In March 2014, the U.S. Consumer Product Safety Commission (CPSC or Commission) published a safety standard for soft infant and toddler carriers under section 104 of the Consumer Product Safety Improvement Act of 2008 (CPSIA). The standard incorporated by reference ASTM F2236-14, Standard Consumer Safety Specification for Soft Infant and Toddler Carriers, the voluntary standard for soft infant and toddler carriers that was in effect at the time. ASTM has now issued a revised standard, ASTM F2236-24. Consistent with the CPSIA, this direct final rule updates the mandatory standard to incorporate by reference ASTM's 2024 version of the voluntary standard.
