Carbon black (pigment grade, N990/N330)

World's largest carbon black producer by volume (~11-12% global share, 2.13 Mt/yr capacity). 19 plants in 14 countries. Part of Aditya Birla Group -- the same conglomerate that owns Novelis (world's largest aluminum flat-rolled producer) and Hindalco. This means a single Indian family-controlled conglomerate controls the world's largest aluminum sheet rolling company AND the world's largest carbon black producer -- two critical tire manufacturing inputs.

One of the world's three largest carbon black producers; tire-grade carbon black (Specialty Fluids, Reinforcement Materials segment) accounts for ~70% of Cabot revenue; operates plants across the Americas, Europe, and Asia supplying all major tire manufacturers.

China's largest single domestic carbon black producer (~6% global share, 1.14 Mt/yr). Shenzhen A-share listed. Produces N-series rubber-grade carbon black primarily for Chinese tire manufacturers. Uses coal-tar-derived feedstock (CBFS from coke-oven operations). Coal-tar CBFS gives different PAH surface chemistry vs. petroleum-based CBFS from Western producers.

NYSE-listed specialty carbon black producer; ~7% global share (1.37 Mt/yr). 15 plants on 3 continents. Operates world's longest-running carbon black plant at Kalscheuren/Cologne, Germany (est. ~1860s). Produces both rubber-grade (tire) and specialty-grade (ink, coatings, electronics) carbon black. 2024 10-K flagged structural demand headwind: elevated Chinese tire imports into North America and Europe displacing commodity CB demand.

Major Japanese carbon black producer (~5% global share, ~0.94 Mt/yr); also produces graphite electrodes, silicon carbide, and fine carbon products. 7 Japanese carbon black plants + international operations (Thailand, Canada, US). Cancarb subsidiary (Medicine Hat, Alberta) is the world's primary thermal black producer -- a distinct carbon black type used in specialty applications.
