This document is written for those who wish to contribute to the GTAP data base, whether by providing an input-output table for a country not separately represented in the data base, or by updating the table for a region that is already represented. It provides specifications and advice on the structure of the table, sectoral classification, treatment of imports, and other key points. It also describes what we at the Center for Global Trade Analysis do once we receive your table.

This version has been revised for use by contributors to release 5 of the GTAP data base. In particular, all concordances are to the revised GTAP sectoral classification developed for release 5.
