January 14 - On January 14, Panjin Ruide Chemical Co., Ltd.'s phthalic anhydride (PA) plant has a capacity of 100,000 tons. The operation rate of the PA equipment is low, and inventory is limited. The ortho-xylene-based PA is quoted at 6,160 yuan/ton. Chempricehub's analysis of PA gives a long-short score: 1. The article points out that the low operation rate of PA equipment and limited inventory indicate a significant reduction in supply, which may push up spot prices. The current quotation of 6,160 yuan/ton, coupled with tight supply factors, is favorable for the market and supports price increases. Score +1 (moderately positive) based on the positive impact of supply constraints on spot prices, but demand-side factors are not mentioned, so it does not reach a major positive level.
