HS Code 4009.12 – Rubber; vulcanised (other than hard rubber), tubing, piping and hoses, not reinforced or otherwise combined with other materials, with fittings
HS code 4009.12 is the 6-digit subheading for rubber, vulcanised (other than hard rubber), tubing, piping and hoses, not reinforced or otherwise combined with other materials, with fittings. It is used for silicone hose assemblies with fittings, EPDM tubing with connectors, natural rubber pipe with flanges, SBR hose with quick-connects and medical rubber tubing sets.
What HS 4009.12 covers
This HS code covers vulcanised rubber tubing, piping, and hoses that are not reinforced or combined with other materials, but *include fittings*. The addition of fittings makes these products ready-to-use assemblies, simplifying installation and ensuring secure connections in various fluid and gas transfer systems. These pre-assembled rubber conduits are crucial in industries such as automotive, plumbing, medical, and general machinery. Major exporters typically include countries with advanced rubber processing and assembly capabilities, such as China, Germany, and the United States, which produce a wide range of these fitted rubber hoses. Importers are often end-users or distributors globally, particularly in regions with strong industrial and automotive sectors like the EU, North America, and Asia, seeking complete solutions. Key trade considerations include the specific rubber compound, inner diameter, wall thickness, pressure rating, type of fittings (e.g., brass, stainless steel), and compliance with industry standards for specific applications.

Codes often confused with 4009.12
Common mistake. This code is often confused with 400911 (without fittings) or 400922 (reinforced with metal, with fittings), as the key distinction is the presence of fittings and absence of reinforcement.
Top exporters and importers of HS code 400912, 2025
In 2025, the largest exporter of HS code 400912 in UN Comtrade data was China, with 18% of world exports; the largest importer in UN Comtrade data was the United States, with 26% 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 marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
