Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified as nucleic acid salt instead of heterocyclic
Salts misidentified as nucleic acid derivatives fall under earlier 2934 nucleic acid provisions
If containing metal impurities exceeding organic compound criteria
High metal content shifts to inorganic salt classification in Chapter 28
If when imported diluted for azo dye production per Chapter 29 note 2(h)
Standard strength dilutions specifically for azo dyes move to Chapter 32

Import Tips & Compliance
• Include salt formation verification via NMR spectroscopy in documentation
• Check for water content as excessive hydration might affect classification purity requirements
• Confirm counterion is sodium only; other metal salts may require different subheadings
