Safety Standard for Portable Hook-On Chairs
Direct final rule - In March 2016, the U.S. Consumer Product Safety Commission (CPSC or Commission) published a consumer product safety standard for portable hook-on chairs based on the ASTM voluntary standard for portable hook-on chairs.

The Consumer Product Safety Improvement Act of 2008 (CPSIA) sets forth a process for updating mandatory standards for durable infant or toddler products that are based on a voluntary standard, when a voluntary standards organization revises the standard. In January 2026, ASTM published a revised voluntary standard. This direct final rule updates the mandatory standard for portable hook-on chairs to incorporate by reference the 2025 version of ASTM F1235. The rule is effective on 19 July 2026, unless the Commission receives a significant adverse comment by 29 April 2026. If the Commission receives such a comment, it will publish a notice in the Federal Register, withdrawing this direct final rule before its effective date.

Safety Standard for Portable Hook-On Chairs (10 pages, in English)
The Danny Keysar Child Product Safety Notification Act, section 104 of the Consumer Product Safety Improvement Act of 2008 ('CPSIA'), requires the United States Consumer Product Safety Commission ('Commission' or 'CPSC') to promulgate consumer product safety standards for durable infant or toddler products. These standards are to be 'substantially the same as' applicable voluntary standards or more stringent than the voluntary standard if the Commission concludes that more stringent requirements would further reduce the risk of injury associated with the product. The Commission is proposing a safety standard for portable hook-on chairs ('hook-on chairs') in response to the direction under section 104(b) of the CPSIA. In addition, the Commission is proposing an amendment to include an additional CFR part in the list of notice of requirements ('NORs') issued by the Commission.
