Which document you need and why
Certificate or declaration where applicable; high-voltage and passive-equipment exclusions checked
CU TR 004 is considered within its voltage range, with the assessment form determined by use and product lists. CU TR 020 does not automatically apply to every transformer: passive equipment without active electronics must be checked against exclusions, and equipment outside CU TR 004 cannot be documented under it merely for import. Electronic components, supplied power units and special functions require configuration-specific assessment; one tariff code does not determine all documents.
What to send for a quotation
Start with these four items. If something is missing, send what you have and we will explain what else is needed.
Product name
Name, model, intended use and manufacturer.
HS / EAEU commodity code
Include the code if known. If not, we can help identify the product.
Technical description
Specifications, photographs, instructions or a product datasheet.
Composition and materials
Ingredients, materials or a component specification, depending on the product.
Provide winding diagrams, primary and secondary voltages, rating, frequency, cooling, insulation class and installation conditions. Identify electronic controls, protection, enclosure and oil, intended equipment or network use, and series or batch supply.
Which requirements we check
- Voltage scope
- Intended and independent use
- Dielectric strength and insulation distances
- Heating, cooling and load rating
- EMC testing need for electronics
- Winding and terminal marking and installation instructions
