Cosmetic Supply Chain Transparency Act of 2025

Key Points

• The bill requires cosmetic ingredient suppliers to share detailed safety information with brand owners within 90 days of a request. This includes health hazards, chemical properties, heavy metal testing results, safety data sheets, and full ingredient listings for fragrances and flavors.
• The FDA must create and maintain a list of harmful nonfunctional constituents (contaminants and byproducts) that are known or expected to be present in cosmetics. The initial list must be finalized within 18 months after the bill becomes law, with annual updates after that.
• Suppliers must test for each listed nonfunctional constituent within one year of it being added to the FDA's list, and provide brand owners with a certificate of analysis showing the levels detected, the testing methods used, and detection limits.
• Companies that fail to share required safety data, conduct testing, or maintain supply chain records face civil penalties of up to $10,000 per day for each continuing violation.
• States are explicitly allowed to keep or pass their own stricter cosmetic safety laws, including banning ingredients, requiring more disclosure, or providing greater consumer protections than the federal standard.
