Product classification
HS code for 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 reinforced rubber hose under HS 4009.21
Reinforced rubber hoses are classified under HS code 4009.21. This classification falls within Chapter 40, which governs rubber and rubber articles. Heading 4009 is dedicated to tubes, pipes, and hoses of vulcanized rubber other than hard rubber. The specific subheading 4009.21 is applied when the rubber hose is reinforced or otherwise combined only with metal. A critical requirement for this code is that the hose must be presented without fittings. The reinforcement typically consists of a metal wire braid, spiral, or mesh embedded within the rubber walls to provide structural integrity and high-pressure resistance. According to the Chapter 40 notes, "vulcanized rubber" refers to rubber that has undergone a chemical change (vulcanization) to make it less plastic and more elastic. The exclusion of "fittings" means the hose is usually sold in bulk lengths or cut to size without attached couplings, flanges, or connectors. If the reinforcement includes textiles or other materials in addition to metal, the classification would shift to a different subheading within 4009.

Codes often confused with 4009.21
Common mistake. The most common misclassification is HS code 4009.22, which is used when the metal-reinforced hose includes fittings. Another frequent error is 4009.11, which applies to hoses that are not reinforced at all. If the hose is reinforced with textile materials instead of metal, it should be classified under 4009.31. Confusing rubber with plastic (Chapter 39) is also a common mistake in industrial applications.
Top exporters and importers of HS 400921 (the code used for reinforced rubber hose), 2025
In 2025, the largest exporter of HS 400921 (the code used for 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.

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).
