Safety-approved recognized components drive more confident product design and faster time-to-market
Every reliable electrical product begins with trusted parts. Intertek’s ETL Recognized Component certification helps manufacturers verify the safety and suitability of the electrical components and subassemblies used inside their end products, from power supplies and wiring to PCBs, plastics, and insulation systems.
Unlike certification for finished products, Recognized Component certification focuses on the building blocks that make equipment safe, functional, and compliant. These components are tested and evaluated to ensure they perform correctly within specified conditions (known as “conditions of acceptability”) and can be safely integrated into larger systems. These conditions of acceptability make clear how a component is to be used within an end product. If a component is deemed to be in-use outside the conditions of acceptability, a new evaluation may be required to determine the component’s safety.
For both component manufacturers and end-product manufacturers, ETL Recognized Component certification means greater choice, flexibility, and faster time to market to the United States and Canada. For manufacturers looking for European market access, Intertek's S Mark offers similar component certification in Europe.
What Are Recognized Components?
A Recognized Component is a part or sub-assembly tested for safety and performance before it is built into a final product. These components are not standalone consumer products or “end-products”. Instead, they are designed to be used by OEMs and product developers as part of a certified system.
Typical Recognized Components include:
- AC/DC and DC/DC power supplies, plugs, receptables and chargers
- Transformers, motors, switches, and relays
- Printed circuit boards and electrical modules
- Connectors, wire, cable, and harness systems
- Enclosures, plastics, adhesives, and insulation systems
- Battery components and charging assemblies
By starting with certified electrical components, engineering teams streamline compliance and ensure that each element of their design is pre-vetted for safety.

Why Recognized Components Matter
Recognized components serve a critical role in product development:
- Ensure safety from the inside out: Every internal part of a device is evaluated for safe use in the final application.
- Reduce certification burden later: Using verified components shortens the testing and documentation process for the finished product.
- Accelerate time-to-market: Pre-certified components eliminate unexpected redesigns and delays.
- Strengthen supply-chain credibility: OEMs and buyers prefer suppliers with certified, traceable components.
Whether you're designing industrial controls, medical devices, consumer electronics, or power systems, starting with ETL Recognized Components helps build safer, more competitive products.

Recognized Component Certification - Frequently Asked Questions (FAQs)
Recognized Component Certification is a process that evaluates individual components used within a larger product or system to verify they meet applicable safety and performance requirements. These components are not intended for standalone use but are certified for integration into end products, helping manufacturers streamline overall product certification.
This certification helps reduce redundant testing, accelerates product development, and simplifies the certification process for final products. By using pre-certified components, manufacturers can improve efficiency, reduce costs, and minimize time to market.
Conditions of Acceptability are specific guidelines and limitations defined during component evaluation. They outline how the component must be used, installed, or integrated to maintain compliance with safety standards when incorporated into an end product.
A Recognized Component is certified for use within a complete system and typically has conditions of acceptability that must be met during final product integration. In contrast, a Listed product is evaluated as a complete, standalone item ready for end use and installation without additional certification requirements.
Recognized Components are commonly used in electrical and electronic equipment, industrial machinery, HVAC systems, medical devices, and information technology equipment—essentially any product composed of multiple safety-critical parts.
It provides documented evidence that critical components meet relevant safety standards, which certification bodies can leverage during the evaluation of the final product. This reduces the scope of testing required and supports a smoother path to full certification.
Manufacturers benefit from faster certification timelines, reduced testing duplication, improved supply chain confidence, and easier regulatory approvals. It also enhances product reliability and consistency by ensuring critical components meet established safety criteria.
The process typically involves submitting product documentation, samples for testing, and undergoing evaluation against relevant standards. Once compliance is verified, the component is granted recognition, along with defined Conditions of Acceptability for use in end products.
