Overseas package, WTF is that smell?

Recently, I've ordered several things that were manufactured overseas and I'm overwhelmed by this pungent oil/plastic/mothball/old piss smell. Mostly on car parts or tools, but my new Moya gi reeked of it, even after I washed it! Are these products being manufactured in a sewer? Is my nose getting old and complainy like the rest of me?

my wife orders stuff for her nail salon business from SE Asia and it always arrives smelling weird as fuck. although it is kinda neat to get to go through the thai and viet newspapers that they use to pack in the boxes.
