The Dutch star has enjoyed two successful seasons at White Hart Lane, but has expressed the desire to return to the club where he spent three years prior to leaving for Real Madrid.
"I can confirm that Rafael is on his way to Hamburg now for a medical," the forward's agent Robert Geerlings said.
Spurs were said to be holding out for £14million (17.5million euros) for the Dutchman after Hamburg initially bid £8million (10million euros) last week, but there now appears to be a willingness to compromise from both sides.
"No fee has been agreed, but when a player goes for a medical it is clear that the two parties intend to find a solution," Geerlings added.
Van der Vaart signed for Tottenham from Real Madrid exactly two years ago just inside the transfer deadline.
