Maintaining quality standards with above-standard practices

Dec 18, 2025

Our raw material supply system is based on the core principles of compliance, traceability, and stability. All our partner suppliers possess relevant national production certifications and have passed our company's annual supplier assessment, covering three key dimensions: production capacity, quality control, and environmental compliance. Every batch of raw materials supplied comes with a material testing report, RoHS environmental certification, and batch traceability documentation. From the final output of petrochemical refining to the inspection and acceptance at our factory warehouse, all information is verifiable and traceable, preventing the influx of unqualified and untraceable materials.
