BEIJING, Aug. 29 (Xinhua) -- The Chinese mainland is to levy five-year anti-dumping duties from Aug. 30 on BPA (Bisphenol-A) imported from Japan, Singapore, Republic of Korea, and Taiwan, said the Ministry of Commerce on Wednesday.

Importers of BPA, a type of organic chemical mainly used in producing antiseptic and paint, would have to pay a 5 to 37.1-percent duty to offset damage caused by BPA producers in the above countries and regions, said the ministry.

This followed the final conclusion reached by the Ministry of Commerce that BPA from these countries and regions had constituteddumping and inflicted losses to local manufacturers.

According to the initial conclusion publicized by the ministry on March 21 this year, the foreign exporters and manufacturers accused of dumping include Mitsui Chemicals,Inc, UMHO P&B Chemicals,Inc, MITSUI PHENOLS SINGAPORE PTE,LTD, and the Na Ya Plastics Corporation.

China started the anti-dumping investigation into imported BPA on Aug. 30 last year.
