Hello Dereko 1969,
I am a freight forwarder with over 30 years experience in all aspects of customs formalities, shipping (all modes air/sea/road) and international trade.
In order to get the info you require can you tell me the type of "sport goods" you intend to import ? I would be happy to work with you (no charges / fees) in order to properly classify your products in the customs tariff and work out the percentage of duty.
If you PM me with your e-mail address I will forward you a document that will elaborate on the various aspects of importing (and exporting).
Best regards,
