How strict are the borders with regards to papers for trailers and bikes. Mine was lost in a fire and the authorities are taking their time in reissuing it. I might not receive it in time before my departure. Can I take a change without it?
no easy answer. I presume the bike is on the trailer? Anyway your problem will prob be on the SA side where they will not issue you with the customs form unless you have the papers (or at least a photocopy of these). On Moz side they usually simply just stamp the SA customs form and off you go. Oh make sure you get seguros (3rd party insurance) and Moz TIP (Temp import permit) separately for car, trailer and bike.
You will still need the engine and chassis (VIN) numbers for the forms.
