The mark of trust 

Due diligence is a continuous process, just like quality control.

Nature's Barcode™ is a comprehensive risk-based approach to verification, which brings you quality and legality assurance on your timber product.

All Nature's Barcode™ products are verified by DoubleHelix to be legally harvested and manufactured with consistent species and origin of raw material.


Tap on our scientific expertise

We always incorporate scientific testing where possible into your customised Nature's Barcode™ verification system.

This means independent verification of claims of origin and/or species through various methods, such as DNA or isotope analysis. Helping you understand which scientific approach would be the most suitable is a key part of DoubleHelix’s service.

Like quality testing, the Statistical Process Control approach is used. This means not every piece of product needs to be tested in order to be sure.
