Baseball and Softball Equipment For Sale

Explain this:

The NFHS has moved the compliance date for composite baseball bat changes forward from 2011-2012 to 2010-2011. This means that any composite baseball bat used during the 2010-2011school year must:
1) meet the Batted Ball Coefficient of Restitution (BBCOR);
2) be labeled with a silkscreen or other permanent certification mark;
3) and have the certification mark that is rectangular, a minimum of a half-inch on each side and located on the barrel of the bat in any contrasting color.

This rule does not pertain to BESR Aluminum Bats nor does it pertain to Softball.
