You have to first find out the countries where consumption of coconut is high but production is inadequate or nil. Most countries surrounding India are having coastal areas and are possibly self sufficient. If you find a far off country, you should consider the shipment cost. It should not make your product too pricey to attract buyers.
Instead why don't you start an industry based on coir? There are several good projects and the Government provides good subsidy. You can contact the coir Board for suggestions.
