SITCSection 7
U.S. imports of non-numerically controlled tool & cutter sharpening machines (SITC 73166) totaled $1.9M in July 2026, traded with 21 countries.
Importers of Non-Numerically Controlled Tool & Cutter Sharpening Machines paid $290K in duties in July 2026 — an effective duty rate of 16% on $1.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataManually operated tool and cutter grinding machines — used to resharpen drills, milling cutters, and similar tooling without programmable axis control — serve small machine shops, maintenance departments, and toolrooms where throughput requirements do not justify CNC investment. The absence of numerical control is the defining classification criterion separating this heading from SITC 73165. These machines are often compact bench-top or floor-standing units, and their relatively lower unit value compared to CNC equivalents makes duty rate and origin accuracy especially important for cost management.

Basic heading 73166 · $1.9M of $175.6B
Yes. Motorized or power-assisted feed mechanisms do not constitute numerical control. The machine must execute a stored numerical program governing axis positions to qualify as numerically controlled. A motorized wheel feed with manual workhead positioning remains a non-NC machine for classification purposes.
Standard metalworking machine tools do not require end-use certificates for most origins. However, if the machine has dual-use potential under Export Administration Regulations (EAR) — for example, if it meets certain precision thresholds relevant to controlled manufacturing — the importer should verify whether any import or re-export considerations apply, particularly for machines with very high accuracy specifications.
