Its a minefield also unless EVERYTHING in the container belongs to one person... receipts all need to be to the same name in order to have a smooth ride through customs.
Not something id be happy to do unless i knew the importer

If I packed machines correctly with all paperwork in order and then the container needed fumigation or needs inspection because another guy didn't, then I would not pay fumigation costs, transport costs and other costs ? Hmmm..

Amusement machines have tariffs which would apply to my machines - would the importer know that, or claim it for themselves ? Who pays for damages if they occur ?

As Gavin said, EVERYTHING need to be in one name.
