Of an output exceeding 375 kVA but not exceeding 750 kVA
Scope of subheading 850163 - AC generators 375 to 750 kVA
Subheading 850163 of the Combined Nomenclature covers alternating current generators with an apparent power exceeding 375 kVA but not exceeding 750 kVA. Generators in this range are industrial-class units designed to power large facilities: shopping centres, office complexes, clinical hospitals, Tier II/III data centres, large manufacturing plants and water treatment stations. An output of 375–750 kVA corresponds to active power of approximately 300–600 kW (at cos φ = 0.8). Typical designs are three-phase synchronous generators with automatic voltage regulator (AVR) and brushless excitation systems. Generators in this class are driven by diesel engines, gas engines or water turbines. Classification requires confirmation of apparent power above 375 kVA up to 750 kVA. Generators up to 375 kVA fall under 850162, above 750 kVA under 850164. Classification follows GRI rules 1 and 6.
Import regulations for AC generators 375–750 kVA
Importing AC generators under subheading 850163 requires a customs declaration with EORI number and correct CN code. The LVD Directive (2014/35/EU) applies to generators rated 50–1000 V AC. The Machinery Regulation (EU) 2023/1230 covers complete generating sets. The EMC Directive (2014/30/EU) covers electromagnetic emissions. Generators intended for parallel operation with the power grid are subject to network code requirements, particularly Regulation (EU) 2016/631 on requirements for generators. IEC 60034 and ISO 8528 define technical parameters. Marine generators require classification society certification. CBAM does not apply to generators from Chapter 85. Transport requires logistics planning due to weight of 1–3 tonnes. Documentation: commercial invoice, technical specification, declaration of conformity, transport document.
Customs duties and trade in AC generators 375–750 kVA
MFN duty rates for AC generators under subheading 850163 should be verified in TARIC. Preferential rates available under FTAs require compliance with rules of origin and proof of origin. Generators rated 375–750 kVA are imported mainly from specialised manufacturers in China, India, Italy, Germany and the USA. Growing demand for reliable emergency power for data centres and critical infrastructure drives the market for generators in this power class. Importers should check TARIC for current trade measures. Imports from EU-sanctioned countries are subject to restrictions. VAT is charged on import. TARIC codes should be verified before clearance.
Import requirements for generators 8501 63
Electric generators under CN 8501 63 are used in conventional and renewable energy. MFN duty: 2.7%. Import requires a CE declaration (LVD + EMC). Wind turbine generators face additional requirements under Machinery Regulation (EU) 2023/1230. Customs value includes transport costs to the EU border.
Frequently asked questions
What is the difference between a 375 kVA and 375 kW generator?
Apparent power of 375 kVA includes both active power (kW) and reactive power (kvar). Active power in kW depends on the power factor cos φ of the load: at cos φ = 0.8, a 375 kVA generator delivers approximately 300 kW of active power. Customs classification of AC generators is based on apparent power in kVA, not active power in kW. Correct determination of power in kVA from the nameplate is critical for classification: 375 kVA still falls under 850162, above 375 kVA falls under 850163.
Can AC generators 375–750 kVA operate in parallel with the grid?
Yes, synchronous generators can operate in parallel with the public power grid, but this requires compliance with network code requirements, particularly Regulation (EU) 2016/631 on requirements for generators. The generator must be equipped with synchronisation systems, anti-islanding protection and active/reactive power regulation. The distribution system operator may impose additional technical requirements. Duty rates should be verified in TARIC.
What certifications are required for marine generators under subheading 850163?
AC generators intended for marine applications (ships, drilling platforms) require certification from an international classification society such as Lloyd's Register, DNV GL, Bureau Veritas, ClassNK or American Bureau of Shipping. Certification covers compliance with IEC 60034, IEC 60092 (electrical installations in ships) and classification rules concerning vibration resistance, moisture and marine corrosion. Classification society certification is required for registering the generator on a vessel.
What ecodesign requirements apply to motors under 8501 63?
Motors under CN 8501 63 are subject to Regulation (EU) 2019/1781. Three-phase motors must meet IE3 or IE4 efficiency class depending on power and market placement date.
