What is isotope testing and how does it verify cotton origin?

Isotope testing measures naturally occurring ratios of stable isotopes (e.g., hydrogen, oxygen, carbon) within the cotton fiber. These isotope “fingerprints” are shaped by environmental factors such as rainfall, temperature, and soil composition unique to each region and/or subregion. By comparing a sample’s isotope profile to our global cotton reference database, GenuTrace can assess whether the cotton is consistent with a claimed country or region of origin.

GenuTrace delivers scientific traceability solutions that verify the origin of raw materials and finished products. By combining forensic tracers, stable isotope analysis, and advanced digital technologies, we empower brands, manufacturers, and retailers to build transparent, secure, and ethical supply chains.
