PRODCOM is the title of the EU production statistics for Mining, Quarrying and Manufacturing that comes from the French title "PRODuction COMmunautaire" (Community production). PRODCOM headings are directly derived from NACE and the CPA. The first four digits of a PRODCOM code refer to the NACE classification, and the first six digits refer to the CPA classification. The last two digits are created specifically for PRODCOM. Most eight-digit PRODCOM codes have a complete reference to the Combined Nomenclature (CN) that means a full comparability between data from PRODCOM and data from foreign trade classified by the Combined Nomenclature.
