UL Power Cord Labels
Why UL Certification Is Critical for Power Cord Labels in North America?
Any electrical product targeting the North American market must undergo UL certification testing to ensure compliance with fire resistance, electrical safety, and electromagnetic compatibility standards. UL certification is not just a regulatory requirement—it’s a mark of trust. According to UL 817 (for cord sets) and UL 588 (seasonal decorative products), power cord labels must display critical parameters like temperature resistance, flame ratings, and voltage limits to match specific applications.
Core Specifications of UL-Certified Power Cord Labels (Comparison Table)
Below are the key requirements for UL-certified labels, covering materials, testing standards, and use cases:
| Parameter | UL 817-Certified Labels | UL 588-Certified Labels | General Requirements |
|---|---|---|---|
| Product Type | Extension cords, industrial cords | Seasonal lights, holiday décor | Must comply with UL 969 or PGIS2 |
| Temperature Range | -40°C to 105°C | -20°C to 60°C | Label environmental exposure limits |
| Flame Resistance Rating | VW-1 or higher | VW-1 | Pass UL 94 vertical flame test |
| Voltage Labeling | Rated voltage (e.g., 125V) | Maximum voltage (e.g., 300V) | Match the cord’s load capacity |
| Material | Polyester film, synthetic paper | Waterproof vinyl, synthetic paper | UL-approved weather-resistant material |
| Printing Technology | Thermal transfer, laser engraving | Screen printing, UV inkjet | Ensure durability and legibility |
| Warning Statements | “Choking hazard,” “Keep dry.” | “Indoor use only,” “Avoid heat.” | Align with UL standards and local laws |

Standards: UL 2251 (EV plugs), UL 2594 (charging stations)
-
Label Requirements: High-voltage warnings, flame-retardant materials.
How to Apply UL Labels Correctly? 3 Proven Methods
Ensure compliance and durability with these labeling solutions:
Method 1: Direct Adhesive Labels
-
Use Case: UL 817 power cords (manual or automated application).
-
Benefits: Direct adhesion to cords, clear visibility.
-
Note: Use flexible materials to prevent edge lifting.
Method 2: Flag-Shaped Wrap-Around Labels
-
Use Case: Extension cords, bundled wires.
-
Benefits: Easy installation, reduced human error.
-
Note: Match label length to cord diameter.
Method 3: Hanging Tags
-
Use Case: High-voltage equipment (e.g., UL 2594 EV chargers).
-
Benefits: Double-sided printing, high readability.
-
Note: Secure with nylon ties for pull resistance.
Mandatory Warning Statements & UL Markings
Per UL 969, labels must include:
-
Choking Hazard Warning: E.g., “WARNING: Contains small parts. Keep away from children.”
-
Usage Environment: E.g., “Indoor use only” or “Max temperature: 60°C.”
-
Certification Marks: “UL Listed” or “UL Recognized” with certification code.
-
Electrical Ratings: E.g., “125V, 10A.”
3 Tips for Choosing a UL Label Supplier
-
Certification: Verify UL PGIS2 or UL 969 compliance.
-
Material Compatibility: Select weatherproof, flame-retardant, or flexible materials.
-
Customization: Opt for multilingual warnings, variable data printing, and graphics.
