Market Intelligence Report on Isoprene (m-Isoprene) – Recent Commodity Market Dynamics

I. Price Trends
- National Average Price: As of May 22, 2026, the national average price of m-isoprene across major domestic markets stood at RMB 7,971.2 per metric ton, down by RMB 90/ton (a decline of 1.12%) from the previous day. Over the past week, prices have exhibited volatile downward movement, with the largest single-day drop—6.02%—occurring on May 18, representing the steepest decline in recent weeks.
- Regional Price Disparities: Prices in the East China region ranged between RMB 7,800–8,500/ton; those in South China ranged between RMB 8,000–8,200/ton; prices in Northeast China spanned RMB 7,500–9,000/ton; and the Central China region posted a price of RMB 7,300/ton. Regional price variations persist, with East and South China commanding relatively higher price levels.
- Enterprise Quotations: Shandong Laya Chemical Co., Ltd. quoted RMB 10,000/ton for its national-standard-grade product; Suzhou Senfeida Chemical Co., Ltd. quoted RMB 7,500/ton for its 99%-purity grade.

II. Supply and Demand Dynamics
- Supply Side: The Huizhou ISCO plant is scheduled for planned maintenance shutdown, potentially reducing market supply. However, overall, m-isoprene capacity utilization remains suboptimal: as of end-2024, China’s total annual m-isoprene production capacity reached 480,000 tons, yet average annual output amounted to only 263,000 tons—implying a capacity utilization rate of less than 55%.
- Demand Side: Downstream demand remains generally weak, with spot transactions limited to sporadic, just-in-time procurement. Most downstream buyers are fulfilling pre-existing orders and contractual commitments. Moreover, weakening downstream product prices have eroded buyers’ willingness and ability to pay higher prices for raw materials, resulting in cautious, low-price-driven purchasing behavior.

III. Related Markets and Cross-Market Influences
- Crude Oil Market: U.S.–Iran negotiations significantly impact international crude oil prices—and thereby indirectly affect the m-isoprene market. Recently, talks have stalled, rekindling market concerns over potential supply disruptions and pushing up global oil prices. Yet, contrary to expectations, m-isoprene prices declined, indicating that crude oil price movements exert only limited direct influence on the m-isoprene market.
- Pyrolysis C5 Market: Pyrolysis C5 serves as the primary feedstock for m-isoprene production; thus, its market dynamics directly influence m-isoprene pricing. Recently, the pyrolysis C5 market has stabilized with a slight downtrend, exerting moderate cost pressure on m-isoprene producers.

Analysis & Assessment

I. Reasons for Price Decline
- Supply–Demand Imbalance: Although scheduled plant maintenance may modestly constrain supply, overall capacity utilization remains low—indicating relatively ample supply. Conversely, downstream demand remains sluggish; weakening downstream product prices further impair raw material affordability, resulting in structural oversupply and downward price pressure.
- Market Sentiment: Overall market sentiment is subdued. Downstream buyers adopt a “buy-low” strategy, releasing demand only selectively and cautiously. While trading activity has shown marginal improvement, transaction volumes remain insufficient to provide meaningful price support.

II. Causes of Regional Price Differentials
- Regional Economic Development Levels: East and South China feature relatively advanced economies and robust downstream industrial clusters, generating comparatively stronger demand for m-isoprene and supporting premium pricing.
- Transportation Costs: Northeast and Central China are geographically distant from major consumption centers, incurring higher logistics costs—contributing to comparatively lower local prices.

Outlook

I. Short-Term Outlook
- Price Trend: M-isoprene prices are expected to continue fluctuating downward in the near term. Planned maintenance will exert only limited tightening effect on supply, while persistent downstream weakness is unlikely to reverse rapidly—maintaining an imbalance favoring supply.
- Trading Activity: Spot transactions will remain dominated by just-in-time, low-volume purchases. Continued softness in downstream product pricing will further dampen raw material procurement enthusiasm, sustaining a subdued trading atmosphere.

II. Long-Term Outlook
- Improved Capacity Utilization: Advancements in technology and enhanced industrial chain coordination are expected to gradually lift m-isoprene capacity utilization rates. Adoption of novel integrated processes—such as high-efficiency extraction–distillation coupling—will improve product purity and yield while lowering production costs and bolstering competitiveness.
- Optimized Demand Structure: Expansion into new application areas and emergence of innovative use cases will refine demand composition. High-purity and customized m-isoprene products are projected to gain increasing share in high-end sectors—including electronic chemicals, pharmaceutical intermediates, and new-energy materials—driving sustainable demand growth.
- Price Stabilization and Recovery: Under the dual impetus of rising capacity utilization and optimized demand structure, m-isoprene prices are anticipated to gradually stabilize and recover over the medium to long term. Nevertheless, long-term price trajectories will remain subject to multiple external influences—including crude oil markets, pyrolysis C5 dynamics, and broader macroeconomic conditions.
