How to Identify the Production Date of Fuyao Glass?

[MacCharlotte]

Each piece of glass produced by Fuyao is marked with its production date. For example, ..8, where 8 represents the year, indicating it was produced in 2008. The dots represent the month. Dots before the number signify the first half of the year, while dots after signify the second half. The number of dots indicates how many months forward or backward from the midpoint of the year. If the dots are before the number, subtract the number of dots from 7; if after, subtract from 13. ..8 correctly means the glass was produced in May 2008. Below is an introduction to the Fuyao Glass brand: 1. Background: Fuyao Glass is the largest automotive glass manufacturer in China, with the highest technology, largest export volume, and largest scale in the domestic market.

I recently helped a friend inspect a car and studied the date markings on Fuyao glass - it's quite simple. Look for a black square or a string of numbers with dots in the corner of the glass. For example, '8...' means August 2018. Note that the small dots before the number indicate the year by subtracting their quantity from 7, while dots after represent the month. If you see something like 'D1△24', the 'D' stands for manufacturer, '1' is the month, '△' is the production line code, and '24' is the year. The coding system changes across different years - before 2018 they used numbers and dots, while in recent years letters plus numbers became more common. The markings are clearest when viewed in sunlight after washing the car, but never scratch the coded area with hard objects.

First-hand method for replacing Fuyao windshield: First locate the LIS logo at the bottom left or right corner, resembling an 'FY+' symbol. The date code is usually adjacent to it, either as dotted number combinations like '..7' indicating July 2023 (dots = 7 - quantity), or in formats like 'FY0433'—where the first two digits '03' in the last four represent March, and the last two '23' denote the year. EV glass may have an additional 'E' mark. Key reminder: When replacing glass in winter, thoroughly clean the edges as codes become extremely hard to read when frozen, and prevent de-icer from corroding the printed codes.

An old mechanic at the repair shop taught me a simple trick: use your phone's flashlight to check the edges of the glass. Date codes are usually hidden near the black ceramic border. For example, seeing '8••' means February 2018 (dots in front indicate the second half of the year, two dots mean 8-6=2 months). Newer models have codes like 'LAM15-2', where '15' before the hyphen is the 15th week, and '2' stands for 2022. Pay attention to letter combinations—'E' at the start means it's an export version, and 'T' is for trucks. If the code is worn, don't use a paint marker to trace it, as this can affect the annual inspection.

Anyone in the auto parts business knows that Fuyao dates have undergone three generations of changes. After 2020, the common format is letter + number, such as 'D3'. D represents the month (A to M excluding I), and 3 represents the last digit of the year 2023. The older style uses numbers with dots, like '19..': the two dots on the right = April 2019 (19 + 1 = 2020? Wrong! This is a trap—the dot on the left actually indicates the year). The trickiest is the version before 2014, where the dot position determines the first or second half of the year. Here's a tip: check the black dot in the supplier code—a solid dot indicates genuine Fuyao factory parts.

Essential Checks for Used Car Glass Inspection: First, locate the ten-digit characters near the FY mark. The 5th to 8th digits are the most critical—for example, GM8322 indicates the 38th week of 2022. For glass without letters, observe the dot pattern: five dots after a number signify July (12 months divided into five groups, each representing a specific month range). When replacing glass, always verify the UV transmittance parameter—windshields must have over 70% to comply. Reminder for owners: Avoid checking the date immediately after heavy rain, as watermarks can make the dot matrix appear to have an extra dot, leading to misjudgment as the next year.
