I think what most likely happens is:

Computer automatically scans shapes for prohibited items. Your blacklisted address comes up and the agent carefully looks at the screen and declaration as it passes through. If he/she isnt satisfied, then the package is opened. If there is no prohibited item, then the package is let go. An automated system can store a whole lot of addresses and can automatically sort through. Not to mention, all the blacklisters dont order stuff everyday so the system isnt overloaded.

LOL your name is Koopa.. Means Poo

At the end of the day.. its a hobby, a sport, not life and death..
Its not worth making your life difficult over.. If you think it may get seized.. Don't buy it.
If you think it would put you on the blacklist.. don't buy it.. unless you look forward to rectal exams by CSBA agents..

fixed...

mmm I dunno but I would guess they randomly open containers, check all the container's load, and switch to another randomly selected container.
They probably select primarily loads from Asia, because from Europe it's very easy to get your parcel unchecked.
I don't think there is such a thing as a blacklist, but there's probably a file for each package that was stopped, with the recipient's name.

LApolicegear, and oneshottactical were fine for me
But anything my friends and I ever ordered from blackhawk was ALWAYS inspected by customs

And you do absolutely get flagged for bringing in restricted items. If it's not restricted your fine. If your caught bringing in something clearly illegal, they most definitely check every package coming your way for a certain period of time.
Buddy of mine had a desktop picture of himself playing airsoft on his laptop, they saw it at the airport and he got flagged for 5 years. Clear overreaction to nothing, but all his packages went through customs, all the time.
And I knew one of our old importers really well, and his CBSA profile had more flags than the united nations....

Ever think the possibility of a blacklist is actually more effective than the real list?

There is 100% certainly a black list.

This is information coming directly from one of my good friends who is a CBSA officer.

Well there you go, straight from the horse's mouth lol

You can tell certain HK retailer are blacklisted already
RSOV is a really good example
Redwolf Airsoft is another one
Ehobbyasia to some extent.

I've never imported illegal parts but I did import alot of stuff that misinformed CBSA would think it's illegal (Airsoft suppressor, GBB parts like Complete Lower Receiver parts kit and bolt carriers) I got my stuff open quite frequently, to the point even hose, tank regulator are even opened. The only times it didnt letter mails.

Sounds pretty tough for us lol. The CBSA sounds kinda like communists (no offense to anyone if they are left winged; im just reading my textbook cuz i have an exam tomorrow and communists came up in the reading :P ) cheers~

Good example of who's on the list is east coast airsoft. I wish evike was on the list too though. :p

If you're in the system for a previous seizure, that shows up at every point of entry, period. You then get pulled aside for some extra questions. The system for the land border is the same as for the airport. I had a few people that got flagged for stuff they did down in Sarnia. As for the mail, I assume that there is a similar system in place. If it's bad enough, they'll take notes...if you break the "take a note of this guy" threshold...unfortunately, I can't tell you exactly what would put you there (because I worked with passengers, not postal). Good luck!

I know this is pretty random but if you have time, read up on David Harvey. He's a pretty interesting guy IMO. (Yeah, I'm studying about him right now).

Godwins law prevails.... The CBSA is more like the Nazi's than anything. (I don't know if they are, I just wanted to get Godwins law out there)

Just one question though, why is RSOV on there? isn't the main bulk of their sales from accessories and not actual guns or lowers and stuff? I'm sure people have probably ordered that shit before but AFAIK their main sales are for mostly unrestricted stuff.

Also, does anyone know if places like Airsoftpark and similar sites (ie. DragonRed) are blacklisted? I know they have airsoft in their names so might bring up some flags but for the most part they sell unrestricted stuff.

Keep in mind the CBSA isn't only there to restrict airsoft stuff... that's a VERY SMALL part of their job lol
