Every slightly better source has more locations for sending packages. They probably send according to what they have and where in stock and according to the assessment of where there is a greater chance that the package will pass customs and/or reach you faster. The Netherlands is a European country with exceptionally well-regulated laws, unlike China, which is much more "relaxed" and I don't know why anyone would think that something suspicious is coming from the Netherlands, but if it comes from China, everything is ok. I get packages from the same source as in your case, sometimes from Europe and sometimes from Asia.

How long ago did you successfully order from Asia?
It could be that the source is having trouble getting packs through customs and theyre sending it to another country to be shipped to you from there, yes.
Since Trump started putting alot of pressure on China regarding fentanyl and counterfeit pharmaceuticals, the game has changed.

Im not saying that youre not getting ripped off. It wouldnt be suspicious to me if a source used a different country to ship from or reroute throigh etc. It happens often.

You said its been seized already though? More than once?

I started to order recently online from last year, always was PostNL and until now I never got seized, but one of the sources that I love to order here, they stopped to take my orders because probably somo shit is happening. So at this moment Im without order anything, lets pray and wait hahaha is what we can do it
