The bad effects of the "special protection case" for American tires are increasingly evident. According to statistics released by the Huangpu Customs on the 23rd, in the first three quarters of this year, nearly 29,000 tires of pneumatic rubber were exported from Guangdong Province, a decrease of 22% compared with the same period of last year. Among them, exports to the United States dropped dramatically. Thirty-two. Since 2009, the export of tires in Guangdong, an important producer of tires in China, has been low, with exports of nearly 3.5 million in September, a year-on-year increase of 13% and a decrease of 5.8% from the previous month. The United States is the largest market for the export of tires in Guangdong. In the first three quarters of this year, Guangdong Province exported more than 9.5 million tires to the United States, a decrease of 32%, accounting for 33% of total exports; during the same period, exports to Africa, the EU and Latin America A decline of more than 20 percent; exports to Hong Kong rose by 18 percent, reaching nearly 3 million. It is reported that China is the world’s largest tire exporter, producing nearly 40% of its tires, of which one-third is exported to the United States. On September 11, the United States decided to impose a punitive tariff for all cars and light truck tires imported from China for a period of three years. It will impose a 35% or 3% Ten and 25 percent special tariffs. According to previous analysis, the U.S. move will cause China's tires to no longer be exported to the United States. China will have about 30 or so tire companies cut production or suspend production, which will affect China's tire industry's output value of 2.2 billion U.S. dollars and will have 100,000 U.S. dollars. Tire worker employment is affected. Industry insiders worry that according to the WTO rules, other countries can directly invoke the US sanctions program to impose sanctions on Chinese exports of tires, which may lead other countries to follow suit and pose a more serious blow to the Chinese tire industry. Recently, India and Argentina have stated that they will conduct anti-dumping investigations on automobile tires originating in China with reference to the previous practice of the United States. If more countries follow the example, it will cause China's tire export environment to further deteriorate.
