Final code reached
Iron or steel sandwich panels with an insulating middle layer
This is a complete 8-digit customs code. Exports and Intrastat use it as it is. For an import into the EU the declaration uses 7308 90 51 00: this code with 00 added.
This covers double plates of iron or steel with an insulating middle layer, used as construction products. The product must be a sandwich panel of this type, rather than another iron or steel construction part.
For example
- Iron or steel sandwich wall panel with an insulating middle layer
- Iron or steel sandwich roof panel with an insulating middle layer

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.
