HS Code 40.09 – Tubes, pipes and hoses, of vulcanised rubber (other than hard rubber), with or without their fittings (e.g. joints, elbows, flanges)

HS code 4009 is a 4-digit heading in the Harmonized System that covers: Tubes, pipes and hoses, of vulcanised rubber (other than hard rubber), with or without their fittings (e.g. joints, elbows, flanges). Heading 4009 specifically covers tubes, pipes, and hoses made of vulcanised rubber, excluding hard rubber, and notably includes those with or without their fittings. This classification is fundamental for international trade as these products are critical for conveying liquids, gases, and sometimes solids across virtually every industrial, commercial, and domestic sector. The 'vulcanised rubber' characteristic ensures durability, flexibility, and resistance to pressure, temperature, and chemicals, making them superior to many plastic alternatives for demanding applications. The inclusion of 'with or without their fittings' simplifies classification, preventing the need to separate hoses from their attached joints, elbows, or flanges. Key applications range from automotive coolant and fuel lines, industrial hydraulic and air hoses, to construction, agricultural, and general-purpose water hoses. The boundary 'other than hard rubber' is crucial, differentiating these flexible products from the rigid pipes of heading 4017. Accurate classification is paramount for trade compliance, ensuring correct duty assessments, adherence to safety standards (e.g., for automotive or medical uses), and avoiding regulatory hurdles. This heading underscores Chapter 40's comprehensive coverage of rubber products, highlighting the specialized role of vulcanised rubber in fluid and gas handling systems globally.

Automotive coolant hoses, hydraulic hoses (without fittings), industrial air hoses, rubber fuel lines, radiator hoses, garden hoses (rubber), vacuum cleaner hoses (rubber), fire hoses (rubber inner lining), chemical transfer hoses, oil-resistant rubber pipes, marine exhaust hoses, flexible rubber ducts, pharmaceutical grade rubber tubing, braided rubber hoses, reinforced rubber pipes, irrigation hoses (rubber), brake fluid hoses (rubber), rubber tubing for medical devices, suction hoses (rubber), discharge hoses (rubber), rubber pipe bends with fittings, rubber hose assemblies with flanges, rubber expansion joints (hose-like), rubber turbocharger hoses, rubber heater hoses, rubber air intake hoses, rubber drain pipes, rubber ventilation hoses

Common misclassifications involve confusing 4009 with plastic tubes, pipes, and hoses (3917) or with specific parts of machinery or vehicles (e.g., 8487 or 8708). The key distinction for 4009 is the material: 'vulcanised rubber' and 'other than hard rubber.' If the hose is clearly identifiable as a part or accessory solely or principally used with a specific type of machine or vehicle (e.g., a highly specialized automotive hose designed only for a particular car model), it might be classified under the relevant machinery or vehicle chapter (e.g., 8708 for automotive parts). However, general-purpose hoses, even if used in these applications, typically remain under 4009. The 'with or without fittings' clause is also critical, as it ensures the entire assembly is classified together. Incorrect classification can lead to disparate duty rates and compliance challenges, especially when dealing with product-specific regulations for safety or environmental standards.

In 2025, the top exporters of HS code 4009 in UN Comtrade data were China ($1.7B, 13% of world exports), Germany ($1.2B) and the United States ($1.2B). World exports came to about $13.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 4009 in UN Comtrade data were the United States ($2.4B, 18% of world imports), Germany ($1.1B) and Mexico ($734M). World imports came to about $13.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 4009 is a 4-digit heading under Chapter 40 of the Harmonized System. The first 2 digits (40) identify the chapter, and digits 3-4 (09) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
