March 12th News: On March 12th, Yantai Wanhua's maleic anhydride auction: the East China session had an auction volume of 90 tons, with no transactions completed. Chempricehub's analysis of maleic anhydride, with a long-short rating: -1. The failure of the maleic anhydride auction to secure any bids indicates insufficient market demand and emerging pressure on the supply side, exerting a bearish impact on spot prices. Specifically, the lack of transactions for the 90-ton auction in the East China session reflects strong buyer caution or low price expectations, which may undermine confidence in the spot market and lead to short-term downward pressure on prices.
