Tracking that stops updating and then resumes — the long version

Tracking that stops updating and then resumes — the long version — setting out what I have, and where I think it stops being reliable.

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

Parcel despatched 10 days ago, tracking last updated 5 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?

Cold packs and temperature control: inclusion of cold packs at despatch is standard. Whether they maintain temperature through transit depends on journey duration and ambient temperature. Long journeys through warm climates put product at risk.

Document outcomes rather than forecasting them. A forecast in this category reads as reassurance and is not one.

I have changed my mind on this once already, so take it as current rather than settled.

The arithmetic in post #3 is right; the assumption feeding it is the part to check.

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.

That has been true for the cases I have seen and I have not seen many.

Post #3 put the caveat in the right place and I want to underline it.

Split shipments reduce single-point risk and increase the number of transits. Which trade is right depends on what you are protecting against.

Take the reasoning and check the arithmetic; I do not always get it right.

Peak periods and public holidays affect this more than any other factor and are entirely predictable in advance.

Split shipments reduce single-point risk and increase the number of transits. Which trade is right depends on what you are protecting against.

Grateful for the specificity. Vague answers to this question are what sent me looking.

This follows post #7 rather than contradicting it.

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.

Anyone who has looked at this more carefully, please correct the record.

Post #10 is right about the mechanism and I think understates the practical bit.

Document outcomes rather than forecasting them. A forecast in this category reads as reassurance and is not one.

Coming back to post #10, because the follow-up matters more than the original answer.

Anyone deciding whether a delay is a problem should ask what would change if they waited another week. Usually the answer is nothing.

Tracking stops updating: tracking last updated days ago usually means the package is in transit and will not update until it reaches the next scanning point. No update for weeks means it might be stuck.

That distinction has done more work for me than anything else in this category.

Anyone deciding whether a delay is a problem should ask what would change if they waited another week. Usually the answer is nothing.

Caveat: everything above assumes the paperwork is what it says it is.
