Chempricehub analysis of maleic anhydride, long-short score: 1. The article shows that on January 5th, Yantai Wanhua's maleic anhydride auction was fully transacted, with the Yantai session transaction price at 4290 yuan/ton and the East China session transaction price at 4770-4780 yuan/ton, indicating strong market demand and stable prices. Combined with the spot market for maleic anhydride, the high auction success rate and high transaction prices reflect sustained support from downstream industrial demand (such as unsaturated polyester resin production). It is expected that spot prices will remain strong in the short term. Score +1 (generally positive) based on the positive signals released by the auction data, but attention should be paid to the regional price difference (Yantai lower than East China), which may indicate local supply pressure, with limited positive impact.
