I have however, spotted some odd data in the category:
 
List of importing markets from Organisation for Economic Co-operation
and Development (OECD) for a product exported by Malaysia
Product : 721720 Wire of iron or non-alloy steel, zinc plated/coated".

That shows unit values varying from USD$4.40 and US$59 per tonne,
whereas the world and other is US$241 to US$1,123 per tonne.
 
I think there are some errors in the Australian data in particular.
Would you look into that please
