In addition to Tah Hsin Industrial's Taiwan plants, the Tah Viet Plant (Ho Chi Minh City, Vietnam) and the Myanmar Tah Hsin Plant (Yangon, Myanmar) successfully passed ISO 9001:2015 Quality Management System third-party certification on July 24, 2025, and May 30, 2025, respectively.

As of now, a total of five Tah Hsin Industrial plants have passed ISO 9001:2015 Quality Management System third-party certification, holding four certificates in total. The certified plants are as follows:
1. Tah Hsin Taichung Plant
2. Tah Hsin Chung-Kan Plant
3. Tah Hsin DAFU Plant, China
4. Tah Hsin Tah Viet Plant, Vietnam
5. Tah Hsin Myanmar Plant, Myanmar

The certification scope of Tah Hsin Industrial covers rainwear manufacturing, rain boots manufacturing, laminator assembly, and PP corrugated board production.

Passing the ISO 9001:2015 Quality Management System third-party certification is only the starting point. The ultimate goal is for all employees to participate and be fully committed to quality management, to carry out their work with responsibility, and to recognize that their actions at every position are closely tied to product quality. This, in turn, fosters a sense of belonging and pride among employees toward the company's products.

At the same time, closely integrating the quality management system with daily workflows will also facilitate the implementation of other management standards in the future, such as ISO 27001 (Information Security Management) and ISO 45001 (Occupational Health and Safety Management). This will allow the company to continue growing and advancing. The purpose of introducing and establishing management systems is not to increase employees' workload, but to ensure that every aspect of the company's operations is safeguarded and effectively supervised.
