ISIC — International Standard Industrial Classification Rev.4
United Nations Statistics Division · 2008
Global reference classification for productive activities. Adopted by the UN Statistical Commission. JSIC aligns with ISIC at the Section and Division levels for international comparability.
JSIC relation: Aligned — JSIC Sections A–T correspond to ISIC Sections A–U. Divisions (2-digit) are mostly harmonised. Japan-specific subdivisions exist for national precision.
NAICS — North American Industry Classification System 2022
US OMB / Statistics Canada / INEGI (Mexico) · 2022
Industry classification used by the United States, Canada, and Mexico. Six-digit codes covering 20 sectors with production-oriented grouping.

NACE — Statistical Classification of Economic Activities in the European Community Rev.2.1
Eurostat · 2023
EU standard industry classification. Four-level hierarchy identical in structure to ISIC at the top two levels, with EU-specific detail.

ISCO — International Standard Classification of Occupations ISCO-08
International Labour Organization · 2008
Global framework for organising jobs into clearly defined sets of occupations. Four-level hierarchy with 10 major groups.

Comprehensive goods-and-services product classification. Five-level hierarchy covering transportable goods, non-transportable goods, and services.
JSIC relation: Related — 生産物分類 (Japan Product Classification 2024) is the Japanese counterpart. Both serve as product detail layers linking to industry classifications.
