Classification of stone saw under HS 8464.10
Stone saws are classified under HS code 846410. This heading covers machine-tools for sawing stone, ceramics, concrete, or glass. These machines are characterized by their ability to cut through hard mineral substances using blades, wires, or abrasive discs. The classification is specific to stationary or semi-stationary machinery used in workshops or quarries for the primary cutting of stone blocks or slabs. Under the Harmonized System, sawing is distinguished from grinding or polishing, leading to the specific sub-categorization at the six-digit level. The classification process involves evaluating the machine's design and intended use. If the machine is a large-scale bridge saw used for cutting granite slabs to size, it fits perfectly within 846410. However, if the saw is a small, hand-held device with an integrated electric motor, it would likely be classified under 846722. The distinction rests on the machine-tool definition, which usually requires the machine to be fixed in place during operation. Furthermore, the material being worked must be a mineral substance; saws for wood or metal are classified under 8465 or 8461, respectively. This code is essential for the stone fabrication industry, ensuring that heavy-duty cutting equipment is correctly identified for tariff and trade purposes.

Codes often confused with 8464.10
Common mistake. Stone saws are often confused with hand-held power saws under 846722. The key difference is that 846410 applies to machine-tools that are stationary or mounted. Another misclassification is 8465, which is reserved for wood-working saws. Saws for metal-working fall under 846150.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. 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).
