Members should report this when two conditions apply: 1) if there is no relevant international standard or guidance or recommendation, or if the technical content of a proposed or adopted technical regulation or procedure is not consistent with the technical content of the relevant international standards or guidelines of the recommendations; and (2) where technical regulation or compliance assessment procedures can have a significant impact on other members` exchanges (Articles 2.9 and 5.6). Draft regulations should be communicated to the WTO secretariat 60 days before their formal adoption, if possible, so that other members have time to comment. Requirements can also be notified in case of urgent safety, health and environmental issues (Articles 2.10 and 5.7). Local authorities located just below the central government are required to notify technical rules and compliance assessment procedures that have not been previously notified by their central authorities (Articles 3.2 and 7.2). As explained in the previous section, proof of compliance with technical rules can impede international trade. If products are to be exported to multiple markets, several tests may be required. Manufacturers may have difficulty obtaining approval of their products in foreign markets, for example because test experts disagree on optimal testing methods, bureaucratic inertia or even by manipulating the testing process by protectionist groups. Whatever the reason, such a variety of procedures and methods significantly increases the costs of producers selling in multiple markets. 2.4 Where technical requirements are required and relevant international standards exist or are in the process of being completed, members use them or their relevant parties as the basis of their technical regulations, unless these relevant international standards or parties are an ineffective or inappropriate means of achieving legitimate objectives, for example due to fundamental climatic or geographic factors or fundamental technological problems. Noting that developing countries face particular difficulties in developing and enforcing regulations and technical standards and procedures for assessing compliance with technical regulations and standards, and willing to assist them in their efforts to do so; In recent years, the number of regulations and technical standards adopted by countries has increased considerably. A strengthened regulatory policy can be seen as the result of a higher global standard of living, which has increased consumer demand for safe and quality products, and increasing problems of water, air and soil pollution, which modern societies have encouraged to explore environmentally friendly products. 12.8 It is recognized that members of developing countries may face particular problems, including institutional and infrastructure, in the preparation and enforcement of technical regulations, standards and compliance assessment procedures.
