Why Consistency Matters

A calcium carbonate shipment may appear visually acceptable while still differing in particle size, moisture, coating or chemical composition. These variations can affect production efficiency and final-product quality.

Quality control should therefore begin before loading and continue through packaging, storage and shipment documentation.

Common Quality Parameters

Chemical Purity

CaCO₃ content helps confirm the mineral’s chemical composition and suitability for the intended application.

Particle-Size Distribution

D50, D97 and top-cut measurements help manufacturers understand the complete particle profile.

Whiteness and Brightness

These properties are particularly important in paints, plastics, masterbatch and visually sensitive products.

Moisture

Controlled moisture supports storage stability and predictable processing.

Coating Verification

For coated grades, the presence and consistency of surface treatment should be assessed.

Packaging Condition

Bags must be clean, properly sealed and suitable for transportation and handling.

Test Reports and Traceability

A laboratory report should correspond to the relevant batch or shipment. Clear product identification and documentation improve traceability and help customers compare delivered material with agreed specifications.

CarboCore applies laboratory verification within its shipment-control process and provides relevant test documentation to support consistent export supply.
