Fused Quartz Glass Slab
>- Rectangular slab of fused quartz glass in bulk mass form, ideal for slicing into substrates or windows in photonics applications. It qualifies as unworked glass in the mass of fused silica, where cutting to shape does not affect classification.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the slab is cast or rolled into sheets
Cast or rolled glass sheets fall under heading 70.03.
If the slab is worked (e.g., polished or edged)
Worked glass of heading 70.06 remains there even if it has the character of an article.

Import Tips & Compliance
• >- Note that cutting to shape does not make the glass "worked" per Chapter 70 Note 2(b), but any polishing or coating would
• Keep the slab in its raw, unpolished state to stay under this item
• Provide a detailed product description to the CBSA to avoid misclassification

Architectural Glass Melt Lumps
>- Lumps of melt from architectural flat glass production, unworked for remelt. These are glass in the mass, other than fused quartz, prior to sheet forming.
Borosilicate Glass Chunks
>- Massive chunks of borosilicate glass, known for thermal resistance, in unworked form straight from the melting furnace. This is other glass in the mass, used as raw material for labware and cookware.
Colored Soda Glass Masses
>- Soda glass in mass with integrated colorants like cobalt for blue tint, unworked. Classified as other glass in the mass, with color from the melt rather than surface treatment.
Container Soda Glass Billets
>- Soda glass billets in mass form for remelting into bottles and jars, unworked and amorphous. This is other glass in the mass, excluding scrap or activated types.
Electric-Fused Quartz Mass
>- A bulk mass of quartz glass produced by electric arc fusion, known for low bubble content in high-end applications. This is glass in the mass of fused quartz, unworked and not yet shaped or processed into articles.
Flame-Polished Fused Silica Mass
>- Fused silica in mass form with flame-polished surfaces to minimize defects, used in fiber optic preform production. The flame polishing is a pre-annealing process, so the glass remains unworked and classifiable as glass in the mass.
