Quality Control

Our Zinc Carbonate Basic is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, heavy metal content, and physical properties. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing the results against agreed parameters. Production can be aligned with relevant industry standards, including USP, FCC, or technical grades, based on customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture and CO₂, which can affect product quality.
