[It is difficult for product price increases to offset the increase in raw materials, and the profits of the tire industry are under pressure] On October 22, incomplete statistics found that since September, more than 80 companies have issued more than 100 price increase letters, and the price adjustments cover all-steel tires, semi-steel tires, engineering tires and other categories. The mainstream increase range is between 2% and 5%, and some specifications have increased by as much as 6%. This is the fourth round of price increases in the tire industry this year. Zhu Hong, deputy secretary-general of the China Rubber Industry Association, said that rising raw material prices in 2026 will have an impact on the rubber industry. The prices of the three main raw materials, natural rubber, synthetic rubber and carbon black, have surged simultaneously, accounting for more than 60% of tire costs in total, and raw materials as a whole accounting for more than 70% of production costs. As of the end of September, the raw material cost index for semi-steel tires and all-steel tires has increased by about 25% year-on-year. It is worth noting that currently, the increase in raw material costs in the tire industry has outpaced the increase in selling prices of related products. (Securities Daily)
