According to the Ministry of Commerce website, since November 21, 2009, the import of toluene diisocyanate from Japan, South Korea, and the United States has continued to implement anti-dumping measures with an implementation period of five years.

The Ministry of Commerce believes that if anti-dumping measures are terminated, the dumping of imported toluene diisocyanate originating in Japan, South Korea, and the United States may continue, and damage to China's domestic industry may recur.

The product is toluene diisocyanate (Model TDI80/20), and is assigned to the "Import and Export Tariff of the People's Republic of China" tariff code. The English name of the product is Toluene Diisocyanate.
