The export of food is feasible all the time! Clearly the health pandemic makes it all but impossible for international buyers and sellers to meet but there is still a need to be able to import export food. If you are new to exporting, then my suggestion would be to identify a handful of potential customers, contact them directly to discuss their needs and then offer to send samples of your produce. Yes, there will be a cost to this, but it is cheaper than going to visit and gives potential customers a chance to assess the quality of your produce.
If you really feel that there is a need to meet in person, then use the current lock down to plan for when restrictions are lifted. Prepare a marketing plan. Prepare marketing materials. And be ready to grab opportunities when they arise.
Depending on the products, there may be scope to collaborate with other businesses in order to sell to customers who need larger quantities and more frequent deliveries than you might be able to guarantee if you are working alone. PROFIT can potentially help to bring businesses together to do this.
