Subheading 400922 of the Combined Nomenclature covers tubes, pipes and hoses of vulcanised soft rubber that are reinforced with metal only and are fitted with couplings or other accessories permanently attached at the time of importation. The product must satisfy both conditions simultaneously: the hose wall is reinforced exclusively with metallic layers – steel wire braid, metallic spiral, helical coil or another metallic reinforcing insert – and at least one coupling, connector, valve or end fitting is permanently attached to the hose before importation. Fittings typically include crimped or threaded couplings made of carbon steel, stainless steel or brass, as well as integrated valves, swivel joints and flanged ends. Finished hose assemblies of subheading 400922 are widely used in hydraulic systems of construction, agricultural, mining and industrial machinery; in industrial high-pressure liquid transfer lines; in sand-blasting and shot-blasting equipment; and in diesel fuel and hydraulic oil circuits. The high pressure resistance conferred by metal reinforcement makes these assemblies suitable for applications requiring working pressures beyond the capacity of textile-reinforced hoses. The GIRs, in particular rules 1, 6 and 3(b) for composite assemblies, together with the Notes to Chapter 40 and the HS Explanatory Notes, are applied to determine the scope of this subheading.

Importation of metal-reinforced rubber hose assemblies with fittings (400922) into the EU customs territory is governed by the Union Customs Code (Regulation (EU) No 952/2013). The importer or authorised customs representative must lodge an import customs declaration in the AIS/IMPORT system, specifying the correct 10-digit TARIC code, the customs value of the complete assembly (hose and all fittings) and the country of origin. The commercial invoice should provide a detailed technical description: rubber type and compound for the inner liner and outer cover, the number and type of metallic reinforcement layers (e.g. two high-tensile steel wire braid layers, braid angle and wire diameter), dimensions (nominal internal diameter DN, external diameter, length), maximum working pressure and proof pressure, the applicable manufacturing standard for the hose (e.g. EN 853 classes 1SN/2SN, EN 856 classes 4SH/R12/R13, or ISO standards 1436, 3862) and a full description of the fittings (material, type, thread specification or coupling standard, crimping method). Finished hydraulic assemblies may fall within the scope of Regulation (EU) 2023/1230 (Machinery Directive) where supplied as part of a machine assembly, and potentially within Directive 2014/68/EU (PED) for pressure equipment applications. Fittings in stainless steel or brass may require a material declaration in accordance with EN 10204 and, where applicable, RoHS compliance. All rubber articles are subject to REACH (Regulation (EC) No 1907/2006). To benefit from preferential tariff rates under EU FTAs (CETA, EU-Japan EPA, GSP/GSP+), a valid proof of origin is required – EUR.1, invoice statement or REX registration. The importer should obtain from the manufacturer a product certificate to the applicable EN/ISO standard, a pressure test report and a REACH declaration.

Correct classification under 400922 requires both conditions to be met simultaneously: metal-only reinforcement and permanently attached fittings. The absence of either condition leads to a different subheading. Hoses with identical metal-only reinforcement but without fittings are classified under 400921 – this boundary is critical when importing hydraulic hose in lengths (sold by the metre) as opposed to finished assemblies with crimped fittings. Hoses reinforced solely with textile materials and fitted with accessories are classified under 400932; hoses reinforced solely with plastics materials and fitted – under 400942. Where the reinforcement combines metal and textile or plastics layers (e.g. a steel wire braid plus a polyester or aramid fabric layer), the correct subheading for an assembly with fittings is 400959. A common tariff error is the classification of hydraulic hose assemblies with metal fittings under Chapter 73 (pipe fittings) or Chapter 84 (machine parts) – crimped fittings are an integral part of the hose assembly and do not shift the classification to another chapter where the essential character remains the rubber hose. Where doubts arise regarding the construction of the reinforcement, the importer should obtain a technical cross-section diagram from the manufacturer identifying all construction layers. A Binding Tariff Information (BTI) decision is recommended for complex cases, providing legal certainty for three years throughout the EU.
