Yes more gear is getting seized these days and no they don't examine every package coming into a country. They pick out the suspicious packages like stuff coming from certain countries. They know exactly what their looking for they have stopped so many packages and alot of suppliers don't bother changing their packaging.
It's not hard to get gear passed customs but most of the packaging is crap and unfortunately some suppliers could give two shits. How many times does gear in a bubble envelope make it through customs ? hardly ever ! Do some suppliers still ship this way ? yes because they don't care, money is already in their pockets.
Over here you'll be lucky to get a seizure letter anymore from Canada customs. The reason is because they know most companies will reship with prof of seizure. They take your stuff don't send a letter and they don't have to stop another package from coming in.
Screw customs and their gear stealing asses domestic is the shit !!!!!!!
