Commissioned research by advisory firm Eunomix Research has led the South African Chamber of Mines (CoM) to reject the third iteration of the United Nations Conference on Trade and Development (Unctad) report on trade misinvoicing, which it dismisses as poor analysis based on incorrect analytical methodologies and incomplete data, according to CoM chief economist Henk Langehoven. Eunomix Group CEO Claude Baissac noted in the Eunomix report that data-collection and commodity classification show critical discrepancies with the Unctad methodology. This reflects the findings in a CoM and Eunomix report published last year, which investigated the gold misinvoicing alleged by Unctad.
