It has been a giant leap forward when the GCC Standardization Organization (GSO) has decided to implement the RCAS project in November 2005. Such enormous step by GSO aims at advancing the Gulf Cooperation Council (GCC) goals through the harmonization, integration and building of the standardization areas and quality infrastructure in the Member States. RCAS stands for the initials of “Regional Conformity Assessment Scheme”. The project has been planned to focus on the current procedures and practices to verify the conformity of the imported or the exported local produced products. The outcomes of the project have evolved to comprise developing scheme to enhance such practices in the context of a harmonized unified regional system.

The target of the system should be serving the national and regional interests of GCC member states, so as to streamline the commercial activities of members inter alia and with other countries and regions as well.
