HS Code 90.20 – Breathing appliances and gas masks; excluding protective masks having neither mechanical parts nor replaceable filters and excluding apparatus of item no. 9019.20
What HS 90.20 covers
Heading 9020 specifically covers breathing appliances and gas masks, playing a critical role in personal safety, industrial protection, and emergency response. This classification encompasses devices designed to provide breathable air or filter contaminants from the air, crucial for survival in hazardous environments. Examples include self-contained breathing apparatus (SCBA) used by firefighters, industrial gas masks for chemical protection, and military-grade respirators. It is important to note the explicit exclusions: protective masks having neither mechanical parts nor replaceable filters (e.g., simple surgical masks or dust masks, often classified in 6307.90 or 3926) and apparatus of item no. 9019.20, which refers to therapeutic respiration apparatus like medical ventilators. This distinction is vital for accurate customs classification, ensuring proper duty assessment and compliance with safety standards and import/export controls, especially for dual-use items. The heading reflects the advanced engineering required for life-support and protective respiratory systems, aligning with Section XVIII's focus on precision and specialized instruments. The trade significance of these items is particularly highlighted during public health crises or industrial accidents, where demand can surge dramatically.

- Examples
A Swedish company exports advanced Self-Contained Breathing Apparatus (SCBA) units to fire departments and rescue services in Australia and New Zealand, ensuring compliance with strict safety standards. Concurrently, a Chinese manufacturer supplies industrial gas masks and full-face respirators with interchangeable filters to mining operations and manufacturing plants across South America, typically shipped in bulk via sea freight. Furthermore, a U.S. defense contractor exports specialized CBRN (Chemical, Biological, Radiological, and Nuclear) masks to allied military forces in various European countries, often requiring secure, expedited air cargo.
Subheadings under 90.20 1
Codes often confused with 90.20
Common mistake. The most common misclassification for 9020 involves confusing complex breathing appliances with simpler protective masks. Disposable surgical masks or basic dust masks without mechanical parts or replaceable filters are explicitly excluded and typically fall under 6307.90 (other made up articles) or 3926 (other articles of plastics). Another error is classifying therapeutic respiration apparatus, such as CPAP machines or medical ventilators, which belong to 9019, under 9020. The key distinction is 'protection/safety' (9020) versus 'therapy/treatment' (9019) or 'simple barrier' (6307/3926). Misclassifying can lead to incorrect duties, non-compliance with safety regulations, and potential import/export restrictions on controlled items.
Top exporters and importers of HS code 9020, 2025
In 2025, the largest exporter of HS code 9020 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).
