Hello Antonio,
The exporting of your final product is outside may area of expertise.
I do know that when you export something, you have to assign it an ECCN. Since your product involves RF, there will be certain requirements and certifications that would need to be filed before you can export them to the USA. These rules and regulations would fall under the FCC. Every country has there own particular certifications, i.e. Japan, that you must provide.
You could search the internet for how to export your Bluetooth device or visit the www.bluetooth.org. Perhaps when you become a member of the special interest group (SIG), they will provide you with the guidelines you need for certification and export.
Thanks,
