Quality Philosophy
At KNPZ, quality is not a department — it is the operating philosophy of the entire refinery. From the moment crude feedstock arrives at our gate to the moment certified product departs on a delivery tanker, every process step is governed by documented procedures, measurable parameters, and independent laboratory verification.
Our clients — whether a regional fuel distributor, a mining company, or a municipal infrastructure operator — need confidence that the product they purchase will perform exactly as specified in their equipment and processes. Delivering that confidence, consistently and verifiably, is the central obligation of our quality system.

Product Certification Process
Before any product batch is released for sale, the following certification steps are completed:
- Batch sampling at production stage and at product tank (composite sample)
- Full specification analysis by CAL against applicable GOST parameters
- Laboratory sign-off by qualified chemist with accredited certificate
- Product conformity certificate (Sertifikat Sootvetstviya) issued per applicable TR CU
- Dispatch documentation package: conformity certificate, quality passport, and delivery note provided to buyer for each shipment
