HS code for ECG machine: 9018.11
Medical, surgical instruments and appliances, electro-cardiographs.
Classification of ECG machine under HS 9018.11
The ECG machine is classified under HS code 9018.11 as a specific type of electro-diagnostic apparatus used in medical science. Heading 9018 encompasses a wide array of instruments used in medical, surgical, dental, or veterinary sciences. Within this heading, the Harmonized System provides a specific 6-digit subheading (9018.11) exclusively for electro-cardiographs. This classification is based on the functional nature of the device, which records the electrical activity of the heart over a period of time using electrodes placed on the skin. Because the HS nomenclature prioritizes specific descriptions over general ones, any device whose primary function is electrocardiography must be placed here rather than in the residual "other" category of 9018.19. This applies to both stationary clinical models and portable diagnostic units.

Codes often confused with 9018.11
Common mistake. ECG machines are frequently misclassified under 9018.19, which is the general category for other electro-diagnostic apparatus. While 9018.19 includes EEG and EMG machines, the specificity of 9018.11 for ECGs takes legal precedence. They are also sometimes confused with 9027.89 (physical or chemical analysis instruments), but since ECGs are used for medical diagnosis on human subjects, Chapter 90 is the correct placement. Another error is classifying them under 9018.12, which is strictly for ultrasonic scanning equipment.
Top exporters and importers of HS 901811 (the code used for ECG machine), 2025
In 2025, the largest exporter of HS 901811 (the code used for ECG machine) in UN Comtrade data was Singapore, with 25% of world exports; the largest importer in UN Comtrade data was the United States, with 24% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
