Top 10 Companies in the Isophthalonitrile (INP) Market (2026): Market Leaders Powering Global Chemical Demand

MARKET INSIGHTS

Global Isophthalonitrile (INP) demand reached USD 490 million in 2025, with the market projected to rise to USD 520 million in 2026 and to approximately USD 900 million by 2034, reflecting a steady upward trajectory driven by polymer and agrochemical demand.

Isophthalonitrile (INP), or 1,3‑dicyanobenzene, is produced mainly through ammoxidation of meta‑xylene using oxygen and ammonia. The compound is indispensable for manufacturing m‑xylylenediamine (MXDA), a cornerstone intermediate for high‑performance polyamides, epoxy curing agents, and advanced coatings. The 99 % purity segment dominates, accounting for more than 95 % of applications due to stringent industrial specifications.

The market’s expansion is propelled by growing needs in coatings, adhesives, specialty polymers, and pesticide formulations. Japan leads production with a 65 % share, while China and the United States collectively account for 35 % of global consumption. Mitsubishi Gas Chemical, CAC Group, and Suli together hold an 85 % market share, underscoring the concentration of supply and the importance of vertical integration and catalyst innovation.
