Under the notification, anti-dumping duties ranging from US$75 per metric tonne to US$1,748 per metric tonne have been imposed, depending on the country of origin and the producer. The levy will remain in force for five years unless revoked or amended earlier.

The decision is expected to benefit domestic manufacturers led by NOCIL, India's largest rubber chemicals producer. NOCIL manufactures Sulphenamides Accelerators under its Pilcure brand, a product widely used in the vulcanisation process that enhances the strength, durability and performance of tyres and other rubber products.

NOCIL, a part of the Arvind Mafatlal Group, is the largest manufacturer of rubber chemicals in India. With a presence in more than 40 countries, NOCIL serves a diverse range of sectors, including tire, automotive, rubber goods and various industrial applications.

The specialty chemical maker’s consolidated net profit dropped 18.22% to Rs 17 crore on 2.74% decrease in net revenue from operations to Rs 330.35 crore in Q4 FY26 over Q4 FY25.
