I did not request support for sharing data in my application, which was funded. Can I charge requestors for the costs associated with sharing the data?
Yes, as long as such costs are reasonable and not excessive and reflect actual costs associated with complying with the request. These expenses for preparing and shipping the data might include costs of personnel, computing time, supplies, and other directly related expenses. NIH requirements for accountability for various types of income under NIH grants are specified elsewhere, see http://grants.nih.gov/grants/policy/nihgps_2003/NIHGPS_Part8.
