Hi
In order to import used fishing gear to Iceland, you must have certfication to prove that you have disinfected all your gear, including rod, wheels, waders etc.

We can expect the same for all used kayak gear
(Boat, paddle, PFD, wetsuits/drysuits etc)
But after you have imported your gear, you are ok.
