Recently, Tokai Carbon Co., Ltd. announced that due to rising raw material costs, the company will increase the price of carbon black in the US market. The new price will be calculated by the company based on the current situation and will be announced to the outside world in the near future. The East China Sea Carbon said that the US shale oil revolution caused a decrease in the supply of carbon black raw materials and an increase in the cost of carbon black production. As the production cost of carbon black rises, the international carbon black giants announce price increases, and domestic carbon black enterprises are expected to follow the global price hike, thereby increasing their performance in the second half. Related carbon black concept stocks can focus on Black Cat shares, Jinneng Technology and so on.
