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.
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.
To be exact about it, personal importation rules differ from commercial importation rules in most jurisdictions, and consignment size and packaging are among the factors that determine which applies.
The caveat is that nothing here is legal advice and jurisdictions differ more than any general statement can capture.
Never answer a query with an inaccurate description.
