I can understand the paranoia if you're new to this sort of thing. Customs seizures aren't as big of a deal as you probably think they are. If you have a package seized, they'll just send you a letter letting you know that they're holding something with your address on it and that you can get ahold of them if you think they've made a mistake. In Canada I had 2 packages of pills seized within 3 weeks of each other and all they did was send me a letter for each of them. If they find weapons, narcotics, or 5kg of raws it might be a different story, but the reality is they're seizing stuff constantly and they just don't have the man-power to kick in someone's door everytime they find a bottle of test from China. I wouldn't worry. Just pull the trigger and enjoy the thrill of breaking the law
