Proposition 65
Proposition 65 is a law in California, U.S., that requires warning labels and other measures regarding exposure to specific chemicals, and it is not a system for certifying products themselves.

Definition and regulatory position
Proposition 65 is a California state law formally called the Safe Drinking Water and Toxic Enforcement Act. It imposes obligations on businesses to provide warnings and take other measures regarding exposure to chemicals that the state has designated as linked to cancer, reproductive toxicity, and other hazards.
In fabrics and apparel, Proposition 65 compliance generally refers not only to the chemicals contained in the product, but also to evaluating the possibility of human exposure during use and confirming warning obligations as needed. It is different from certification marks and blanket safety certifications.
Scope and how to think about the criteria
The list of regulated chemicals is managed by the state and may be added to or changed. In textile products, the scope of confirmation extends from materials to accessory materials and processing, including dyes, pigments, print inks, resin finishing agents, water repellents, plasticizers, and metal accessories.
Judgment is based not only on whether a substance is present, but also on the type of chemical, concentration, migration from the product or contact conditions, and the intended use. For some substances, the state may indicate criteria for exposure levels.
- Whether it falls under the state's designated substances
- How exposure conditions differ between the fabric alone and the finished product
- Who the intended user is and how the product will be used, such as for infants and young children
- Whether it is planned to be sold or distributed in California
Checks in fabric sourcing and product making
When sourcing fabric, do not judge based only on a description such as Proposition 65 compliant; confirm the target substance, target part, test method, test date, and target lot. Even if there are fabric test results, they do not guarantee compliance of the finished product after post-processing, printing, or sewing accessories are added.
Product specifications should clearly state the sales region, applicable laws, controlled substances, whether testing is required, and the division of responsibilities. It is operationally important to collect information including dyeing factories, printing factories, and accessory suppliers, and to be able to recheck it when changing colors, processing methods, or substitute accessories.
Notes on labeling and certificates
Whether a warning label is required is a legal judgment based on the product category and exposure assessment. Displaying a warning does not mean that content restrictions have been met, and a test report proving that no warning is necessary is not necessarily issued.
Supplier declarations of conformity, test reports, and chemical management documents each have different purposes and scopes. The required documents also vary depending on the roles of the seller, importer, brand, and manufacturer, so compare them with contract terms and customer requirements, and consult an expert if necessary.
Differences from similar terms
The REACH Regulation is the European Union's chemical regulation, and its target region, mechanism, and obligations differ from Proposition 65. PFAS regulations and phthalate regulations are also regulations concerning specific groups of substances, but Proposition 65 differs in that it centers on exposure to state-designated substances and warnings.
OEKO-TEX and bluesign are third-party certifications or standards related to textile products and manufacturing processes. Obtaining or complying with them can serve as a reference for chemical management, but that alone does not determine whether a warning is required under Proposition 65.
Frequently asked questions
If the fabric complies with Proposition 65, can the finished product be sold as is?
Not necessarily. In the finished product, printing, labels, buttons, zippers, adhesives, and other components are added, and the contact conditions during use differ from those of the fabric alone. Based on the sales region and finished product specifications, confirm the documents and required tests for each relevant part.
Does Proposition 65 certify that a product contains no hazardous substances?
No. Proposition 65 is not a certification system, but a California state law that sets out warnings and other requirements regarding exposure to designated chemicals. The name and scope of compliance certificates vary by issuer, so confirm the target substances, product parts, and lot.
Is confirmation necessary for apparel sold only within Japan?
If it is not sold, exported, or distributed for California, this law is usually not a direct sales requirement. However, if future exports or customer voluntary standards are anticipated, collecting chemical information from the fabric stage makes verification smoother.
