Deliberately choosing to not not conduct business with certain groups on the basis of their political ideologies is a political action. It implies a disposition toward trade and exchange that is itself political.

Consider the fact that you cannot legally offer a service or a fee to terrorist groups (however that may be defined), money launderers, industries from countries under sanctions... the list goes on.

These limitations are political in nature and could be revised, expanded, or eschewed via political action. But even if they were all eliminated, this would not constitute a "depoliticization" of trade: such an action could be characterized variously as libertarian, free-market, laissez-faire, or something of that nature but it would nevertheless be explicitly political.
