Food grade magnesium carbonate is a basic hydrated magnesium carbonate material used in suitable formulations as an anticaking, flour-treatment or mineral ingredient.
Share the intended food, target limits, test methods, quantity and destination.

Product overview
Food grade magnesium carbonate is a light or heavy white magnesium carbonate material. The commercial reference describes a basic hydrated composition and 40.0–43.5% MgO, while Codex identifies magnesium carbonate as INS 504(i).
Commercial suitability depends on the exact grade, source, test method, application and destination-market rules. The current signed specification and batch COA govern a transaction.
Application screening
Select permitted food applications and evaluate dosage and performance in the finished product.
Evaluate flow, anticaking performance and the legal use level in the finished food.
Evaluate flour-treatment use against destination-market authorization and finished-product performance.
Match magnesium contribution, purity and bioavailability requirements to the finished product.
Specify light or heavy bulk density, particle behavior and moisture controls.
Commercial specifications
These commercial reference specifications are separate from batch COA results and regulatory requirements. Agree the grade, analytical basis and test methods for your order.

Specification and identity note: The commercial identity is CAS 583678-75-4 with a variable basic-hydrate formula; the FAO/JECFA magnesium carbonate record lists CAS 546-93-0 and INS 504(i). These identifiers are not interchangeable evidence of conformity. Match the offered composition and CAS across the signed specification, SDS and COA.
