As the U.S.-China trade war continues to escalate, California Proposition 65 has drawn increasing attention across industries. In recent years, annual fines for non-compliance have reached tens of millions of dollars. Today, HB Testing will explain what Proposition 65 testing entails and how children's dancewear can comply.

What is California Proposition 65 Testing?
California Proposition 65 (Prop 65), officially known as the Safe Drinking Water and Toxic Enforcement Act, is a California law requiring products containing chemicals known to cause cancer, birth defects, or reproductive harm to carry clear warning labels.
Regulated Substances: The current list includes 1,000+ chemicals, with common restricted substances such as:
Lead (Pb)
Cadmium (Cd)
Phthalates (e.g., DEHP, DBP)
Formaldehyde
Polycyclic Aromatic Hydrocarbons (PAHs)
Flame Retardants
What Tests Are Required for Children's Dancewear?
Since children's dancewear (e.g., leotards, ballet skirts) comes into direct contact with skin, the following substances are of particular concern:
Lead (Pb) | ≤100 ppm (coating/substrate) | Prints, zippers, metal buttons |
Cadmium (Cd) | ≤300 ppm (surface coating) | Dyes, decorative sequins |
Phthalates (6P) | ≤0.1% (per item) | PVC decorations, elastic fibers |
Formaldehyde | ≤75 ppm (≤20 ppm for infants) | Wrinkle-free fabrics, adhesives |
PAHs | ≤1 ppm (accessible parts) | Black rubber soles, print coatings |
