I don't think you are going run into any problems in most countries if you
can at all explain what you do with it.
But then, i have heard of people having "visits" after buying some simple
chemicals that are often used in illegal drug labs, in the US i think. Not
that anyone got into trouble - they just asked what is beeing done with it.

Me personally, i was never asked in the chemicals shop what i am gonna do
with the stuff, even if it was something on that "list" where they should
ask (stuff which you can't easily mail-order without paperwork). Neither
was i ever asked for identification of any sort, so "the authorities"
wouldn't have any way of knowing who i am.

Procedures are different all around the world, and attempts at preventing
terrorism are often unreasonable. For example if you want to send a letter
to Israel from here you are supposed to bring it to the post office
unsealed, for inspection before it is sent. You can imagine it was not
uncomplicated to send PCBs to Israel for me, which i do from time to time,
since the appearance of the PCB prompts a worried "and nothing is going to
happen with that, right?" from the clerk, repeatedly. The trick is there
is only one clerk that insists on this inspection (how do you say - "full
of piss and vinegar" isn't it?), and if you have a careful look and queue
in the right line to get one of the ladies that couldn't care less what
you send to israel you will have no inspection. (That there seem to be
queues at this post office always and at any time of day is another
peculiarity of that particular one, but then, with one letter double the
weight beeing more expensive than two letters half the weight together i
should not be surprised any more about peculiarities of our postal system.
I could list many more...)
