U.S. imports of tool & cutter sharpening machines, not numerically controlled, metal removing (HS 846039) totaled $1.9M in April 2026, traded with 20 countries.
Importers of Tool & Cutter Sharpening Machines, Not Numerically Controlled, Metal Removing paid $302K in duties in April 2026 — an effective duty rate of 16% on $1.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataConventional tool and cutter grinding machines — manually operated or with basic mechanical control — serve toolrooms, regrind services, and smaller machining operations where the economics of NC control are not justified by volume. The United Kingdom and Germany are the leading US import sources, with China also a notable supplier. The US schedule divides this heading by condition and value: used machines (8460390010), new machines valued under $3,025 (8460390020), and new machines valued over $3,025 (8460390050). The value-based split at the 10-digit level is a classification detail that requires accurate invoice valuation at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The threshold applies to the customs value of each individual machine unit as declared on the commercial invoice. If a single machine's customs value is below $3,025, it is classified under 8460390020; at or above that value, it falls under 8460390050. Importers should ensure the invoice reflects the per-unit value accurately, particularly for multi-unit shipments, to avoid misclassification.
A bench-top machine designed specifically for sharpening cutting tools and meeting the 'not numerically controlled' criterion can be classified under 846039, provided it is designed for metal removal and tool sharpening rather than general abrasive finishing. Machines that are primarily handheld or that function as bench grinders for general use may be classified differently in Chapter 84 or Chapter 85. The machine's design purpose and technical specifications are the determining factors.
