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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If concentration is under 68% by weight
HTS splits nitric acid by concentration threshold; lower strengths fall into the secondary subheading for diluted forms.
If mixed with other substances or additives for specific end-use
Mixtures of nitric acid with organic/inorganic compounds lose 'chemically defined' status per Chapter 28 Note 1, shifting to chemical preparations in Chapter 38.
If formulated as urea nitrate fertilizer
Chapter 31 Note excludes certain nitrogen compounds used as fertilizers from Chapter 28, classifying them as mineral/chemical fertilizers.

Import Tips & Compliance
• Verify concentration and purity via Certificate of Analysis to confirm classification under 2808; ensure proper UN 2031 hazmat labeling and shipping papers for corrosive class 8 goods; avoid misdeclaration as diluted solutions which may shift to 2808.00.0020
