A market gets chosen because someone met a distributor at a trade fair, because a relative lives there, or because a headline said the sector was growing at nine percent. Sometimes that works. More often the tariff advantage turns out to be unusable, the payment cannot be repatriated, or the transit time destroys the product before it arrives.
The alternative is not more research for its own sake. It is a short, structured elimination against criteria that actually determine whether a shipment is profitable, applied to a defined list of candidate markets, scored, and reduced to a shortlist you can defend to a board or a lender.
