CE mark is a safety certification mark, which is regarded as the passport by the manufacturer 
to open and  entered the European market.  CE stands for CONFORMITE EUROPEENNE. In the EU market, the "CE" mark is a compulsory certification mark. In order to circulate freely in the EU market, no matter the products produced by enterprises within the EU or those produced by other countries, the "CE" mark must be affixed.  To show that the product meets the basic requirements of the EU directive "New Method of Technology Harmonization and Standardization".  This is a mandatory requirement for products under EU law.   
 
Differences between GS certification and CE certification:
 
| serial number | item compared | GS   certification | CE certification | 
| 1 | Certification   of nature   | Voluntary   certification non-compulsory   | Compulsory   certification    | 
| 2 | Scope   of application   | Test   GS according to German safety regulations   | European   standard (EN) is applied for testing   | 
| 3 | The certification   issuing Body   | A   third party authorized by the German government shall conduct the test and   issue the GS certificate   | CE can   be declared on the premise of complete technical documentation (including   test report)   | 
| 4 | Fees  | You   must pay an annual fee   | No   annual fee   | 
| 5 | The   factory audit   | Factory   inspection must be carried out annually   | No   factory inspection   | 
| 6 | The   certificate authority   | The GS   logo is issued by the authorized testing unit, which has high credibility and   market acceptance   | The   factory's self-declaration of product conformity has low credibility and   market acceptance  | 
 
frequently asked questions
Q1. What are the certification types of CE?
A: CE certification is divided into three types: original project, reported project and secondary certification.
 
Q2. What is the difference between the original project, the submitted project and the secondary certification project?
A: The original project is the project for which the product is applied for the first time;
The submitted project is based on the completed project, the applicant, model, trademark and other basic information is changed, and the certificate is re-applied;
The secondary certification project is based on the completed project, the structure of the prototype is different, the difference test is carried out on the basis of the original project, and a new report is submitted for the certificate application;
 
Q3. Under what circumstances can reporting be made?
A: The reported project is based on the same product of the original project, the applicant, trademark and model change. Therefore, on the premise of no change in the prototype, the basic information change can be applied for certificate reporting;
 
Q4. Will there be any new report on the submitted project? Will there be an update of the report on the certificate?
A: The report will not be submitted when applying for the certificate. Therefore, the certificate of the reported project will not have the change of the report number and other information except the change of the basic information.
 
Q5. Under what circumstances can secondary authentication be carried out?
A: The secondary certification is based on the original project. The main board of the prototype remains unchanged, the structure of the prototype is changed, such as the appearance is changed, the screen size of the prototype is changed, the GSM antenna is changed, the adapter or battery is changed, etc., all of which can be applied for the secondary certification.
 
Q6. How to perform secondary authentication?
A: The secondary certification will be based on the original project, according to the actual differences of the prototype, the relevant difference test, re-issue and submit the difference test report, the certificate application;
 
Q7. What is the difference between the certificate of the submitted project and the certificate of the secondary certification project and the original certificate?
 
In the certificate of the reported project, the applicant, trademark, model and basic information are changed on the basis of the original project. Therefore, except for the basic information of relevant changes, other information, such as report number and relevant technical parameters, will be used in the original project.
 
As the certificate of secondary certification will increase the difference test and re-submit the report for review, the certificate of secondary certification will not only change the basic information, but also change the report number on the basis of the original project. The new report number will be adopted, but the related technical parameters will not be changed. In addition, the certificate number of the original project will be reflected in the certificate remarks for both the submitted certificate and the secondary certificate.
