Initially, Market Access Map HS6 (MAcMap-HS6) was a database jointly developed by the International Trade Centre (ITC, Geneva) and the CEPII, for years 2001, 2004 and 2007.  It provides  a comprehensive measure of bilateral tariffs (through ad valorem equivalents of the tariff protection) applied by 190 importing countries to 220 exporting countries, on 5,113 products at the 6 digit level of the Harmonized System (see Guimbard et al, 2012). Applied tariffs take account of trade preferences applied by each importer and of all regional agreements in which it is involved (see Bouët et al, 2008). It also contains the tariffs applied under the Most-Favored-Nation clause (MFN) by the members of the World Trade Organization.
 
For countries’ profiles, MAcMap-HS6 2013 v1.0 is built using raw data coming from ITC. However, as information is not yet available, for products subject to tariff rate quotas, the 2007 rates are used. Therefore, the protection actually applied on these products is potentially different, but this is a useful first approximation.
Previous version MAcMap-HS6 (for years 2001, 2004 and 2007) are available on CEPII’s website: http://www.cepii.fr/CEPII/fr/bdd_modele/presentation.asp?id=12
