Product classification
HS code for Reinforced rubber tubing: 4009.31
Rubber, vulcanised (other than hard rubber), tubing, piping and hoses, reinforced or otherwise combined only with textile materials, without fittings.
Classification of reinforced rubber tubing under HS 4009.31
The classification of reinforced rubber tubing under HS code 4009.31 is determined by the material composition and the structural reinforcement method. According to the General Rules for the Interpretation of the Harmonized System (GRI), products are classified based on their constituent materials and their state of manufacture. Heading 4009 covers tubes, pipes, and hoses of vulcanized rubber other than hard rubber. Subheading 4009.31 specifically identifies products that are reinforced or otherwise combined only with textile materials and are presented without fittings. The "without fittings" distinction is crucial, as the addition of permanent attachments would shift the classification to 4009.32. The textile reinforcement typically consists of a braided or woven layer embedded within the rubber walls to provide structural integrity and pressure resistance. This code is used for industrial and automotive hoses where textile fibers like nylon, polyester, or aramid provide the necessary tensile strength without the weight or rigidity of metal.

Codes often confused with 4009.31
Common mistake. This code is frequently confused with HS code 4009.11, which covers rubber tubing that has no reinforcement at all. It is also often mistaken for HS code 4009.32, which applies to the same textile-reinforced tubing but includes those fitted with permanent attachments or fittings. Furthermore, if the reinforcement is made of metal rather than textile, the product must be classified under HS code 4009.21 (without fittings) or 4009.22 (with fittings).
Top exporters and importers of HS 400931 (the code used for reinforced rubber tubing), 2025
In 2025, the largest exporter of HS 400931 (the code used for reinforced rubber tubing) in UN Comtrade data was Germany, with 13% of world exports; the largest importer in UN Comtrade data was the United States, with 19% 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).
