Market Dynamics Intelligence Analysis of Methylene Diphenyl Diisocyanate (MDI)

I. Recent Price Trends
- Domestic Quotations: As of May 18, 2026, Shandong Yaoming Chemical Co., Ltd. and Hubei Qibajiu Chemical Co., Ltd. quoted RMB 17,000 per kilogram for solid-grade MDI, with market prices remaining at elevated levels.
- International Price Adjustments: At the beginning of 2026, the global MDI market experienced a broad-based price increase. Major international producers—including BASF, Huntsman, and Covestro—announced price hikes averaging USD 200–350 per metric ton (or equivalent in euros). For instance, Huntsman announced on February 17 a USD 260/ton increase for MDI products in the U.S. market; Covestro announced on February 19 a USD 0.10 per pound increase (approximately USD 220/ton) for MDI products in the North American market, effective March 1; and BASF announced on February 25 a USD 200/ton increase for MDI products in the ASEAN region.

II. Supply-Demand Analysis
- Supply Side:
- Global Capacity: As of February 2026, total global MDI capacity stood at approximately 11.55 million metric tons, with the top five global producers—Wanhua Chemical, BASF, Covestro, Huntsman, and Dow—collectively accounting for about 90% of global market share.
- Domestic Capacity: China has become the world’s largest MDI-producing country, with total MDI capacity reaching 5.5 million tons/year as of March 2026—a 15.3% increase over 2024. Wanhua Chemical leads globally with an annual MDI capacity of approximately 3.8 million tons.
- Capacity Expansion: Wanhua Chemical completed a technical retrofit project for its 1.5-million-ton/year MDI facility, adding 30,000 tons/year of liquefied MDI production capacity, thereby further optimizing its product portfolio.
- Demand Side:
- Global Demand: With global economic recovery and consumption upgrading, MDI demand continues to grow steadily. In emerging markets particularly, rapid development in infrastructure construction, the automotive industry, and the home furnishings sector is driving robust MDI demand growth.
- Domestic Demand: China’s MDI market is supported by policy-driven building energy-efficiency initiatives, automotive lightweighting trends, and household furniture consumption upgrades, sustaining moderate growth. The Chinese MDI industry’s market size is projected to reach RMB 56.37 billion in 2026, representing a 6.5% year-on-year increase from 2025.

III. Market Drivers
- Cost Pressures: Geopolitical tensions have exerted upward pressure on global energy prices. Crude oil and coal—key energy sources and raw material feedstocks for the chemical industry—have seen price increases that are directly transmitted into downstream chemical cost structures, contributing to higher MDI pricing.
- Tight Supply-Demand Balance: The global MDI supply-demand landscape is rapidly improving, with an estimated supply deficit of 650,000–1,070,000 tons anticipated between 2026 and 2027. As high-cost overseas production capacity continues to exit the market, the industry’s price floor is expected to rise systematically.
- Regulatory Impact: Increasingly stringent environmental regulations are prompting MDI producers to intensify R&D investment toward more eco-friendly and efficient MDI products. Meanwhile, evolving national trade policies—including anti-dumping investigations launched by the United States against Chinese MDI exports—are also influencing MDI market dynamics.

IV. Market Challenges and Risks
- Trade Barriers: The U.S. International Trade Commission (USITC) issued a final affirmative determination on material injury in its anti-dumping investigation concerning imports of MDI from China, concluding that the subject merchandise allegedly sold at dumped prices has caused or threatens to cause material injury to the domestic U.S. industry. This ruling will adversely impact Chinese MDI exports to the U.S.
- Competitive Landscape: The global MDI market exhibits an oligopolistic structure dominated by a handful of large-scale enterprises. However, with continuous technological advancement and increasingly diversified end-user demands, emerging players are gradually gaining visibility, intensifying competitive pressures across the sector.
- Raw Material Price Volatility: Key MDI feedstocks—including benzene, nitric acid, and chlorine gas—are subject to significant price fluctuations, directly affecting MDI production costs and, consequently, market pricing.

V. Outlook and Forecast
- Price Trend: Driven collectively by cost pressures, tightening supply-demand fundamentals, and regulatory influences, MDI prices are expected to remain at elevated levels in the near term. Nevertheless, intensifying competition and raw material price volatility may introduce periodic price fluctuations.
- Capacity Expansion: With continued global economic recovery and consumption upgrading, MDI demand is projected to sustain growth. Global MDI capacity is expected to expand further over the coming years to meet rising demand.
- Technological Innovation: The MDI industry will place increasing emphasis on green, intelligent, and high-efficiency development paradigms. Technological innovation aimed at enhancing MDI performance and application breadth, reducing production costs, and minimizing environmental impact will constitute a critical strategic direction for future industry advancement.
