International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas: Held at customs…

Pushing back on DataDave here. Import rules are jurisdiction-specific and this board keeps giving US-shaped answers to non-US questions. What is a personal-import allowance in one country is a controlled-import offence in another.

The figures, for anyone assembling their own picture. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

Correct me if the detail matters more than I have assumed.

Adding the part of the answer the thread has not reached. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

One thing that is still open after CanadaChris’s answer:

Did your prescriber agree with that reading, and if not what was their objection?

OP back with an update, since a thread like this is useless without one.

Update, and it is the boring outcome: nothing was wrong. The measurement I was reading had moved less than its own week-to-week variation, which somebody said upthread and I did not believe.
