US CPSC Issues Direct Final Rule for Non-Full-Size Baby Cribs

SG 024/25

The US Consumer Products Safety Commission (CPSC) has published a direct final rule adopting the latest version of ASTM F406, with modifications, as the mandatory safety standard for non-full-size baby cribs.

On January 31, 2025, the CPSC published a direct final rule to update 16 CFR 1220, the safety standard for non-full-size baby cribs. The rule incorporates ASTM F406-24 (Standard Consumer Safety Specification for Non-Full-Size Baby Cribs/Play Yards) with modifications that exclude sections of the standard that exclusively apply to play yards. The rule will become effective on April 5, 2025, unless the CPSC receives significant adverse comments by March 3, 2025.

The latest version of the standard includes the following changes:

• Updated definitions for ‘play yard/non-full-size crib dependent accessory’ and ‘full accessory’
• Revised section 9.6.3 regarding strangulation warning labels
• Non-substantive changes made to other sections of marking, labeling and instructional literature based on recommendations from ASTM's Ad Hoc Language Task Group

The rule defines a non-full-size baby crib as a bed that is:

• Designed to provide sleeping accommodation for an infant
• Intended for use in or around the home, for travel, in a childcare facility, in a family childcare home, in a place of public accommodation affecting commerce and other purposes
• Has an interior length dimension either greater than 139.7 cm (55 in) or smaller than 126.3 cm (49 3/4 in), or an interior width dimension either greater than 77.7 cm (30 5/8 in) or smaller than 64.3 cm (25 3/8 in), or both
• Includes, but is not limited to, the following:
• Portable crib – a non-full-size baby crib designed so that it may be folded or collapsed, without disassembly, to occupy a volume substantially less than the volume it occupies when it is used
• Crib pen – a non-full-size baby crib with rigid sides the legs of which may be removed or adjusted to provide a play pen or play yard for a child
• Specialty crib – an unconventionally shaped (circular, hexagonal, etc.) non-full-size baby crib incorporating a special mattress or other unconventional components
• Undersize crib – a non-full-size baby crib with an interior length dimension smaller than 126.3 cm (49 3⁄4 in), or an interior width dimension smaller than 64.3 cm (25 3⁄8 in), or both
• Oversize crib – a non-full-size baby crib with an interior length dimension greater than 139.7 cm (55 in), or an interior width dimension greater than 77.7 cm (30 5⁄8 in), or both


• Does not include mesh/net/screen cribs, non-rigidly constructed baby cribs, cradles (both rocker and pendulum types), car beds, baby baskets and bassinets (also known as junior cribs)

A read-only copy of the standard is available in the ASTM reading room.
