I am comparing three suppliers on documentation rather than on price.
I have read the primary source rather than the summary, which has left me with more questions.
I understand the headline. I do not understand the footnotes, and the footnotes look important.
What would I need in addition before this supported a decision?
Start with the fact that a customs hold is an administrative event with a defined process, not an enforcement action by default.
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.
| 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.
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.
Import duty and tax thresholds are published per jurisdiction and are independent of whether goods are permitted.
Never answer a query with an inaccurate description.

Visit GL BiochemThe honest answer is that a hold usually means a form, and that occasionally it means something else.
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.
Keep the documentation. Invoice, declaration, tracking history and any correspondence — if something needs resolving later, that record is what resolves it.
Personal and commercial importation are distinguished in most customs regimes by criteria including value, quantity and consignee.
Prior successful deliveries establish nothing about the legality of the next one.
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.
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.
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.
The caveat is that nothing here is legal advice and jurisdictions differ more than any general statement can capture.
Keep every document. It is the only record that will exist.
Worth being precise here: this is an area where calm process knowledge is more useful than either reassurance or alarm.
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.
Ask how the consignment will be described before you order. It is the variable that matters.
The short version: most holds are documentation queries, most resolve, and the paperwork description is the variable that predicts them.
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.
Most holds are documentation queries. Supply the documentation.
