No you can trade with anyone even if they are not your friend. You just need to the your friend's friend code, go to "Social" and under "invite" and "send friend code", just enter your friend's friend code like how you normally add friends. Tap "visit" and the "trade" instead of invite. After that tap "New Trade" and you can just send the trade to that friend. See Trade for more information.

Hope this helps =)
