16 CFR Part 1501 —— Method for Identifying Toys and Other Articles Intended

The primary objective of this regulation is to identify and prohibit products designed for use by young children (particularly those under the age of 3) that contain or are prone to containing small parts. Due to the natural inclination of young children (aged 0-3) to explore the world through their mouths, any object that can fully enter their mouth could potentially block the throat or airway, leading to suffocation and death.

Scope of Application:

Target Audience: Products designed or intended for use primarily by children aged 36 months (3 years) and below.

Applicable Products: Include, but are not limited to, toys, baby products, and other childcare items (such as rattles, teething toys, plush toys, books, etc.).

What is a “small component”? – Small Component Test Tube.

The most well-known quantitative standard in regulations is the “Small Component Test Tube.” This is a cylindrical device that simulates the diameter of a child’s throat under the age of 3. Its internal dimensions are:

Diameter: 1.25 inches (approximately 31.7 mm)

Depth: 1 inch to 2.25 inches (simulates the depth of the throat)

Specific Requirements:

Under 16 CFR 1501, products that meet the following criteria will be considered hazardous and prohibited from sale:

Small toys: The toy itself can fully fit within the testing cylinder.

Separable components: After the toy has been subjected to simulated normal or abusive use by a child (e.g., dropping, biting, twisting, pulling), the detached components can fit within the testing cylinder.

Fragile items: Small fragments produced by the breaking of the toy can fit within the testing cylinder.

Exemptions and Exceptions:

Not all products containing small parts are absolutely prohibited for use by children under the age of 3. There are certain exemptions, but these typically require extremely stringent additional conditions or belong to items whose functionality cannot be altered:

Paper-based products: such as paper, fabric, threads, yarns, elastic bands, ropes, and the like.

Writing instruments: such as crayons, chalk, pencils (provided they are non-toxic and comply with other regulations, and have ventilation holes in the cap to prevent suffocation).

Specific Baby Products: Certain essential items, such as bottles, nipples, and teething toys (which, by design, are meant to be used for sucking but must be robust and durable and cannot have detachable small parts).

Battery Compartment: If a toy requires batteries to function and the battery compartment must be opened using tools (such as a screwdriver) to prevent children from coming into direct contact with button batteries, it is generally not considered a “touchable” component.

Requirements for manufacturers and importers:

For manufacturers of children’s products seeking to enter the US market, 16 CFR Part 1501 implies:

Design avoidance: During the design phase, it must be ensured that all components (including decorations, eyes, noses, stitching, etc.) remain larger than the test cylinder after foreseeable abuse.

Mandatory Testing: Under the Consumer Product Safety Improvement Act (CPSIA), children’s products must be tested by a third-party laboratory accredited by the CPSC and must provide a certificate demonstrating compliance with 16 CFR Part 1501.
