Cold-chain shipping — 6 month update

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 LabKate, 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.

Adding the numbers, since they settle part of this. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.

There is a second half to this that has not been said yet. The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either. Those three things can all be true at once, and most arguments here are two people holding different parts of that.

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?

Closing the loop on my own question.

Following up because I said I would. I changed one thing, left everything else alone, and waited the full interval before looking. It resolved, and I cannot prove which half of that did it.
