The US Diphenylamine prices are expected to decline during June 2026 as weaker downstream demand, easing feedstock costs, and comfortable inventories weigh on prices. After firm gains in May, supported by higher Aniline costs, healthy tyre-sector demand, tight spot availability, and steady exports to Canada and Mexico, market momentum is projected to soften. The completion of pre-summer tyre production is likely to reduce purchases from rubber chemical, lubricant additive, and antioxidant sectors, while buyers rely on existing inventories. Falling Aniline and Benzene prices are expected to weaken cost support, despite stable crude oil values. With steady Gulf Coast production, balanced supply, competitive supplier offers, and limited export opportunities, Diphenylamine prices are forecast to remain under downward pressure throughout June.
