Guide de certification des réfrigérateurs de voiture : UL, CE et E-Mark

Inadequate car fridge certification is the primary reason why a container of products gets rejected at the port or de-listed by a major retailer. The compliance landscape is fragmented; a product with valid E-Mark for European vehicle installation may lack the UL mark required for US retail channels. This mismatch between factory documentation and market requirements creates significant risk, often leading to costly sourcing errors and stranded inventory that cannot be legally sold.

This guide serves as a standard operating procedure for verifying the essential documentation for your target market. We will analyze the specific differences between E-Mark for automotive use, UL and ETL standards for US retailers, and the ERP energy labeling required for EU eco-design regulations. We also cover the UN38.3 test reports necessary for legally shipping products containing lithium-ion batteries.

E-Mark (E13/E24): Is It Mandatory for Automotive Installation?

E-Mark certification is mandatory for integrated vehicle systems, but the lowercase e-mark for aftermarket accessories like portable car fridges is optional; these products typically fall under CE/EN 50498 instead.

E-Mark for Integrated Systems vs. Aftermarket Parts

A critical distinction exists between the mandatory uppercase E-Mark and the optional lowercase e-mark. The uppercase E-Mark is a legal requirement for complete vehicles and their core electronic sub-assemblies (ESAs) sold within the European Union. This ensures that integrated systems like engine control units or braking systems meet strict electromagnetic compatibility (EMC) standards. In contrast, the lowercase e-mark applies to aftermarket components and retrofitted accessories. This framework provides flexibility for non-critical add-ons while maintaining strict compliance for parts essential to vehicle function and safety.

UNECE Regulation 10 as the Core Standard

As of 2026, the European Union’s requirements for automotive electromagnetic compatibility are fully aligned with UNECE Regulation 10 (UNECE R10). This regulation establishes uniform technical specifications for verifying a product’s immunity to electromagnetic interference and ensuring it does not disrupt other vehicle systems. Compliance requires comprehensive documentation of a vehicle’s electrical architecture and proof that it can withstand external electromagnetic fields. This standard creates a single, harmonized approach to EMC safety across the entire European market.

Type Approval and National Authority Marks

Manufacturers secure type approval from a designated national authority within a UNECE member country. Upon successful testing and validation against UNECE R10, the authority assigns a unique number that is displayed on the product. This mark serves as a certificate of conformity. For instance, the number E13 signifies approval by the authority in Luxembourg, while E24 indicates approval from Ireland. The presence of this mark confirms the product has passed all required type approval tests.

UL vs. ETL: What Do Major US Retailers Require?

For the US market, major retailers accept both UL and ETL certifications equally, as both labs test products against the exact same North American safety standards recognized by OSHA.

Equal Acceptance by Major Retailers

For any product sold in the United States, major retailers like Walmart, Home Depot, and Best Buy accept both UL and ETL certifications without preference. These marks confirm that a product meets the minimum safety standards required for sale in North America. The choice between them does not create a barrier to entry for mainstream retail channels.

• Both UL and ETL are officially recognized by the Occupational Safety and Health Administration (OSHA) as Nationally Recognized Testing Laboratories (NRTLs).
• As of 2026, compliance requirements for most consumer electronics and appliances are met by either certification.
• The presence of either mark satisfies the core safety diligence required by retail partners.

Identical Safety Standards and Compliance

The primary reason for equal acceptance is that UL and ETL test products against the same set of consensus-based safety standards. For example, if a product is tested to a specific UL standard, ETL will use that exact same standard for its own testing process. A product certified by ETL has passed the same safety testing protocol as one certified by UL, ensuring it is safe for its intended use.

• Products with either mark are verified to meet the same North American safety benchmarks.
• The certification process validates product safety and construction quality, not performance or features.

Market Dynamics and Manufacturer Choice

While UL maintains stronger brand recognition among end consumers, many manufacturers choose ETL for its operational advantages. ETL often provides faster turnaround times and more competitive pricing, which helps brands bring products to market more quickly and cost-effectively. This has led to a significant increase in the presence of the ETL mark on store shelves. The decision to use one over the other is a business strategy, balancing speed-to-market against established brand familiarity.

• ETL is frequently selected for its efficiency, reducing delays in the supply chain.
• UL’s long history gives it a slight edge in consumer awareness, though this gap is closing.
• For B2B buyers, the two marks are functionally interchangeable.

Energy Labeling: Does It Meet EU Eco-Design (Class C)?

In the EU, Eco-Design regulations set the mandatory minimum performance for legal market entry, while the corresponding Energy Label provides the consumer-facing transparency needed for purchasing decisions.

Eco-Design as a Market Entry Requirement

EU eco-design regulations are not optional; they establish the minimum energy efficiency and performance standards a product must meet to be sold legally within the European market. This framework effectively filters out the least sustainable products.

• Compliance is a mandatory prerequisite for market access.
• The regulations aim to reduce the environmental impact of products throughout their entire lifecycle.
• Standards are regularly updated and made stricter, pushing manufacturers toward continuous improvement.

Energy Labeling for Consumer Transparency

Working alongside eco-design, the EU energy label provides clear, standardized information directly to consumers. It is designed to help buyers compare products based on energy efficiency and other key performance metrics at the point of sale.

• Products are ranked on a straightforward A-G scale, with ‘A’ being the most efficient.
• The label must be clearly displayed on all applicable products sold both online and in physical stores.
• It also includes other vital data such as water consumption, noise levels, or capacity, depending on the product category.

What a Class C Rating Means in 2026

A Class C rating signifies that a product meets the necessary eco-design requirements for legal sale in the EU. It represents a solid, mid-tier level of efficiency on the current A-G scale but is not considered a market-leading performance level.

• Class C products are fully compliant and widely available.
• The labeling scale is intentionally designed to be demanding, leaving the A and B classes open for future technological advancements.
• This rating typically indicates a good balance between product performance, features, and energy consumption.

Strategic Importance for Product Development

For any manufacturer, achieving at least a Class C rating is fundamental for accessing the EU market. Targeting higher efficiency classes like A or B can create a strong competitive advantage and appeal to sustainability-focused consumers.

• Energy efficiency must be a core consideration from the initial stages of product design.
• Ongoing research and development are essential to align with evolving standards and consumer expectations.
• A high energy efficiency rating serves as a powerful marketing tool that builds brand reputation.

Battery Regs: Do You Have UN38.3 Docs for Shipping?

UN38.3 certification is a non-negotiable global standard for shipping any product containing a lithium-based battery, ensuring transport safety and market access.

If your product includes an optional removable lithium battery pack, obtaining proper documentation for transport is a critical step. This isn’t a regional preference; it’s a global mandate enforced by all carriers to mitigate fire risks associated with lithium chemistries.

Mandatory for All Lithium-Based Products

UN38.3 certification is a mandatory global requirement for shipping any goods containing lithium-ion or lithium-metal batteries. This rule applies across all transport modes—air, sea, road, and rail. Compliance is the foundation for international market access and prevents costly delays or rejected shipments. At KelyLands, we ensure any product with an optional lithium battery, like our portable compressor fridges, meets this standard before leaving our factory. The regulation is strictly about ensuring safety and preventing thermal incidents during transit.

Key Tests for Compliance

To achieve UN38.3 certification, a battery must pass eight rigorous safety and design tests. These tests simulate a range of potential transport conditions to verify the battery’s stability, durability, and resilience against common transport hazards. Passing these confirms the product is safe under both normal and stressful conditions.

• Height simulation (low pressure)
• Thermal stress and cycling
• Vibration and shock
• External short circuit
• Impact and crush tests
• Overcharging
• Décharge forcée

Exemptions for Non-Lithium Batteries

Products that do not use lithium-based chemistries are not subject to UN38.3 regulations. Our standard car coolers and fridges, which run directly from a vehicle’s lead-acid battery system, do not require this certification. Other battery types like nickel-metal hydride (NiMH) and alkaline are also exempt. This distinction is important for clients sourcing a mix of products, as it simplifies logistics for items without lithium power packs.

Recent Regulatory Updates

The landscape for battery transport is constantly evolving to improve safety. As of 2026, several key requirements are in effect that impact the entire supply chain. These changes increase transparency and add further safety layers, particularly for air freight.

• Manufacturers must now provide a standardized test summary document to shippers or regulators upon request.
• For air cargo, lithium-ion batteries must be shipped at a state of charge of 30% or less.
• A typical certification timeline takes 4–6 weeks, a factor KelyLands incorporates into production planning for any orders including battery packs.

Conclusion

Verifying E-Mark, UL, and UN38.3 certifications is a critical step for gaining market access. These documents ensure your products meet mandatory safety and energy standards in Europe and North America. Proper compliance prevents customs holds, retail rejections, and shipping restrictions for battery-equipped units.
