Himadri Speciality Chemical Ltd has started commercial operations of a new 70,000 MTPA Speciality Carbon Black production line at its Mahistikry facility in Hooghly, West Bengal. This brownfield expansion lifts the company's total Carbon Black manufacturing capacity to 2,50,000 MTPA, with speciality carbon black capacity at Mahistikry reaching 1,30,000 MTPA. With this scale, the Mahistikry site is now claimed to be the world's largest single-location speciality carbon black facility. The new line targets high-value applications across plastics, inks, paints, coatings, and other specialised segments. Management expects the new capacity to contribute meaningfully to revenue growth and strengthen the company's margin profile over the medium term.
This is a positive operational milestone that strengthens Himadri's leadership in speciality carbon black and supports future revenue and margin expansion. Short-term stock reaction may be muted unless the market sees clear evidence of strong capacity utilisation and demand uptake.
