Quality Control at Adde Technology
At Adde Technology, quality control is integrated into every stage of our production and supply process to ensure consistent product performance and safety. From raw material sourcing to final shipment, we apply rigorous inspection and documentation standards that meet the expectations of international customers.
Raw Material Inspection
All incoming raw materials are verified for identity, purity, and concentration using a standardized checklist. We work closely with trusted suppliers and maintain strict acceptance criteria to ensure batch consistency.

In-Process Control
During production, we closely monitor key variables such as temperature, pH, pressure, and reaction time to ensure the product develops within the expected parameters. Any deviations are recorded and addressed immediately.
Final Product Testing
Each finished batch undergoes strict quality testing, including:
pH level – to ensure product stability
Viscosity – to confirm physical consistency
Spectroscopic analysis – to verify chemical structure and purity
Test results are compared against product specifications before release.
Documentation & Traceability
All QC steps are fully documented and archived. We retain product samples and test reports for traceability, and can provide third-party lab testing (e.g., SGS) upon request. Regular internal audits ensure continuous improvement in quality and compliance.
