According to the monitoring of business agency, on October 8, the mainstream negotiation focus of domestic BDO market was 29700-30300 yuan / ton (bulk water). Before the festival, the supply side support remained, the suppliers actively supported the market, the traders were reluctant to sell, the offer was increased by a narrow margin, and the auction price of Northwest goods source was high, and the market focus was running at a high level. However, with the influence of policies, the downstream industries in some areas have reduced their negative production, the operators’ purchase and marketing mentality has become cautious, and the market trading is deadlocked. After the festival, the maintenance devices were restarted one after another, the support of the supply side was weakened, and the supply and demand sides negotiated the game.
