The easiest way to do this is to go to any local customs office with all the equipment you intend to register (whether you take it on this trip or not). You will fill out a form indicating the brand, model and serial number if available (sometimes hard to find). An officer will then check your equipment against the list (some or all depending on their mood) and stamp the form. You do not need a sales receipt for any of the equipment. This form is what you take with you to show customs officials on re-entry that you owned the equipment before you left. I have never been asked to provide it but there is always a first time and you sure do not want to pay tax or duty on the stuff. I have no experience on the dock's ( wish I did). A little planning will reduce your stress and you will get better service if you do not rush the customs agent. Good luck
