IATA also provides a decision tree (flow chart) that is similar to the one provided by the DOT. The IATA chart, shown on the right, differs from the DOT chart at the point where the question is asked if there is only a minimal likelihood that pathogens are present. If this question is answered as "yes" on the DOT decision tree, the material/specimen is not subject to requirements of Division 6.2 materials. However, on the IATA chart, if this question is answered "yes," the material/specimen is subject to "Exempt human (or animal) specimen" provisions.
Note that IATA rules apply to transport with the FedEx corporation.
