Quality & Certifications
Enforcing rigorous quality control procedures and holding leading global safety certificates is central to KLC's manufacturing philosophy.
Holding Global Trust Standards
We align our manufacturing plants with international management frameworks, securing credentials across quality, environmental responsibility, safety, and hygiene.

ISO 9001:2015
Ensures products meet client requirements with consistent quality.

ISO 14001:2015
Commits to eco-friendly production and environmental standards.

OHSAS 45001
Secures a safe, healthy workplace and prevents work-related injury.

FSSC 22000
Certified standards for food-grade Calcium Carbonate processing.

WHO-GMP
Ensures products are consistently controlled to quality standards.

FSSAI
Registered and compliant with Indian food safety guidelines.
Our 6-Step Quality Control Protocol
Batch consistency is maintained by executing testing checks at each step of the calcite and chemical carbonation process.
Raw Material Sourcing Purity
Limestone feedstock and calcite raw mineral are sourced from premium high-purity calcite quarries and verified for calcium carbonate assay and minimal acid-insoluble impurities before processing.
Reactor Carbonation Sizing
During precipitation, carbon dioxide gas and hydration ratios are monitored. This allows reactors to control the crystal habit (forming uniform aragonite patterns) and initial particle width.
Classification & Sieve Residue Checks
For both GCC and PCC, materials undergo automated air classification. We verify sieve residue (checking that 99.5% - 99.9% passes through a 325 mesh / 45 µm sieve) to prevent grit problems.
Microbial Testing (Pharma/Food Grades)
For KLC-101 grade, we test for total bacterial counts and yeast/mold parameters in clean lab rooms, enforcing standards under WHO-GMP and FSSC 22000 specifications.
Laser Particle Diffraction
We analyze d50 (medium diameter) and d97 top-cut using laser particle size analyzers. This ensures consistency and prevents formulation drift for plastics and coatings.
Retention Samples & Traceability
Every shipped batch is stamped with a unique batch serial number. We retain physical verification samples and laboratory test records for 12 months to ensure traceability.
