When you purchase or install network cables, you will often notice that almost all Ethernet cable boxes are printed with some symbols, such as CE, UL, RoHS, FCC and CMP. These marks are not decorative prints but are legally binding and industry-recognized compliance certification marks, corresponding to different countries or regions' mandatory or voluntary technical standards and regulatory requirements. Although they all indicate that the product complies with specific specifications, their application scope, certification entities, basis for regulations and testing requirements are all different.
The reason they matter is practical, and not all network cable certifications refer to the same aspect. Some marks confirm the cable is safe to run inside your walls without creating a fire risk. Others confirm it meets the legal requirements of the country in which it is being sold. A few confirm that the materials inside it do not contain substances restricted by environmental law. Get the wrong one for your situation, and you may end up with a cable that fails an inspection, breaks a local code requirement, or does not perform to the spec sheet's claims.
This guide walks through every mark you are likely to see on network cable certifications and networking accessories. Each section covers what a mark actually verifies, where it applies, and what to check before you buy. A quick-reference table appears right below this introduction. Use it to identify an unfamiliar mark fast, then read the corresponding section for the full picture.
Expert Tip: Before buying, confirm which region each certification applies to. CE is a European Union (EU) requirement. UL and ETL apply in North America. A cable can carry all three marks and still be missing the fire rating your installation requires.

Safety Certifications (Electrical and Fire Safety)
Safety certifications for network cables tell you that a cable or accessory has been assessed against specific electrical and fire standards, but please note that they do not verify data performance. Each mark in this section applies to a specific region or testing body, so one cable may carry several of them.
CE marking: what it confirms and where it applies
CE marking is the EU's mandatory conformity mark for products placed on the European Economic Area market. For communication cables permanently installed in buildings, the relevant EU framework is the Construction Products Regulation, or CPR (Regulation EU 305/2011). CPR governs cables based on their reaction to fire, not their electrical voltage. Do not assume the Low Voltage Directive applies to passive Ethernet cable. The LVD covers electrical equipment operating between 50 and 1,000 V AC or 75 and 1,500 V DC, a range that does not align with passive communications cable.
CE marking is a manufacturer's declaration, not a third-party quality stamp. Under CPR, notified body involvement in the conformity assessment depends on the cable's declared reaction-to-fire class and the applicable assessment system. A notified body is an organization authorized by the EU to carry out conformity assessments on behalf of regulators. In lower-risk classes, the manufacturer carries the conformity burden directly. In higher classes, a notified body must be involved.
Expert Tip: For cables from outside the EU, ask the supplier for the Declaration of Conformity (DoC). This document indicates which EU legislation applies and the compliance verification assessment.
UL certification: what this mark means
A UL Listed mark means it has been tested by Underwriters Laboratories to the applicable safety standard.
UL is an OSHA-recognized Nationally Recognized Testing Laboratory (NRTL). OSHA recognizes NRTLs to test and certify products against specific safety standards.
For Ethernet cable, a UL listing is relevant as it demonstrates the cable's fire category: CMP, CMR, or CM.
If you are planning for higher-power PoE, check the manufacturer's indications on current load, bundle size, and temperature conditions separately. A UL listing alone does not address those decisions.
ETL certification: the alternative to UL
An ETL Listed mark means Intertek has tested and certified the product to the applicable safety standards for the Canadian and U.S. markets.
ETL is Intertek’s certification mark. Since Intertek is an NRTL recognized by OSHA, an ETL Listed product is tested to the same safety standards as a UL Listed product. OSHA treats ETL and UL listings as equivalent: a cable with an ETL mark has undergone tests to confirm if it meets the same standards as a UL-listed cable. Both have the same weight for code compliance in Canada and the U.S.
Expert Tip: To confirm a listing claim, find the manufacturer name and cable model in the UL Product iQ database or in the Intertek certification database. Do not trust a listing printed in a package if it does not appear in any of those databases.
Electromagnetic Compatibility (EMC) Certifications
Electromagnetic compatibility (EMC) means a device should work properly in its normal electromagnetic environment without creating excessive interference for nearby equipment. EMC compliance also checks that the device is not overly sensitive to normal external interference.
Passive copper cables generally do not need an EMC certification. The requirement is for active equipment that produces signals.
FCC compliance: its meaning for network cables
FCC stands for Federal Communications Commission. In this article, FCC compliance refers to rules for radio-frequency emissions from active electronic devices. For network cables, that means the requirement applies to the device, not to the passive cable that connects the devices.
CE EMC directive: how it differs from the CE safety mark
The CE mark can reflect compliance with more than one EU rule on the same product.
For wired active networking equipment, one part of that compliance covers electrical safety, and another covers electromagnetic compatibility (EMC). This means the device should not create too much interference and should keep working properly when there is normal interference from other equipment.
If the product includes a wireless function, Wi-Fi or Bluetooth, it usually falls under the Radio Equipment Directive instead. In that case, although the CE mark still applies, the product is assessed under a different EU framework.
Expert Tip: Before buying an active networking device for an EU installation, ask for the Declaration of Conformity. It should contain the EU rules that apply to that particular product.
Environmental Compliance Regulations
Environmental regulations limit which substances can be used in cables and network accessories. These regulations apply at the stages of manufacture and sale, not at the point of installation. The purpose is to limit the presence of hazardous materials in products that ultimately become electronic waste.
RoHS: what does it restrict and why does it matter?
RoHS stands for Restriction of Hazardous Substances. Directive 2011/65/EU, amended by Directive 2015/863, restricts ten hazardous substances in electrical and electronic equipment sold in the EU. Some of these limited constituents are: mercury, lead, cadmium, hexavalent chromium, two flame retardants (PBB and PBDE), and four phthalates (DEHP, BBP, DBP, and DIBP).
If a product is within RoHS scope, its EU Declaration of Conformity should list RoHS among the applicable regulations. If a product has the CE mark, this alone does not confirm substance compliance. The DoC is the document that tells you which directives were assessed.
REACH regulation: chemical safety beyond RoHS
REACH stands for Registration, Evaluation, Authorization and Restriction of Chemicals. It is a larger EU chemical safety framework that holds a Candidate List of Substances of Very High Concern, or SVHCs. These are materials that might cause cancer, harm hormonal systems, or stay in the environment without decomposing. If an article contains a Candidate List substance above 0.1% by weight, the supplier has a legal obligation to notify customers under REACH.
WEEE directive: end-of-life responsibility
The Waste Electrical and Electronic Equipment (WEEE) Directive sets rules for the collection, treatment, recycling, and disposal of covered electronic waste. A product is within the WEEE scope if it needs electric currents or electromagnetic fields to work or if it is used to generate, transfer, or measure those currents. Where WEEE applies, the manufacturers or importers must register in EU states where they sell, contribute to organized collection systems, and mark products with the crossed-out wheeled bin symbol.
Expert Tip: For EU business installations, look for a specific RoHS compliance statement in the product data sheet. RoHS compliance and WEEE registration are independent requirements.
Fire Ratings for Ethernet Cables
Fire ratings for Ethernet cables are code requirements in most commercial installations, not optional compliance marks. The NEC, published by the NFPA as NFPA 70, establishes fire rating categories for communications cables under Article 800. Each rating designates where a cable may and may not be installed, based on how the jacket material behaves in a fire. This is the category of network cable certifications that most directly determines what you can legally run in a given space.
CMP (Plenum): when the rating is required by code
CMP stands for Communications Plenum Cable. A plenum is any enclosed space in a building used for circulating air, for example a dropped ceiling that serves as a return-air path for the HVAC system, or a raised floor with active airflow below it. NEC Article 800 requires CMP-rated cable in all plenum spaces. If a cable ignites in a plenum, fumes travel through the ventilation system and spread throughout the building. CMP jackets must pass the NFPA 262 test, which measures both flame travel and smoke generation. Jacket materials are typically fluorinated ethylene-propylene (FEP) or specialized low-smoke PVC compounds.
CMP is the highest NEC communications cable rating. A CMP cable can substitute for CMR or CM in any location, but neither CMR nor CM can replace CMP in a plenum space.
CM (General Purpose): the standard for most residential installs
CM stands for Communications General Purpose and is the baseline NEC fire rating for Ethernet cables inside buildings. CM cable is the right choice for horizontal runs within a single floor — inside walls, along baseboards, or through conduit — in non-plenum, non-riser spaces. Most residential and single-story small-office installations use CM-rated bulk cable.
CMR, or Communications Riser Cable, Riser, sits between CM and CMP on the rating scale. CMR is required by NEC Article 800 for vertical runs that pass between floors. CMR cable can substitute for CM but cannot substitute for CMP.
Expert Tip: Before ordering bulk cable, check if any section of your run passes through a plenum space or a vertical shaft between floors. Many dropped ceilings in commercial buildings are active plenums. Running CM cable through a plenum is a code violation under NEC Article 800, regardless of the cable's data rating.
Performance and Cabling Standards
Performance standards define how cables and terminations must behave electrically to support specific data rates and distances. These are different from safety certifications. A cable that passes every fire rating test can still fail a performance benchmark. When a product references a performance standard, it tells you the electrical specification the cable is designed to meet.
ANSI/TIA-568: the US structured cabling standard
ANSI/TIA-568 is the structured cabling standard of the Telecommunications Industry Association (TIA), accredited by the American National Standards Institute (ANSI). Structured cabling is a standardized cabling infrastructure that supports various hardware uses irrespective of which devices connect to it.
ANSI/TIA-568 defines the electrical technical standards for balanced twisted-pair copper cables across four categories:
- Category 5e at 100 MHz
- Category 6 at 250 MHz
- Category 6A at 500 MHz
- Category 8 at 2,000 MHz
It also stipulates the 100-meter maximum channel length for horizontal runs, wiring patterns T568A and T568B, and performance requirements for patch cords and connectors. The current copper edition is ANSI/TIA-568.2-D.
ISO/IEC 11801: the international equivalent
ISO/IEC 11801 is the international structured cabling standard of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
ANSI/TIA-568 uses a categorization system: Cat5e, Cat6, Cat6A.
ISO/IEC 11801 uses a class system:
- Class D maps roughly to Cat5e performance
- Class E to Cat6
- Class EA to Cat6A
ISO/IEC 11801 is the reference standard for installations in Europe and most regions outside North America.
IEEE 802.3: PoE power and cable requirements
Power over Ethernet (PoE) is the technology that allows a cable to carry both data and DC power to a connected device. Common examples are: PoE cameras, Wi-Fi access points, and VoIP phones.
IEEE 802.3 is the set of Ethernet standards published by the Institute of Electrical and Electronics Engineers (IEEE). Within those standards, the PoE specifications outline how power is sent over data cables along with Ethernet signals.
- IEEE 802.3af (Type 1, 2003) delivers up to 15.4 W at the port.
- IEEE 802.3at (Type 2, PoE+, 2009) raises that to 30 W.
- IEEE 802.3bt (Types 3 and 4, PoE++, 2018) goes up to 60 W and 90 W at the power sourcing equipment, using all four cable pairs.
For higher-power PoE, check the manufacturer's data for conductor size, bundle guidance, and temperature limits. Relying only on cable category (e.g., Cat5e, Cat6) is not enough.
Expert Tip: For higher-power PoE installations, opt for a cable with better thermal margin and follow the bundle size guidance in the data sheet. Cat6A is a common choice for its thermal headroom, but it is not an absolute requirement for all installations above 30 W.
Do All Network Accessories Need These Certifications?
No. Not every network accessory is subject to the same certification requirements. The marks that apply depend on the product type, the region of sale, and how each regulation categorizes the product.
Which network cable certifications are mandatory and which are voluntary?
In the U.S., bulk Ethernet cable inside buildings must have a UL or ETL listing to meet NEC fire-rating requirements. This listing validates jacket fire performance, but not data performance. Standards like ANSI/TIA-568 are optional standards in most jurisdictions, although they describe what category ratings actually mean in practice.
In the EU, permanently installed building cable usually needs the CE marking under CPR, while RoHS and WEEE requirements depend on the product's scope classification under each directive. RJ45 connectors and keystone jacks on the EU market may be subject to RoHS if they fall within the directive's scope. Look at the Declaration of Conformity or product data sheet and do not assume you are covered based only on the product type. FCC compliance is not legally required for passive copper connectors, since they do not produce radio-frequency energy.
Expert Tip: For RJ45 connectors and keystone jacks in EU installations, ask the vendor for the specific RoHS compliance statement in the product data sheet. The CE mark on the packaging does not confirm which legislation applies.
Common Mistakes to Avoid
Considering CE as a quality mark
CE mark confirms regulatory conformity for the EU market. Two cables can carry CE mark and still be very different in terms of construction, conductor quality, and electrical performance. If you want to evaluate data performance, you need performance standards like ANSI/TIA-568 or ISO/IEC 11801, not the CE mark.
Ignoring fire ratings on retrofit runs
Many retrofits involve spaces that are actually classified as plenums, for example, dropped ceilings in commercial offices. Using CM cable in a plenum space is a code violation under NEC Article 800, regardless of the cable's data performance. Confirm the space category before buying.
Treating RoHS compliance as implied by the CE mark
Not all CE-marked products state RoHS compliance explicitly. A product data sheet that lists which directives were evaluated removes that vagueness and shows you if compliance has been audited.
Mixing up performance standards and safety certifications
ANSI/TIA-568 and ISO/IEC 11801 are performance benchmarks, not regulatory marks. A cable can claim a category rating without independent verification. Third-party-verified performance claims have more weight for commercial installations in which channel test results are mandatory for project sign-off.
Expert Tip: If a cable claims a category rating but no UL or ETL listing, confirm the listing in the UL Product iQ database or the Intertek CertSearc database before specifying such cables for any commercial installation.
Conclusion
The marks present on any cable package can be divided into four groups: safety, EMC compliance, category rating labeling, and environmental regulations. Each group indicates a different aspect of the product’s compliance or specification.
Before making a purchase, match the cable’s fire rating to the classification of your installation space, confirm the regional certifications are valid for your installation location, and verify any performance claim against the requirements of the referenced standard. Bookmark this page or save the table we shared above and use it as a cheat sheet; it contains all the marks you will most likely find on a product specification sheet.
Match every certification to the specific requirement it addresses, and you will save yourself the work, time, and costs of installing the wrong cable.
