Understanding Metal Bat Certifications

Understanding Metal Bat Certifications

Feb 19th 2024

Metal and composite bats not only come in many different sizes and weight, but they are also available in several certifications set by official baseball leagues, such as USSSA, BBCOR and USA Baseball. The certification is dependent on the league you play in and your age. Marucci’s metal bats meet these different certifications and clearly have the proper logo of these leagues on every bat.

The following information will help you understand the various standards and certifications and find the best Marucci metal bat that matches your game. However, you may want to check with your local league or coach prior to purchasing a new bat.


BBCOR stands for “Batted Ball Coefficient of Restitution.” If a baseball bat has a BBCOR certification stamp on the barrel or taper, the bat will perform at a max level of .50 BBCOR. Additional requirements for a bat to become BBCOR Certified include a length to weight ratio that is no greater than -3 and a barrel diameter that does not exceed 2 5/8”. The NFHS and NCAA both require the use of BBCOR certified bats, which means high school and college athlete are required to swing them. Older divisions (usually age 14+) in recreational leagues may also require the use of BBCOR certified bats.

USSSA certified bats cover most leagues from ages 5 to 14. USSSA models can have a barrel as large as 2 ¾” to provide a larger hitting surface and, in turn, more confidence for each player. However, every USSSA certified bat must max out at 1.15 BPF (Bat Performance Factor). USSSA regulations are generally utilized for tournaments or “travel ball” made up of different age groups, which determine which size bat should be swung. Older age groups swing lower drop weights, but there is a lot of crossover as kids are growing at different rates. Some players may be stronger than their teammates, which is why there are different weight options allowed. Typically, heavier bats are more durable and can withstand faster swing speeds, or pitching speeds, before denting. Additional information can be found at
