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

I read this differently from COA_Karl, on substance rather than tone. 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.

One concrete data point for the thread. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.

If somebody has the primary source to hand I would rather cite it than paraphrase it.

There is a second half to this that has not been said yet. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

A narrower follow-up, since the general answer is now clear:

What did you change at the same time, and can you separate the two now?

Reporting back.

Closing the loop. The answer turned out to depend on the detail I had left out of the opening post, which is a lesson about how to ask rather than about the subject.
