OECD 2010

This document addresses some re-allocation issues for discussing possible improvements in the quality and use of time series in the International Trade by Commodity Statistics (ITCS) database. Also, it reports on the current availability of data in the database. It presents the main methodological issues faced after two years of data collection and dissemination of the HS2007 classification. It sets out the “inflation” of some commodity codes and important breaks in historical HS classifications.
