HS v2022 Code: 7011

About glass envelopes (including bulbs and tubes), open and glass parts thereof, without fittings, for electric lamps and light sources, cathode-ray tubes or the like

HS code 7011 covers a crucial component in the production of various lighting and electronic devices - glass envelopes, bulbs, and tubes. These glass parts are essential for the functioning of electric lamps, light sources, cathode-ray tubes, and other similar products. This industry plays a vital role in the broader manufacturing and electronics sectors, providing the necessary glass components that enable the production of a wide range of consumer and industrial goods.

Production process

The production of glass envelopes, bulbs, and tubes involves several key steps. First, raw materials such as silica, soda ash, and other minerals are carefully measured and melted at high temperatures to create the molten glass. The molten glass is then formed into the desired shapes, such as tubes or bulbs, using techniques like blowing, pressing, or drawing. After shaping, the glass components undergo annealing, a controlled cooling process that enhances their strength and durability. Finally, the glass parts are inspected, packaged, and prepared for distribution to manufacturers in the lighting, electronics, and other related industries.

Production inputs

The main inputs required for the production of HS code 7011 items include high-purity silica sand, soda ash, limestone, and other mineral additives. Specialized machinery, such as glass-blowing equipment, annealing ovens, and precision cutting tools, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce capable of operating the specialized equipment and ensuring consistent quality control.

Production outputs

The primary outputs of the HS code 7011 industry are glass envelopes, bulbs, and tubes that are used in the production of 8539 Electric filament or discharge lamps, including sealed beam lamp units and ultraviolet or infra-red lamps; arc-lamps, 8540 Thermionic, cold cathode or photo-cathode valves and tubes (for example, vacuum or vapour or gas filled valves and tubes, mercury arc rectifying valves and tubes, cathode-ray tubes, television camera tubes, and other lighting and electronic devices. These glass components are crucial inputs for manufacturers in the lighting, electronics, and telecommunications sectors.
