Multicellular or foam glass; in blocks, panels, plates, shells or similar forms; paving blocks, slabs, bricks and other articles of pressed or moulded glass

HS code 701690 covers a diverse range of glass products, including multicellular or foam glass, as well as various pressed or molded glass articles such as paving blocks, slabs, and bricks. These specialized glass products play a crucial role in the construction, insulation, and architectural industries, contributing to the overall efficiency and sustainability of modern buildings and infrastructure.

The production of the items covered under HS code 701690 typically involves a combination of glass manufacturing techniques, including pressing, molding, and foaming. Multicellular or foam glass is created by introducing gas bubbles into molten glass, resulting in a lightweight, insulating material. Paving blocks, slabs, and bricks, on the other hand, are produced by pressing or molding glass into the desired shapes and sizes, often with specific surface textures or patterns.

The main inputs required for the production of the goods under HS code 701690 include raw glass materials, such as silica sand, soda ash, and limestone, as well as specialized additives and foaming agents. Additionally, the industry relies on advanced manufacturing equipment, including glass melting furnaces, molds, and pressing machines, to ensure the consistent quality and precision of the final products.

The outputs of the HS code 701690 industry are primarily used in the construction and building materials sectors, where they are incorporated into various architectural and insulation applications. The multicellular or foam glass products are often used as thermal and acoustic insulation materials, while the pressed or molded glass articles, such as paving blocks and bricks, are utilized in the construction of roads, sidewalks, and other outdoor surfaces. The outputs of this industry may also be consumed by 701911 Spiderwebs, of glass fibre and 701919 Glass fibre, other than slivers, rovings, yarn or chopped strands manufacturers, who may use these specialized glass products as inputs for their own production processes.
