I recently received a package from Washington state. It was shipped
book rate media mail rate through United States Postal Service (USPS). On the front was a notice “Opened by USPS for inspection” or something along those lines. It was a gift for a friend. When I opened the box, there was a letter from USPS where it indicated the reason for the opening: https://about.usps.com/notices/not121/not121.htm.

It met the qualifications, but they waited until it was here to check for it. Personally, I would have preferred they checked it before it left the town in Washington state it was mailed from.
I can’t speak for other countries who have similar restrictions, but be aware and follow whatever restrictions your country’s postal system has in place. It was strange because I have received hundreds of book rate/media mail rate packages over the decades, and this was the first one flagged. I am pretty sure at least some of those items didn’t meet the requirements listed above.
