so look, ISC stands for the International Service Center. so what they do there it is to collect mail from all of the airplanes and to sort it for customs to get inspected. plus, it is obviously is working in reverse of that as well as we are also having outbound customs here too and then ISC is sorting mail to the airplanes accordingly. either way, yes, it is true, your package is in customs, most likely. this is why you've seen many people saying that this is where your package can stay for however long. when people are saying this would be where you would see a problem, they are half way correct. we have seen that very well when there's a package that it is getting seized then the last tracking scan it is usually the ISC since it stays there to be inspected. however, as with everything else in the shipping you should know that there isn't any rules or anything, nothing is carved in stone so we just have to speculate.
also I must say that you still have not mentioned either your package it is EMS or it is registered (and no, you do not have to, it is at your own discreet), however if it is EMS then you would surely see the customs scans HOWEVER, it also may not show until it is going to clear the customs and then you are just going to see the in to and out of customs scans at the same time. after that the next scan is going to be at a post office which would be near SFO and it is also going to show a zip code too. as soon as you see this you should know that this means that your package has been accepted in to the domestic mail system and it is going to travel as domestic mail of that class. the EMS, as I have said in my previous post, is going to continue to scan and it is going to arrive to you in about 2 days or so from the date that it is going to clear the customs. that's because it is moving as express mail. however, if your package it is being registered then it obvious moves a bit slower so it can take up to like 2 weeks or so to get to you, but usually it comes within 10 days until it's at your door. but there is absolutely no rhyme and no reason to that too.. it all depends on how those people are moving there. I have had a package that cleared to Brooklyn and it has arrived to me in 5 days or so. the thing is that I can walk to Brooklyn in just a couple of hours. normally it should come to me the same day (a few minutes driving) or in the worst case the next morning (assuming it's not a working day). but for the EMS, there are sometimes when I can get it the exact same day that it is clearing the customs but this rarely happens, usually I am getting it, as I said, the next day morning. but anyway, this very much depends on how far away you are from customs as well as it depends on a lot of other things. that is why we cannot even guess. the time frame in which you can expect your package is just too big to speculate.
whatever the case, I am nearly fully sure that your package it is fine! no worries.
and yeah, by the way, in regards to that site, I just wanted to tell you that those other sites are just getting the information from the origin and destination sites. they are just querying the 2 sites and after that they are just showing everything that they are getting. and yeah, I do know that there are sometimes when it can show a little bit more than the other 2 sites, however this is mostly only because this information is being hidden on those sites… like for example, for some random and unknown by me reason, the USPS is hiding some information… however those other 3rd party sites like that one can somehow 'dig' that information (I'm clueless how, I guess they pay for it) and then they are showing it for you. that's nearly all.
whatever the case, I still think that you must remember what I have mentioned earlier in my post, you should not take the tracking too literal and you've got to try NOT to obsess over it. you're gonna end up being anxious… and the updates aren't always there… you know that there's someone who writes this online, so if that someone forgets to write it - no updates for you. plus to that, your package most likely is not going to update once again until it is going to clear customs and that can take as little as just a few hours to as much as a few weeks so there's no reason for you to stay and sweat out waiting for the update. I tell you that using an IOP it is surely not for the faint at heart, however you are going to get used to it if you are going to go again this route and more often. in the end of it you are going to see that it is really not as bad as it might seem it to be. it just depends very much on what is your attitude towards this.
and oh yeah… one last thing here that I forgot to mention but I think it is very important to be told to a newbie like you who is getting anxious… you need to remember and to keep in mind (it would help you calm down) that there are literally tons of packages that are entering the US from all around the world and they just can't look in all of them. and just remember that those packages are containing all sorts of things in them… and plus to that, customs also is seizing all sorts and types of things, not only medicine alone. there's a lot which shouldn't enter the customs and they get it. you've got to keep the entire process in perspective. I remember that once I have found posted the amount of packages that are being transited through JFK POE in just a year period of time… unfortunately I forgot where that post is now and I can't give you an certain answer and that's why I am not going to try to guess here, what I do remember is that it is pretty damn incredible the amount it goes yearly… I must find the exact number because it is going to give a completely different perspective of the entire process.. It is going to change your views on this thing and on the shipping and tracking discussion as whole. I know this because I have felt it myself. so taking all of this in consideration I am sure that your package is gonna appear. I'm pretty sure that in a few more days you're gonna come with an update saying that your package cleared customs.
so thanks, thanks a lot. that's a really good information, useful for me and my anxiety as I am now done obsessing and bitching about it. you've really helped me, my body, my brain and my central nervous system
