States which appeared in the NA data and had 2000 or fewer GTAs in the RB data - i.e. states that we may want to target scraping for.

## [1] "ES" "PB" "PI" "PR" "RJ" "RN" "SE"

Also a visual assessment shows that in MG & PE we had a lot of GTAs from NA in earlier years, though this has now dropped off - these would be worth targeted scraping.

Below I list these states in order of what proportion of exports they made up in 2015-2017. Only four states exported.
