Prior information on changes to the SSS requirements of importing countries is essential to enable manufacturers to prepare their products for export. The SPS agreement requires that proposed changes to the sps requirements be notified to the WTO at a time when it is still possible to accept and amend the comments of trading partners before being adopted. An exception allows governments to immediately impose SPS measures in response to an emergency, but the emergency measure must be time-limited and feedback from trading partners must be taken into account when reviewing the temporary measure. The SPS Committee agreed on procedures and formats for transparency, which are subject to periodic review and revision during special sessions.6 The Tokyo Multilateral Trade Negotiations Round (1974-1979) negotiated an agreement on technical barriers to trade (the 1979 OTC Agreement or “Standardization Code”) (see note 2). Although not originally designed to regulate sanitary and plant health measures, the agreement covered technical requirements arising from food safety and plant health and plant health measures, including pesticide residue limits, inspection requirements and labelling. Governments that were members of the 1979 OBT agreement agreed to apply relevant international standards (for example. B those developed by the Food Safety Code), unless they felt that these standards would not adequately protect health. They also agreed to inform other governments, through the GATT secretariat, of technical regulations that are not based on international standards. The 1979 TBT agreement contained provisions for the settlement of commercial disputes arising from the application of food security and other technical restrictions. 1. Members ensure that their health or plant health measures are adapted to the sanitary or plant health characteristics of the area, whether it is a country, part of a country or, in whole or in part, several countries from which the product originates and for which the product is intended. In assessing the health or plant health characteristics of a region, members take into account, among other things, the prevalence of certain diseases or pests, the existence of eradication or control programs, and appropriate criteria or guidelines that can be developed by the relevant international organizations.
