HS Code 8464.20 – Machine-tools; grinding or polishing machines, for working stone, ceramics, concrete, asbestos-cement or like mineral materials or for cold working glass
HS code 8464.20 is the 6-digit subheading for machine-tools, grinding or polishing machines, for working stone, ceramics, concrete, asbestos-cement or like mineral materials or for cold working glass. It is used for stone polishing machines, tile grinding machines, concrete floor grinders, glass edge polishing machines and CNC grinding machines for stone.
What HS 8464.20 covers
This category includes grinding and polishing machines tailored for finishing hard, brittle materials such as stone, ceramics, concrete, asbestos-cement, and for cold working glass. These machines are crucial for achieving precise dimensions, smooth surfaces, and aesthetic finishes in architectural, construction, and optical industries. They utilize abrasive tools and often incorporate advanced control systems for high-quality results, ranging from large-scale slab polishing to intricate glass edge finishing. Exporters are typically specialized machinery manufacturers, and importers are industries focused on high-quality surface finishing of these materials for both functional and decorative purposes.

Codes often confused with 8464.20
Common mistake. Often confused with grinding machines for metal (8460) due to similar operation, but the material being worked (stone, ceramics, glass) is the key differentiator. Also, can be confused with sawing machines (846410) if the primary function is not clearly grinding or polishing.

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).
