Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If blended with >10% other chelating agents or surfactants
Mixtures of chemicals not chemically defined fall under Chapter 38 prepared binders; chapter note prioritizes pure compounds in 29.
If for agricultural use as plant growth regulator in fertilizers
End-use in fertilizers shifts to Chapter 31; pure chemical remains in 29 unless specifically prepared for ag application.
If sold as aqueous solution >50% concentration
Chapter notes allow solutions only if normal for safety/transport; high-concentration solutions may classify as salts of inorganic acids.

Import Tips & Compliance
• Verify purity certificate showing >98% sodium gluconate content to confirm classification under 2918.16.50.10 vs mixtures
• Include chemical analysis report and CAS number (527-07-1) in documentation for CBP review
• Avoid misclassification as food additive; technical grade requires industrial end-use declaration
