Transit times by route, from a logged dataset

post #14 answers the question as asked. The question underneath it is different.

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.

At what point is a parcel genuinely a problem: if it was despatched weeks ago and there has been no update for days at customs, it might be held or lost. Days of delay at customs without update is ordinary; weeks without movement warrants inquiry.

Declaring contents accurately: declaring accurately reduces intervention risk. A declaration of "peptide research chemical, 5 grams" is better than "vitamin" or "other" because custom officials can verify a declared chemical is actually what was declared.

Coming back to post #16, because the follow-up matters more than the original answer.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.

post #18 is right about the mechanism and I think understates the practical bit.

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.

Worth separating two things that post #16 runs together.

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.

On post #17 — agreed on the reasoning, with one qualification.

Packaging integrity on arrival: if a parcel arrives with compromised packaging, that is evidence of a handling problem in transit. The contents may or may not be compromised but you have reason to be cautious.

Insurance and carrier liability: most parcel carriers limit liability. Understanding the limits before choosing a carrier matters if you are shipping expensive material.

Documentation after arrival: photograph the parcel and its contents on arrival. If something later turns out wrong (damage, loss, wrong item) you have evidence of the condition it arrived in.

Customs outcomes are not predictable at the level of an individual parcel. What is predictable is that consistent, accurate declarations correlate with fewer interventions, and that the same route behaves differently in different months.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.

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.

Reshipment after seizure: if a parcel is seized, some suppliers will reship; others will not. That is a supplier choice and should be understood before ordering in a jurisdiction with higher seizure risk.

This follows post #25 rather than contradicting it.

post #29 answers the question as asked. The question underneath it is different.

At what point is a parcel genuinely a problem: if it was despatched weeks ago and there has been no update for days at customs, it might be held or lost. Days of delay at customs without update is ordinary; weeks without movement warrants inquiry.
