Products classified under HTS 2808.00.00.10
Concentrated Nitric Acid 68%
High-purity nitric acid with 68% concentration by weight, chemically defined as HNO3, used primarily in industrial nitration processes and metal etching. It falls under HTS 2808.00.0010 as a simple inorganic acid of nitrogen, explicitly covered in Chapter 28 for chemically pure compounds. This subheading distinguishes nitric acid from sulfonitric mixtures.
Fuming Nitric Acid 98%
Fuming nitric acid at 98% concentration, characterized by visible nitrogen dioxide fumes due to dissolved NO2, used in rocket propellants and organic synthesis. Classified under HTS 2808.00.0010 as pure nitric acid meeting Chapter 28 definitions for inorganic acids. The fuming property does not alter its chemical definition as HNO3.
Nitric Acid 70% Technical Grade
Technical-grade nitric acid at 70% HNO3 concentration for general industrial use like cleaning and passivation of stainless steel. It qualifies under HTS 2808.00.0010 as a chemically defined inorganic acid without organic stabilizers. Purity meets Chapter 28 Note 1 criteria despite 'technical' designation.
Red Fuming Nitric Acid (RFNA)
Red fuming nitric acid with 1-2% dissolved NO2, giving its characteristic red color, used in aerospace bipropellant fuels. Falls squarely under HTS 2808.00.0010 as chemically defined nitric acid per Chapter 28. High assay purity (>95% HNO3) confirms inorganic acid classification.
Nitric Acid 65% Semiconductor Grade
Ultra-pure nitric acid 65% HNO3 for wafer cleaning in semiconductor fabrication, with metal impurities <1 ppb. Classified in HTS 2808.00.0010 as it remains chemically defined HNO3 without excluded additives. High purity aligns with Chapter 28 requirements for inorganic acids.
Nitric Acid 90% Laboratory Reagent
ACS reagent-grade nitric acid 90% for analytical chemistry and lab research, meeting USP/NF standards. HTS 2808.00.0010 applies as a chemically pure inorganic acid without organic content. Bottled for laboratory use but retains pure compound status.
Nitric Acid 55% Industrial Cleaning Grade
55% nitric acid formulated for descaling boilers and cleaning stainless steel equipment in food processing plants. Despite industrial packaging, it qualifies for HTS 2808.00.0010 as chemically defined per Chapter 28 Note 1(a). No excluded organic stabilizers present.
