Second pass at: Transit times by route, from a logged dataset

On the subject in the title: Second pass at: Transit times by route, from a logged dataset Working notes rather than a conclusion.

A logistics question, since the answers here are usually better than anywhere else I have looked.

Parcel despatched 16 days ago, tracking last updated 9 days ago at a customs facility, no further movement. Cold pack included at despatch.

Two questions. First, at what point is this genuinely a problem rather than an ordinary delay? Second, if it does arrive, what is the actual decision process for assessing it, as opposed to the two extremes people usually offer?

Customs holds: if a parcel is held at customs and you can contact customs directly, declaring your personal use and providing documentation (order, labelling) can help. Most customs officials are reasonable when they know what they are dealing with.

Import restrictions by jurisdiction: what is legal to import for personal use varies enormously by country. Some jurisdictions are quite permissive; others are not. Checking your own country's rules before ordering is prudent.
