The Chinese Commerce 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, state-run Xinhua news agency reported.
In 2009, the ministry had extended the anti-dumping duties on phthalic anhydride imports from these three countries, extending it for another five years after a review investigation, saying such imports would cause damage to Chinese industries.
Phthalic anhydride is an important industrial chemical mainly used in the mass production of plasticizer for plastics.
