Quality Control
At Ascent Petrochem Holdings Co., Limited, rigorous quality control runs through the entire methylene chloride production workflow. Starting from raw material incoming inspection, every production batch undergoes systematic monitoring, intermediate sampling testing and finished‑product verification in our in‑house laboratory. We enforce strict batch‑by‑batch quality checks to guarantee stable purity, low impurity levels and consistent product performance for industrial, pharma‑grade, food‑grade and reagent‑grade DCM. Each shipment is accompanied by complete COA test reports, helping global customers mitigate quality‑related risks.
