U.S. imports of dental instruments & appliances (nesoi), parts & accessories (HS 901849) totaled $62.6M in April 2026, traded with 50 countries.
Importers of Dental Instruments & Appliances (NESOI), Parts & Accessories paid $6.1M in duties in April 2026 — an effective duty rate of 10% on $60.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataDental burs, hand instruments, and other dental appliances not covered by the drill engine heading are spread across four 10-digit lines — 9018494000 (dental burs), 9018498040 (dental hand instruments and parts), 9018498080 (other instruments and appliances), and a general provision (9018490000) — making correct line selection dependent on the specific instrument type. Germany leads US imports for this heading, with China and Switzerland also significant sources; the China origin exposure means importers should assess Section 301 applicability for specific product lines. Dental burs warrant particular attention: carbide versus diamond bur construction, shank type (friction grip, latch, straight), and ISO size designation are the specification details that matter for both clinical procurement and quality compliance. All instruments intended for clinical use are subject to FDA CDRH device registration requirements.

Dental burs have a dedicated 10-digit line (9018494000) that takes precedence over the residual dental instruments line (9018498080). Importers should classify burs — whether carbide, diamond, or steel — under 9018494000 rather than the general NESOI provision. The distinction matters because duty rates and Section 301 exposure may differ by line, particularly for burs sourced from China.
Dental hand instruments are regulated as medical devices by FDA CDRH. The foreign manufacturer must be registered with FDA and the specific device listed before importation. For instruments that are substantially equivalent to a legally marketed predicate, a 510(k) clearance is typically required. Importers should also verify that the supplier maintains ISO 13485 quality system certification and that instruments meet applicable ISO or ANSI/ADA standards referenced in purchasing contracts. Consult a licensed customs broker or regulatory counsel to confirm admissibility for specific instrument types.
