Quality & Certifications
Certified Quality. Tested at Every Stage.
Every batch of mineral leaving our Parbatsar plant is tested in-house across 9 parameters before dispatch. Quality is not an afterthought — it is built into our process.

In-House Laboratory
Tested Before Every Dispatch
Our in-house quality lab is equipped with dedicated instruments for brightness, whiteness, bulk density, and sieve analysis — ensuring every batch meets specification before it leaves the plant.
Testing Parameters
9 Parameters. Every Batch.
Our in-house lab tests every finished batch across all parameters before dispatch. A Certificate of Analysis is issued with each shipment.
Brightness
ISO 2469 / Elrepho
Measures diffuse reflectance — critical for paper, paint, and coating applications.
Whiteness
CIE Whiteness Index
Indicates visual whiteness — key for premium coatings and consumer products.
CaCO₃ Content
EDTA Titration
Confirms calcium carbonate purity — critical for pharma and food-grade applications.
Moisture Content
Loss on Drying (105°C)
Ensures product stability during storage and transport.
Bulk Density
Standard Funnel Method
Important for packaging, dosing, and process equipment design.
Oil Absorption
ASTM D281
Determines binder demand in paint and coating formulations.
Mesh Residue / Particle Size
Sieve Analysis
Confirms particle size distribution to specification.
Acid Insoluble (SiO₂)
Gravimetric Analysis
Measures silica and insoluble impurities — critical for rubber and plastics.
AIM Test
Internal Method
Acid insoluble matter test for quality assurance.
In-House Equipment
Our Testing Infrastructure
Bulk Density Machine
Measures apparent and tapped bulk density of powder products
Brightness Machine
Measures ISO brightness (diffuse reflectance) per ISO 2469 standard
Whiteness Machine
Measures CIE whiteness index for visual whiteness assessment
Our Process
Quality at Every Stage
Raw Material Inspection
Incoming limestone and marble are sampled and tested for CaCO₃ content and impurity levels before entering production.
Processing & Grinding
Material is processed through our grinding and classification lines to achieve the specified mesh size and particle distribution.
In-Process Quality Checks
Samples are drawn at multiple stages during processing and tested for brightness, whiteness, and particle size.
Final Batch Testing
Every finished batch is tested across all 9 parameters. A Certificate of Analysis (COA) is issued with each shipment.
Packaging & Dispatch
Approved batches are packed in 25 kg, 50 kg, or jumbo bags and dispatched with full documentation.
