VGM[1] has been put in place in 2016 to improve safety. Liners reported high compliance shortly after adoption [2] and [3]. This reporting of self-compliance should of course be taken with a grain of salt.

I'm not saying it's not a problem but am merely pointing out that progress is being made with regards to weighing containers.
