Bangkirai (Shorea laevis)

Origin of harvest

Forest Stewardship Council® certified concession in Central Kalimantan, Indonesia

Thank you for your interest in this bangkirai product from Wood United. We are one of the first companies in the world to use Nature’s Barcode™ to verify that our bangkirai products consistently meet the above specifications.

Benefits of verification

For bangkirai products, using the correct species is key to QUALITY assurance.

The Shorea genus consists of hundreds of closely related, similar looking species, each with slightly different characteristics that can impact strength, lifespan and resilience to pests. Shorea laevis is the highest quality species associated with the bangkirai trade name.


Substitution and associated document fraud is one of the most common ways that illegal timber is laundered into global supply chains.

By using Nature’s Barcode™ in conjunction with our existing FSC® Chain of Custody (CoC) certification, we are taking steps to ensure that substitution does not happen in Wood United supply chains.

Species and origin data will be used to improve product quality and consistency.

Wood United and our supply chain partners are the first to participate in the collection of scientific data for this purpose, from point of harvest through to manufacture. 

Data will be compiled and used to determine correlations between quality characteristics and the local growing conditions associated with harvest location. This knowledge will help to maintain product quality and consistency over time.

Nature’s Barcode™ methodology

An independent party has conducted a comprehensive risk assessment on this product. This has included:

•  supply chain analysis to assess level of traceability back to forest of harvest
•  identification of any risk of species or origin substitution along the product supply chain.

We have then implemented the following controls to ensure that only Shorea laevis from the identified FSC® concession in Indonesia is used to manufacture our products:

Document traceability checks

Random checks are performed on manufacturer production records, log purchase, log transportation, and log delivery.

This process tests the ability of the supply chain to provide, on demand, specific documentation relating to every shipment. 

Wood anatomy (microscopic) analysis

Wood anatomy testing is done to ensure that the timber used in production falls within the correct trade group for bangkirai.

Focused sampling of any material with undesirable characteristics will help determine correlations between quality, species and local growing conditions. 

Onsite inspections

Physical production back-tracks and log reconciliation of log transport and receipt records are done periodically via a factory visit. 

Density analysis

This form of property testing helps to confirm that the timber used in production is of the expected quality characteristics for bangkirai. 

As DNA verification tools become available these will be applied to verify the accuracy of log harvest and transportation records, and provide greater accuracy in determination of species and origin.
