Indicator NameTariff rate, most favored nation, simple mean, primary products (%)
Short definitionSimple mean most favored nation tariff rate is the unweighted average of most favored nation rates for all products subject to tariffs calculated for all traded goods. Data are classified using the Harmonized System of trade at the six- or eight-digit level. Tariff line data were matched to Standard International Trade Classification (SITC) revision 3 codes to define commodity groups. Primary products are commodities classified in SITC revision 3 sections 0-4 plus division 68 (nonferrous metals).

Statistical concept and methodologyMethodology: This indicator calculates the simple (unweighted) mean of statutory most-favored-nation (MFN) tariff rates across all tariff lines for primary products. It reflects tariff rates that apply to all World Trade Organization (WTO) members on a non-discriminatory basis unless preferential agreements are in force. Simple mean most favored nation tariff rate is the unweighted average of most favored nation rates for all products subject to tariffs calculated for all traded goods. Data are classified using the Harmonized System of trade at the six- or eight-digit level. Tariff line data were matched to Standard International Trade Classification (SITC) revision 3 codes to define commodity groups. Primary products are commodities classified in SITC revision 3 sections 0-4 plus division 68 (nonferrous metals). Tariff data are primarily sourced from the World Trade Organization (WTO) Consolidated Tariff Schedules (Consolidated Tariff Schedules (CTS)) and Integrated Database (Integrated Database (IDB)), with supplementary inputs from the United Nations Conference on Trade and Development (United Nations Conference on Trade and Development (UNCTAD)). Data are submitted by national authorities using the Harmonized System (Harmonized System (HS)) classification. The WTO Secretariat validates and harmonizes submissions to a common HS version for comparability. Data are generally updated annually or as new schedules are submitted. Due to validation and alignment processes, there is typically a one- to two-year time lag between national reporting and publication. The calculation is performed by summing the MFN rates and dividing by the total number of tariff lines. No trade-based weighting is applied. Only reported rates are included, and harmonized classifications ensure comparability across countries.
