Glass; safety glass, laminated, (not of a size and shape suitable for incorporation in vehicles, aircraft, spacecraft or vessels)

HS code 700729 covers the classification of laminated safety glass that is not suitable for use in vehicles, aircraft, spacecraft, or vessels. This type of glass is commonly used in various architectural and construction applications, providing enhanced safety and security features compared to standard glass. The production and trade of this specialized glass product play a crucial role in the broader construction and building materials industry, catering to the needs of both commercial and residential projects.

The production of laminated safety glass under HS code 700729 typically involves a multi-step process. First, two or more layers of glass are bonded together using a transparent plastic interlayer, such as polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This interlayer acts as a binding agent and helps to hold the glass layers together, even if the glass is shattered. The laminated glass is then subjected to heat and pressure to ensure a strong and durable bond between the layers. Finally, the finished product is cut and shaped to the desired specifications, ensuring compliance with the size and shape requirements outlined in the code.

The main inputs required for the production of laminated safety glass under HS code 700729 include high-quality float glass, plastic interlayer materials (such as PVB or EVA), and specialized machinery for the lamination process. Additionally, the industry relies on a skilled workforce capable of operating the production equipment and ensuring the quality and consistency of the final product. Energy sources, such as electricity or natural gas, are also essential for powering the manufacturing facilities and heating the glass during the lamination process.

The primary output of HS code 700729 is laminated safety glass, which is used in a variety of architectural and construction applications, including windows, doors, and partitions. This type of glass is valued for its enhanced safety features, as it is designed to remain intact and prevent shattering upon impact or breakage. The output of this industry may be consumed by other HS codes, such as 940510 Chandeliers and other electric ceiling or wall lighting fittings, 940600 Prefabricated buildings, and 940510 Furniture; wooden, where the laminated safety glass is incorporated into the final products.
