Trades constitute a transaction between two parties and therefore requires the interstate commerce permit. BUT.... if you gift someone an indigo it does not require an interstate commerce permit. Just make sure the gifting party documents on paper that this is solely a gift. Linking any easterns back to their original interstate commerce permit number is also helpful in case FWS comes knocking. Although FWS would like to be informed of all gifts, I did not see any specific requirement on the interstate commerce permit application that specified this. Hope this help Bob. E-mail me if you have any further questions.
