DATA CONCEPTS and CLASSIFICATIONS



Classification used

Weighted average: In order to aggregate tariff value for country groups it is recommended to make use of a weighting methodology based on the value of goods imported.

Tariffs: Tariffs are customs duties on merchandise imports, levied either on an ad valorem basis (percentage of value) or on a specific basis (e.g. $7 per 100 kg). Tariffs can be used to create a price advantage for similar locally-produced goods and for raising government revenues. Trade remedy measures and taxes are not considered to be tariffs.

Disaggregation

is by product sector (e.g. Agriculture, Textile, Environmental goods), geographical regions and country income level (e.g. Developed, Developing, LDCs).

Key statistical concepts

In order to include all tariffs into the calculation, some rates which are not expressed in ad valorem form (e.g., specific duties) are converted in ad valorem equivalents (i.e. in per cent of the import value), The conversion is made at the tariff line level for each importer by using the unit value method. Import unit values are calculated from import values and quantities. Only a limited number of non-ad valorem tariff rates (i.e. technical duties) cannot be provided with ad valorem equivalents (AVE) and are excluded from the calculation. This methodology also allows for cross-country comparisons.

OTHER ASPECTS



Recommended uses

This indicator is used to provide the value of custom duties levied by every importing country from all their trading partners.

Limitations

Tariffs are only part of the factors that can explain the degree of openness and transparency in the international trade arena. However, accurate estimates on non-tariff measures or of transparency indicator do not exist. Gender equality issues cannot be captured by this indicator.

Other comments

To further refine the quality of the information, additional sub-measurements could be calculated including: a) Tariff peaks (i.e. % of tariffs on some products that are considerably higher than usual, defined as above 15 per cent) and b) Tariff escalation (i.e. wherein a country applies a higher tariff rate to products at the later stages of production). These calculations were already provided by ITC as part of the MDG Gap Task Force Report. See the report for further information on the methodology at http://www.un.org/en/development/desa/policy/mdg_gap/mdg_gap2014/2014GAP_FULL_EN.pdf.
