Your questions require some very specific legal information that are likely to require research by an attorney, meaning you are not likely to get the answer you need here on Avvo. I recommend doing a search for an attorney or firm in your area who specializes in tax law and/or international law. Someone experienced with internet law would be helpful as well.
Good question: many businesses are clueless about the tax impacts of foreign sales. By asking the right questions now, you can almost always structure your corporate setup to reduce tax burdens and risks.
A US - China reseller will have to consider tax impact both in China and the US. Taxes such as: income tax, sales tax, foreign withholding tax, and revenue tax may apply. Such a business will almost always need to consider, analyze, and implement a relatively simple transfer pricing strategy to reduce tax burden and compliance risk. Again, you'll want to consider these kinds of taxes on both sides of the border.
Finally, such a business may want to consider using a corporate entity in a third-party country to reduce taxes and legal liability. A little time, effort, and cost on this kind of structure can pay off big time going forward.
