lowest tariffs:
177 Switzerland
177 Singapore
177 Hong Kong (China)
177 Macao (China)
177 Libya
Oddball case. Any poor countries near this end of the list are in some odd category. By some other factors they would probably be much farther down the list.
176 Norway
175 Brunei
173 Georgia
173 Albania
172 Mauritius
171 Israel
170 Iceland
169 Croatia
142 United Kingdom
142 Finland
142 Cyprus
142 -- Most of the EU countries are ranked at 142 here.
etc.
some select countries down the list:
134 United States
If President Trump somehow imposes his high punitive tariffs, then the U.S. would move farther down the list, toward Mexico and China. You can see the odd cases of Argentina and Brazil below, which are listed as very high-tariff countries. For a more developed country, S. Korea is noteworthy in this ranking, as a high-tariff country. It and China are both criticized for their protectionist practices. But considering that China is actually still poor by comparison, per capita, it fits the overall pattern here, lower in the rankings.
102 Korea
083 China
081 Mexico
Of the Latin American countries, most of them are below Mexico on this list.
030 Argentina
017 Brazil
etc.

012 The Gambia

010 Central African Republic
009 Ethiopia
008 Gabon
007 Cameroon
006 Congo
005 Equatorial Guinea
004 Djibouti
003 Iran
002 Tunisia -- somewhat odd case.
001 The Bahamas -- extreme exception to the rule
The important point is the general pattern of richer countries higher up, in the low-tariff category, with the poor countries mostly toward the bottom. This pattern goes back many generations, showing that poor countries have tried to protect their "jobs" from foreign imports, and this shows no indication of having improved their living standard.
