• Introduction to WTO rules on technical barriers to trade and understanding of the TBT Although the TBT Agreement applies to a wide range of industrial and agricultural products, sanitary and phytosanitary measures and specifications for government procurement are the subject of separate agreements. OEE rules help distinguish between legitimate standards and technical rules and protectionist measures. Standards, technical rules and conformity assessment procedures must be developed and applied in a non-discriminatory manner, developed and applied in a transparent manner and, where appropriate, based on relevant international standards and guidelines. 6.3 Members are encouraged to be prepared, at the request of other members, to enter into negotiations with a view to concluding agreements on the mutual recognition of the results of each other`s conformity assessment procedures. Citizens of the parties to the dispute may not work in a technical group of experts without the common agreement of the parties to the dispute, unless, in exceptional cases, the body considers that the need for specialized scientific expertise cannot be met in any other way. Government officials of the parties to the dispute may not call upon a technical panel of experts. Members of technical expert panels are in their individual capacity and are not representatives of the government or representatives of any organization. Governments or organizations cannot therefore give them instructions on matters before a technical group of experts. The TBT aims to ensure that technical regulations, standards, testing and certification procedures do not create unnecessary barriers to trade. . .
