U.S. to Investigate Imports of Float Glass from China and Malaysia
Estimated reading time: 3–5 minutes
The United States International Trade Commission (USITC) has announced the schedule for the final phase of its investigation into float glass products imported from China and Malaysia. The investigation will determine if these imports are harming the U.S. industry or threatening to harm it in the future.
What Products Are Being Investigated
The investigation covers float glass products made by floating molten glass over a bath of tin, cooling it, and then cutting it to size. These products must be at least 2.0 mm thick and have a surface area of at least 0.37 square meters. They can be clear, colored, or coated, such as Low-E glass or mirror stock. Some glass used in shower doors, laminated glass, insulating glass units, and LED mirrors are also included.
Glass is still covered even if further worked—such as cut, drilled, or curved—as long as it meets original standards and is first made in China or Malaysia.
What Products Are Not Included
Certain kinds of glass are not included. These exclusions are:
- Wired glass, greenhouse glass, and patterned solar glass
- Safety glass for vehicles
- Vacuum insulating glass units
- Framed mirrors without LEDs
- Unframed over-the-door mirrors ready for use
- Smaller washing machine lid glass
- Some solar glass with specific features
- Metal-camed glass if the parts are already excluded
- Any glass covered by other existing trade orders, such as aluminum extrusions from China
Background and Rules
The U.S. Department of Commerce had made preliminary findings that float glass from China and Malaysia was subsidized and sold below fair value. The petitions for the investigation were filed by Vitro Flat Glass, LLC and Vitro Meadville Flat Glass, LLC.

Certain information in the investigation may be confidential and handled under a protective order. Parties who had access before do not need to reapply.
