Get yourself a canet, it simplifies moving a listed set of equipment from one country to another and back without import and export red tape or costs
Use a steel crate , try your local bike shops and see what they have ,
Honda have a good crate , all steel frame with uprights and roof to screw panels onto , only problem with it is its a bit big, ok if you can include your gear and spares in the crate otherwise its wasted space your paying for
Triumph also have a good base ,pressed steel that can be damaged by careless fork lift drivers but improves with 30mm rhs welded under the perimeter,
