I have kept every message, invoice and document, which I gather is the useful habit.
I want to understand what this actually establishes, as opposed to what it is being used to imply.
My concern is that I am being invited to draw a conclusion the data does not support.
What does this actually establish, and what does it not?
Answer first: how the consignment is described on the declaration determines how it is treated, and that is a supplier decision you can ask about before ordering.
Most holds are documentation queries: an incomplete description, a missing value, an unclear commodity code. They generate a request for information and resolve when it is supplied.
| Packing | Ambient | Time below 10 °C | What that means on a 12-day lane |
|---|---|---|---|
| One phase-change pack, thin-walled box | 25 °C | 1–2 days | At ambient for roughly ten of the twelve |
| One phase-change pack, thin-walled box | 35 °C | under 1 day | At ambient for essentially the whole lane |
| Two packs, insulated liner | 25 °C | 2–3 days | Buys a day; does not change the conclusion |
| Lyophilised solid, no pack | 25 °C | not applicable | Dry powder is chemically stable at ambient |
| Anything in solution | 25 °C | not applicable | A different risk entirely; hydrolysis proceeds |
A liquefied pack on arrival is the expected outcome rather than evidence of a problem. A single-use logger, not a heavier pack, is what turns this from speculation into a record.
Personal importation rules differ from commercial importation rules in most jurisdictions, and consignment size and packaging are among the factors that determine which applies.
Seizure procedures include a stated basis and a defined response period in most regimes, which is why the notice itself is the important document.

Do not respond to a query with a false description. An inaccurate declaration is a distinct and more serious matter than whatever prompted the query.
A seizure notice, where one is issued, is a formal document with a stated basis and a response deadline. It is worth reading carefully and, if the amount matters, worth advice.
The caveat is that nothing here is legal advice and jurisdictions differ more than any general statement can capture.
Never answer a query with an inaccurate description.
