Creating a brighter future through continuous technical innovations

Since the commencement of manufacturing nitric acid in 1991, Hanwha has reliably supplied the industry's highest-quality nitric
acid to the nation's largest customers through numerous mid- to long-term supply contracts, while steadily increasing
the volume of our exports to Japan, Taiwan, and Southeast Asian countries. By delivering a steady supply of price-competitive,
high-quality liquid ammonium nitrate, a key ingredient of industrial explosives, Hanwha Corporation has contributed significantly
to the nation's industrial development. Our liquid ammonium nitrate is also used in the productionof medical gases and for
semiconductor processes at home and abroad. In addition, we import and supply ammonia not only to customers in the fields
of bio-food technology and high-purity industrial gas production but also to the De-NOx facilities of major thermal power plants
in the nation, helping reduce NOx emissions and improve air quality.
