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 in the manufacturing of vehicles, aircraft, spacecraft, and vessels. This specialized type of glass is designed to provide enhanced protection and safety features, making it an essential material in the transportation and aerospace industries. As a key input for various high-value products, the production and trade of laminated safety glass plays a significant role in the global economy.

Production process

The production of laminated safety glass involves a multi-step process. First, two or more layers of glass are bonded together using a transparent plastic interlayer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This interlayer acts as a shock-absorbing and shatter-resistant component. The glass layers are then subjected to heat and pressure, creating a strong, durable, and optically clear laminated glass panel.

Production inputs

The main inputs required for the production of laminated safety glass 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, advanced manufacturing techniques, and strict quality control measures to ensure the safety and reliability of the final product.

Production outputs

Laminated safety glass produced under HS code 700721 is primarily used in the manufacturing of 870321 passenger cars, 880240 aircraft, 890190 vessels, and 950699 spacecraft. The output of this industry is a critical component for these high-value transportation and aerospace products, contributing to their overall safety and performance.
