As of January 1, 2018, the new USA Baseball Bat Standard was implemented. Little League-approved baseball bats that were approved for use for the 2017 season or that do not bear the USABat licensing mark will no longer be acceptable for use in any Little League game or activity as of January 1, 2018. 

All bats that bear the USABat licensing mark will be permissible for play in the leagues and tournaments of the participating youth baseball organizations. In Little League, the USABat bats will be used in the Tee Ball, Minor, Major, Intermediate (50/70), and Junior League Baseball Divisions. Either USABat Standard bats or BBCOR bats must be used at the Intermediate (50/70) Baseball and Junior League Baseball Divisions.
At the Senior League Baseball Division, all bats must be meet the BBCOR standard.

Important Note: These changes only affect the Tee Ball and Baseball divisions and don’t affect any divisions of Softball.
