Little League® International has assembled an online resource page dedicated to baseball bat information that includes the latest bat information, current Little League Baseball rules and regulations governing bats, definition of terms, the moratorium on the use of composite bats, and a series of frequently asked questions, with answers and licensed bat lists.

Please note that as of January 1, 2018, the new USA Baseball Bat Standard will be implemented. Little League-approved baseball bats that are approved for use for the 2017 season will no longer be acceptable for use in any Little League game or activity starting on January 1, 2018.
