After having a short glance on the 10Q, I like also this part, beside the good revenues and gross profit:
"8. Construction Costs Payable
Construction costs payable represents outstanding balance to be settled for the first phase of construction of bio-fertilizer facility in Shandong. The balances of construction costs payable as of March 31, 2017 and December 31, 2016 were $257,642 and $255,539, respectively."
Obviously, KIWA is constructing their own fertilizer production facility!! This means much better control on product quality and of course much better gross profit!
Good move of KIWA!!
