Plane Arriving and Arrive at Destination on ACBuy’s UK postal lines
Two statuses that can sit unchanged for days. ACBuy explains both in short articles written for postal routes; this page reads them line by line and adds what gov.uk says about the UK end.
Illustrative status sequence: the example days are not a delivery forecast or a claim deadline.
- day 0Departure from export airport
- day 1Plane Arriving
- days 2–5no new scan
- day 6Arrive at Destination
- days 7–12no new scan
- day 13Customs release
Other stalled statuses: tracking not updated and repeated UPS Warehouse Scan.
Which of the six UK lines are postal routes
Both ACBuy articles open with “when you use postal routes”. Three UK lines describe themselves that way in the estimator: EUB-HN, EMS-HN and EMS-HZ (60) each begin their line note with “Economic route, cooperation with China Post, postal clearance” and end with “The local post will provide destination delivery service.”
The two Royal Mail lines are described differently: a tax-free air route with Royal Mail handling the last mile. ACBuy does not say whether its postal-status articles cover them, so on those lines read this page as background and ask the carrier or ACBuy which explanation applies to your actual line. UPS(HK)-5000 is an express line with commercial clearance and has its own article.
The difference shows up on the tracking page itself. A postal-clearance parcel passes through customs as post, so the entries come from the postal chain: export, flight, arrival, a long customs pause, then the UK post. A commercial or tax-free air line tends to show handovers between logistics companies instead. If your page reads like the first pattern, this page is the right one to read.

Plane Arriving covers three different places
ACBuy’s article on Plane Arriving makes one point first: a parcel stuck on this status has not necessarily reached its destination, and it is not necessarily stuck. It is the air-freight stage, and it hides three situations that the tracking page does not tell apart.
- Awaiting flight. Cleared export customs, delivered to the airport warehouse, queued for a specific flight. Weather, schedules, cargo space and airport efficiency set the wait.
- In transit or transferring. In the air, or landed at a transit airport waiting for the next flight. Updates may be sparse here.
- Arrived, awaiting processing. Landed and unloaded, but not yet received, scanned and sorted by the airport warehouse, so the next step has not been recorded.

What ACBuy asks of you while it says Plane Arriving
Patience, mostly. The article calls the status a normal and essential part of international shipping and says it may last several days without any change in tracking, which is usually normal. Busy airports with heavy flight and cargo volumes take longest at the third stage.
If you want someone to look, ACBuy’s online customer service is the route, and the article asks you to quote the parcel number in the form APXXXXXXXX or the logistics tracking number. That is the whole of ACBuy’s advice for this status: no day limit is set in the article itself.
The separate Tracking Not Updated article discusses re-labelled parcels and a seven-day contact point with flight/customs exceptions. It does not establish a universal deadline for Plane Arriving. If the promised delivery window passes or you receive a request, contact the carrier or ACBuy with the parcel reference.

Arrive at Destination: landed in the UK, not yet cleared
ACBuy calls this a key milestone: the flight has landed in the destination country and the parcel is ready to enter customs clearance. The international part of the journey is largely complete.
It is also where tracking can go silent for longest. ACBuy says information may stagnate for several days or even longer after this status and that this is usually normal. Nothing else will appear until the parcel enters the next stage, typically customs release or handover to local delivery.
The article is titled “Arrived at Destination – No Further Updates”; the title does not provide a frequency or a guaranteed wait time.

Three reasons the page sits still after landing
ACBuy lists three, and all of them sit outside ACBuy’s reach:
- Customs backlog. UK customs takes time to make random checks, assess tax and complete other procedures on imported parcels.
- Handover delay. The airline unloads at the airport and passes the parcel to the local logistics provider or customs; airport congestion stretches this.
- Slow data. The parcel may be moving while the scanning and upload systems lag behind.
None of these explanations alone establishes whether your specific parcel has been lost. They are reasons for a wait whose length nobody in China can predict, which is why ACBuy points you at the UK side for news.

The four steps ACBuy lists once the parcel is in the UK
- Wait. Customs timing varies by country, and the page usually updates only when the parcel moves to the next stage.
- Ask the destination customs. ACBuy suggests that, as the recipient, contacting local customs is the most direct way to learn the real situation, with your tracking number ready.
- Provide documents if asked. If customs needs documents, ACBuy says you can download the relevant customs invoice from your package details page and submit it as required. Keep it accurate to what is in the box.
- Contact online support. If customs says no such package can be found, ACBuy reads that as the parcel still waiting at the airport warehouse. For a long stall or anything complicated, send support the AP parcel number.

The UK end, in gov.uk’s words
The gov.uk guide to goods posted from abroad, read on 16 October 2026, puts customs clearance on the carrier: Royal Mail, Parcelforce or a courier takes the parcel through UK customs and tells you whether VAT or duty is owed. Its advice for a late parcel is just as short: get in touch with whoever is delivering it.
That lines up with ACBuy’s advice to look to the UK side once a parcel has landed. It also explains why ACBuy support often has nothing new to add during an Arrive at Destination stall: the information sits with the carrier in Britain. Read the gov.uk guide.
If a bill arrives, the same guide allows the carrier roughly three weeks of holding before a return; the UPS page covers that case.
