How origin testing works

How origin testing works

Product sample

Plants carry chemical signatures influenced by where they grow. A product sample is collected, along with its declared species or genus and harvest origin.

Chemical analysis

Laboratories measure the sample’s isotopes and elements to establish its chemical profile. The results are uploaded to World Forest ID’s Evaluation Platform for assessment.

Origin evaluation

Using known-origin reference data and spatial models, the platform assesses whether the chemical profile is consistent with the declared origin, producing a report of findings and limitations.
