Quality Control

We implement strict quality control procedures for every batch of plasticizers before shipment. Each lot undergoes laboratory testing covering key indicators including purity, moisture, viscosity and acid value. We inspect product certificates and verify compliance with international standards, ensuring all delivered goods match the agreed specifications and meet global regulatory requirements.
