North American market - FCC/ISED and NRTL Safety

Access the North American market with FCC/ISED (EMC and radio frequency) and UL, ETL, CSA... certifications.

Accessing the North American market FCC / ISED certification and NRTL trademarks Why certify your products for the North American market? The marketing of electrical and electronic equipment in North America (USA and Canada) requires compliance with strict regulations on electromagnetic compatibility (EMC), electrical safety and use of the radio frequency spectrum. These regulations are defined by bodies such as the Federal Communications Commission (FCC) in the United States and Innovation, Science and Economic Development Canada (ISED, formerly Industry Canada). Special requirements apply to medical devices (MDs).In addition, safety certifications are required by Nationally Recognized Testing Laboratories (NRTL) to guarantee the protection of users and infrastructures. Ask for a quote Our services for regulatory compliance in the United States and Canada We support manufacturers and exporters in their certification procedures with specialised services:FCC and/or ISED testing and certification for radio and digital equipment.Access to NRTL marks for electrical safety (UL, CSA, ETL...).Electromagnetic compatibility (EMC) and interference immunity testing.Compliance management for access to the North American market.Assistance in obtaining local and international certifications. FCC certification for the USA: A requirement for radio and electronic equipment Determining the applicable FCC rules Identification of technical and administrative requirements according to product type.Application of FCC Part 15, Part 18 and other relevant regulations. Selecting the approval procedure FCC Certification: Required for radio transmitting equipment (Wi-Fi, Bluetooth, cellular, etc.).Supplier's Declaration of Conformity (SDoC): Applicable to digital equipment without a radio module.

Harmonisation between FCC and ISED Mutual recognition of tests between the two authorities.Requirements specific to each market (labelling, bilingual documentation, etc.). Electrical equipment safety: NRTL certifications Unlike Europe (CE marking), there is no single government mark for electrical safety in North America. Instead, independent laboratories (called NRTL, recognised by OSHA) certify that a product is safe according to the applicable UL/CSA standards. The product will then bear a safety mark such as UL, CSA or ETL, recognised by the American and Canadian authorities.This certification is essential for installing equipment in many contexts (commercial buildings, factories) and is highly recommended for all electrical products sold to the general public, as it engages the manufacturer's liability in the event of a safety defect. Why choose the expertise of the Emitech Group? Our experts can help you simplify and optimise your certification process:Identification of regulatory requirements specific to your product.Planning and carrying out FCC, ISED and NRTL tests.Optimising certification processes to reduce lead times and costs.Documentary support and marking in compliance with North American regulations.We offer you support from the very start of your projects.

Comprehensive FAQ on CE marking What is CE marking? The CE marking indicates that the product complies with the essential requirements of the applicable European legislation, allowing it to circulate freely within the European market. Which products must carry the CE marking? CE marking is compulsory for all products covered by one or more European directives, such as electrical, electronic, radio or medical equipment. Where should the CE marking be affixed? The CE marking must be affixed directly to the product or to its identification plate. If this is technically impossible, it may be affixed to the packaging or accompanying documents. Which laboratories carry out the tests required for CE marking? The Emitech Group carries out accredited laboratory tests in Electromagnetic Compatibility (EMC), Radio and Electrical Safety to meet the requirements of the three corresponding directives. What exactly does CE marking mean on a product? By affixing the CE marking, the manufacturer declares under its sole responsibility that the product is in conformity with the essential requirements of the applicable European legislation, and that the relevant conformity assessment procedures have been followed. Is a product bearing the CE marking necessarily manufactured in the European Union? No, the CE marking only indicates that the product meets the essential requirements, but does not specify the geographical origin of the product. Do all CE-marked products require the intervention of a Notified Body? No. Only certain high-risk products (e.g. radio equipment, lifts, certain industrial equipment) require conformity assessment by a Notified Body. Who is responsible for affixing the CE marking? The manufacturer or his authorised representative established in the European Union is responsible for affixing the CE marking. However, if a distributor or importer markets a product under its own name, it assumes the manufacturer's responsibilities. What is the legal size of the CE marking? The minimum height of the CE marking is 5mm. However, exceptions are possible for very small products. Can a product with CE marking bear other markings? Yes, provided that these additional markings do not cause confusion with the CE marking, do not reduce its visibility and meet other specific requirements (e.g. energy labelling). What are the penalties for incorrect CE marking? Penalties vary according to the national legislation of the Member States. They may combine administrative penalties (withdrawal of the product from the market, consignment of the goods to the company's warehouse) and criminal penalties (fines and imprisonment). Where can I get more information? Further information on CE marking is available on the European Commission's official website: CE Marking. Why choose Emitech to make your products compliant?

UKCA & UKNI marking, post-Brexit compliance

Master the post-Brexit requirements to access the UK and Northern Ireland markets. Assessment, certification and CE/UKCA marking.

UKCA marking & UKNI marking Access to the UK market and post-Brexit regulation Why is UKCA marking essential for marketing in the UK? Since the United Kingdom left the European Union, the regulatory compliance requirements for placing products on the market have changed. The UKCA marking (UK Conformity Assessed) has become the UK equivalent of the CE marking and is mandatory for selling certain products in Great Britain (England, Wales and Scotland). It co-exists with the UKNI mark for the Northern Ireland market.Our services enable manufacturers, importers and distributors to :Understand and apply the requirements of UKCA marking and UKNI.Ensure product compliance with UK regulations.Identify the Notified Bodies responsible for conformity assessment.Ensure the transition from CE marking to UKCA and UKNI.Facilitate access to markets in Great Britain and Northern Ireland. Ask for a quote Post-Brexit regulatory context On 1 January 2021, the UK introduced the UKCA marking to gradually replace the CE marking. However, the UK Government announced on 1 August 2023 that the CE marking will remain valid indefinitely for many products sold in the UK.This decision provides manufacturers with increased flexibility, allowing them to continue to use either the CE marking or the UKCA marking after December 2024, except for certain specific product categories. Which products are covered by UKCA marking? The UKCA marking applies to electrical and electronic products, household appliances, industrial equipment, information technology and medical devices, among others.The products that must carry the UKCA marking after December 2024 are those requiring assessment by a UK Notified Body. What are the differences between CE marking, UKCA marking and UKNI marking? MarkingZones concernedRecognitionEuropean Union, Northern Ireland Valid in the United Kingdom until further noticeUKCAGreat Britain (England, Wales, Scotland)Not valid in the EUValid only with CE marking How to obtain UKCA marking Conformity assessment procedure Determine whether the product falls under a regulation requiring UKCA certification.Check whether self-certification is possible or whether a third-party body is required. Testing and certification Tests carried out by a UK Approved Body.Verification of essential requirements equivalent to European standards. Documentation and marking Drawing up of the UKCA Declaration of Conformity, indicating the standards applied and the manufacturer's responsibilities.Permanent affixing of the UKCA marking from January 2025.Retention of technical documents for 10 years after the product is placed on the market. UKNI marking for Northern Ireland Northern Ireland remains aligned with EU regulations, which means that :CE marking is still required** to sell products in Northern Ireland.If a product is certified by a UK Notified Body, it must carry UKNI marking in addition to the CE marking.A product bearing the CE + UKNI marking cannot be sold in the EU. Talk to our experts in CE marking, UKCA and UKNI Contact us Specific requirements and exceptions The UKCA marking does not apply to the following products, which remain governed by other regulations:Medical devicesConstruction productsRailway productsMarine equipmentUnmanned aircraft systemsSpecific rules for these categories will be clarified by the UK government. The special case of medical devices As with other equipment, UKCA marking has been in force since 1 January 2021 for Great Britain, and CE marking (with the possible addition of UKNI) remains in force for Northern Ireland. The UK medical device market is regulated by the MHRA (Medicines and Healthcare products Regulatory Agency).Following Brexit, UK regulations are gradually moving away from European standards, which has led to the introduction of UKCA marking for medical devices (MDs). The July 2024 deadline marked a key milestone in the replacement of CE marking with UKCA marking in Great Britain (England, Scotland, Wales). Manufacturers had to start adapting to this change to avoid any market disruption. However, in 2023, the UK government decided to extend the transition periods for the use of CE marking in Great Britain to give businesses more time to adapt. This extension varies depending on the type of product, and for MDs, the transition period can last until 30 June 2026. MDs that already bear the CE marking can therefore continue to be marketed in Great Britain until that date.  Why choose the expertise of the Emitech Group? Our experts will work with you to facilitate your access to the UK market by helping you to :Understanding applicable regulations and certification requirements.Setting up an appropriate compliance process to avoid administrative bottlenecks.Manage the transition to UKCA marking or UKNI to ensure continuity of sales in the UK.Optimise technical documentation and declarations of conformity Contact us for a quote Need help with UKCA and UKNI compliance?
