The Belarusian State Committee for Standardization (BELST) is Belarus's national body for standardization, metrology, and conformity assessment, playing a crucial role in developing and promoting standards to ensure quality, safety, and interoperability across various sectors. Established as part of the State Committee for Standardization, BELST operates under the aegis of the Ministry of Economy. Its mission includes formulating national standards, conducting metrology, overseeing conformity assessment activities, and promoting best practices to support industry, public welfare, and environmental sustainability in Belarus.

BELST collaborates with both national and international organizations to align Belarusian standards with global best practices. It is an active member of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). Through its involvement with regional bodies such as the Euro-Asian Council for Standardization, Metrology and Certification (EASC), BELST helps harmonize standards within the Eurasian region and promotes their global adoption. This collaboration supports the integration of Belarusian standards into the international framework and enhances the competitiveness of Belarusian products and services in global markets.

There is a organization simmilar to BELST: Belarusian State Institute of Standardization and Certification (BelGISS).

But there is a difference between the two organizations:

1. Belarusian State Institute of Standardization and Certification (BelGISS):
Role: BelGISS is primarily focused on the development, implementation, and certification of standards within Belarus. It acts as the technical body responsible for ensuring that products and services meet specific standards and requirements. This includes activities like testing, certification, and providing expert opinions.
Function: BelGISS is more technical in nature and deals directly with the practical aspects of standardization, such as certification of products, services, and management systems. It plays a critical role in conformity assessment procedures and in the accreditation of testing laboratories.

2. Belarusian State Committee for Standardization (BELST):
Role: BELST is the governmental authority responsible for overseeing the entire standardization system in Belarus. It is involved in policy-making, regulatory oversight, and the coordination of standardization activities across various sectors.
Function: BELST operates at a higher level, establishing national policies and regulations related to standardization, metrology, and quality management. It sets the strategic direction for standardization in Belarus and oversees the work of organizations like BelGISS.

In summary, BelGISS handles the technical implementation and certification aspects, while BELST focuses on the broader regulatory and policy framework for standardization in Belarus.
