If it goes through customs they can open any package they want. In some cases they will sent to your local police. Local police can set up a controlled delivery. This can and has happened even on a small amount.
its the postal inspectors that will do that. if a personal amount is stopped at customs you'll usually always get a letter but if its stopped in this country by a postal inspector which is very rare that is when the problem arise
