- USABat is USA Baseball's certification standard for youth baseball bats that establishes a wood-like performance for non-wood bats
- Beginning January 1, 2018, participating National Member Organizations, which include the American Amateur Baseball Congress (AABC), Babe Ruth Baseball/Cal Ripken Baseball, Dixie Youth Baseball & Dixie Boys Baseball, Little League Baseball, PONY Baseball and the NABF, adopted the USABat Standard for youth baseball bats. Additional organizations adopting USABat include Dizzy Dean Baseball and a wide variety of city and county parks and recreation departments around the country
- Following the implementation of the new standard, metal and composite bats must feature the USABat certification mark to be authorized for play in youth leagues within the participating National Member Organizations. Solid, one piece wood bats may be used with or without the USA Baseball mark
- For non-wood and multi-piece wood youth baseball bats (non-TeeBall bats), the USA Baseball mark signifies that the bat has undergone lab testing to confirm that it performs at a wood-like standard and has been certified under USABat
- Bats with the BPF 1.15 stamp are no longer permitted in leagues that have adopted USABat. Some older youth divisions will allow both USABat and BBCOR certified bats
- Retailers and licensed bat manufacturers began selling certified baseball and tee ball bats featuring the USA Baseball mark on September 1st, 2017
