Following the holiday, isooctanol prices fluctuated upward
According to the SunSirs Commodity Market Analysis System, the price of isooctanol stood at 9,066.67 RMB/ton on May 9. This represents a fluctuating upward trend compared to the 8,800 RMB/ton recorded at the beginning of the month—marking an increase of 3.03%—though it remains 2.16% lower than the price of 9,266.67 RMB/ton observed on April 1. Following the holiday period, isooctanol prices trended upward in a fluctuating manner relative to late April levels, yet they remained below the prices seen at the start of April. In 2026, China's isooctanol market finds itself at a critical juncture characterized by a tight balance between supply and demand, alongside structural transformation. Influenced by a confluence of factors—including newly added production capacity, risks associated with cost volatility, and increased export volumes—isooctanol prices have undergone significant adjustments. Post-holiday, operating rates at isooctanol production facilities declined, resulting in a temporary tightening of supply; consequently, prices rebounded and rose in the wake of the holiday period.
Support from High Propylene Costs Began to Weaken
According to the SunSirs Commodity Market Analysis System, as May began, the resumption of operations at propylene production facilities increased; consequently, propylene supply rose while demand remained sluggish. Following the holiday period, propylene prices experienced volatile declines. However, uncertainties regarding geopolitical tensions in the Middle East appear to be propping up raw material costs—preventing prices from "bottoming out"—and propylene prices therefore remain at relatively high historical levels. The post-holiday price decline appears to be more of a technical correction following a rapid upward surge rather than a fundamental trend reversal. The sustained high level of propylene prices is bolstering the price floor for isooctanol; furthermore, manufacturers' increased willingness to defend their pricing is providing support to the lower end of the octanol price range. Nevertheless, the post-holiday drop in propylene prices has resulted in a weakening of cost-based support for high-priced isooctanol.
Isooctanol Operating Rates Declined
At the end of April, the operating rates of isooctanol producers rose to 98%; however, following the holiday period, plant operating rates declined to 88%, resulting in a reduction in the supply of isooctanol. Post-holiday, some production units remain scheduled for maintenance—specifically, the 330,000-ton unit at Shuguang is slated for its first phase of maintenance in mid-to-late May—suggesting that supply may contract further in the near term. This tightening of supply serves to support an upward trend in isooctanol prices.
2026 marks the peak period for the commissioning of new capacity within the isooctanol industry. This concentrated influx of new capacity is expected to exert a significant impact on the market's supply-demand balance, thereby intensifying pressure from overcapacity. In the short term, industry operating rates are subject to wide fluctuations driven by shifts in market supply and demand, as well as corporate maintenance schedules; however, over the medium to long term, the amplitude of these fluctuations is expected to narrow. Specifically, the annual operating rate for 2026 is projected to stabilize within a narrower range of 80% to 85%. Furthermore, supply-side elasticity is expected to diminish due to factors such as the commissioning of new facilities, periodic production restrictions imposed for environmental protection purposes, and adjustments made by enterprises to manage profit margins. Overall, the landscape of isooctanol overcapacity is set to become even more pronounced, leading to increasingly fierce market competition.
Market Outlook
According to the Octanol Product Data Analyst at SunSirs, regarding the cost side: following the holiday period, propylene prices declined, thereby weakening cost support for isooctanol. However, influenced by geopolitical factors affecting crude oil, propylene enjoys significant upward support, limiting its downside potential; consequently, downward pressure on isooctanol prices in the near term remains insufficient. Regarding the supply side: the addition of substantial new production capacity has intensified overall supply pressure on isooctanol. Nevertheless, post-holiday reductions in operating rates at isooctanol production facilities have led to a temporary tightening of supply, thereby providing support for price increases. Regarding the demand side: downstream plasticizer manufacturers have maintained stable operating rates, providing steady support through essential demand for isooctanol; furthermore, an increase in export volumes offers some additional upward support for prices. Looking ahead, while costs remain elevated, the supply landscape is characterized by short-term tightness juxtaposed with a medium-to-long-term surplus. On the demand front—despite the support provided by exports—overall demand lacks structural growth, making it difficult to fundamentally alter the prevailing market condition of oversupply. Consequently, while upward momentum for isooctanol prices is limited, geopolitical factors serve to restrict the potential for significant price declines; the market is therefore expected to exhibit weak, volatile fluctuations, trending toward stabilization in the near future.
