A food-grade evidence enquiry should establish the actual offered magnesium carbonate specification and intended use requirements. This material is identified as MgCO3, white in appearance, with reported 99% purity; those descriptors do not establish food-use approval.
Request the actual magnesium carbonate grade documents
Obtain current analysis, technical and safety records defining composition, assay basis and relevant impurity limits. Ask for the applicable food-grade specification and qualification evidence for the actual proposed use rather than treating a title label as approval.
- Grade question
- Which actual specification applies to the material being offered?
- Form question
- What powder, light/dense or granule characteristics are required and measured?
- Use question
- Which applicable qualification and representative acceptance evidence support the proposed application?
Confirm physical criteria for the actual offered form
Density is reported as 2.958 g/cm3, with its applicable method to confirm. Clarify the physical-form criteria and relevant water-solubility conditions; decomposition wording is not an ordinary melting-point criterion or an operating setting.
Keep grade labels separate from actual use acceptance
Industrial and reagent labels also require a defined offered specification and do not establish verified reagent qualification. Evaluate the confirmed composition and physical criteria against the actual end-use requirements without inferring suitability from purity alone.
Reconcile chemical identifiers with matched current records and obtain the actual grade and qualification information required by the project. Select the offered carbonate only after its form, analytical basis and representative acceptance evidence meet the specific use requirements being assessed.
