Hi,
Well given the amount of legislation involved in shipping live mammals and the extreme expense of it in relation to the value of an ASF I'd say both you are the seller are in no way advised to try and go ahead with this.
They would need metal, escape proof cages that would have to conform to some strict criteria in terms of ventilation and security. There would need to be vetinary checks - probably at both ends.
There would certainly be extremly serious repercussions for not following those laws as well.
