- USA Baseball FAQ lists NABF Rookie 10U, Freshman 12U, Sophomore 14U under USABat-approved divisions.
- Some NABF/ETBD tournament packets state 15U–18U must be BBCOR, while for 14U and below it is recommended that bats conform to USA Baseball standards (≤ 2⅝″ barrel, no drop limit stated in that packet).
- NABF publishes a downloadable rulebook PDF on nabf.com/rules — use the current book for your season.
When a tournament packet says “recommended” rather than “required,” ask the TD before game day. Do not treat marketing claims as NABF law.
