Effectively Applied Tariff

[K A-G]

I wanted to find out how the effectively applied tariff rates (AHS) are calculated when you select World as the trading partner for a reporting country. According to the handbook, WITS uses the lowest available tariff granted by a reporter to a partner for the considered product as the effectively applied tariff. However, when the partner is "World," and not an individual country, how is the effectively applied tariff calculated? Is it just the simple average of all the effectively applied tariffs for every partner country, the lowest available tariff among all the tariffs for any partner country, the weighted average of all the effectively applied tariffs for all partner countries, or is it calculated by some other method? 

Also, I have a few other questions. Why are the effectively applied tariff rates higher than the MFN rates for some countries and years, and why are the weighted average tariff rates higher than the simple averages for some countries and years? Also, whey are the effectively applied tariffs greater than the bound tariff rates for some countries and years? Lastly, why do the number of tariff lines differ for the different tariff types (e.g. MFN, BND, and AHS rates)?

Thank you.

Dear  Sir,

For AHS, when World is selected as  partner,  the simple average tariff is calculated by aggregating, over all trading partners, the lowest applicable tariff  for each partner.

In WITS, when you select  an individual country as a partner, the average tariff for both MFN and AHS  is calculated only for those items where there is trade.  When your select
'World' as a partner, the MFN is calculated using all items regardless whether there is trade or not whereas AHS is calculated using only traded items. This is why sometimes, in rare cases, AHS may be higher than MFN.

I hope this helps, otherwise feel free to get back to us.
Best Regards,
Sam

Where can I find the proper definition of AHS tariff? I am looking at commodity HS8703, reporter US, partner Japan. I don't understand why 2012 shows a 1.5 tariff rate when this is supposed to be 2.5.

Please advise.

Thanks,

[Samuel Munyaneza]

I guess you mean 1.25  as the average tariff for HS8703-US imports from Japan.
Not sure why you think the correct average tariff  should be 2.5.  There are 8 subheadings under the heading HS8703 (870310,870321,870322,870323,870324,870332,870333 and 870390) all with an average tariff of 1.25.  This is why 1.25 is correct.

Remember: In WITS even the simple average is calculated based on traded goods.

Hie. Hope this finds you well.

I am gathering data on MFN, AHS and Bound Tariffs, In many cases there are zero values for MFN and AHS. Does that imply the value is zero or it implies there is no data? If its the former, can i then use Bound Tariff?

Thank you

Can you provide an example for us to investigate why the tariff is missing. One possibility is that you didn't specify to use AVEs in your query.
