I am wondering... when B&H sends these powder C-41 development kits to Canada... do they affix any sort of warning labels to the outer package?

Although I understand that these kits are relatively low risk, and can be air mailed and possibly even taken in carry-on luggage, and the MSDS for the Unicolour kit (http://www.freestylephoto.biz/10123-...ng-Kit-1-Liter) seems fairly benign, I would not want anyone who might receive the package for me to be alarmed by alarming labels!

If you only have information relevant to other shippers, or to domestic shipping within the US, I would still appreciate if you could let me know what you have seen on your packages, if anything.

Thank you advance for your help!
