U.S. imports of electrocardiographs (ecg machines), parts and accessories (HS 901811) totaled $28.2M in July 2026, traded with 40 countries.
Importers of Electrocardiographs (ECG Machines), Parts and Accessories paid $1.3M in duties in July 2026 — an effective duty rate of 12% on $11.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataElectrocardiographs — devices that record the electrical activity of the heart for diagnostic purposes — are regulated as medical devices by the FDA under the Federal Food, Drug, and Cosmetic Act, and importers must ensure that each model has received the appropriate 510(k) clearance or equivalent authorization before entry. The US schedule separates complete ECG units (9018113000), printed circuit assemblies (9018116000), and two categories of parts and accessories (9018118000 and 9018119000), a granularity relevant to OEM supply chains that import subassemblies separately from finished devices. Canada is the leading source for US imports under this heading, with Switzerland and Mexico also significant suppliers — a pattern consistent with the global concentration of cardiac diagnostics manufacturing among established medical device producers. Classification disputes most commonly arise when determining whether a cardiac monitoring module is a complete electrocardiograph or a part thereof.

Electrocardiographs are Class II medical devices regulated by FDA's Center for Devices and Radiological Health (CDRH). Importers must ensure the device has received 510(k) clearance or qualifies for an exemption, that the foreign manufacturer is registered with FDA, and that the device is listed in FDA's device database. At entry, FDA may detain shipments for examination if the device lacks proper clearance documentation. Consult a licensed customs broker or regulatory affairs specialist familiar with FDA device import requirements before shipping.
Printed circuit assemblies that are identifiable as suitable for use solely or principally in electrocardiographs are classified under the dedicated line 9018116000 rather than as general electronic assemblies under Chapter 85. The key test is specificity of design: a PCB engineered to process ECG signals and interface with ECG display hardware belongs here. A general-purpose microcontroller board that happens to be installed in an ECG machine would more likely classify under Chapter 85. Manufacturer documentation establishing the assembly's intended use is critical evidence.
