Classification of marine steam turbines (8406 10)

Subheading 8406 10 of the Combined Nomenclature covers steam turbines for the propulsion of marine vessels and warships. Marine steam turbines convert thermal energy of steam into mechanical energy driving the propeller shaft through a reduction gearbox. They are used on LNG carriers (using boil-off gas as boiler fuel), older-generation tankers, warships (especially nuclear-powered: aircraft carriers, submarines, cruisers), and nuclear icebreakers. Modern marine turbines achieve outputs from several to tens of MW. The key classification criterion is the intended marine propulsion use, distinguishing from stationary turbines for electricity generation (8406 81/82). Marine turbines are subject to specific requirements for resistance to marine conditions, vibrations, and vessel inclinations. Classification follows GRI rules 1 and 6. Parts for steam turbines are classified under 8406 90.

Maritime regulations and import requirements for marine turbines

Marine steam turbines under subheading 8406 10 are subject to maritime regulations of the International Maritime Organisation (IMO). The SOLAS Convention sets safety requirements for machinery installations on ships. Classification societies (Lloyd's Register, DNV, Bureau Veritas, ABS) certify marine turbines in accordance with their technical rules. Directive 2014/90/EU on marine equipment (MED) may apply to turbines on vessels flying EU Member State flags, requiring wheelmark marking. The Machinery Regulation (EU) 2023/1230 does not apply to marine equipment subject to MED. Import requires an EORI number, customs declaration, and classification society certificate. Turbines for warships may be subject to dual-use controls. Documentation includes type certificate, technical specification, and factory test report.

Customs duties and the marine turbine market (8406 10)

MFN duty rates for marine steam turbines under subheading 8406 10 should be verified in TARIC. The marine steam turbine market is a niche market dominated by a few manufacturers from Japan (Mitsubishi, Kawasaki), Korea (Doosan), and Europe. Steam turbines on LNG carriers compete with dual-fuel DFDE engines. Preferential rates may be available under FTA agreements. Chapter 84 products are not subject to CBAM. The customs value includes the cost of the turbine with reduction gearbox and control system. Import VAT is charged. Current rates should be verified in TARIC.

Frequently asked questions

Which vessels use steam turbines classified under 8406 10?
Marine steam turbines are used on LNG carriers (utilising boil-off gas as boiler fuel), older-generation tankers, warships (especially nuclear-powered: aircraft carriers, submarines, cruisers), and nuclear icebreakers. On modern merchant vessels, steam turbines are gradually being replaced by dual-fuel engines, but they remain in use on LNG carriers due to their ability to burn boil-off gas.
Are marine turbines subject to the Marine Equipment Directive MED?
Yes. Steam turbines installed on vessels flying EU Member State flags are subject to Directive 2014/90/EU (MED) on marine equipment, provided they are listed in the annex to the implementing regulation. MED requires wheelmark marking and conformity assessment by a notified body. Classification societies (DNV, Lloyd's, BV) serve as certifying bodies. Turbines for vessels flying non-EU flags are subject to flag state regulations.
Are turbines for warships subject to dual-use controls?
Steam turbines for warships may be subject to export control as military products under the EU Common Military List (category ML10 - warships and marine engines). Dual-use Regulation (EU) 2021/821 may apply to dual-use technologies. Import of military turbines requires authorisation from the export control authority. Trade in military equipment is subject to restrictions from EU embargoes and sanctions.
