China's Ministry of Commerce (MOC) announced Thursday it will adjust its anti-dumping duties on sulfamethoxazole (SMZ), an antibiotic imported from India, from Friday.

The MOC said it will impose anti-dumping duties of 17.2 percent on Andhra Organics Ltd. and Virchow Laboratories Ltd., and 36.4 percent on other Indian SMZ exporters.

The decision was made after the ministry finished its one-year mid-term examination, which showed that Indian SMZ exporters had not stopped their dumping activities in the country.

In 2007, the ministry put anti-dumping duties at between 10.1 percent and 37.7 percent on the import of SMZ from India.

The ministry launched the mid-term review on Aug. 17 last year after China's Shouguang Fukang Pharmaceutical Co. asked for an adjustment of tariff rates, as Indian SMZ producers increased their dumping efforts in China since the imposing of anti-dumping duties.
