Import Car from Qatar to Oman

Hello everyone,

I would like to understand the exact process for importing my car from Qatar to Oman. I plan to drive it from Doha to Muscat via Saudi Arabia (through Batha - Shaybah and directly to Oman border without entering the UAE).

I have a Residence Permit in Oman and I'm aware I need a Saudi transit visa. My only concern is that my car is 2016 model (6 years and 2 months old as of today), and there's no real clarity about any restrictions on the age of the car to import it to Oman (I've heard it is 5 years, but no confirmation and I know Omanis who have brought older cars). Being an expat, I am worried that I may be stopped at the Oman border since my car is more than 5 years old.

Also, is it mandatory to obtain an export license plate in Qatar before leaving? Or can I enter Oman as a visitor and then change the number plate directly through the ROP / concerned Ministry?

Appreciate any advice in this regard.
Thanks,
Param
