ASTM F963 is the toy safety standard that US law makes mandatory for children’s toys. Section 106 of the Consumer Product Safety Improvement Act (CPSIA) made it a mandatory consumer product safety standard, and the Consumer Product Safety Commission (CPSC) enforces it through 16 CFR part 1250. The edition named in the regulation today is ASTM F963-23, which the CPSC says applies to toys manufactured on or after April 20, 2024.
Short answer
ASTM F963 is a consensus standard published by ASTM International. For toys sold in the United States it is not optional: the CPSC states that CPSIA section 106 made ASTM F963 a mandatory standard for children’s toys, and the regulation at 16 CFR 1250.2 says each toy must comply with all applicable provisions of ASTM F963-23. Manufacturers and importers then show compliance with a Children’s Product Certificate (CPC).
Definition and scope
ASTM F963 is an ASTM International standard that became federal law by reference. The mechanism matters because it explains why the same document can be described as both “an ASTM standard” and “a CPSC rule”:
- The standard is written and revised by ASTM International.
- The rule is 16 CFR part 1250 (Children’s toys). Section 1250.2 requires toys to comply with the applicable provisions of ASTM F963-23, and section 1250.10 incorporates that edition by reference.
- The scope limit comes from the CPSC’s testing and certification rules, which apply to toys designed or intended primarily for children 12 years of age or younger.
The regulation does not adopt every sentence of the standard. Under CPSIA section 106(a), any provision of ASTM F963 that restates or incorporates an existing mandatory standard or ban issued by the CPSC or by statute is not part of the mandatory standard. The same is true of provisions that restate or incorporate an FDA regulation or an FDA-administered statute. Section 1250.2(b) names section 4.2 and Annex 5 in this context.
How it is used in practice
In practice the standard sits in the middle of a three-step chain, and each step has a different owner:
- Design and manufacture to the edition in the regulation. The edition that counts is the one 16 CFR 1250.2 names, currently ASTM F963-23.
- Third-party testing at a CPSC-accepted laboratory for toys designed or intended primarily for children 12 and under.
- Certification. The manufacturer or importer issues a Children’s Product Certificate stating that the product meets the standard. The CPSC’s toy safety guidance says the CPC cites 16 CFR part 1250 (Children’s toys) together with the applicable ASTM F963 sections.
Who must test, and who only certifies: a sourced checklist
The table below, based on the CPSC toy safety business page and 16 CFR 1250.2, shows which obligation attaches to which product.
| Situation | What the sources state |
|---|---|
| Toy designed or intended primarily for children 12 years or younger | Falls under the CPSC testing and certification requirement: comply with ASTM F963-23 and certify with a CPC. |
| Toy aimed at an older audience (for example 13 and up) | The CPSC says it would not need third-party testing at a CPSC-accepted laboratory. |
| Section 4.1 (Material Quality) | A visual check. The CPSC says it is not subject to third-party testing. |
| Provisions that restate an existing CPSC ban or standard, or an FDA rule | Not part of the mandatory standard under section 106(a) and 16 CFR 1250.2(b). |
| Certificate of compliance | Issued by the manufacturer or importer as a Children’s Product Certificate; section 2 cites 16 CFR part 1250 and the applicable ASTM F963 sections. |
Related concepts
Readers coming from laboratory or procurement work will recognise the pattern: a product standard defines the requirement, an accredited or recognised laboratory generates evidence, and a declaration of conformity travels with the product. The same shape appears in the EU, where CE marking is the manufacturer’s declaration of conformity. For how labs themselves are assessed, see the guide to ISO/IEC 17025 and the comparison of laboratory accreditation bodies. These pages describe general laboratory accreditation; the CPSC’s own list of accepted laboratories is the authority for which labs may issue third-party toy test reports.
Where it matters for labs and supply decisions
Three questions are worth asking of any supplier or test provider:
- Which edition? Ask which edition the report and certificate reference. The regulation names ASTM F963-23.
- Does the CPC cite the right regulation? The CPSC describes the certificate as citing 16 CFR part 1250 and the applicable ASTM F963 sections.
- Is the testing laboratory CPSC-accepted? Third-party testing for toys intended primarily for children 12 and under is done at a CPSC-accepted laboratory.
Products that are not toys, or that target an older audience, follow different routes, and the toy rule should not be assumed to cover them.
Common misunderstandings
- “ASTM F963 is just an industry standard.” CPSIA section 106 made it a mandatory consumer product safety standard for children’s toys.
- “Every sentence of the standard is law.” Provisions that merely restate existing CPSC bans or standards, or FDA rules, are carved out by section 106(a).
- “Every toy needs third-party testing.” The CPSC ties third-party testing to toys designed or intended primarily for children 12 and under, and says the Material Quality check in section 4.1 is not third-party tested.
- “A CPC is a lab report.” It is a certificate issued by the manufacturer or importer, not a document issued by the laboratory.
FAQ
Is ASTM F963 mandatory?
Yes for children’s toys sold in the United States. The CPSC says CPSIA section 106 made it a mandatory consumer product safety standard, and 16 CFR 1250.2 requires toys to comply with all applicable provisions of ASTM F963-23.
Which edition of ASTM F963 applies?
The edition named in 16 CFR 1250.2, which is ASTM F963-23, incorporated by reference in section 1250.10.
Who needs third-party testing?
Toys designed or intended primarily for children 12 years of age or younger. The CPSC says toys aimed at an older audience would not need third-party testing at a CPSC-accepted laboratory.
What is a Children’s Product Certificate?
The certificate in which a manufacturer or importer states that a children’s product meets the applicable requirements. For toys it cites 16 CFR part 1250 and the relevant ASTM F963 sections.
