In Hong Kong, activation codes for the Booster Course Pass are additionally distributed in physical Nintendo Switch game cases, though buyers must own a copy of the base game to be able to use a code. The Booster Course Pass can be purchased on its own, but it is also included in a Nintendo Switch Online + Expansion Pack subscription, as well as in the digital-only Mario Kart 8 Deluxe Bundle (Game + Booster Course Pass). The pack also makes Mario Kart 8 Deluxe the first Mario Kart game to feature classic courses from games following the original game's release, with Mario Kart Tour and its reappearing courses debuting after Mario Kart 8 Deluxe was initially released. The pack marks the longest gap between the original release of a Mario game and the release of its DLC, with the first wave releasing nearly five years after Mario Kart 8 Deluxe did.

All waves are set to be released by the end of 2023. The pass is being released through six waves, with each wave containing eight total courses (divided into two cups of four courses each). In addition to the courses, starting with Wave 4's release, the pass also features additional playable characters for the game, which also return from other Mario Kart games. The courses are based on their designs from Mario Kart Tour, but with visual improvements and new music arrangements. The pack includes twelve additional cups, for a total of 48 additional courses (bringing the total number of courses in the game to 96), most of which are remastered versions of courses from other Mario Kart games, including Mario Kart Tour.
