Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If etched or marked for specific thickness grading
Cover glasses with graduations or special markings are calibrated glassware.
If imported as drawn glass strips before final cutting
Paving blocks or drawn glass in strips remain in heading 7006 until cut to cover glass size.
If float glass process with absorbent coating
Cover glasses with reflecting layers for optical enhancement fall under float glass sheets.
