HS code for Metal hoses: 8307.90
Tubing, flexible, with or without fittings of base metal, other than those of iron or steel.
Classification of metal hoses under HS 8307.90
Flexible tubing of base metal, commonly referred to as metal hoses, is classified under HS code 8307.90 when the material is a base metal other than iron or steel. Heading 8307 covers flexible tubing of base metal, with or without fittings. The nomenclature splits this heading into two primary subheadings: 8307.10 for iron or steel and 8307.90 for other base metals such as aluminum, copper, or brass. These hoses are characterized by their ability to bend and flex while maintaining the protective or conductive properties of metal. They are often used for protecting electrical wiring (conduit) or for transporting fluids and gases in environments where plastic or rubber hoses would be unsuitable due to temperature or pressure requirements. The presence of end-fittings (connectors) does not change the classification under this heading, as the essential character remains that of flexible tubing. The construction usually involves spirally wound metal strips or corrugated metal tubes, sometimes covered with a braided metal wire sheath for added strength and pressure resistance.

Codes often confused with 8307.90
Common mistake. The most frequent misclassification is using HS code 8307.10, which is strictly for flexible tubing made of iron or steel. If the hose is made of rubber but reinforced with metal, it must be classified under HS code 4009. Similarly, plastic flexible tubing reinforced with metal falls under HS code 3917. If the metal hose is part of a specific machine assembly and is imported as a dedicated spare part, it might occasionally be misclassified under the machine's heading in Chapter 84, though 8307 generally takes precedence as a specific description of the article.
Top exporters and importers of HS 830790 (the code used for metal hoses), 2025
In 2025, the largest exporter of HS 830790 (the code used for metal hoses) in UN Comtrade data was China, with 15% of world exports; the largest importer in UN Comtrade data was the United States, with 16% of world imports.

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).
