HS v2022 Code: 700800

About glass; multiple-walled insulating units of glass

HS code 700800 covers the production and trade of multiple-walled insulating units of glass. This industry plays a crucial role in the construction and energy efficiency sectors, providing essential materials for windows, doors, and other architectural applications. As a key component of modern building design, the demand for high-performance insulating glass units continues to grow, driven by the need for improved energy efficiency and thermal comfort in both residential and commercial properties.

Production process

The production of multiple-walled insulating glass units typically involves the assembly of two or more panes of glass, separated by a sealed air or gas-filled space. This process often utilizes specialized machinery and equipment to ensure precise dimensional tolerances, airtight seals, and optimal thermal performance. Manufacturers may employ techniques such as tempering, laminating, or coating the glass to further enhance its properties, depending on the specific application requirements.

Production inputs

The main inputs for the production of multiple-walled insulating glass units include flat glass 700500 Float glass, sheet glass and the like, sealants, spacers, and various gases (e.g., argon, krypton) used to fill the interstitial spaces. Manufacturers also rely on specialized machinery and equipment, such as glass cutting and edging tools, assembly lines, and quality control systems, to ensure the consistent production of high-quality insulating glass units.

Production outputs

The primary output of HS code 700800 is multiple-walled insulating glass units, which are widely used in the construction industry for windows, doors, and other architectural applications. These insulating glass units are often consumed by industries covered under 940510 Chandeliers and other electric ceiling or wall lighting fittings, 940520 Electric table, desk, bedside or floor-standing lamps, and 940540 Other electric lamps and lighting fittings, as they play a crucial role in enhancing the energy efficiency and thermal performance of buildings.
