Should these services (sequencing, FedEx shipping, poster printing) be classified under "Subcontracting" or "Other Direct Costs"?

Shipping and printing costs for posters fall under the category of Other Direct Costs. If, in the case of sequencing, this is one of the research activities that would be outsourced to another institution or organization, it would be considered subcontracting. If the research is not performed by the sequencing contractor, it will be classified as a service falling under the category of Other Direct Costs.
