US Children's Sleepwear Regulations: A Compliance Guide for Apparel Brands
Last updated: October 20, 2026
Children's sleepwear sold in the United States must either pass the CPSC's flammability tests or qualify as "tight-fitting" under strict measurement rules. The standards cover sleepwear in sizes above 9 months up to size 14, and they are stricter than the general clothing standard. Children's sleepwear also needs third-party testing and a Children's Product Certificate, and importers must now eFile certificate data.
The two standards
| Standard | Sizes covered |
|---|---|
| 16 CFR Part 1615 | Sleepwear sizes above 9 months through 6X |
| 16 CFR Part 1616 | Sleepwear sizes 7 through 14 |
The two parts have very similar requirements. The main difference is the size range.
What counts as children's sleepwear?
Children's sleepwear is wearing apparel in sizes above 9 months up to size 14 that is intended to be worn primarily for sleep or activities related to sleep. Pajamas, nightgowns and robes are typical examples.
How you market the product matters. A garment that is marketed, displayed or sold as sleepwear can be treated as sleepwear, even if you describe the cut as loungewear. CPSC staff have warned about children's pajamas sold without complying with the standards.
What is excluded
These items are not covered by the sleepwear standards:
- Diapers and underwear
- Infant garments in sizes 9 months or younger
- Tight-fitting garments that meet the dimensional requirements in the standards
Excluded garments still have to meet the general clothing flammability standard, 16 CFR Part 1610. See US Clothing Flammability Standards.
Your two compliance routes
- Flame-resistant route. The fabric and garment pass the flammability tests. Testing happens at several stages: fabric, prototype and production.
- Tight-fitting route. The garment meets the CPSC's measurement limits and carries the required labeling. Tight-fitting sleepwear is not flame resistant, which is why it must fit snugly. Staff guidance describes the required warning that the garment should be worn snug-fitting.
Design choices such as loose cuts, wide sleeves or long lengths can disqualify a garment from the tight-fitting route.
Certification, testing and eFiling
Sleepwear is a children's product. That means:
- Third-party testing at a CPSC-accepted laboratory
- A Children's Product Certificate (CPC) for each product, listing the applicable safety rules, the date and place of testing and the lab
- Records kept for at least five years
- eFiling: since July 8, 2026, importers must electronically submit certificate data at the time of entry
Children's apparel also has other rules, for example for drawstrings on children's upper outerwear, so check the full list for each product.
What if a sleepwear product fails?
CPSC guidance says that failing sleepwear cannot be sold as children's sleepwear. Options generally include destruction, export with CPSC approval or reworking to improve flammability resistance.
Online selling checklist
- [ ] Product titles and categories reflect the real classification: do not call a non-compliant item "pajamas"
- [ ] Size ranges match the standard's thresholds
- [ ] Tight-fitting garments show the required labeling and fit information
- [ ] A CPC and test reports are on file before listing
- [ ] Supplier documents cover fabric, prototype and production testing
- [ ] eFiling data is ready for every import
Frequently asked questions
Do infant pajamas need to meet the sleepwear standard? Sizes 9 months and younger are excluded, but must meet the general clothing standard.
Can I sell cotton pajamas that are loose-fitting? Only if the garment passes the flammability requirements. Many cotton fabrics need treatment or specific constructions, so test before production.
Is a size 14 nightgown covered? Yes, sizes up to 14 are covered.
What if I sell adult sleepwear? Adult sleepwear falls under the general clothing standard.
