SITC is a classification of the commodities being subject to international trade. It was designed to help provide a categorization needed for economic analysis, facilitate the international comparison of trade data and offer clear categories to impose tariffs and duties. A single numeral represents a major category (e.g. 1 for Beverages & Tobacco), and each subsequent numeral represents a sub-classification that can reach up to five numerals. For instance, Wine (1121) is a subcategory of Alcoholic Beverages (112), which is a subcategory of Beverages (11). The classification is regularly revised to take account of new product categories.
