HS Code 9018.19 – Medical, surgical instruments and appliances; electro-diagnostic apparatus (including apparatus for functional exploratory examination or for checking physiological parameters), n.e.c. in item no. 9018.1
HS code 9018.19 is the 6-digit subheading for medical, surgical instruments and appliances, electro-diagnostic apparatus (including apparatus for functional exploratory examination or for checking physiological parameters), n.e.c. in item no. 9018.1. It is used for electrocardiographs (ECG/EKG), electroencephalographs (EEG), electromyographs (EMG), patient monitors and polysomnographs.
What HS 9018.19 covers
This category covers a broad range of electro-diagnostic apparatus used for functional exploratory examination or checking physiological parameters, not specifically covered elsewhere in 9018.1. This includes devices that measure electrical activity in the body, vital for diagnosing neurological, cardiac, and muscular conditions. Importers and exporters typically include medical device manufacturers, hospitals, clinics, and specialized distributors. The trade is characterized by continuous innovation, with devices becoming more portable, precise, and integrated with digital health platforms. Factors influencing trade include technological advancements, healthcare expenditure, and regulatory compliance. These instruments are essential for routine diagnostics and specialized medical fields, reflecting a global demand for advanced, non-invasive diagnostic capabilities across diverse healthcare settings.

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).
