Cold packs, phase-change material, and what survives ten days posts 31–60
This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

Good question, well framed, and I would like to see it answered properly.
Cold packs is well covered in the tag pages, and the older discussions are better than the recent ones because they were argued out properly. Worth twenty minutes before adding to this one.
The reason cold packs keeps being re-asked is that the answer is conditional and people quote it without the condition. It is not that the answer is unknown.
Where I part company with post #33, and it is a narrow parting.
Marking my uncertainty on cold packs explicitly. I am confident about the direction, much less confident about the size, and not confident at all that it generalises past the case in the first post.
If someone has run cold packs properly I would rather read that than my own reconstruction of it. Posting mine only because the thread has gone quiet.
Document outcomes rather than forecasting them. A forecast in this category reads as reassurance and is not one.
Two people in this thread mean different things by cold packs and are disagreeing about the definition while believing they are disagreeing about the facts. Worth pausing to define it.
Photographing the parcel on arrival before opening it takes ten seconds and is the difference between a report and a recollection.
The general case is well covered; this is the awkward specific one.
Something worth flagging about cold packs: the strongest-sounding claims in this thread are the ones with no source attached, which is the usual pattern and not a coincidence.
Worth separating two things that post #41 runs together.
Adding what did not work for me on cold packs, since the failures never get written up and they are half the useful information.
This follows post #41 rather than contradicting it.
Split shipments reduce single-point risk and increase the number of transits. Which trade is right depends on what you are protecting against.
Second-hand on cold packs, so weight it accordingly — someone whose method I trust told me this and I have not verified it myself.
Post #45 is right about the mechanism and I think understates the practical bit.
Delivery to an address where somebody is present is worth more for cold-chain material than any packing decision available to the supplier.
I have written this out at length because the short version keeps being misread.
Helpful, and easy to find again, which is half of what a good reply is.
Answering the question post #45 raises rather than the one it answers.
Two sentences on cold packs and then I will stop, because the rest is speculation and the thread is better without mine.
What is documented is narrow. What is inferred from it is broad. The gap between them is where every argument here lives.
Cold packs: I would want to see the raw numbers rather than the summary before agreeing. Summaries lose exactly the information that would settle this.
Declared contents and declared value are the two fields most likely to cause a query, and accuracy in both is the only strategy that survives.
I have left out the parts I could not verify.
I would keep cold packs and the decision it usually gets used for separate in this thread. They are related and they are not the same question, and merging them is why the last one went badly.
Post #53 is the version of this I will quote in future. One addition.
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.
Scoping that to what I have actually seen rather than what I have read.
Having read the whole cold packs thread before replying: the question in the first post has not actually been answered yet, and three of us have answered a nearby one instead.
Anyone deciding whether a delay is a problem should ask what would change if they waited another week. Usually the answer is nothing.
Following this. I have the same question and no better information than the first post.
I read post #58 twice before replying, because I had assumed the opposite.
The strongest argument against my own position on cold packs, stated as well as I can state it, since nobody else has yet.
