For reference: Germany · forty-two days.
Something has gone wrong and I would like to know how badly before I decide what to do.
Nothing else in the setup changed, which is what makes this puzzling.
What would you check first, and what would you conclude from each outcome?
42 days is about 30 working days once the weekends come out, and a customs queue runs on working days. The restatement matters: 42 days of silence feels like a decision, and 30 working days is usually a queue. Past 30 working days the distribution shifts. Routine clearance rarely runs this long, so the live candidates are a document query that never reached you, a valuation question, or a hold pending a decision you will be told about in writing. The tracking page is not the record. The record is the notice, and a notice arrives on paper or in a portal, not as a status change. Ask the carrier for the entry number and whether a query has been raised against it, in those words — "where is my parcel" gets the tracking page read back to you. And write the 42 days down somewhere durable now: if this becomes a dispute, the timeline is the thing you will be asked for and the thing nobody kept.
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.
To be exact about it, duty and import tax thresholds vary by country and by value, and are separate from any question of whether the goods are permitted. Paying a charge is not an admission of anything.
Customs classification is driven by the commodity description and code on the declaration, which is why the description predicts treatment.
Never answer a query with an inaccurate description.
Analytical standards and reagents with traceable certificates. Every quantitative result you read inherits the accuracy of the standard behind it.
Shop standardsMore usefully, the relevant distinction is between a duty and tax question, a documentation question and a prohibited-goods question. Only the third is serious.
The commodity description on the declaration is what drives classification. A vague description invites a query; an accurate one is processed on the classification it deserves.
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 has a deadline. Read it properly and take it seriously.

Answering this needs the destination, because customs regimes differ enormously and generic advice is close to useless.
Keep the documentation. Invoice, declaration, tracking history and any correspondence — if something needs resolving later, that record is what resolves it.
Suppliers differ in how they complete documentation and members have reported markedly different lane behaviour as a result. Asking how a consignment will be described is a reasonable pre-order question.
Personal and commercial importation are distinguished in most customs regimes by criteria including value, quantity and consignee.
The caveat is that nothing here is legal advice and jurisdictions differ more than any general statement can capture.
Ask how the consignment will be described before you order. It is the variable that matters.
The part that matters: a seizure notice is a legal document with a response window and should be read carefully rather than ignored.
Personal importation rules differ from commercial importation rules in most jurisdictions, and consignment size and packaging are among the factors that determine which applies.
Nothing here is medical advice, and research-use compounds are not approved for human use.
Keep every document. It is the only record that will exist.
The honest answer is that a hold usually means a form, and that occasionally it means something else.
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.
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.
