The Bilateral Trade in Goods by End-Use (BTiGE) database aims at highlighting international flows of intermediate and final goods. It is based primarily on UN Comtrade annual trade statistics, supplemented where necessary by national sources and OECD Secretariat estimates. Using a correspondence table developed by the OECD, flows of products reported under different versions of the Harmonized System (the latest being HS-2022), are mapped to activities based upon the Classification of Products by Activity (CPA 2.1) and to end-use categories.
The database was designed to include balanced trade flows which, combined with national Supply-Use and Input-Output Tables, feed into the OECD’s Inter-Country Input-Output (ICIO) model, the principle source of the OECD's Trade in Value Added (TiVA) indicators.
