CertiSource certifies supply chain entities such as forest concessions and manufacturing sawmills, but also each batch of timber traded. Audits of timber legality are carried out by an independent, accredited Certification Body (CB) against CLAS - the ‘CertiSource Legality Assessment System’ which consists of the Certisource Legality Standard and other related policies.
CertiSource will end provision of the CertiSource Legality Assurance System (CLAS) on 31st December 2020. The decision to cease operation of CLAS was taken against a background of gradually falling volumes of CertiSource timber exported from Indonesia. This is partly due to the growth, since 2016, of the Indonesian Timber Legality Assurance System (SVLK) which is required for issuing FLEGT licences to verified legal timber products exported to the EU. This decision is also partly due to the increasing availability and demand for sustainably managed forest sources.
