Question Chemical Sellers Mislabeling?

[CryoThio]

So I was wondering if anyone knows if sellers of chemicals in China or elsewhere will mislabeled cannisters of chemicals. Does that even work?

Like could they have a label of "ammonia" on a cannister, but it actually be methylamine?

Lot of vendors from China misabel chemicals because without it it would be 99% catched. But there are spectroscops at airports etc and it is checked. Since I have big experience with import/export and have few companies in few countries I know that they check it very well - misabelled and found that is misabelled chem -> raid of receiver or controlled delivery it depends.
