According to the Commodity Market Analysis System of Shengyi Society, the aggregated MDI market has been declining recently. The mainstream price for Shanghai goods (44V20, M20S, 5005) is 15900-16000 yuan/ton, while the mainstream price for domestic goods (PM200) is 16500-16600 yuan/ton. Currently, MDI devices in China are operating at medium to high loads, with fast market supply filling and downstream entry at low prices, resulting in average demand. Pre holiday replenishment has been basically completed, with a shortage of new orders and a lack of positive news to boost the market. It is expected that the aggregated MDI market will operate weakly in the short term.
