Nitric Acid 68% Concentration
Nitric acid at 68% concentration by weight is a highly corrosive, fuming liquid used primarily in the production of fertilizers, explosives, and metal etching. It falls under HTS 2808.00.00 as a chemically pure inorganic acid, specifically nitric acid (HNO3), distinct from organic derivatives or mixtures excluded by Chapter 28 notes.
Fuming Nitric Acid 98%
Fuming nitric acid at 98% concentration contains dissolved nitrogen oxides, appearing red or white, used in organic synthesis and rocket propellants. Classified under HTS 2808.00.00 as nitric acid meeting Chapter 28 Note 1 purity standards, not as a complex mixture.
Sulfonitric Acid Mixture
Sulfonitric acid is a freshly prepared mixture of concentrated nitric and sulfuric acids used for nitration in explosives and dyes. It qualifies under HTS 2808.00.00 explicitly as 'sulfonitric acids,' treated as a defined inorganic acid blend per the heading.
Laboratory Grade Nitric Acid 70%
Purified nitric acid at 70% for analytical and lab use, trace metal free. Falls under HTS 2808.00.00 as chemically defined nitric acid for inorganic compounds per Chapter 28 Note 1.
Technical Grade Nitric Acid 65%
Industrial technical nitric acid 65% for metal cleaning and fertilizer production. HTS 2808.00.00 covers this as standard nitric acid, excluding fertilizer mixtures in Chapter 31.
