U.S. imports of machine tools for working stone, ceramics, concrete & glass (nesoi) (HS 846490) totaled $11.8M in August 2026, imported from 33 countries.
Importers of Machine Tools for Working Stone, Ceramics, Concrete & Glass (NESOI) paid $1.5M in duties in August 2026, an effective tariff rate of 12.57% of the $11.8M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataCovering operations beyond grinding and polishing — such as cutting, splitting, and shaping — these machine tools serve the natural stone, tile, glass fabrication, and precast concrete industries. The heading divides into glass-working machines excluding grinding or polishing (8464900110) and machines for stone or like mineral materials not elsewhere specified (8464900120). Italy and Germany are the leading suppliers to the US market, with China a significant third source; Chinese-origin equipment is subject to Section 301 tariffs, making origin documentation a routine compliance step.

Heading 846420 is limited to grinding and polishing machines. Heading 846490 (NESOI) captures all other machine-tool operations on stone, ceramics, concrete, asbestos-cement, and similar mineral materials, or for cold working glass — including cutting, sawing, splitting, and shaping machines that do not fit the grinding/polishing description. If a machine performs multiple functions, classification typically follows its principal function.
Customs will look to the manufacturer's technical specification sheet, sales literature, and any CE or industry certification identifying the machine's designed workpiece. For the glass-working line (8464900110), documentation should confirm the machine is engineered for cold working glass; for the mineral-materials line (8464900120), it should identify the specific substrate — stone, ceramic, concrete, etc. A binding ruling from CBP can provide certainty when a machine is marketed for multiple substrates.
