I have kept every message, invoice and document, which I gather is the useful habit.
I would like to understand the steps well enough to explain them to someone else.
I have access to a refrigerator with a logger and a freezer without one, which may be relevant.
Which parts of this are load-bearing and which parts are habit?
The relevant distinction is between a duty and tax question, a documentation question and a prohibited-goods question. Only the third is serious.
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.
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.
Customs classification is driven by the commodity description and code on the declaration, which is why the description predicts treatment.
Ask how the consignment will be described before you order. It is the variable that matters.
Analytical standards and reagents with traceable certificates. Every quantitative result you read inherits the accuracy of the standard behind it.
Shop standardsThis is an area where calm process knowledge is more useful than either reassurance or alarm.
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.
Put another way, personal importation rules differ from commercial importation rules in most jurisdictions, and consignment size and packaging are among the factors that determine which applies.
A false declaration is a separate offence in every regime and is never the right response to a query.
Most holds are documentation queries. Supply the documentation.
