I recently completed the permanent importation of my motorcycle (2008 BMW R1200GS Adventure) into Thailand. I also obtained the green registration book and Thai license plate. The process was long and required a lot of paperwork.
Here are some recommended questions to answer prior to starting an attempt to import a motorcycle into Thailand:
Are you trying to permanently import your motorcycle?
What kind of visa will you be coming to Thailand on?
How well documented is your motorcycle? All original sales documentation? All registration documents? Motorcycle driver's licenses to include expired and international drivers licenses?
There are two Thai government agencies that one needs to interact with in order to permanently import a motorcycle into Thailand:
1. Department of Foreign Trade within the Ministry of Commerce (NOTE: An import license must be obtained as well as an import permit for the motorcycle.)
2. Customs Department (

3. (NOTE: I did contact the Thai Industrial Standards Institute and they informed me that because I was importing a used/second hand motorcycle they did not play a role in the importation process.)
I did have to pay import duties and the motorcycle was depreciated in accordance with the formula that can be found in the Thai Customs link above. The cost wasn't zero baht but it was considerably less than a new or used equivalent BMW.
Once I completed the importation, I then took that paperwork to my local Department of Transport. I filled out more paperwork and paid a small processing fee. Weeks later I received my green registration book and license plate.
AlI personnel that I interacted with at all of the aforementioned Thai government agencies were professional and ethical. I will point out that many of the personnel in these offices are not completely familiar with permanently importing a motorcycle because they just don't see it happen that often. Patience, thoroughness, and professional determination are required. I found that researching the process online, asking a lot of questions, and communicating with each office in person or online to be effective. I started the process over a year prior to shipping my motorcycle.
