Electrical transformers, static converters (for example, rectifiers) and inductors

Heading 8504 covers electrical transformers, static converters (e.g. rectifiers, inverters), and inductors. It applies to power transformers, power supplies, chargers, UPS systems, and voltage converters. Duty rates vary by device type and power rating. Products must comply with LVD and EMC directives and CE marking. Power transformers are subject to the Ecodesign Regulation on minimum efficiency. Heading 8504 is part of Chapter 85 (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 8504 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 8504 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 vary by device type and power rating. Products must comply with LVD and EMC directives and CE marking. Poland imports significant quantities of transformers and power supplies for energy infrastructure expansion, renewable energy development, and the industrial sector. Domestic transformer production also plays an important role. Duty rates vary - check CN subheading based on device type and power rating. CE marking and LVD, EMC directive compliance required. Power transformers subject to ecodesign minimum efficiency requirements (Tier 2). PV inverters and EV chargers may qualify for reduced rates - check CN subheading. When importing goods under heading 8504 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 8504 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).

Heading 8504 covers electrical transformers, static converters (rectifiers, inverters, UPS), and inductors. Key: changing current parameters (voltage, frequency, AC/DC conversion). Computer power supplies are 8504. Phone chargers belong here. Common mistake: mechanical voltage stabilizers are 9032, not 8504.
