Defining a Query: Ad-Valorem Equivalent Tariffs

Ad-Valorem equivalent tariffs (AVEs) are retrieved as estimated by UNCTAD. This data type offers more limited country-period coverage than raw tariff data first because not all countries use non ad valorem tariffs and also because not all AVEs can be estimated.

In Select Data Type, choose:

• Tariff AdVal Equiv. Only to retrieve only tariff lines with estimated AVEs or;
• Tariff Total (Incl. AVEs) if you want to retrieve all tariff lines including AVE estimation when relevant.

Select the country for which you want to retrieve tariffs in Reporter. You will notice that Reporter offers a shorter list of countries (compared with the country list when Tariff - Raw Data is selected), those for which AVEs have been calculated.

Hopefully, these countries are the largest users of non ad-valorem tariffs.

Select a year in the Year list. Year availability depends on the selected reporter.

Select from the list of Duty Codes. You can select either one specific tariff structures (MFN for example) at a time or all of them by selecting All Duty Codes. However, retrieving all duty codes in one query is not recommended since the output will be a table that is very large and difficult to manage.

AVEs were estimated by UNCTAD using two different methods as described in Ad-Valorem Equivalents of non Ad-Valorem Tariffs. Choose one or all methods in Estimation method. However, retrieving AVEs based on both methods in one query is not recommended since the output will be a table that is very large and difficult to manage.

Finally, click on View Data to retrieve results.
