The anti-dumping duty of 49.8% on the TBHQ imports will begin on Friday and last five years, said the chinese commerce ministry. TBHQ can be used as antioxidant in cooking oil or as additives in the pharmaceutical and animal feed industries.
The commerce ministry's 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, TBHQ imports from India have been dumped in the Chinese market and such imports have caused substantial damage to China's domestic industry.
However, the anti-dumping duties will not be retroactive to imports before. Earlier the ministry had said it will stop imposing anti-dumping duties on phthalic anhydride imported from India, South Korea and Japan from August 30.
The ministry said it has received no expiry review request from the 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.
Phthalic anhydride is an important industrial chemical mainly used in the mass production of plasticizer for plastics.
