HS code for EMG machine: 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.

Classification of EMG machine under HS 9018.19

The classification of Electromyography (EMG) machines under HS code 9018.19 is determined by their primary function as electro-diagnostic apparatus used in medical, surgical, dental, or veterinary sciences. Specifically, these devices are designed to monitor and analyze the electrical activity produced by skeletal muscles. Within the Harmonized System, heading 9018 covers a wide range of medical instruments, and subheading 9018.19 acts as a residual category for electro-diagnostic equipment that does not fall under more specific subheadings like electrocardiographs (9018.11) or ultrasonic scanning apparatus (9018.12). The classification relies on the device's capability to perform functional exploratory examinations or check physiological parameters. Because EMG machines utilize electrodes to detect neuromuscular signals and translate them into data for clinical diagnosis, they are strictly categorized here. This includes both stationary clinical units and portable diagnostic devices used for field studies or bedside evaluations. The technical nature of the equipment, involving sophisticated electronic sensors and signal processing units, places it firmly within the 9018.19 category, ensuring it is distinguished from non-electronic surgical tools or general hospital furniture.

Codes often confused with 9018.19

Common mistake. EMG machines are frequently confused with HS code 9018.11, which is reserved exclusively for electrocardiographs (ECG/EKG). While both are electro-diagnostic, they monitor different physiological systems. Another common error is 9018.12, which covers ultrasonic scanning apparatus. Importers also mistakenly use 9019.10, which covers mechano-therapy or massage apparatus, particularly when the EMG device is part of a biofeedback system used for physical therapy rather than pure diagnosis.

Top exporters and importers of HS 901819 (the code used for EMG machine), 2025

In 2025, the largest exporter of HS 901819 (the code used for EMG machine) in UN Comtrade data was the United States, with 25% of world exports; the largest importer in UN Comtrade data was the United States, with 28% 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).

Questions about EMG machine

What is the HS code for EMG machine?

The HS code for EMG machine is 901819 (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). The standard HS code for an EMG machine is 9018.19, which covers other electro-diagnostic apparatus not specified in earlier subheadings.

How do I classify EMG machine for customs?

EMG machine is classified under HS code 901819 — 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. This is a 6-digit subheading level code.

Can EMG electrodes be classified separately?

Yes, if imported separately, specialized electrodes may sometimes be classified under 9018.90 as parts and accessories, though they often follow the main machine's classification if shipped together.

Which countries are the top exporters of EMG machine (HS 901819)?

In 2025, the top exporters of HS 901819 (the code used for EMG machine) in UN Comtrade data were the United States ($5.3B, 25% of world exports), Germany ($2.8B) and the Netherlands ($2.1B). World exports came to about $21.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
