Why Labels Matter: Understanding CE, E, and e-Marks on Electronic and Automotive Products

Labeling containers and products is nothing new — humans have been doing it for thousands of years. From ancient barrels and sacks to modern electronics and vehicles, markings have always played a crucial role in communication, safety, and regulation.
Today, labels do more than identify contents — they serve as legal assurances of safety, performance, and compatibility across global markets. One glance at the back or underside of an electronic device reveals a cluster of symbols, each packed with meaning. In some instances: the CE Mark, E-Mark, and e-Mark — each with specific certification requirements depending on the product type.
What Modern Product Labels Mean
In today’s global economy, labels are more than stickers — they’re evidence that a product meets technical standards. Here’s a breakdown of common EU regulatory marks and what they mean for certification testing:
CE Mark – Conformité Européenne (EU Compliance)

The CE Mark is one of the most widely recognized labels, found on everything from children’s toys to industrial machinery. It indicates that a product complies with European Union (EU) regulations. CE marking is a requirement for legal sale throughout the EU and many partner countries that recognize CE standards.
Key Directives for CE Certification Testing and Marking:
- Electromagnetic Compatibility Directive (2014/30/EU): Ensures electronic devices don’t emit or are affected by excessive electromagnetic interference.
- Radio Equipment Directive (2014/53/EU): Ensures that radio equipment placed on the EU market supports efficient use of radio spectrum. It also sets EMC requirements, safety, and cybersecurity requirements.
- Machinery Directive (2006/42/EC): Sets safety standards for mechanical equipment.
Products displaying the CE Mark must undergo CE compliance testing against specific European Norms (ENs) that define acceptable performance for the Directives and Regulations that apply. Elite serves as an accredited laboratory and can provide EMC and Radio testing services to support CE compliance. In addition, Elite is a Notified Body for type approval certification for Radio Equipment, when required.
The European Union website Europa provides helpful guidance for labeling and documentation necessary to fully support your CE Mark compliance.

E-Mark – UNECE Compliance for Road Vehicles and Electronic Subassemblies

The E-Mark is a certification label that applies to road vehicles and their electronic subassemblies (ESAs). It indicates compliance with a broad range of vehicle safety, operational, and performance attributes, and is accepted as the regulatory approval scheme for vehicles in many countries around the world. Compliance is assessed through testing and review of the manufacturers production and quality controls, followed by a type certificate issued by a designated Notified Body. Certain electronic subassemblies permanently mounted to the vehicle and having a safety related function are required to be tested and type certified.
Applicable Regulations:
- Regulation (EU) 2018/858: Outlines automotive system requirements including emissions, safety, and EMC.
- E-Mark certification ensures compliance with UNECE’s harmonized automotive standards, streamlining approval for markets that recognize these rules.
e-Mark – EU Regulations for Agricultural & Forestry Vehicles

The e-Mark (lowercase) is designated for agricultural and forestry vehicles, such as tractors and off-road machinery.
Applicable Regulations:
- Regulation (EU) 167/2013 for general safety and classification
- Regulation (EU) 2015/208 for EMC standards specific to this category
What It Means:
The e-Mark shows that a product complies with EU requirements, including electromagnetic compatibility tailored to the needs of agricultural environments. It’s a specialized type of e-mark certification designed to address unique environmental and functional challenges.
Why CE, E, and e-Mark Certification Matters
Whether you’re manufacturing a wireless device, designing an automotive system, or building agricultural equipment, understanding CE, E, and e markings is essential for legal compliance and market access. These labels aren’t just technicalities — they are a passport to global trade.
Finding the Right Marking for Your Vehicle or ESA
Navigating the maze of regulatory requirements can be challenging — especially when it’s not immediately clear which standards or markings apply to your specific vehicle or electronic subassembly (ESA). The correct designation depends on how and where the product will be used.
That’s where Elite’s experts come in. We help you determine which standards apply and what testing is required. With a clear roadmap, you can confidently move forward with compliance testing and stay on track for a successful product launch.
