HS v2022 Code: 7004
About glass; drawn glass and blown glass, in sheets, whether or not having an absorbent, reflecting or non-reflecting layer, but not otherwise worked
HS code 7004 covers a critical segment of the glass manufacturing industry, encompassing the production of drawn and blown glass sheets. These materials play a vital role in a wide range of applications, from construction and automotive to electronics and consumer goods. The global glass sheet market is expected to grow steadily in the coming years, driven by increasing demand from various end-use industries and the rising need for energy-efficient building materials.
Production process
The production of glass sheets under HS code 7004 primarily involves two main techniques: drawn glass and blown glass. Drawn glass is produced by drawing molten glass through a die or slot, resulting in thin, uniform sheets. Blown glass, on the other hand, is created by blowing air into a molten glass bubble, which is then flattened into sheets. Both methods allow for the creation of glass with varying thicknesses, surface properties, and optical characteristics, depending on the specific requirements of the end-use application.
Production inputs
The key inputs for the production of glass sheets under HS code 7004 include raw materials such as silica sand, soda ash, and limestone, as well as specialized equipment like glass-drawing machines and annealing ovens. Additionally, the industry relies on a skilled workforce capable of operating the production equipment and maintaining quality control standards. Energy sources, such as natural gas or electricity, are also essential for melting and shaping the glass.
Production outputs
The primary outputs of the glass sheet industry covered by HS code 7004 are various types of drawn and blown glass sheets, which can be used in a wide range of applications. These glass sheets may be further processed, coated, or laminated to meet specific requirements. Some of the industries that consume the output of HS code 7004 include 7005 Float glass and surface ground or polished glass, in sheets, but not otherwise worked, 7006 Glass of heading 7003, 7004 or 7005, bent, edge-worked, engraved, drilled, enamelled or otherwise worked, but not framed or fitted with other materials, and 7007 (Safety glass, consisting of toughened (tempered) or laminated glass).
