Electrocardiographs (ECG Machines), Parts and Accessories

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.
