As of October 11, 2026, the spot market for phthalic anhydride in China has shown a strong consolidation with a predominantly upward trend.

The main factors supporting the recent strength in prices are plant maintenance and low inventory levels among manufacturers in China.

2. Signal Status Determination
The current deviation change combination is (－, ＋, ＋), corresponding to a strong consolidation signal (biased towards bullish).
3. Trend Direction Conclusion
The current phthalic anhydride price trend is oscillating (with a bullish bias). The reason is that the changes in the 5-day, 10-day, and 20-day moving average differences from the previous day are not entirely consistent, which does not meet the criteria for a clear upward or downward trend, thus falling within an oscillating range. The bullish bias comes from the continuous rise in the medium- to long-term moving average differences, with strong support from the lower moving averages.
4. Location and Spatial Reference

6. Fundamental Dynamics Reference
Recently, Chinese phthalic anhydride manufacturers have been conducting more plant maintenance, leading to a tightening of spot supply: Zhenjiang Liancheng Chemical's 120,000-ton phthalic anhydride unit has been shut down for maintenance, with oversold inventory, and the price on October 10 was raised to 10,350 CNY/ton; Shijiazhuang Bailong Chemical's 80,000-ton naphthalene-based phthalic anhydride unit is replacing catalysts, with limited inventory mainly for internal use, and the price on October 10 was raised to 10,200 CNY/ton; Changzhou Xinyang's 100,000-ton phthalic anhydride facility is operating at around 60% utilization rate, with low inventory, and the price on October 9 was raised by 250 CNY/ton to 10,300 CNY/ton, with orders being accepted on a limited basis.
