AdvanSix Inc. is an integrated chemistry company that produces essential materials for diverse end markets. The company operates five US based manufacturing facilities that support a value chain converting raw materials into products such as nylon resin, caprolactam, ammonium sulfate fertilizer, and various chemical intermediates. Its products serve industries including building and construction, fertilizers, agrochemicals, plastics, solvents, packaging, paints, coatings, adhesives, electronics and others.

AdvanSix generates revenue primarily through the sale of its three product families: Nylon Solutions, Plant Nutrients, and Chemical Intermediates. Nylon Solutions include Nylon 6 resin sold under the Aegis® brand and caprolactam, the key monomer for nylon production. Plant Nutrients consist mainly of ammonium sulfate fertilizer marketed under the Sulf‑N® brand, along with co‑products such as sulfuric acid, ammonia and carbon dioxide. Chemical Intermediates comprise acetone, phenol, alpha methylstyrene, cyclohexanone, oximes, cyclohexanol and various amines. The company sells these products to a broad base of industrial, agricultural and commercial customers, primarily in the United States but also with global reach.

The company operates through the following segment.

• Integrated Chemistry Segment: This segment encompasses the company's integrated chemistry operations, including the production of nylon solutions, plant nutrients, and chemical intermediates, leveraging its vertically integrated manufacturing footprint to serve diverse end markets.

AdvanSix holds a strong position as one of the world's lowest cost producers of caprolactam and ammonium sulfate, benefiting from its integrated manufacturing footprint, large scale, favorable U. S. location and high plant utilization rates. Its competitive advantages include vertical integration into key feedstocks such as phenol, ammonia and sulfuric acid, access to low cost natural gas, and long term customer contracts that support steady plant utilization. The company faces competition from integrated nylon producers such as BASF Corporation, UBE Corporation, DOMO Chemicals GmbH, Envalior, Highsun Group Holdings Ltd., and Sinopec Limited; from ammonium sulfate producers like Pasadena Commodities International and Nutrien Ltd.; and from stand alone phenol and acetone makers such as INEOS Phenol, Altivia, and Eastman Chemical Company for its amine line.

AdvanSix serves approximately 375 customers annually, with the majority located in the United States and global capabilities across multiple industries. Its largest customer is Shaw Industries Group Inc., which accounts for about 10% of total sales, while the ten largest customers together represent roughly 40% of revenue. The customer base spans automotive manufacturers, construction firms, agricultural distributors, packaging companies, and makers of paints, coatings, adhesives and electronic components.
