What does heading 8408 of the customs tariff cover?
Heading 8408 covers compression-ignition internal combustion piston engines (diesel and semi-diesel engines). It applies to engines for vehicles, construction machinery, power generators, ships, and other applications. Duty rates vary depending on application and power output. Engines must meet EU emission standards appropriate to their use (Euro VI for road vehicles, Stage V for non-road machinery). Technical documentation and certification are required. Poland is an important market for diesel engines, both as a component for domestic automotive and machinery production and as a service element for road transport. Heading 8408 is part of Chapter 84 (machinery, mechanical and electrical equipment) of the Combined Nomenclature (CN) used in the European Union. This classification is based on the Harmonized System (HS) developed by the World Customs Organization (WCO), which is used in over 200 countries worldwide. The EU Combined Nomenclature extends the HS with additional 8-digit subheadings, while the TARIC system adds 10-digit codes for identifying specific trade measures. Each 4-digit heading such as 8408 is subdivided into 6-digit (HS), 8-digit (CN) and 10-digit (TARIC) subheadings that specify the type of goods for the purpose of applying the correct duty rates, trade measures and regulatory requirements. Correct determination of the 10-digit code is essential for establishing the amount of customs duties and taxes, as well as required permits and certificates. Classification of goods under heading 8408 must follow the General Rules for the Interpretation (GRI) of the Combined Nomenclature. Rule 1 states that classification is determined primarily by the terms of the headings and the relevant section or chapter notes. The Explanatory Notes to the Harmonized System and the Combined Nomenclature clarify the scope of each heading and are essential references for importers and customs brokers.
Duty rates and import requirements for heading 8408
Duty rates vary depending on application and power output. Technical documentation and certification are required. Poland is an important market for diesel engines, both as a component for domestic automotive and machinery production and as a service element for road transport. Duty rates vary — check CN subheading based on engine power and application. Road vehicle engines must meet Euro VI/VII, non-road machinery engines must meet Stage V. Manufacturer technical documentation and EU declaration of conformity required. Import of engines for service/repair purposes — check customs clearance procedure for spare parts. When importing goods under heading 8408 into the European Union, attention must be paid to applicable duty rates, which depend on the specific subheading (8- or 10-digit code) and the country of origin. MFN (Most Favoured Nation) duty rates apply to imports from countries with which the EU does not have preferential trade agreements. Current rates can be checked in the EU TARIC database on the European Commission website. Import of goods under heading 8408 may benefit from preferential duty rates under Free Trade Agreements (FTAs) concluded by the EU with third countries, the Generalised Scheme of Preferences (GSP) for developing countries, or autonomous tariff suspensions. Claiming preferences requires presentation of appropriate proof of origin (EUR.1 certificate, origin declaration, REX certificate or statement on origin under the registered exporter system). Goods under heading 8408 are subject to CE directive compliance (Machinery, LVD, EMC, RoHS). Required documentation includes: CE declarations of conformity, operating instructions, technical documentation, EMC and LVD certificates. In addition to customs duty, imports are subject to VAT at the rate applicable in the country of destination. The VAT taxable amount at import is the customs value plus duty and any countervailing or anti-dumping duties.
Classification of goods under heading 8408 — key considerations
Heading 8408 covers compression-ignition piston engines (diesel/semi-diesel). Key: ignition by compression, not spark (8407). Engine power determines the subheading. Includes engines for trucks, construction machinery, ships, and generator sets. Common mistake: a turbocharged diesel is still 8408; the turbocharger separately is 8414.
Frequently asked questions
What EU customs duty rates apply to diesel engines under heading 8408?
Customs duty rates for compression-ignition internal combustion piston engines (diesel and semi-diesel) under heading 8408 range from 0% to 4.2% depending on power output and application. Vehicle engines carry a conventional rate of about 2.7%-3.5%. Industrial engines and generator engines may have 0%-2.7% duty. Marine engines often benefit from zero duty. Preferential rates apply for countries covered by EU trade agreements. Classification depends on the engine's power output and intended use. Current duty rates should be verified in the European Commission's TARIC database. Classification follows the Combined Nomenclature (CN) of the European Union.
What documents and certificates are required for importing diesel engines into the EU?
Importing diesel engines requires a customs declaration, commercial invoice, certificate of origin, and technical documentation. Engines must meet emission standards: Euro 6e for road vehicles, Stage V (Regulation (EU) 2016/1628) for non-road machinery, IMO Tier III for marine engines. An EU declaration of conformity and CE marking are required. Vehicle engines need ECE/UN type-approval. An engine specification sheet with power, torque, and emission data must accompany the shipment. This applies to goods classified under heading 8408 of the Combined Nomenclature. Current duty rates should be verified in the European Commission's TARIC database. Classification follows the Combined Nomenclature (CN) of the European Union.
What practical considerations apply when importing diesel engines?
When importing diesel engines, it is essential to distinguish between engines for vehicles, construction machinery, generators, and ships — each category has a separate CN subheading and specific requirements. Used engines face stricter emission controls and may require additional testing. Transporting diesel engines needs specialised logistics due to their significant weight. Consider future restrictions on combustion engines under EU climate policy. Spare parts are classified separately under heading 8409. This applies to goods classified under heading 8408 of the Combined Nomenclature. Current duty rates should be verified in the European Commission's TARIC database. Classification follows the Combined Nomenclature (CN) of the European Union.
