The car front windshield accessories market is relatively chaotic, and there is no distinction between genuine and fake ones for the time being. The only difference is the brand. Moreover, most of the methods for identifying front windshields are destructive experiments, such as penetration resistance, human head model experiments, stress tests, etc. Generally, only building materials inspection and verification centers are qualified for verification. However, as long as high-end cars like Audi are replaced at a 4S store, they will be original parts and there will be no quality issues (the "Fuyao" brand's auto glass with the best quality in the country is marked with "FY"). The problem is that there will be counterfeit products on the market. The following methods can help you identify: 1. Look at the printing. The black surface of the genuine product is very smooth and shiny; the defective product is gray and has a rough feel; 2. Look at the trademark, the genuine trademark font is clear and neat; the defective product has a clear and neat font. There is a blur; 3. Check the 3C certification number and E43 European body certification number online. The 3C number will have the words E000*** in the trademark. Write down this string of characters and search online to see the manufacturer and manufacturer. Did the seller agree with what they said when you bought it? The same goes for E43. There is a string of characters below E43 in the trademark. Search online and check whether it is consistent with what the merchant said. If both characters match, it can basically be determined to be authentic. If you still don’t understand anything, please send an email to: Professional automotive glass manufacturer
