I wl change my opinion if you give details about the products and how successful they are in global market. Except jute and agro and other food product I have not heard of anything. Garments may be another one.
I do not think you are an importer and Iajdai is a marketing officer for his company. Why do you want all those details from him? Come and visit BD when there are trade fairs. You will get many information. Or you can visit our High Commission Office and get a lot of information.
