Understanding Proposition 65: Why It Appears on Charging Accessories and What It Means for Your Business

If you’ve ever flipped over a charger, cable, or electronic accessory and seen a label saying something like “This product can expose you to chemicals known to the State of California to cause cancer or reproductive harm,” you’ve encountered the famous (and sometimes confusing) California Proposition 65 warning.

At BLOKK Technologies, we believe that compliance and transparency are as important as speed and performance. In this article we break down what Proposition 65 means, why it appears on charging accessories, and how we ensure our cables are built to meet the highest safety standards.

What Is California Proposition 65?

Proposition 65 (officially the Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law requiring businesses to provide “clear and reasonable warning” before exposing individuals to chemicals known to cause cancer, birth defects, or reproductive harm — a list that includes 900+ substances (official Prop 65 chemical list). Importantly, the law doesn’t ban products or materials — it mandates disclosure when exposure could exceed safe thresholds.

Why Charger and Cable Packaging Often Includes Prop 65 Warnings

Electronics and charging accessories fall in this category because they contain materials — plastics, metals, dyes, coatings — that may involve listed chemicals. Examples include:

• Lead: used in solder or plating, and listed under Prop 65 for reproductive toxicity.
• Phthalates: softening agents in PVC jackets, several of which appear on the Prop 65 list.
• Bisphenols (BPA/BPS): sometimes used in plastics or coatings, now listed by California.
• Flame retardants and stabilizers: used for heat resistance, also covered under Prop 65 exposure rules.

The label doesn’t mean a product is unsafe — it means either exposure might exceed threshold limits or the manufacturer is erring on the side of caution. Many companies apply the warning nationally even if the product only triggers the law in California.

How BLOKK Ensures Its Cables Stay Compliant

1. Material Selection & Supplier Control

From the start, every BLOKK cable uses carefully chosen materials. We work only with suppliers who provide compliance documentation for lead, phthalates, and other restricted substances. We use lead-free solder, phthalate-free polymers, and high-quality nylon jackets — a core difference between our cables and generic imports flagged in our nylon vs TPE cable guide.

2. Testing & Verification

Every design is third-party tested for listed chemicals using extraction/migration methods (the same techniques referenced by CPSC lead-in-products standards). We only approve materials that fall below safe-harbor exposure limits and meet our Durability by Design criteria.

3. Exposure Analysis & Documentation

Prop 65 is exposure-based. Our engineering team analyzes real-world contact scenarios (handling frequency, duration, heat or moisture conditions) and combines lab data to certify that cables do not expose users to harmful levels. All documentation is updated annually for our wholesale and retailer partners.

4. Proper Labeling When Necessary

If a component contains a listed chemical that cannot yet be substituted, we apply the required Prop 65 warning on packaging and online listings — just as we handle co-branding and custom packaging for channels like hotel amenity programs and retail distribution.

5. Continuous Improvement & Reformulation

The Prop 65 list updates yearly. BLOKK audits all materials and adhesives regularly. If a new chemical appears, we reformulate and retest — a proactive stance that supports both reliability and growth in scenarios like USB-C transition readiness.

Why BLOKK’s Approach Matters

Consumers are more aware than ever of materials, sourcing, and safety. Generic imports often rely on low-cost plastics or coatings that may trigger Prop 65 warnings. BLOKK uses transparency and compliance to build trust for vending operators, hotel distributors, and retail buyers alike.

A Quick Summary: Why BLOKK Cables Are Prop 65-Compliant

• Every component is screened for Prop 65 substances.
• Materials include lead-free solder, phthalate-free polymers, and rugged nylon jackets.
• Third-party tests verify exposure levels fall below California’s safe-harbor thresholds.
• We maintain full documentation and provide support to eligible wholesale partners.
• Clear labeling practices ensure legal compliance and consumer clarity.

The Bigger Picture: Safety and Trust Through Engineering

Proposition 65 is more than a label — it’s a reminder that every material decision matters. At BLOKK, we view it as an opportunity to demonstrate leadership in quality control and ethical sourcing. Our cables don’t just charge phones quickly; they stand for manufacturing integrity, backed by materials, testing, and transparency.

When you choose BLOKK, you’re choosing fast charging, rugged construction—and a brand committed to compliance and trust. That’s the BLOKK difference.

BLOKK: Strong. Fast. Reliable. And Compliant.
