CE marking indicates that a product has been assessed by the manufacturer and deemed to meet EU safety, health and environmental protection requirements. It is required for products manufactured anywhere in the world that are then marketed in the EU. Conformité Européenne (CE) certification is a regulatory standard that verifies certain products are safe for sale and use in the European Economic Area (EEA). Manufacturers place a CE marking on certified products to indicate that the product complies with European safety rules and can be traded freely within the EEA.
On commercial products, the letters CE (as the logo ) mean that the manufacturer or importer affirms the good’s conformity with European health, safety, and environmental protection standards.  It is not a quality indicator or a certification mark. The CE marking is required for goods sold in the European Economic Area (EEA), but is also found on products sold elsewhere that have been manufactured to EEA standards.
The mark indicates that the product may be traded freely in any part of the European Economic Area, regardless of its country of origin. It consists of the CE logo and, if applicable, the four digit identification number of the notified body involved in the conformity assessment procedure. “CE” is the abbreviation of “conformité européenne” (French for “European conformity”).
he mark on a product indicates that the manufacturer or importer of that product affirms its compliance with the relevant EU legislation and the product may be sold anywhere in the European Economic Area (EEA). It is a criminal offence to affix a mark to a product that is not compliant or offer it for sale.
For example, most electrical products must comply with the Low Voltage Directive and the EMC Directive, among others; toys must comply with the Toy Safety Directive. (The Low Voltage Directive is about electrical safety; EMC or Electromagnetic Compatibility means the device will work as intended without interfering with, or being affected by, the use or function of any other device.) The mark indicates compliance with as many norms (directives and regulations) as apply at the time of the declaration of compliance (see below). In the case of electrical products, several later norms such as the Restriction of Hazardous Substances Directive (RoHS) and Waste Electrical and Electronic Equipment Directive (WEEE) are relevant in addition to the Low Voltage Directive and EMC Directive. The exact significance of the mark therefore depends on when it was applied to a specific unit.
The marking does not indicate EEA manufacture or that the EU or another authority has approved a product as safe or conformant. The EU requirements may include safety, health, and environmental protection. If stipulated in any EU product legislation, assessment by a Notified Body or manufacture according to a certified production quality system may be required. Where relevant, the mark is followed by the registration number of the notified body involved in conformity assessment.
Not all products need CE marking to be traded in the EEA; only product categories subject to relevant directives or regulations are required (and allowed) to bear CE marking. Most CE-marked products can be placed on the market subject only to an internal production control by the manufacturer (Module A; see Self-certification, below), with no independent check of the conformity of the product with EU legislation; ANEC has cautioned that, amongst other things, CE marking cannot be considered a “safety mark” for consumers.
