Due to the government’s powder curtailment policy, almost all yellow phosphorus factories have reduced production. After the contract was confirmed, the price of raw material rose sharply. The original quotation to customers has been far lower than the market price and even close to the production cost. In the case of almost no profit, our company still honestly and honestly maintained the original price for the customer, and quickly arranged the delivery. After the first pleasant cooperation, customers said that they have listed our company as their preferred supplier.
