総務省｜統計基準等｜日本標準商品分類（平成2年6月改定）

This page explains Japan's Standard Commodity Classification (revised June 1990) published by the Ministry of Internal Affairs and Communications. It clarifies the distinction from product classification, stating that the commodity classification covers only tangible, movable goods traded in markets. Intangible assets, services, land, and buildings are excluded. The page notes this is a classification for statistical presentation, not individual commodity certification. It provides links to detailed classification tables and documents for various commodity categories including raw materials, processed materials, and production equipment.
