Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If cut/polished solely for optical instruments
Optical elements worked beyond basic glass fall in Chapter 90.
If unworked colored floated glass
Drilling/engraving constitutes 'worked' status.
If fibrous or wool-like structure
Glass wool definitions in chapter notes redirect to 7019.
