In this article, we address what the CE marking is and how it is obtained, what ISO certification is and how it is obtained, and the legal principles that must be observed throughout the CE and ISO certification processes. In addition to outlining the technical and legal steps manufacturers and commercial companies should follow, we also explain potential legal risks and practical precautions that may arise during these processes.
What Is the CE Marking?
Strictly speaking, the “CE certificate” is not a standalone certificate issued in a single, uniform format. Rather, it refers to the set of documentation demonstrating that a CE-marked product has been manufactured in conformity with applicable EU directives. The CE marking is not a quality symbol; it is an official marking affixed to products that meet all essential health and safety requirements under the relevant directives. Put differently, the CE marking functions as a “passport” that allows a product to circulate freely within the European market.
Within EU legislation, the New Approach Directives define technical requirements for various product groups such as toys, machinery, medical devices, and electrical equipment. Before such products may be placed on the market in EU countries—and in Türkiye under harmonized legislation—they must undergo the relevant CE conformity procedures. For example, according to the Turkish Standards Institution (TSE), products within the scope of the relevant directives cannot enter the EU market without bearing the CE marking. In certain cases, the CE marking may also include the identification number of the Notified Body that carried out the conformity assessment (e.g., “CE 1783”).
In summary, the CE marking represents the manufacturer’s declaration that: “This product complies with the relevant EU/Turkish directives.” The same obligations apply to manufacturers outside the EU. If your product is to be placed on the EU market, it must bear the CE marking where required.
How Is the CE Marking Obtained?
There is no “central approval document” that grants permission to use the CE marking; the responsibility rests primarily with the manufacturer. EU guidance materials typically describe the process through the following steps:
- Identify applicable legislation
First, determine which EU directives apply to the product (e.g., medical device, food equipment, construction product). Identify the essential health and safety requirements set out in the relevant directive(s). - Select the conformity assessment route
Some directives allow conformity to be demonstrated through a manufacturer’s self-declaration, while others—particularly for higher-risk products—require assessment by an independent Notified Body. - Prepare the technical file
Compile documentation demonstrating the product’s design, manufacturing, and performance (instructions, test reports, risk analyses, etc.) into a single technical file. This file must be retained and presented to competent authorities upon request. - Draw up the Declaration of Conformity
If the product complies with the directive(s), the manufacturer prepares and signs an official EU Declaration of Conformity, stating which standards and requirements have been applied to achieve compliance. - Affix the CE marking
Once all requirements are satisfied, the CE marking is affixed to the product (“Conformité Européenne”). The marking must be visible, legible, and indelible.
Official EU sources emphasize that all of the above steps must be completed correctly in order to lawfully apply the CE marking. While “unofficial” or “unauthorized certificates” may appear attractive, they are not legally valid. EU guidance also warns that certain entities may offer “certificates” without proper testing or outside their scope of authority, which can mislead consumers. Accordingly, CE conformity assessments should be conducted only through accredited, competent, and—where required—Notified Bodies operating within the EU or Türkiye.
In practical terms, obtaining CE marking involves selecting the correct directive(s), ensuring technical compliance, undergoing independent assessment where required, and completing the process through the manufacturer’s declaration. There is no centralized “permit”; the process is carried out by the manufacturer and, where applicable, the Notified Body. Using a CE marking without proper compliance may lead to legal sanctions such as administrative fines and product withdrawal/recall.

What Is ISO Certification?
ISO certification signifies conformity with internationally recognized standards. ISO (International Organization for Standardization) sets global standards in areas such as manufacturing, quality, environment, and safety. For example, ISO 9001 is one of the most widely used Quality Management System standards. Obtaining ISO certification indicates that your organization meets the relevant requirements and manages its processes and service quality in line with defined rules.
ISO certification is generally issued as a formal certificate, documenting compliance with the applicable ISO standard. For instance, an ISO 9001 certificate confirms that the organization has implemented a quality management system intended to continuously improve product or service quality and enhance customer satisfaction. While ISO certification is not legally mandatory in most cases, it can offer significant advantages—particularly in supplier selection and international markets.
In addition to ISO 9001, many other ISO standards exist, such as ISO 14001 (Environmental Management) and ISO 27001 (Information Security). Organizations typically pursue certification based on the standards most relevant to their business activities.
How Is ISO Certification Obtained?
Compliance with ISO standards is generally voluntary. The process typically involves the following steps:
- Preparation and Documentation
The organization assesses its current state and reviews the clauses of the relevant ISO standard. It then prepares the necessary policies, procedures, and records required to establish the management system. - Implementation and Audit
After implementation, a preliminary audit may be conducted. Once gaps are remedied, an independent audit is carried out by an accredited certification body. - Certification
If the audit is successful, the ISO certificate is issued and the organization is formally recognized as compliant with the applicable standard. - Surveillance Audits
ISO certificates are typically valid for three years. During this period, at least one surveillance audit per year is conducted to verify continuity and ongoing compliance.
A key point is ensuring that the certification body is recognized by the Turkish Accreditation Agency (TÜRKAK) or by internationally recognized accreditation schemes. ISO certificates are considered reliable when issued by accredited certification bodies; otherwise, there is a risk of holding an “invalid certificate.” Moreover, ISO systems (such as ISO 9001) are strengthened not by the certificate alone, but by demonstrable internal audits and management commitment—meaning the core objective should be sustainable improvement, not merely obtaining a document.
Legal Compliance in the CE Marking Process
Under EU technical legislation, CE marking is mandatory for many product categories. The CE marking indicates conformity with the relevant directive and demonstrates that the product meets essential requirements related to human, animal, and environmental safety. In essence, CE “certification” is the manufacturer’s declaration of conformity. According to EU requirements, before a CE marking may be affixed, compliance must be supported through appropriate internal and external assessments. In Türkiye, within the framework of the customs union and harmonized legislation, CE marking requirements apply similarly to products subject to regulations aligning with the EU New Approach Directives.
Legal Requirements to Observe for CE and ISO
Although CE and ISO processes differ, they share certain compliance expectations. Legal compliance is one of the most critical factors that must not be overlooked:
- Legal Compliance for CE
Full conformity with the applicable technical regulations is required for CE-marked products. The relevant directive(s) must be correctly identified, and the technical file and conformity assessment must be performed in accordance with prescribed procedures. EU authorities and, in Türkiye, relevant public bodies may inspect these processes. Incorrect CE use or reliance on false/unauthorized documentation can lead to severe sanctions. Particular caution should be exercised regarding so-called “voluntary CE certificates”; a Notified Body certificate should be obtained only where required by EU legislation for the product in question. Under product safety and market surveillance regulations in Türkiye, non-compliance may trigger administrative penalties. In addition, after completing the CE process, the technical file must typically be retained for at least 10 years, and it may be requested during official inspections. - Legal Compliance for ISO
While ISO standards are generally voluntary, commercial integrity and legal compliance remain essential throughout the certification process. Nonconformities identified by the certification body must be remedied within prescribed timelines. ISO 9001 and similar systems encourage disciplined process management consistent with principles reflected in the Turkish Commercial Code and the Turkish Code of Obligations. Documentation must accurately reflect reality. For example, an ISO system that conflicts with accounting records may lead not only to certificate withdrawal but also to broader legal exposure.
In both cases, it should be remembered that “obtaining the certificate” is not the end of the journey—it is part of an ongoing compliance framework. Even after obtaining CE marking or ISO certification, continuous internal audits and monitoring of legal/regulatory changes are necessary.
Assessment and Conclusion
CE marking and ISO certification are important tools that enhance product and service quality, safety, and competitiveness. However, if the applicable rules are not followed, these processes may backfire. Mistakes made during product or system certification can harm not only the certificate status but also the company’s reputation.
Accordingly, the priority should be to ensure compliance from start to finish. To strengthen CE marking and ISO 9001 certification on a sound legal basis, it is advisable to:
- Prepare the technical file and quality documentation meticulously,
- Obtain necessary audits through TÜRKAK-accredited bodies,
- Review declarations, commitments, and contracts with legal counsel,
- Monitor regulatory updates throughout the process.
The CE marking and ISO 9001 certificate are not freely distributed logos; they reflect the assurance system behind a product and an organization’s processes.
