Intrastat commodity codes, also known as Combined Nomenclature (CN) codes, are a standardized classification system used to identify and categorize goods traded between European Union (EU) member states. With a few notable exceptions, the criteria of these codes are the same in all EU member states.

Each commodity or product is assigned a unique Intrastat commodity code based on the European Union's integrated classification system. The codes consist of a series of digits that represent different levels of classification, starting from the broadest categories and becoming more specific as the digits progress.

Intrastat commodity codes provide a common language for classifying goods and enable accurate data collection and reporting on the international trade of goods between EU member states. They are used to identify the type of goods being traded, allowing customs authorities and statistical agencies to gather information on imports and exports.

These codes are essential for businesses engaged in cross-border trade within the EU as they are required to provide Intrastat declarations, reporting the value and quantity of goods moved between member states. By using the correct Intrastat commodity codes, businesses ensure that their trade data is classified accurately and can be used for statistical analysis and economic monitoring at both national and EU levels.
