Shipping from UK to US


I have purchased a SUT from an individual in the UK, and I will be taking care of shipping from there to me in Texas. The sale was less than $600USD, so I have received conflicting information about what type of documentation I will need to provide for customs. Has anyone ever done something similar to this? Any assistance would be appreciated.

Standard customs form,provided by shipping carrier & filled out by seller/shipper will contain all information needed.As the purchase was under $800.00 there is no import tax.
I bought a pair of Quads from England for more than $800. No problems and no import duty. This was done on eBay.
Ship DHL. Everything DHL from UK is seamless and fast. FedEx, not even close.
