the Canada Post tracking says something similar. for my package it said "International item arrived in Canada and will be reviewed by Customs". Then 6 minutes later "Item was released by Customs and is now with Canada Post for processing". It just sounds like a normal thing to me.
What would be the problem if it is just a bare diode, not a functional pointer?
I doubt they would hold all packages with laser diodes in them, especially the huge number of shipments that use dvd/bluray drives or projectors as the packaging material
Not to mention, even if they figured out the pinout for it, unless it was pressfit into a module WITH a lens already in place, it would just look like a strange LED right? Since it would be uncollimated?
I doubt they would power it up at all... who knows what something actually does when you apply power. If they do, i really want to see videos of them inspecting a shipment airbag inflators
