Personal import allowances, compared — a second dataset

Import rules for personal quantities are jurisdiction-specific and change without much publicity. Establishing your own position is unavoidable.

One more thing on Personal import allowances that took me far too long to see: the two figures people quote are not measuring the same quantity. Once you notice that, the apparent contradiction disappears.

Agreed on Personal import allowances, with one qualification that I think matters. The reasoning holds for the case as described. Change the starting assumption and it does not, and the starting assumption is the part nobody states.

Narrowing post #56, because the general version has more than one answer.

My understanding of Personal import allowances is a few years old and may have been superseded. If it has been, I would genuinely like to know rather than keep repeating it.

Where I would push back on the Personal import allowances consensus is the confidence, not the direction. The direction looks right. The confidence is borrowed.

Customs and import outcomes: different routes have different seizure rates. Some countries are stricter on peptide imports than others. History on a route is more predictive than theory.

The uncertainty is in the assumption, not in the calculation.

The failure mode on Personal import allowances is boring rather than dramatic. It is almost always the step everyone assumes was done correctly because it is too simple to get wrong.

Post #104 describes the usual case. This is about the unusual one.

I disagree with the framing of Personal import allowances above, and I think it is a substantive disagreement rather than a terminological one. Setting out why, so it can be checked.

The reasoning depends on an assumption that is doing a lot of work and is never stated. If the assumption holds, the conclusion follows. I do not think it holds generally.

Building on post #127 rather than restating it.

On Personal import allowances, I would rather understate and be corrected upward than overstate and be quoted. That is a house style here and it is a good one.
