I cannot add much more to the above. I imported an RV-9 from Florida and had it up and running within two weeks of it's arrival in a container.
You don't need an export CofA but I advise you to have an expert look at the aircraft before you buy and do a thorough prebuy inspection. A multiple offender homebuilder, familiar with the type and preferably also an A&P/IA can do the job and safe you a lot of money and trouble.
Make sure that your country accepts the US CofA as a basis to issue a local CofA and CofR. In my country this was no issue but other authorities may be more difficult to convince.
Make sure there are no loans resting on this plane. Spend some money on a title search. Payments can be done through an escrow service. However, consider that they charge a lot of money. I bought from somebody that I didn't know and felt it was worth the money specially since I convinced the Seller that it was in his favour too after which his agreed to pay half the the costs.
Also check transportation costs and import taxes.
Most importantly, have it dismantled and packed by an experienced company. Craige Vince is a good one on the West Coast and mine was done by Southeastaero in Florida (

If you have any specific questions about transportation (I did a F8 Falco before and ferried it from Oregon), just let me know. Be glad to answer a!
Good luck !
