Why are your LED screens always rejected by overseas customers? Boss Zhang, who just entered the industry, suffered a huge loss last year - the outdoor large screen produced by three months was shipped to German customs, but was detained on the spot because of a lack of paper. That deadly piece of paper is exactly what I want to say today​ ​CE certification​ ​. Novice can quickly increase fans, but LED people who do foreign trade should know that this certification is a "gold pass" to open up the European market.

​​Find out what CE certification is first​ ​. Simply put, it is like our "health certificate", products without this logo cannot be listed in the 28 EU countries. Last year, statistics showed that 38% of LED screen returns were caused by certification issues. Especially for live products such as outdoor display screens, the certification requirements are stricter than indoor screens.

Recently, I have always been asked: "Can you just find an agent to handle it?" "There are so many ways here. The most outrageous situation I have ever seen is that a manufacturer uses the certification documents of the indoor screen to apply for outdoor products, but was blacklisted by the EU. ​ ​The key is to identify three points​​：

1. The test report must contain EMC (Electromagnetic Compatibility) and LVD (Low Voltage Command)
2. Outdoor products need to be tested for waterproof and dustproof (at least IP65)
3. Certification agencies must have an EU Notified Body

Speaking of the specific process, many novices are prone to getting stuck in the first step. Last week, a customer came to us with the technical documents he wrote. When he opened it, he saw that the circuit diagram did not even mark the voltage parameters. ​ ​These five steps must be done in regular processing​​：
① Prepare product manual, circuit diagram, and component list
② Send samples to the laboratory for a full set of tests (usually 3-5 weeks)
③ Prepare technical documents based on test reports
④ Signing a statement of conformity (DOC document)
⑤ Tie the CE mark on the product nameplate

The cost is the most tangled. There are prices in the market ranging from 8,000 to 80,000. What is the difference? To give a real case: a manufacturer is looking for a copycat institution with a cheap price, but the product was spot checked in the Netherlands and found that the brightness exceeded the standard, so he paid 200,000 euros alone. ​ ​The certification fee mainly includes​​：

• Testing fee (15,000-50,000, depending on product complexity)
• Document service fee (5,000-20,000)
• Annual maintenance fee (requires regular renewal certification)

Now the key point is - many colleagues don’t know about the tips for saving money. Last year, when we helped our customers with P3 outdoor screen certification, we found that if we replace the power module with a certified model in advance, the overall cost can be saved by 40%. ​ ​These preparations can save you money​​：
√ Select certified power supply and driver IC
√ Prepare lightning protection design in advance (eliminate later modifications)
√ Prepare a complete English instruction manual (save translation fee)

Finally, let’s talk about the most serious issue of the validity period of the certificate. Last month, an old customer came here and said that the certification he obtained three years ago suddenly failed. In fact, CE certification itself has no deadline, but​ ​In these three situations, you must re-certify​​：

1. Product structure changes (such as changing the lamp bead model)
2. EU standards update (make special attention in July every year)
3. Special requirements for the customer's country (such as France has additional regulations on color temperature)

Recently, an interesting phenomenon was discovered: more and more Southeast Asian customers are also starting to require CE certification. Although these countries do not require it, they think that having a CE standard is quality assurance. So, get this certification early and feel at ease. Instead of studying how novices can quickly increase their fans every day, we should make our display screens solid first. After all, overseas customers will not give you a second chance, so certification is really careless.
