Potassium Gluconate Food Additive Grade, CAS 299-27-4
Potassium gluconate is a potassium salt used by food, beverage, nutrition, and supplement manufacturers where a water-soluble mineral salt additive is required. Buyer checks should focus on CAS 299-27-4 identity, assay basis, food-grade compliance documents, heavy metal and microbiological limits, particle appearance, solubility, and export-ready packaging documentation.

For sea freight or air freight, confirm packaging is suitable for food additive export and protected against moisture ingress
Ask whether private label, neutral label, or buyer-specified label formats are available for compliant markets
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.

How we compare
Sourcing options
1 kg foil bag sample or trial pack, subject to supplier confirmation
25 kg drum standard export pack
Buyer-specified label or neutral export packaging, subject to compliance review
Batch-specific COA shipment with pre-shipment document review
Request quotes by grade standard, assay, packaging format, destination port, and annual volume
Human review
Compliance notes
Request current COA by batch before shipment
Request SDS, TDS/specification sheet, food-grade statement, allergen statement, non-GMO statement, BSE/TSE statement, and country-of-origin certificate if required
For food or supplement use, buyer should verify conformity with destination-market rules before purchase
Confirm whether the offered material complies with FCC, USP, EP, GB, or other required monograph/specification standards; do not rely on title claims alone
Confirm HS code, export license status if applicable, and DG classification for the planned route; potassium gluconate is typically not positioned as dangerous goods, but shipment documents should state the supplier classification
Check labeling requirements for mineral additives in the buyer's market, including permitted use category and declaration format
Supplier platform claims and audit badges should be treated as commercial references, not regulatory approvals
