April 15th News: On April 15th, Yantai Wanhua's maleic anhydride auction: 90 tons were offered in the East China session, 30 tons were traded, with a transaction price of 7,700 yuan/ton. Chempricehub's analysis of maleic anhydride, long-short score: -1. Only 30 tons were traded out of the 90 tons offered, with a transaction rate of 33.3%, indicating weak market demand. Although the transaction price of 7,700 yuan/ton does not provide historical comparison, the low transaction rate reflects oversupply or insufficient demand in the spot market, posing a generally bearish impact on the spot price of maleic anhydride, which may lead to short-term downward pressure on prices.
