Prop 65 Compliance Checklist: What Every Brand Must Have (2026)

Introduction: Compliance Is Not Optional

If your products are sold in California, compliance with California Proposition 65 is mandatory—not optional.

Many brands misunderstand what compliance actually requires. It is not just a warning label—it is a structured system of evaluation, documentation, and ongoing monitoring. :contentReference[oaicite:0]{index=0}

What Is a Prop 65 Compliance Checklist?

A Prop 65 compliance checklist is a structured framework that ensures your business:

• Identifies chemical risks
• Evaluates exposure levels
• Determines warning requirements
• Maintains documentation
• Monitors compliance over time

A systems-based approach ensures each requirement is supported by documented processes.

Step 1: Regulatory Assessment & Applicability

• Applicability Assessment
• Product Evaluation Checklist
• Market Distribution Review

Key Question: Does your product fall under Prop 65 jurisdiction?

Step 2: Chemical Identification & Risk Evaluation

• OEHHA Chemical List Register
• Bill of Materials (BOM)
• Supplier Chemical Disclosures
• Material Review Documentation

Common Chemicals: Lead, Cadmium, Arsenic, Acrylamide

Step 3: Laboratory Testing & Verification

• ISO 17025 Laboratory Reports
• Approved Lab Register
• Sampling Plans
• Chain of Custody Records

Testing validates whether chemicals are present and at what levels.

Step 4: Exposure Assessment

• Exposure Calculations
• NSRL / MADL Reference Data
• Assumptions Documentation

This step determines whether a warning is required.

Step 5: Warning Determination & Implementation

• Compliance Decision Record
• Warning Requirement Documentation
• Label Templates
• eCommerce Warning Placement

Warnings must be visible prior to exposure across all sales channels.

Step 6: Documentation & Recordkeeping

• Compliance Justification Files
• Testing Records
• Supplier Documentation
• Decision Logs

Your documentation is your defense.

Step 7: Ongoing Monitoring & Updates

• Regulatory Update Logs
• Periodic Product Reviews
• Supplier Monitoring
• Re-testing Schedules

Prop 65 requires continuous monitoring due to frequent updates.
