Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If normal potassium tartrate (di-potassium salt)
Fully neutralized tartrates classify as salts in 2918.13 per numerical order.
If treated as simple inorganic tartrate salt
Without organic classification priority, could go to inorganic sulfates chapter.
If preparations ready for baking powder use
Retail food preparations exclude from chapter 29.

Import Tips & Compliance
• Distinguish from full potassium tartrate (2918.13); partial neutralization keeps with acid
• FDA food contact notification if novel source; traditional wine-derived exempt
