Product classification
HS code for Metal reinforced rubber hose: 4009.21
Rubber, vulcanised (other than hard rubber), tubing, piping and hoses, reinforced or otherwise combined only with metal, without fittings.
Classification of metal reinforced rubber hose under HS 4009.21
The classification of metal reinforced rubber hoses falls under HS code 4009.21. Chapter 40 of the Harmonized System covers rubber and articles thereof. Heading 4009 is dedicated to tubes, pipes, and hoses of vulcanized rubber other than hard rubber. The subheading 4009.21 specifically identifies hoses that are reinforced or otherwise combined only with metal. The "only with metal" designation means that no other reinforcing materials, such as textiles or plastics, are present in the structure. Furthermore, the suffix ".21" indicates that the hose is presented without fittings (such as nozzles, couplings, or flanges). These hoses are engineered for high-pressure applications where the strength of the metal reinforcement prevents the rubber from bursting or collapsing. The reinforcement usually takes the form of a wire braid, spiral, or mesh embedded within the rubber layers. If the hose contains any textile reinforcement in addition to the metal, it would be classified under 4009.41.

Codes often confused with 4009.21
Common mistake. This code is often confused with 4009.22, which covers the same metal-reinforced hoses but with fittings attached. It is also confused with 4009.11 (hoses not reinforced) and 4009.31 (hoses reinforced with textiles). If the hose is made of hard rubber (ebonite), it is classified under 4017. If the hose is primarily made of metal (e.g., flexible steel tubing), it falls under 8307.
Top exporters and importers of HS 400921 (the code used for metal reinforced rubber hose), 2025
In 2025, the largest exporter of HS 400921 (the code used for metal reinforced rubber hose) in UN Comtrade data was China, with 21% of world exports; the largest importer in UN Comtrade data was the United States, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.
Figures cover everything classified under HS 400921, not only metal reinforced rubber hose.

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).
