U.S. imports of dental drill engines, parts & accessories (HS 901841) totaled $6.1M in June 2026, traded with 25 countries.
Importers of Dental Drill Engines, Parts & Accessories paid $601K in duties in June 2026 — an effective duty rate of 10% on $6.0M in dutiable value, based on actual customs collections rather than the published tariff schedule. Dental Drill Engines, Parts & Accessories imports of $6.1M in June 2026 ran 18% above the year-to-date monthly average of $5.1M.
Dental drill engines — including high-speed air turbine handpieces and electric micromotor systems, whether standalone or integrated into dental unit bases — classify under a single tariff line (9018410000) and are regulated as Class II medical devices by FDA CDRH. Switzerland and Japan lead US imports for this heading, reflecting the dominance of precision Swiss and Japanese manufacturers in the high-end dental handpiece segment; Germany and Austria are also notable sources. Rotational speed (measured in RPM), torque output, drive mechanism (air turbine versus electric), and coupling system compatibility are the specification variables most critical to procurement and interoperability with existing dental unit infrastructure. Importers should confirm that handpieces meet ANSI/ADA and ISO 14457 standards, which are commonly referenced in hospital and dental group purchasing organization contracts.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes — 9018410000 covers dental drill engines whether or not combined with other dental equipment on a single base, and explicitly includes parts and accessories thereof. However, if a component is more specifically described by another heading (for example, a bearing or motor that is not dedicated to dental use), GRI rules and chapter notes may direct classification elsewhere. A binding ruling is advisable for high-value or recurring parts shipments.
Both air turbine and electric micromotor dental handpieces classify under 9018410000 — the drive mechanism does not create a separate tariff line at the 10-digit level. From an FDA regulatory standpoint, both types are Class II devices subject to 510(k) clearance, though the specific predicate device and performance standards cited in the clearance application will differ. Procurement teams should verify that the specific model's 510(k) clearance covers the intended clinical use.
