Fedex
Customer has requested non-express clearance

Hello there,
I bought a GoPro 4 on the official website to have it sent to Mexico I did choose the "FedEx International Priority".
Last saturday, 18 of October, the GoPro landed in Guadalajara, Mexico, showing some "Clearance Delay", ok, fair enough, it does have to go trough customs, no problem.
I was keeping an eye on the tracking and this morning, Tuesday the 21 the FedEx page show a new "Customer has requested a non-express clearance"
What the does that means, any clue?
I was kinda naive, thinking that the "International Priority" was like, you know, "yeah, I want my stuff quick, express way"
I imagine this clearance delay have something to do with customs but why the non-express comment is showing now?
