HS code for Oxygen therapy machine: 9019.20

Therapeutic respiration apparatus, ozone, oxygen, aerosol therapy apparatus, artificial respiration or other therapeutic respiration apparatus.

Classification of oxygen therapy machine under HS 9019.20

Oxygen therapy machines are classified under HS code 9019.20. This classification falls under Chapter 90, which covers medical and surgical instruments. Heading 9019 specifically includes mechano-therapy appliances, massage apparatus, and psychological aptitude-testing apparatus, as well as ozone therapy, oxygen therapy, aerosol therapy, artificial respiration, or other therapeutic respiration apparatus. The classification of oxygen therapy machines under 9019.20 is based on the device's primary function of providing therapeutic treatment to the respiratory system. This includes devices that concentrate oxygen from the ambient air (oxygen concentrators) and those that deliver oxygen or air under pressure to assist breathing, such as ventilators or CPAP machines. The classification is determined by GRI 1 and the specific language of subheading 9019.20. These devices are considered active medical devices because they rely on an external source of power to function and are designed to change the physiological state of the patient. The WCO Explanatory Notes clarify that this heading includes apparatus used for the treatment of respiratory diseases or for the administration of oxygen in cases of emergency. It is essential to distinguish these from simple masks or tubing, which might be classified as accessories under 9018 or 9019 depending on their complexity and use.

Codes often confused with 9019.20

Common mistake. These machines are often confused with HS code 9018.90, which is a general category for other medical instruments and appliances. However, 9019.20 is more specific for respiratory therapy. Another common misclassification is 8421.39, which covers filtering or purifying machinery for gases. While an oxygen concentrator filters air, its primary purpose is medical therapy, making Chapter 90 more appropriate than Chapter 84. Protective gas masks without mechanical parts are classified under 9020.00.

Top exporters and importers of HS 901920 (the code used for oxygen therapy machine), 2025

In 2025, the largest exporter of HS 901920 (the code used for oxygen therapy machine) in UN Comtrade data was Singapore, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 37% 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).
