End-to-end Quantity & Quality Control

The company operates a traceable quantity and quality system across sourcing, receipt, storage and dispatch. Source admission controls define indicators such as sulphur content and API grade, while every incoming and outgoing batch is sampled and tested before handling.

Dedicated staff follow each movement and retain composite samples for third-party verification by organisations including SGS and Hengruns inspection services. Stored products are tested for viscosity, flash point and other indicators; flow meters and weighbridges are calibrated regularly, and inventory records provide two-way quantity and quality traceability. The supplied company material reports a 100% annual product qualification rate.
