Product classification
HS code for Glass polishing machine: 8464.20
Machine-tools, grinding or polishing machines, for working stone, ceramics, concrete, asbestos-cement or like mineral materials or for cold working glass.
Classification of glass polishing machine under HS 8464.20
HS code 8464.20 is designated for machine-tools used for grinding or polishing glass in its cold state. This classification is part of Chapter 84, which encompasses machinery and mechanical appliances. Heading 8464 specifically covers machine-tools for working stone, ceramics, concrete, or similar mineral materials, or for the cold working of glass. The distinction of "cold working" is vital; it refers to mechanical processes like grinding, polishing, or lapping that occur after the glass has solidified and cooled. Machines that work glass in a molten or hot state (such as glass-blowing or glass-molding machines) are classified under heading 8475. Subheading 8464.20 is specific to the abrasive actions of grinding and polishing, which are essential for finishing glass edges, surfaces, or optical components. These machines must be stationary and power-driven to be considered machine-tools under this heading.

Codes often confused with 8464.20
Common mistake. The most common misclassification occurs with heading 8475, which covers machines for the hot working of glass. If the machine shapes glass while it is soft or molten, 8475 is the correct code. Another error involves 8464.10 (sawing machines) or 8464.90 (other glass working machines like drills). Users also confuse these with hand-held pneumatic or electric tools, which are classified under heading 8467 rather than the machine-tool heading 8464.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
