Your industry, our focus

Leather DNA Traceability

Leather DNA traceability has been developed by Eurofins | BLC, in partnership with Applied DNA Sciences, which enables extended leather traceability beyond the standard barcodes and hide stamping techniques for commercial production.

The DNA tagging system provides detailed information about the traceability of a piece of leather due to the robust artificial DNA markers that are added at various intervals in the leather supply chain. This level of information also helps to prevent counterfeit goods, which is a major asset to any luxury leather brand.


How does leather DNA traceability work on a commercial scale?

The artificial DNA markers contain information unique to that stage of the supply chain, therefore when the product is complete, the DNA can be extracted from the leather and assimilated to build a picture of all the suppliers involved from farm to retail.


Key Leather Processing Stage How the DNA Tagging System Works


  • Application of synthetic DNA to animals

Slaughter House

  • Authentication check of farm applied tag
  • Application of synthetic DNA to hides/skins (optional)

Wet Blue

  • Authentication check of farm/slaughterhouse applied tag
  • Application of synthetic DNA at the wet blue stage after initial tanning

Split Traders

  • Authentication check - test for DNA recovery following leather splitting, DNA detectable on both grain leather and drop splits (optional)

Leather Finishing

  • Authentication check of wet blue tannery applied tag
  • Application of synthetic DNA during the leather finishing process


  • Authentication check of leather finishing tannery applied tag


Advantages of DNA Tagging Over Other Commercial Methods

This level of leather traceability provides businesses with a reliable source of information which has advantages over barcodes and hide stamping. Barcodes and hide stamping rely on the application of codes after the tanning process, and there is no verification information of information back to the original farm.


Minimising Counterfeit Products with DNA Tagging

The amount of information gained through the leather DNA trackability system gives brands and retailers of luxury goods more provenance over the origins of their products and helps to provide a reliable way of authenticating goods. This in turn help to minimise counterfeit products by verifying the authenticity.

The synthetic DNA tags have unique molecular signatures making them impossible to copy. When applied to finished articles, DNA tags can be recovered and authenticated. Thereby providing forensic evidence of the authenticity of the product. 

The DNA tags form part of a holistic traceability system platform, CertainT which also includes authentication and supply chain data management.
