TBHQ is used as an antioxidant in cooking oil and as additives in pharmaceutical and animal feed products. Phthalic anhydride is an important industrial chemical mainly used in mass production of plasticizer for plastics.
China’s commerce ministry’s final ruling came four months after it launched temporary anti-dumping measures against such imports from India, state-run Xinhua news agency reported.
According to the ministry’s year-long investigation, such imports have caused substantial damage to China’s domestic industry.
Earlier, the ministry said it would stop imposing anti-dumping duties on phthalic anhydride imported from the India, South Korea and Japan and India starting August 30.
The ministry said it has received no expiry review request from Chinese industries to extend the anti-dumping duties that will expire on August 30 and it won’t start an expiry review itself, Xinhua reported.
In 2009, the ministry extended the anti-dumping duties on phthalic anhydride imports from the three countries for five years after a review investigation, saying such imports would damage Chinese industries.
