1. A method of tracking a material in a supply chain comprising:
recording a location at which an application device applies a DNA taggant set to a first batch of the material produced by a first supplier of the material, the DNA taggant set corresponding to a tag string corresponding to the first supplier;
receiving the first batch at a processing facility;
comparing the location to a geographic coordinate to verify the location is expected;
selecting a sample from the first batch; and
testing the sample to determine a sample DNA taggant set.
