Last updated: April 2026 dataEdge-worked, bent, engraved, drilled, or otherwise processed glass that has not been made into safety glass or mirrors—and is not framed or fitted with other materials—occupies this heading, covering products such as shaped architectural panels, beveled glass panes, and decorative etched glass. The critical classification boundary is that the glass must be worked beyond simple cutting but must not yet be incorporated into a composite article; fitting with frames or other materials moves the product to a different heading. Precision processing tolerances and surface treatments are the specification details most relevant to buyers in the architectural and interior-design trades.

Once the glass is framed, fitted with metal hardware, or combined with other materials into a composite article, it typically moves out of this heading. The key boundary is whether the glass remains an unassembled, unfitted worked blank versus a finished or semi-finished composite product.
Curved or bent architectural glass that has been thermally or mechanically formed but is not laminated safety glass and is not yet framed or fitted generally falls within this heading. If the bending process also produces a tempered or laminated safety product, classification under the safety glass heading would take precedence.
