The Agreement on Technical Barriers to Trade (TBT)

The TBT Agreement of the World Trade Organization (WTO) aims to ensure that technical regulations, standards, and conformity assessment procedures are non-discriminatory and do not create unnecessary obstacles to trade. At the same time, it recognises WTO members' right to implement measures to achieve legitimate policy objectives, such as the protection of human health and safety, or protection of the environment. The TBT Agreement strongly encourages members to base their measures on international standards as a means to facilitate trade. Through its transparency provisions, it also aims to create a predictable trading environment.

Annex 3 of the TBT Agreement is the Code of Good Practice for the Preparation, Adoption and Application of Standards, also known as the TBT Code of Good Practice. WTO Members are required to ensure that their central governmental standardizing bodies accept and comply with this Code of Good Practice and take reasonable measures to ensure that local government, non-governmental and regional standardizing bodies also accept and comply. The Code contains a number of standards-related notification requirements, namely regarding the acceptance of (or withdrawal from) the Code and the publication/availability of work programmes.
