Beijing, June 17 (PTI): China has imposed an anti-dumping duty of up to 37.7 per cent on sulfamethoxazole, an antibiotic from India, to offset damages caused by cheap imports to the local producers.

This follows the final ruling made by China's Ministry of Commerce which said sulfamethoxazole exports from India have inflicted losses to local manufacturers.

The anti-dumping duty tax rates were increased from 10.7 per cent to 37.7 per cent and the tax would be in effect for five years.

Sulfamethoxazole is a sulfonamide bacteriostatic antibiotic and also serves as an important material in producing other sulfonamides. It is commonly used to treat urinary tract infections.

China started its anti-dumping investigation on imported sulfamethoxazole from India last June, and imposed temporary anti-dumping measures in February this year on the basis of its preliminary investigations.
