Standard Industrial Classification TOL 2025 (to be complemented)

The Standard Industrial Classification TOL 2025 is the data collection and description framework of statistics describing economic activities. It is used in statistics describing different areas of the economy, such as production and employment, and in national accounts statistics.

The Standard Industrial Classification is formed of five hierarchical levels: I. The character level to which main groups indicated with a character code belong II. The 2-digit level, the groups belonging to which are indicated with a 2-digit code. III. The 3-digit level, the groups belonging to which are indicated with a 3-digit code. IV. The 4-digit level, the groups belonging to which are indicated with a 4-digit code. V. The national 5-digit level, the groups belonging to which are indicated with a 5-digit code. TOL 2025 complies with NACE Rev. 2.1 on the 1 to 4-digit levels. The 5-digit level has been defined nationally based on Finland's own needs.

TOL 2025 is based on the EU's classification of economic activities NACE. In their official statistics, the EU Member States have to use NACE or a national version based on it, which is what TOL 2025 is. NACE is, in turn, derived from the UN’s International Standard Classification of All Economic Activities (ISIC). Groups on all NACE levels are defined so that they are either uniform with ISIC groups or so that the ISIC group is a combination of NACE sub-divisions, so the corresponding ISIC groups can always be combined from NACE 3-digit and 4-digit level groups. The main groups and 2-digit levels are totally uniform, but further divisions have been made in NACE to many ISIC groups on the 3 and 4-digit levels. Other classifications belonging to the harmonised entity of economic classifications are: - CN: EU:n ulkomaankaupassa käytettävä tavaranimikkeistö (Combined Nomenclature).
