It all depents on the goods and volume you are going to import. Custom website is very helpful to find out more information about import and export. If you are going to import goods overseas, then you might need to find a good local business broker / logistic company who has branches or nominated freight forwarder at the country you are going to buy from.

If you are new to this business, better to do your homework before you proceed. There is much more to know than how to get the goods in to your country; it is also very important to know the Trade Terms (INCOTERMS) your supplier quoted for you, normally is FOB or CIF. And then payment term (normally 30% deposit, 70% balance payment against pre-shipment satisfaction or Bill of Lading); also it is very important to nominate someone to inspect the goods for you before shipment. I have to say, there are a lot for you to learn about importing. Good luck!
