Yep, I don't think sending individual items will raise any alarm -unless there is a "terror alert" and people get paranoid". If I'm a factory and want to ship boxes of my stuff abroad, it just makes sense to find and alternative way. Aerosols and flammable liquids are forbidden, but I travel with my shaving foam spray and my "eau de cologne" and until now, I have never been fined for that.
I guess the best bet is to erase any sign about the "hazardousness", be creative on the description, and send it along. The problem is that security personal are instructed not to use the little common sense they could have, so they just follow directions and can't decide whether something is hazardous or not just by following their common sense. I recall somebody at the check-in told me that if I carry an alarm clock in the suitcase I had to switch it of, because if it rings it could raise an alarm -no pun intended- "what?" If there is a bomb inside a suitcase, I doubt the bomber will make the clock will ring before the big bang.
This could be an endless debate. I have stated before what big incongruency it is that the police in Spain can arrest you for carrying a knife, but nothing will happen to you if you carry an x-acto knife.
