Any Internet retailers of physical goods here?
brk: Yes, I've done this in the past (~10 years ago, but not much has changed).I imported from China, Brazil, the UK and NZ.  Exported/sold to almost every country.For basic consumer goods, the majority of the time you just have to declare the export/customs paperwork properly, and make it clear that any VAT, import duties, taxes, etc. are the responsibility of the buyer.  Just be sure to fill out the paperwork accurately (people will often ask you to under-value items, declare them as a samples, warranty replacements, and so on).You'll likely want to incorporate an official business entity in your state.  Specifics about taxes and regulations vary by state, but generally speaking you can run something like this out of your garage/basement until it gets large enough to warrant consideration of a more formal location.My best advice is probably to find a decent local attorney and have him/her help you with all the initial incorporation paperwork.  This shouldn't cost more than a couple of hundred dollars.  You will also likely have other legal questions from time to time with this kind of operation, and it's helpful to have a relationship with someone who can give you good legal guidance and help you deal with any regulatory issues and so on.For shipping, get a UPS account.  They have a nice API and you can get real-time shipping quotes easily.  Tack on $5-$10 for each order to cover packaging costs.Stocking inventory depends on anticipated volumes.  I started by placing small orders for items, and when adding new products would do some hyping and offer "pre-ordering" to get a feel for demand before stocking up.  You will learn to get the feel of it, and because there are 1,000,000 different niches, I can't suggest anything more detailed.  Also, if you can get products locally, even at much higher prices, it can be helpful to first source locally, even if you don't make much profit, to get a feel for demand, and then order direct.
