Auto Glass Bugs
This slide show has images of what we call in the auto glass industry "Bugs" which
are labels imprinted or etched into the glass. They are typically located in the
lower center or one of the corners of the glass. Bugs show the name of the auto
glass manufacturer, date code and color codes that are proprietary information with
each company. Another item that is located on the Bug is the DOT. This stands for
Department of Transportation. Each auto glass manufacturer is assigned a number that
indicates where the glass was made. The last company that touches the glass is
typically the one that will place their Bug onto the auto glass. For example, if a
windshield is made without a molding, it may be sent to another location to be
applied and that facility will use their DOT number.

Today, we are seeing more USA auto glass companies hiring or partnering with
Chinese auto glass manufacturers. On the Bug, there will be the USA OEM brand name
but the DOT will indicate that the manufacturer was actually a Chinese company.
Chinese glass manufacturers are making glass fit a lot better now than in the past.
Several good examples are Benson and XYG (Xinyi). In these slides, we are showing
two companies PGW (also know as PPG) and AP Tech. Both are using the same Chinese
manufacturer with DOT 563 (SHENZHEN AUTOMOTIVE GLASS MANUFACTURING) located in
Guangdong province, China.
