Inverters with power over 7.5 kVA
This code covers static converters that are inverters and have a power rating over 7.5 kVA. The key distinction is that the power must be over 7.5 kVA.
For example
- A power inverter with a power rating over 7.5 kVA
- An industrial inverter with a power rating over 7.5 kVA

Before you use the code
Check the facts that sit outside the code
The code can be right while what you pay still changes, because of where the goods come from, when they arrive, or extra EU measures.
- The product and its form Check that your product really matches this description, including what it is made of and the form it arrives in.
- Country of origin Trade agreements, sanctions and extra measures can change the treatment of the very same code.
- Current tariff measures Check today's rate, any restrictions or licences, and the quantity customs asks for, with Toldstyrelsen or TARIC.
Rates, origin and documents
Read the signals first. Open only the ones you want to check.
Besides the ordinary duty, the EU records these kinds of measure against this code. They are listed as signals only: whether one applies to your goods can depend on where they come from, who produced them, the exact product and the documents you present. No amounts are worked out here.

Restrictions and paperwork
Important
Import restrictions are recorded for goods originating in:
- North Korea (Democratic People’s Republic of Korea)
- Ukraine

The EU records document conditions on this code. What customs may ask for depends on where the goods come from, exactly what the product is and the customs procedure.
Proof of origin 2 conditions
If you claim a lower rate for goods from a country the EU has a trade agreement with, customs asks for proof of origin, for example a EUR.1 certificate or an origin declaration.
Show the EU's own wording for these conditions
- Invoice declaration or origin declaration made out by any exporter on invoice or any other commercial document
- Movement certificate EUR.1
Sanctions and restricted regions 12 conditions
Some conditions come from EU sanctions rules. They matter when the goods are linked to a country or region the EU restricts trade with.
Show the EU's own wording for these conditions
