December 30th News: Cabot Corporation's carbon black plant expansion in Cilegon, Indonesia (adding 80,000 tons/year) was completed by the end of 2025, with a total investment of approximately $100 million. The capacity has nearly doubled, strengthening local supply and delivery efficiency in Southeast Asia and consolidating its leading position in the region. Chempricehub's analysis of carbon black, with a bullish-bearish score of -1: Cabot's Indonesian plant expansion, adding 80,000 tons/year of capacity, was completed by the end of 2025, nearly doubling its capacity and significantly increasing market supply. The rise in supply may lead to an oversupply of carbon black spot in Southeast Asia, putting downward pressure on prices. At the same time, strengthening local supply and delivery efficiency reduces logistics costs, further depressing spot prices. Although this move consolidates Cabot's leading position in the region, the short-term supply expansion dominates the bearish impact, and carbon black spot prices are expected to face downward pressure.
