Organic standards are set by individual practitioners, traders and handlers, re-packers or individual producers of certain products who use them for internal purposes only, but few generally acceptable standards exist that are elaborated and approved at the national level through the wide participation of practitioners of the organic agriculture movement. This fragmentation and the related lack of any legal protection or quality signs make both certification and labelling impossible for most of these standards, according to IASA. Most of these certification bodies only provide certifications for the recently adopted basic national standards for the domestic market, which are different from those applied by foreign certification agencies. Certificates issued nationally by bodies lacking accreditation and on the basis of divergent domestic standards are of little use to companies willing to export on foreign markets.
