The Finance Ministry has extended the validity of existing anti-dumping duty on certain rubber chemicals from China and South Korea by one year.

The anti-dumping duty on rubber chemicals MBT, CBS, TDQ, PVI, and TMT imported from China will remain in force till May 4 next year, the Revenue Department has said.

For PX-13 (6PPD) imports from South Korea, the existing anti-dumping duty will also be continued till May 4, 2014.

These chemicals are used in treating natural rubber and synthetic rubber-based compounds.

The Revenue Department move follows the initiation of sunset review investigation on these rubber chemicals by the designated authority in the Commerce Ministry.

National Organic Chemical Industries Ltd (NOCIL), Mumbai had filed the petition seeking sunset review, it is learnt.
