Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If technical grade with significant impurities
High impurities may push to 'other' if not meeting chemically defined compound criteria.
If used in azo dye coupler production
Diazonium couplers diluted for azo dyes classify under Chapter note (h) mixtures, not pure compounds.
If sold as dye intermediate mixture
Industrial dye intermediates often mixtures (3824) vs pure Chapter 29 compounds.

Import Tips & Compliance
• Declare impurities (<2% typically isomers/salts) but ensure principal compound is gentisic acid via GC-MS
• Bulk drums >25kg avoid retail classification; include MSDS with GHS hazard pictograms
• Confirm no anti-dusting agents added that render suitable for specific use per Chapter note (g)
