Here's an example:
"This Free Trade Agreement eliminates duties on 90% of tariff lines."
Sounds impressive? Maybe.
But what if I told you that in 2018, 81.52% of UK exports to the EU occurred in just 9.99% of lines?

Original data downloaded from the wonderful folks at @ITCnews.
X axis is the number of tariff lines (at 6 digit level).
Y axis is the total percentage of UK's exports to EU that fall within them.
As you can see virtually all the action is happening in the first 1000 lines (out of 5413).
