International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas:
Held at customs for 5 days, then released.
Tips: always include a copy of your prescription, declare medication properly on customs forms, keep quantities reasonable (personal use = 3 month supply max), and use a vendor who has experience shipping to your country.

I disagree that testing history is decisive. It tells you what a supplier did when they were being watched. Continuity of behaviour under stress — a late shipment, a failed test, a complaint — is more predictive than any run of good results.
Happy to go further on any of that.
