Chinese importers of sulfamethoxazole will have to pay anti-dumping duties as of June 16 to offset damages caused by sulfamethoxazole producers in India.

The move follows the final ruling made by the Ministry of Commerce which said sulfamethoxazole exports from India have inflicted losses to local manufacturers.

The anti-dumping duty tax rates were set from 10.7 to 37.7 percent, 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.
