If the post at that site is correct, and I assume that it is, then there are all sorts of problems with MMS as it is now being sold.  (I'm not against the sale of MMS in any way, am just pointing out what is in the law.)

"To back up my views on concentration of NaClO2, i have contacted US Department of Transport (DOT), and it is the same world wide.
United States Department of Transportation (DOT) regulations require that sodium chlorite solutions containing greater than 5% NaClO2 carry a corrosive label.
DOT make exemption for some chemicals in small quantaties, but only to 1oz and chlorite sollutions are not included in this exemption.

This means MMS should carry a danger red diamond, have a caution lable containing “Keep out of reach of children”,UN 1908, CORROSIVE 8, HAZCHEM 2X and PG11, none of which are on there. They were appaled to realise bottles containing 55 oz were being express posted as well as bulk orders of 4 oz bottles, in dozens (48 oz) and even bulk of 100 4oz (400 oz).
MMS can not be posted or express posted as it is by distributors, to quote DOT they are breaking the law. This can be verified at the web site below

Whether the "problem" is political or not, makes no difference, the Post Office rules!  I bought many 35% h2o2 bottles on-line, but with the change in postal regulations, the shipping charge for a small bottle of it became obscene.  I now just go to my local health food store where it has been shipped via a non-postal ground carrier in large quantities, which make my in store purchase price much cheaper than on-line.

If the labeling is enforced per regulations, that alone will require additional costs.  I don't really see the elimination of MMS in small quantities, only the elimination of the current convenient access to it.

The poster on that site contacted the DOT to have them enforce government regulations.  Whether the poster's request will be acted on or if it will just stew in the government morass remains to be seen.
