Two standards, two marks
- BBCOR .50
- The standard for NFHS high school and NCAA college baseball: a peak BBCOR of 0.500 or less, a drop of -3 at most, a barrel no wider than 2 5/8 inches and a length of 36 inches or less. Marked permanently on the barrel: BBCOR .50.
- USSSA 1.15 BPF
- USSSA's own bat performance standard for its youth divisions. An approved model must meet the USSSA 1.15 BPF standard and USSSA's testing protocol, and the mark is applied permanently by a USSSA-licensed maker, never as a sticker or decal.
NCAA BBCOR protocol and NFHS Rule 1-3-2; USSSA Rule 7.01 and USSSA's licensed bat manufacturers page.
What USSSA allows, by age
- 13U and younger: bats must carry the USSSA 1.15 BPF mark; BBCOR .50 bats and wood bats from a licensed maker are also allowed (Rule 7.01.C).
- 13U: a maximum drop of -8 with the USSSA 1.15 BPF mark (Rule 7.01.C.1). Some 13U events at the 13 Majors level require a -5, BBCOR or wood bat (Rule 7.01.C.1(a)).
- 14U: USSSA's national by-laws make -3 (BBCOR) the 14U national standard from January 1, 2026, so BBCOR or wood, unless the state the event is in has adopted a -5 exception (Rule 7.01.C). States and events differ for the 2026 and 2027 seasons, so the event's own bat rule decides.
- High school (scholastic) events: BBCOR .50 with a drop no greater than -3, or licensed wood (Rule 7.01.C.3).
- A bat stamped with the USA Baseball logo is legal in USSSA events, except where BBCOR or wood is required (Rule 7.01.D).
The practical difference
A USSSA bat can be much lighter for its length than a BBCOR bat. At 13U the drop can be as much as -8; a BBCOR bat is never more than three ounces lighter than its length in inches. A 32 inch 13U bat can weigh 24 ounces, while a 32 inch BBCOR bat weighs at least 29.
The marks are not interchangeable. A bat with only the USSSA 1.15 BPF mark is not legal in high school or college play, where any bat that is not one-piece wood must meet the BBCOR standard. A BBCOR bat, on the other hand, is legal in USSSA's younger divisions, but it is heavier than the bats it is played against.
When to switch to BBCOR
When the league requires it: high school, college, any league that plays by NFHS rules, and USSSA 14U wherever the state or event follows the national -3 standard. Before that, a BBCOR bat is allowed in USSSA but not required. The BBCOR bat size guide sets the leagues out by age, and how to choose a BBCOR bat covers length and weight.
How to check a bat
- Read the mark on the barrel: BBCOR .50, the USSSA 1.15 BPF mark, or the USA Baseball logo.
- The mark must be permanent. A sticker or decal does not count.
- Read the league's own bat rule for this season. It is the authority, and divisions inside one organisation can differ.

Questions
- Can you use a BBCOR bat in USSSA?
- Yes. USSSA allows BBCOR .50 bats in 13U and younger alongside its own 1.15 BPF mark and licensed wood. In 14U its national standard from January 1, 2026 is BBCOR or wood, though a state may adopt a -5 exception.
- Can you use a USSSA bat in high school?
- No. High school (NFHS) and college (NCAA) baseball require any bat that is not one-piece wood to meet the BBCOR standard and carry the BBCOR .50 mark.
- What does the USSSA 1.15 BPF mark mean?
- That the model meets USSSA's 1.15 BPF bat performance standard and its testing protocol. The mark must be applied permanently by a USSSA-licensed maker; stickers and decals are not allowed.
- Is a BBCOR bat heavier than a USSSA bat?
- At the same length, usually. A BBCOR bat has a drop of -3 at most, while USSSA allows up to -8 at 13U: a 32 inch 13U bat can weigh 24 ounces, and a 32 inch BBCOR bat weighs at least 29.
- When does a player have to switch to BBCOR?
- When the league requires it: high school, college, leagues that play by NFHS rules, and USSSA 14U wherever the state or event follows the national -3 standard. The league's or event's own bat rule decides.
