Wooden bat definitions:   

June 4th, 2013 clarification sent to all team reps:

Legal wood bats:   To be legal, the core of a bat barrel must be made only of wood.  The barrel can be wrapped with a strengthening material (these bats are commonly called composite bats) but the core cannot be anything other than solid wood.  Bats with handles made of composite material attached to a wood core barrel are also legal.  However, any bat with a composite core running the length of the bat is illegal - the barrel core must be wood.   

June 14, 2013 guideline from ruling from protest committee: 

A legal bat is defined as made entirely of wood (ash, maple, birch, bamboo, or other solid piece of wood such as hickory). Composite bats are legal, as long as the barrel is entirely made up of wood or engineered wood product that may include a thin polymer-based coating, and that the handle be made up of wood or a composite material. The bat may not contain any metal or alloy of any kind. Composite bats may not exceed a -3 oz drop. All teams and players are responsible for ensuring that they are using legal bats, and where questions arise, the teams and/or players are responsible for obtaining approval of their bat from the NCBL Commissioner or the Operational Committee.
