Is specific grant aim required for business purpose for research grants?

No. When documenting business purposes for research grants, specific grant aim and location of experiment are not required. Please use common sense and good judgment when documenting business purposes.  For the most part, when purchasing supplies and materials for research grants, a general business purpose such as for research is sufficient unless there is something unusual about the purchase (for example, the purchase of dog food – we would need more than for research as an explanation if a federal auditor were to pull the transaction, and the justification will be needed).
