TRAINS (TRade Analysis and INformation System)  provides online access to indicators of Trade Control Measures (Tariff, Para-tariff and Non-tariff measures), as well as imports by suppliers at each Harmonized System 6-digit level for over 150 countries.

It also provides country notes of trade regimes for some 40 developing countries, describing market access conditions according to the UNCTAD Coding System of Trade Control Measures.

For more comprehensive data coverage, including time-series, UNCTAD has collaborated with the World Bank in developing  the World Integrated Trade Solution (WITS) software.

Average applied import tariff rates on non-agricultural and non-fuel products are available in the UNCTAD Handbook of Statistics.
