The fridge compressors are often being sold to India etc etc.
They have high import tariffs on new steel and copper.
But no tariffs on fridge compressors as metal.
So there's people in India who import fridge compressors by the tons.
They get them, probably check to see if any are good, then they scrap them down to Ali, Copper, Steel.
The metals then sold on to refinery's and used to make stuff.



Basically its a way the government can make jobs for people, or gain from higher tariffs on 'new build - new steel projects.
