Be assured of 100% product traceability to legal forest source and compliance to all regulatory requirements, all along the supply chain.

The Standard

CertiSource is a new approach to timber certification. Timber must be traceable through supply chains where every entity (forests, sawmills and even traders) adheres to strict legal, social and environmental criteria. The CertiSource Standard goes beyond basic legal requirements and puts forest concessions and sawmills on the road to sustainable forest management.

Version 4.03 was published January 2015 and reflects the latest Indonesian regulations. The Standard and associated Policies are updated regularly through wide-ranging stakeholder consultation. If you’d like to be involved in the next round of consultation, please contact us using the form at the end of this page.

The CertiSource Legality Standard for Indonesia 4.03 and associated policies are available for download below. An Indonesian translation is also provided, but note that the English version is the official Standard.

Forests and factories in the supply chain up to the point of export are required to be certified; importers, distributors and retailers are not as the products themselves are certified. Becoming certified is low cost. Contact Double Helix Tracking Technologies to find out how.
