Our Quality Assurance Journey
01
Mine-Head Audit
Every ton of raw graphite ore is chemically tested for Fixed Carbon (FC) at the mining site in Odisha before transport.
02
Micronization Control
During processing, we monitor Particle Size Distribution (PSD) using laser diffraction to meet client mesh requirements.
03
Batch Certification
Final products undergo a multi-stage lab purification check. A unique Certificate of Analysis (COA) is generated for every shipment.
