Product classification
HS code for Gas masks: 9020.00
Breathing appliances and gas masks, excluding protective masks having neither mechanical parts nor replaceable filters and excluding apparatus of item no. 9019.20.
Classification of gas masks under HS 9020.00
Gas masks are classified under HS code 9020.00 because they represent sophisticated breathing appliances designed to protect the wearer from inhaling hazardous gases, vapors, or particulate matter. Unlike simple protective masks, these devices incorporate mechanical components or replaceable filters, which are the defining characteristics for this specific heading. The classification is determined by the complexity of the filtration system and the presence of valves or other mechanical assemblies that facilitate respiration in contaminated environments. This code specifically excludes therapeutic respiration apparatus used in medical settings, which are categorized elsewhere. The Harmonized System distinguishes between personal protective equipment (PPE) that provides a physical barrier and those that actively filter or supply air through mechanical means. To qualify for 9020.00, the mask must either have mechanical parts (such as valves for inhalation and exhalation) or be designed to use replaceable filter cartridges. Simple paper or fabric masks that lack these features do not meet the criteria for this classification.

Codes often confused with 9020.00
Common mistake. Gas masks are frequently confused with HS code 6307.90, which covers simple textile face masks. The distinction lies in the presence of mechanical parts or replaceable filters; if a mask is merely a fabric barrier, it belongs in 6307. Another common error is 9019.20, which is reserved for ozone therapy, oxygen therapy, or aerosol therapy apparatus. While both involve breathing, 9019 is for medical treatment, whereas 9020 is for protection or life support in hostile environments.
Top exporters and importers of HS 902000 (the code used for gas masks), 2025
In 2025, the largest exporter of HS 902000 (the code used for gas masks) in UN Comtrade data was the United States, with 23% of world exports; the largest importer in UN Comtrade data was the United States, with 11% 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).
