Kiddushin 37 - Mitzvot Done in the Land of Israel and Outside

Every commandment that is dependent on the land applies only in the Land of Israel, and every commandment that is not dependent on the land applies both in the Land of Israel and outside the Land, except for the commandments of Orlah (prohibiting first 3 years of tree's fruit) and forbidden mixtures of planting. 

Then why, in connection with the Mitzva of Tefillin, does the Torah say, "And it will come to pass when God brings you to the Land of Canaanaties...?" - It means to say, "Perform this commandment, for on account of it you will merit to enter the Land."
