Applicability of Zero Tax Rate in Indirect Distribution Structures

Our company currently only distributes domestic products, but we have recently been given a great opportunity to distribute export goods as well. I am inquiring because I lack knowledge regarding the zero tax rate. Our current structure is A (Exporter), B (Our company, the Distributor), and C (Producer), and we plan to proceed by purchasing products from C and supplying them to A. In this case, can we also receive the zero tax rate application? I am asking because I read a post stating that if you are not an exporter, you cannot receive the zero tax rate. Since this is our first time handling exports, I would appreciate a detailed explanation.
