AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Both are classified under 2835220000, but they differ in pH and functional properties: monosodium phosphate is more acidic and used as a buffering agent, while disodium phosphate is mildly alkaline and commonly used as an emulsifying salt in processed cheese and as a sequestrant. Buyers should specify which form is required in purchase contracts, as suppliers may ship either unless the grade is explicitly stated.
Yes. Food-grade mono- and disodium phosphates are subject to FDA oversight as food additives. Importers should be prepared to provide certificates of analysis, manufacturer information, and prior notice of food import as required by FDA regulations.
