After a slight increase in epichlorohydrin prices in September, the market remained relatively stable. By the end of the month, domestic prices closed at Dayang level. However, on October 8th, Qilu Petrochemical and Tianjin Chemical raised their prices to 18,000 yuan per ton, triggering a wave of price hikes across the market. The current round of increases exceeded 2,000 yuan, which was quite surprising. At this point, the market had not yet seen prices above 18,000 yuan, with contract customers accepting 18,000 yuan, while spot buyers were paying around 18,500 yuan.
The epichlorohydrin market has finally turned around from its long-term decline, with sharp price increases and an overall improvement in market sentiment. This sudden shift caught many by surprise, as the previous trend had been downward for months.
One key reason behind the price surge was the unexpected drop in domestic supply. In September, there had been expectations of a significant increase in production in October, leading to cautious market behavior and limited confidence in price movements. However, in October, several major producers faced operational issues. For example, Shandong Bohui Chemical's second phase 80,000-ton plant was temporarily shut down, Jiangsu Yangnong Chemical was undergoing maintenance, and Tianjin Chemical scheduled repairs for the month. Qilu Petrochemical also planned to halt operations on the 20th for overhauls. Meanwhile, Baling Petrochemicals reduced its foreign sales due to increased demand in September.
These disruptions led to a supply shortage that was even more severe than expected, intensifying the supply-demand imbalance. As a result, the trading atmosphere improved significantly, with transaction prices steadily rising. Low-cost sources became harder to find, and once the price broke through the 18,000 yuan threshold, it approached the 20,000 yuan mark.
Another factor contributing to the price increase was the growing demand from downstream sectors. Although the epoxy market remained relatively stable, demand started to pick up. Some previously idle companies resumed operations, and overall production rates increased. Solid one-step resin prices reached around 23,000 yuan, while liquid resin prices ranged between 27,000 and 28,500 yuan. Initially, weak epoxy resin demand had kept production rates low, reducing supply and creating a better market environment. However, as epichlorohydrin prices surged, buying interest picked up, further tightening supply and making procurement more challenging. This added to the active trading environment.
Additionally, changes in the import and export markets also influenced domestic prices. In August, China exported 1,003 tons of epichlorohydrin and imported 6,676 tons of chloropropane. Export volumes rose by 161% compared to the previous month, while imports fell by 63 tons. Russian supply sources have become tighter, and October imports are expected to remain low, adding pressure to the domestic market. Import prices in October were concentrated between 1,950 and 2,000 U.S. dollars (CFR).
In the short term, the sharp price increase is driven by supply shortages, marking a new phase for the epichlorohydrin market after years of decline. Traders began reluctantly selling products in October due to ongoing equipment instability and concentrated maintenance schedules. Domestic supply remains tight, and foreign trade associations are expected to raise their quotes in the second half of the month. The likelihood of higher external prices is increasing.
Currently, the domestic market trend needs close monitoring. While the factors supporting further price increases are strong, from an operational perspective, pushing prices higher may not be sustainable in the long run.
Plate Heat Exchangers (PHEs) are highly efficient devices used for heat transfer between two fluids. The U Series of plate heat exchangers is a specific design known for its compactness, flexibility, and high thermal efficiency.
