Product classification

HS code for High pressure plastic hose: 3917.31

Plastics, tubes, pipes and hoses thereof, flexible, having a minimum burst pressure of 27.6MPa.

Classification of high pressure plastic hose under HS 3917.31

High pressure plastic hoses are classified under HS code 3917.31. This classification is determined by the material composition (plastics of Chapter 39) and the specific technical performance of the product. To qualify for this code, the hose must be flexible and possess a minimum burst pressure of 27.6 MPa (approximately 4,000 PSI). The Harmonized System distinguishes between rigid tubes and flexible hoses; 3917.31 is reserved for flexible products that meet this high-pressure threshold. These hoses are typically reinforced with textile or metal materials to withstand extreme internal pressures while maintaining the chemical properties of the plastic polymer. The classification follows GRI 1, which prioritizes the heading description for tubes, pipes, and hoses, and the specific subheading criteria for burst pressure.

Codes often confused with 3917.31

Common mistake. The most common misclassification occurs with rubber hoses, which are classified under heading 4009. Even if a rubber hose has a high burst pressure, it belongs in Chapter 40, not 39. Another error involves flexible plastic hoses that do not meet the 27.6 MPa burst pressure requirement; these are classified under 3917.32 (not reinforced) or 3917.39 (other). Furthermore, rigid plastic pipes are classified under 3917.21 through 3917.29 depending on the specific polymer used, regardless of their pressure rating.

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).
