Combined Nomenclature (CN)
What is a CN Code?
CN stands for Combined Nomenclature. It is the common nomenclature of the European Community and is an 8-digit product classification system used in export declarations and in statistical declarations for trade in the European Community. All products and goods exported from the European Union or imported into European Union must be classified for Customs purposed. Every product will be assigned to a particular product classification code. Changes to the nomenclature occur every year and are updated and reflected into the nomenclature at the beginning of the following year.
The CN is comprised of the Harmonized System (HS) nomenclature with further Community subdivisions.

The CN code is subdivided into a hierarchal, 8 digit code structure followed by a description. The categories at the highest levels are called Sections, followed by Chapter, Sub-Chapter, Heading, and Subheadings. The first 6 digits relate to the harmonized system nomenclature and the last 2 digits relate to the CN subheadings.
