Products classified under HTS 2808.00.00
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.
Red Fuming Nitric Acid (RFNA)
Red fuming nitric acid with >6% dissolved NO2, used in bipropellant rocket fuels. Remains under HTS 2808.00.00 as nitric acid variant, chemically defined.
White Fuming Nitric Acid (WFNA)
Colorless white fuming nitric acid >97% purity for precision etching. HTS 2808.00.00 as pure nitric acid.
Dilute Nitric Acid 10% Solution
10% aqueous nitric acid for pH adjustment and cleaning. Still HTS 2808.00.00 if chemically defined nitric acid.
High-Test Peroxide Nitric Acid Blend
Specialty sulfonitric variant with peroxide for advanced nitration. HTS 2808.00.00 as sulfonitric acid.
Electropolishing Nitric Acid 50%
50% nitric acid formulated for stainless steel electropolishing. Pure acid base keeps it in HTS 2808.00.00.
Azeotropic Nitric Acid 68.5%
Constant-boiling 68.5% nitric acid for lab standards. HTS 2808.00.00.
