If you plan to sell a bedside sleeper in the United States, you must comply with several test certificates and safety standards to ensure that your product is safe for consumers. Here are the most important certificates and standards required:

1. CPSC Standards: The Consumer Product Safety Commission (CPSC) is a federal agency that sets safety standards for consumer products. Bedside sleepers must comply with CPSC standards, which include regulations on design, labeling, and testing. The standards are intended to prevent potential hazards, such as suffocation or entrapment.

2. ASTM Standards: The American Society for Testing and Materials (ASTM) is a non-profit organization that sets voluntary safety standards for products. ASTM standards for bedside sleepers include criteria for stability, structural integrity, and entrapment hazards. Compliance with ASTM standards can help ensure that your product is safe for use by consumers.

3. JPMA Certification: The Juvenile Products Manufacturers Association (JPMA) is a trade association that provides certification for juvenile products, including bedside sleepers. JPMA certification ensures that the product meets safety standards set by the CPSC and ASTM. JPMA certification can help you demonstrate to consumers that your product is safe and reliable.

4. Third-Party Testing: Bedside sleepers must undergo third-party testing by a CPSC-accredited laboratory to ensure compliance with safety standards. Test reports must be provided to the CPSC and made available to consumers upon request. Third-party testing can help ensure that your product is safe and compliant.

5. Flammability Testing: Bedside sleepers must also undergo flammability testing to ensure compliance with federal safety standards. Tests are conducted using open flame or cigarette ignition sources to determine the product's flame resistance. Flammability testing can help ensure that your product is safe in the event of a fire.

In conclusion, selling a bedside sleeper in the United States requires compliance with various safety standards and test certificates to ensure that the product is safe for consumers. By adhering to these standards and certificates, you can ensure that your product is safe and compliant, protecting both consumers and your business.
