Due to dealer agreements, there are brands that cannot be shipped outside the USA (like Sector 9 and Burton Snowboards). Information from Link hidden: Login to view
These items are typically carried by a local retailer in your country and they want you to buy it from them.
I also learned that there are tough challenges regarding drop shipping to Norway, the main one being - the Norwegian 25% tax on imports over Â£20.
This tax is collected by the post office and a fee is also charged for collecting the tax. This means that you are limited to selling products with a total value of under Â£20. You are also required to guarantee your product for 3 years.
What I can do is to try search for longboards suppliers for you within Norway, or at least from countries near, as this will make your business feasible. I will update this post once I find something. :)
