If I have taken anything from this thread it is that McMaster Carr is doing due diligence to abide by the rules. Google trans shipping, IEEPA, OFAC, etc, etc. There are a ton of rules and regulations that companies have to go through when they export certain items from the US to foreign countries. http://www.state.gov/strategictrade/resources/c43182.htm As far as the comment about them having no problem doing business with larger companies like Fastenal, of course they will because Fastenal is a legitimate company with huge purchasing power. They make it worth it to MMC to jump through the hoops to sell to them. Filling out paperwork and obtaining export licenses is expensive and time consuming. I understand why they wouldn't want to do it for small orders the are billed to one country and shipped to another.
