A dietary supplement manufacturing factory certified by SGS.
In the dietary supplement industry, certification from internationally recognized inspection bodies serves as a crucial “quality assurance” guarantee. One of the most stringent and globally accepted standards is SGS (Société Générale de Surveillance), an organization with a long history dating back to 1878 and headquartered in Geneva, Switzerland.
Maydi International Co., Ltd., as a full-service dietary supplement manufacturer, has successfully passed the SGS audit and certification an achievement that only a few factories in Thailand are able to obtain.

What is SGS, and why is it important?
SGS is a world-leading organization in inspection, testing, and certification, particularly within the food and dietary supplement industries. SGS conducts assessments starting from:
- Quality and safety of raw materials
- Every step of the manufacturing process
- Quality control throughout the production line
- All the way to finished product testing
SGS inspections are renowned for being rigorous, detailed, and comprehensive across all dimensions. Not every factory can pass, as they must demonstrate compliance in documentation, management systems, and actual practices on the production line.
The difficulty of obtaining SGS certification
The factors that make obtaining SGS certification challenging are:
- A quality management system that complies with international standards must be in place.
- ll employees at every level must understand and adhere to the same standards.
- The manufacturing processes must be controlled and documented in detail.
- Products must undergo continuous quality inspection.
Therefore, being certified by SGS is not just a “one-time inspection,” but a proof of sustainable management practices and manufacturing excellence.
