This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing ammonia derivatives
Anhydride or oxide forms with ammonia shift to 2814; nitric acid remains distinct unless complexed per notes.
If organic nitro compound
Organic derivatives like nitroalkanes fall in Chapter 29, excluded from Chapter 28 per general rules.
If supported catalyst
Supported catalysts with nitric acid impregnated on carriers classify in 3815, not pure acids.

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.
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.
