The case in front of me: the Netherlands · twenty-eight days.
I think I have a problem. I am not yet sure whether it is a real problem or a measurement artefact.
I want to know whether this is recoverable or whether the honest answer is to write it off.
How do I distinguish the benign explanation from the one that matters?
28 days is about 20 working days once the weekends come out, and a customs queue runs on working days. The restatement matters: 28 days of silence feels like a decision, and 20 working days is usually a queue. Past 20 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 28 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.
The honest answer is that a hold usually means a form, and that occasionally it means something else.
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.
| Lane | Reported range | Median | Where the variance comes from |
|---|---|---|---|
| Coastal China → western Europe | 8–14 days | 11 days | Customs queue at the destination hub |
| Inland China → western Europe | 10–16 days | 13 days | Domestic leg to the international gateway |
| China → United Kingdom | 8–13 days | 10 days | Single clearance point, usually quick |
| China → United States, west | 8–16 days | 12 days | Onward domestic carrier |
| China → Australia | 10–20 days | 15 days | Fewer direct services; inspection rate |
| Regional warehouse → same region | 2–5 days | 3 days | No clearance step at all |
These are ranges members have reported, not quotes. Judge a lane on whether tracking scans continuously rather than on days elapsed.
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.
Import duty and tax thresholds are published per jurisdiction and are independent of whether goods are permitted.

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.
Keep the documentation. Invoice, declaration, tracking history and any correspondence — if something needs resolving later, that record is what resolves it.
Prior successful deliveries establish nothing about the legality of the next one.
Keep every document. It is the only record that will exist.
Start with the fact that a customs hold is an administrative event with a defined process, not an enforcement action by default.
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.
Personal importation rules differ from commercial importation rules in most jurisdictions, and consignment size and packaging are among the factors that determine which applies.
Customs classification is driven by the commodity description and code on the declaration, which is why the description predicts treatment.
Most holds are documentation queries. Supply the documentation.
It helps to be literal here: a seizure notice is a legal document with a response window and should be read carefully rather than ignored.
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 false declaration is a separate offence in every regime and is never the right response to a query.
Never answer a query with an inaccurate description.
Answering this needs the destination, because customs regimes differ enormously and generic advice is close to useless.
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.
Personal and commercial importation are distinguished in most customs regimes by criteria including value, quantity and consignee.
Ask how the consignment will be described before you order. It is the variable that matters.
