How long customs clearance takes, and where the goods sit while it happens

Nobody publishes how long customs clearance takes, because it is a decision tree rather than a queue — and most of the branches are settled before the goods arrive. What does have a number is where the goods may legally sit while it happens: temporary storage allows up to 90 days, after which a customs warehouse authorisation is the usual answer. This sets out what decides the duration, the three types of approved facility, and which charges run while you wait.

How long does customs clearance take?

There is no published figure, and that is the honest answer rather than an evasion. HMRC does not publish a service level for clearing a declaration, because the duration is not one process with a queue — it is a decision tree, and most of the branches are decided before the goods arrive.

What can be said precisely is the shape. A complete declaration on goods that need no check is cleared by the system rather than by a person, which is a matter of minutes. A declaration that triggers a documentary or physical check waits for that check. And a consignment with a missing document waits for the document, however fast the border is working.

So the useful question is not how long clearance takes but what decides it, and where the goods are legally allowed to sit while the answer arrives. Both have definite answers, and the second one has a number: 90 days.

It is worth being blunt about why no figure exists. A published average would describe consignments nothing like yours — a correctly documented pallet of machine parts and a mixed load with a missing health certificate are not two samples of the same process. Any supplier quoting you a clearance time is quoting an expectation about your paperwork, not a property of the border.

What decides whether a declaration clears immediately?

Four things, in descending order of how often they are the problem.

1. Whether the declaration is complete and consistent with the commercial paperwork — the single commonest cause of delay is a mismatch rather than a rule.
2. Whether the goods need a licence or a certificate, which is a prior condition, not a customs question: see export licences and IPAFFS pre-notification.
3. Whether a check is raised, documentary or physical, which neither the importer nor the carrier controls.
4. Whether the duty can be paid at the moment of clearance, which is what a duty deferment account exists to take off the critical path.

Only the third is genuinely outside anyone's hands. The other three are decided weeks earlier, by whoever assembled the commercial invoice and chose the commodity code.

Where do the goods sit while they wait?

In temporary storage, which is a customs status rather than a type of building. Imported goods that have arrived but have not yet been declared are held in an approved facility under customs control, and the clock on that status is the number everybody needs and almost nobody knows.

HMRC's own application form for this approval states it plainly: temporary storage only allows up to 90 days storage, and for storage of 90 days or more you may want to consider a customs warehouse authorisation.

The status matters more than the address. Goods in temporary storage have not entered free circulation, no duty has been paid on them, and they cannot be sold, processed or moved on without a declaration — which is why "it is at the warehouse" and "it has cleared" are two unrelated facts that sound like one.

What is the difference between an ITSF, an ITSF-R and an ETSF?

Where the approved place sits relative to the port. Form TSA1 defines three, and the distinction is geographic rather than functional.

All three hold chargeable goods imported into the UK in temporary storage until they are released to free circulation, placed under a customs procedure or re-exported. The operational difference is that an ETSF moves the storage inland, which takes the pressure off the port and puts a road leg in front of the clearance — a point that matters to whoever is paying for the vehicle.

An approval is not casual. A facility must be suitable for storing, loading, examining and sampling goods, be secure and kept in good repair, and run a record-keeping system with an electronic inventory linked to HMRC's systems.

What happens when the 90 days run out?

The goods have to go somewhere with a different status, and the usual answer is a customs warehouse. Form TSA1 points at it directly: for storage of 90 days or more, consider a customs warehouse authorisation instead.

That is a change of regime rather than a lease extension. A customs warehouse is a special procedure with its own authorisation, under which duty and import VAT stay suspended for as long as the goods remain in it — our bonded warehouse article works through whether that is worth doing.

The planning consequence is that 90 days is a decision deadline, not a storage allowance. A consignment sitting in temporary storage because nobody has decided what to do with it is on a timer, and the decision gets made either by the importer or by the expiry.

How is temporary storage different from a customs warehouse?

One is a waiting room and the other is a procedure you apply for.

Unlike temporary storage, which every import passes through whether anyone notices or not, a customs warehouse is a deliberate commercial choice with paperwork attached. The two are sometimes the same shed, which is exactly why the distinction is worth stating.

Does the vehicle wait with the goods?

That depends on the model the port runs, and it is the question with the most money in it. At a port using the Goods Vehicle Movement Service the declarations are lodged before arrival, so a compliant movement is cleared on the move and the vehicle keeps going; our GVMS article covers how the movement reference is built.

Where goods go into temporary storage instead, the vehicle is discharged and the consignment waits without it. That is the better outcome for anyone paying for the vehicle, because waiting time is charged by the hour and storage is not charged by the hour — see demurrage, detention and waiting time for how those charges behave.

The failure case is the one in between: a vehicle held at a border point because the paperwork is incomplete and there is no approved place to put the load. Gov.uk sets out which movements need a reference, and that is the check worth doing before departure.

What makes clearance slow in practice?

Documents rather than decisions. Five causes account for most of it, and four are avoidable before the goods move.

The pattern across all five is that the border rarely invents a delay; it reveals one. A consignment that clears in minutes and one that sits for a week usually differ in the paperwork assembled before dispatch, not in anything that happened at the frontier.

What does the carrier need before the vehicle moves?

Four facts, and none of them is the commodity. A vehicle booked against a customs movement needs to know where it is going in customs terms, not just in postcode terms.

1. The approved place the load is going to — a port's own facility, an inland ETSF, or a customer address after clearance.
2. The reference the movement travels under, and who holds it.
3. Whether clearance happens before or after the road leg, because that decides whether the vehicle is waiting on a system or on a person.
4. Who is paying for waiting time if a check is raised, agreed before departure rather than argued afterwards.

Those four turn a customs question into a transport booking. Without them a driver is sent to a frontier with a load and no instruction about what happens next, which is the one scenario in this article that costs money in every direction at once.

What is our part in this?

We are a carrier, not a customs agent, so we do not lodge declarations and we do not hold a temporary storage approval. What we do is carry goods to and from these facilities, and the thing we need before a vehicle commits is the approved place the load is going to and the reference it travels under.

That matters because an ETSF is an ordinary road destination with an unusual legal status, and a driver sent to a port when the load is booked into an inland facility has made a wasted journey that nobody can fix at the gate. Our customs page sets out where we coordinate with a broker, and Heathrow cargo collections the airside-adjacent version of the same problem.
