About glass; safety glass, laminated, of size and shape suitable for incorporation in vehicles, aircraft, spacecraft or vessels
HS code 700721 covers the classification of laminated safety glass, a critical component used in the manufacturing of vehicles, aircraft, spacecraft, and vessels. This specialized type of glass is designed to provide enhanced safety and protection in the event of impact or breakage, making it an essential material for the transportation industry. The global market for laminated safety glass has experienced steady growth in recent years, driven by increasing demand from the automotive, aerospace, and marine sectors as safety regulations and consumer preferences continue to evolve.
Production process
The production of laminated safety glass involves a multi-step process. First, two or more layers of glass are bonded together using an intermediate plastic or resin layer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This lamination process creates a strong, shatter-resistant material that can withstand significant impact without shattering into sharp, dangerous fragments. The glass sheets are then cut and shaped to the desired size and specifications for their intended application, ensuring a precise fit within the final product.
Production inputs
The primary raw materials required for the production of laminated safety glass are flat glass sheets, plastic or resin interlayers, and various adhesives and sealants. Manufacturers also rely on specialized machinery and equipment, such as glass cutting and shaping tools, lamination presses, and quality control systems, to ensure the consistent production of high-quality safety glass. Additionally, the industry requires a skilled workforce capable of operating the production equipment and adhering to strict safety and quality standards.
Production outputs
Laminated safety glass produced under HS code 700721 is primarily used in the manufacturing of 870321 passenger cars, 880240 aircraft, 890120 ships, and 950699 spacecraft. The glass panels are integrated into the design of these transportation vehicles to provide enhanced protection for passengers and crew. The output of this industry is also consumed by 701990 other glass products, as the laminated safety glass may be further processed or incorporated into a variety of other glass-based products.
