Four Decades of Chemical Manufacturing Excellence
From our roots in Gujarat's industrial heartland to serving multinational corporations globally, Uma Dye Chem has stood for uncompromising purity, technical precision, and enduring client partnerships.
Pioneers in Ammonium Bisulphite & Sulfur Derivatives
Founded in 1984, Uma Dye Chem began with a clear purpose: to engineer high-purity inorganic sulfur chemicals manufactured right here in Gujarat to satisfy India's rapidly growing industrial sector.
Over forty years of continuous operation, we have mastered the delicate balance of gaseous ammonia and sulfur dioxide absorption chemistry. Today, we stand as one of India's leading producers of Ammonium Bisulphite Solutions across all standard assays (40%, 60%, 65%, 70%), dedicated Food Grade variants, and advanced catalyzed solutions (Nickel & Cobalt complexes) utilized in critical offshore oilfield operations.
Our manufacturing works are situated at Unava, near Unjha in Mehsana district—strategically connected to primary national highways and western India's mega container ports (Mundra, Kandla, and Pipavav) for expedited domestic transit and maritime exports.
