U.S. imports of sawing machines for stone, ceramics & similar mineral materials (HS 846410) totaled $8.5M in August 2026, imported from 30 countries.
Importers of Sawing Machines for Stone, Ceramics & Similar Mineral Materials paid $1.4M in duties in August 2026, an effective tariff rate of 15.96% of the $8.5M imported — duty actually collected as a share of that value, not the published tariff schedule.
Last updated: August 2026 dataSawing machines for stone, ceramics, concrete, asbestos-cement, and cold glass working — including bridge saws, wire saws, and tile-cutting machines — enter the US under a single 10-digit line (8464100100), simplifying classification but not eliminating the need to confirm the machine's intended substrate. China leads US imports of this equipment, followed by Italy and Vietnam, reflecting both high-volume Chinese production of tile and stone saws and Italy's premium natural-stone processing machinery. These machines are central to the countertop fabrication, tile installation, and monument industries, where diamond-blade technology and CNC cutting tables have become standard. Importers sourcing from China should assess Section 301 tariff exposure, which applies to this equipment.

A bridge saw designed specifically for cutting stone or ceramic materials classifies under 846410 regardless of whether it incorporates CNC controls, because the HS gives priority to the specific material-working function (stone/ceramic sawing) over the control technology. The single US 10-digit line 8464100100 covers all such sawing machines without a separate N/C breakout.
The heading description includes asbestos-cement as a workable substrate, but importers should be aware that asbestos-containing materials are subject to EPA import restrictions under the Toxic Substances Control Act. The machine itself — a saw designed to cut such materials — is not restricted, but any accompanying asbestos-cement test pieces or samples would require separate regulatory review.
