U.S. imports of medical, surgical, dental & veterinary instruments & appliances (nesoi) (HS 901890) totaled $1.8B in July 2026, traded with 91 countries.
Importers of Medical, Surgical, Dental & Veterinary Instruments & Appliances (NESOI) paid $101.7M in duties in July 2026 — an effective duty rate of 11% on $938.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataAs a broad residual heading, 901890 captures a wide spectrum of medical and veterinary instruments — from anesthetic apparatus and electro-surgical devices to defibrillators, dialysis equipment, and sphygmomanometers — that are not classified under more specific Chapter 90 headings. Mexico and Costa Rica are the leading US supply sources, reflecting substantial nearshore medical-device manufacturing, while Germany and Ireland contribute high-value electro-medical and therapeutic equipment. All articles entering as medical devices are subject to FDA admissibility review, and electro-surgical or life-sustaining equipment may require premarket approval or 510(k) clearance. The heading's 22 active 10-digit tariff lines — spanning optical instruments, dialysis apparatus, defibrillators, and NESOI electro-medical appliances — make precise classification critical to correct duty treatment.

Yes — defibrillators have their own dedicated 10-digit line (9018906400), separate from the broader electro-surgical instruments line (9018906000). Printed circuit assemblies specifically for those defibrillators are further broken out under 9018906800. Importers should verify that the device meets the technical description for the specific line rather than defaulting to the NESOI electro-medical line.
FDA requires that the foreign manufacturer be registered and the device listed in FDA's device database. Depending on device class, a 510(k) clearance number or PMA approval must be on file. At entry, CBP may request an FDA release, and shipments may be detained for FDA examination if the device lacks proper registration or labeling. Consulting a licensed customs broker or regulatory affairs specialist before importation is strongly recommended.
