HS Code 84.75 – Machines; for assembling electric or electronic lamps, tubes, valves, flashbulbs, in glass envelopes, machines for manufacturing or hot working glass or glassware

HS code 8475 is a 4-digit heading in the Harmonized System that covers: Machines; for assembling electric or electronic lamps, tubes, valves, flashbulbs, in glass envelopes, machines for manufacturing or hot working glass or glassware. Heading 8475 encompasses highly specialized industrial machinery designed for two primary functions: the manufacturing or hot working of glass or glassware, and the assembly of specific electric or electronic components within glass envelopes. This includes a vast array of equipment used in industries ranging from lighting and electronics to pharmaceuticals and construction. The scope covers processes that involve significant transformation of glass through heat, such as melting, blowing, forming, tempering, and annealing, as well as the intricate assembly of items like lamps, tubes, valves, and flashbulbs where glass is the primary encapsulation material. Key sub-categories include machines for producing bottles, ampoules, optical fibers, glass tubes, and specialized furnaces for glass treatment. This classification is vital for trade compliance as these are high-value capital goods, often subject to specific duties, import licenses, and technical regulations. Proper classification ensures accurate duty assessment, avoids penalties, and facilitates the smooth flow of critical manufacturing equipment globally. Historically, the evolution of machinery in this heading reflects major advancements in materials science and automated manufacturing, making it central to the production of essential goods requiring precise glass components. It stands as a specific application within Chapter 84, which broadly covers machinery and mechanical appliances, focusing on a unique material and its transformation.

Glass bottle manufacturing machines, optical fiber drawing towers, ampoule forming machines, incandescent lamp assembly machines, fluorescent tube sealing machines, glass tempering furnaces, glass bending machines, glass melting furnaces, pharmaceutical vial production machines, glass bulb blowing machines, vacuum tube sealing machines, flashbulb manufacturing lines, laboratory glassware forming machines, glass tube drawing machines, cathode ray tube (CRT) production lines, glass fiber spinning machines, insulating glass unit assembly lines (hot process), LED encapsulation machines (glass), glass pressing machines (hot), glass grinding machines (hot work), glass annealing kilns, glass polishing machines (hot work), glass preform stretching machines, glass furnace feeders, glass container decorating machines (hot applied).

Traders often misclassify machinery under this heading by confusing it with general-purpose equipment or machines for cold working glass. A common mistake is classifying glass cutting or grinding machines (cold processes) under 8475, when they typically belong to 8464 (Machinery for working stone, ceramics, concrete, or glass in the cold). Similarly, generic industrial furnaces might be incorrectly placed here instead of 8417 (Industrial or laboratory furnaces and ovens, non-electric), unless they are specifically designed for glass manufacturing processes like tempering or melting. Another error involves packaging machines (8422) if they only fill or seal pre-made glass containers, rather than manufacturing or hot-working the glass itself. The key distinction for 8475 lies in the primary function of manufacturing, hot working, or assembling components within glass envelopes.

In 2025, the top exporters of HS code 8475 in UN Comtrade data were Singapore ($887M, 20% of world exports), Japan ($541M) and Germany ($536M). World exports came to about $4.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 8475 in UN Comtrade data were Singapore ($595M, 15% of world imports), Taiwan (about $546M) and Belgium ($312M). World imports came to about $4.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 8475 is a 4-digit heading under Chapter 84 of the Harmonized System. The first 2 digits (84) identify the chapter, and digits 3-4 (75) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
