Anti dumping duty on hs 25231000

Hello!

My friend's company wants to import White Cement Clinker (HS Code - 25231000).

Is there any Anti-Dumping duty on the said product?

Also, is CVD the same as Anti-Dumping duty and is it (CVD) adjustable if he sells the product after processing it through his own excise registered plant?

Yours answers will be very much appreciated.

Best Regards,
