HS Code: 700510 – Float glass and surface ground or polished glass, in sheets, having an absorbent, reflecting or non-reflecting layer, but not otherwise worked (excl. wired glass)

Float glass is essentially a super smooth, distortion-free glass which is used for designing other glass items such as laminated glass, heat-toughened glass, and so on. With a natural greenish hue and translucent nature, it is capable of transmitting about 87% of the incident light, and unlike sheet glass, float glass provides users with a crystal-clear view. Float glass owes its unique name to the process by which it is manufactured wherein the molten glass is introduced into a bath of molten tin, causing the glass to float freely.
