Children's clothing, abbreviated as children's clothing, refers to clothing suitable for children to wear. There are various types of children's clothing, including jumpsuits, jackets, pants, sweaters, suits, T-shirts, etc. Children's clothing exports to the United States are applying for California 65 certification, which is also known as the "California 65 Proposal", also known as CA65 or CP65. This is a proposal by the state of California to increase attention to toxic chemicals that can be exposed. The goal is to reduce the risk of exposure of California residents to harmful chemicals.

The California 65 certification in the United States requires the following steps:

1. Understand the California 65 certification requirements: Firstly, you need to have a detailed understanding of the California 65 Act's requirements for children's clothing, including the limit requirements for restricted substances such as lead and phthalates.

2. Product testing: Send children's clothing to an approved third-party testing agency for testing to ensure that the content of restricted substances in the product meets California 65 requirements.

3. Apply for California 65 certification: After the product passes the testing, you can submit a California 65 certification application to the California Environmental Protection Agency. When applying, it is necessary to provide relevant information about the product, such as product composition, production process, testing results, etc.

4. Review and Certification: The California Environmental Protection Agency will review your application, including the evaluation of product testing reports. If the product meets the California 65 requirements, you will receive California 65 certification.

It should be noted that California 65 certification is an ongoing process. Once certified, you also need to ensure that subsequent products continue to meet California 65 requirements and undergo regular product testing.
