances in China will boost demand for products such as car steering wheels and furniture armrests, thereby increasing the procurement volume of this material. Meanwhile, rising demand in regions such as Western Europe and North America will also drive growth in domestic exports, further fueling price increases. Conversely, if downstream industries enter a downturn and demand declines, it will force the price of modified MDI to fall.

Seasonal and Policy-Driven Demand: The market features traditional peak demand periods such as “Golden September and Silver October,” during which downstream production activities are vigorous, leading to a concentrated surge in demand for materials and driving prices to rise temporarily. Additionally, the expansion of emerging sectors like new energy and photovoltaics will broaden their application scenarios, providing long-term support for prices.

Trade and Market Environmental Factors

Changes in international trade policies: International trade tensions can disrupt market supply and costs. For example, in 2025, the U.S. launched an anti-dumping investigation into China’s MDI imports. If the anti-dumping duties are imposed, domestic enterprises’ export costs to the U.S. will surge, potentially forcing them to adjust their global supply strategies and thereby affecting the pricing of self-skinning modified MDI in different regions—and even reshaping the global price structure.

Market Dominance by Industry Leaders: Due to the high degree of industry concentration in the MDI sector, pricing actions taken by leading companies such as Wanhua Chemical and BASF carry significant demonstrative effects. When these companies raise their listed prices, it often triggers price coordination across the entire industry. Moreover, their pricing strategies aimed at safeguarding profit margins provide strong support for market prices of self-skinning modified MDI.
