Quality Control & Delivery

Batch-by-batch QC, a full compliance pack and flexible consolidated supply — removing procurement doubts with verifiable quality and stable delivery.

Incoming & outgoing QC

Key metrics tested batch by batch — surface area, oil absorption, particle size, pH, moisture, loss on ignition — with a COA shipped with the goods.

Full compliance pack

COA, SDS/MSDS, specs, use declarations and required test reports provided as a set — for your internal evaluation and import process.

Flexible supply

Small-batch, multi-grade, consolidated entry — from 25 kg for trials; stable repeat by line once validated.

From inquiry to repeat order
