Beyond legal compliance

DoubleHelix is a Certification Body (CB) against a growing number of internationally recognised timber certification standards:


1. CertiSource (Indonesia)

  • The CertiSource Standard for Verified Legal Timber is a standard for Indonesian wood products, when basic legality just isn't good enough.

  • Consignment-based verification ensures traceability back to a certified forest of origin for every shipment, and every entity (forests, sawmills and 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.

  • Flexible, pay-as-you go pricing makes certification affordable even at smaller scale.

  • DoubleHelix is accredited to ISO/IEC 17065:2012 by the Joint Accreditation System of Australia and New Zealand (JAS-ANZ). Accreditation no.: Z4460410SS.

  • Validity may be verified at

CertiSource Public Registers

These registers are updated monthly. To request additional traceability information on your specific product label verification number, please visit


2. Myanmar Timber Legality Assurance System (MTLAS)

  • MTLAS is the first national timber legality verification system for Myanmar.

  • MTLAS is the first step towards Sustainable Forest Management in Myanmar, supported by stakeholders from government, civil society, and industry.

  • The MTLAS Standard covers principles of i) rights to harvest, ii) forest operations, iii) payment of taxes and royalties, iv) other user's rights, v) mill operations and vi) trade and customs

  • DoubleHelix is a registered Certification Body (Registration No.: 03DX/2018)

  • MTLAS Certification Bodies are the only organisations authorised to conduct comprehensive forest and supply chain audits in Myanmar.

  • DoubleHelix provides optional DNA testing of teak timber to authenticate documented claims of origin.

Benefits of certification

At DoubleHelix, our goal is to secure the timber supply chain through the application of scientific methods. The application of DNA testing within the CertiSource system has changed significantly as it has developed over the years. As change continues apace at DoubleHelix, we would like to take this opportunity to correct potential misconceptions that have arisen during the rapid growth and expansion of both DoubleHelix and CertiSource.
