If the goods purchase do not cross the Custom barriers india & sold out of India , there is no GST levy & Such transaction do not cover Under GST . Yes .... as per amendment act 2018 (31) ,dt.29/08/2018, such transaction are being brought under schedule III which is shall be treated as neither supply of good or services. But it is being not yet notify till date , hence not into the force.
Yes for Income tax purpose add profit to your income .
