Moving overseas involves a lot of moving parts, but customs is often the one that catches people off guard. Everything can be packed and shipped smoothly, only for the shipment to sit at the port for days or weeks while paperwork issues get sorted out. That delay usually comes with storage fees or no clear timeline for when it will end.
Most customs delays come down to a small number of avoidable mistakes rather than bad luck. Complete paperwork, an accurate inventory, and a clear understanding of your destination country’s rules are usually all it takes to avoid them.
Below are the most common causes of customs delays and how to prevent them.
Why Shipments Get Stuck at Customs
Every shipment leaving the US becomes an import once it lands somewhere else, even if it’s just your own furniture and kitchenware. That means it falls under the same customs system used for commercial cargo.
The most common reasons a shipment gets held include:
- Missing or incomplete documentation, such as a passport copy, visa, or proof of residence.
- An inventory that doesn’t match what’s actually in the boxes.
- Restricted or banned items packed without anyone realizing.
- No customs relief application submitted, or one submitted too late.
- Incorrect values or descriptions on the customs declaration.
- Vehicles or high-value items with unclear ownership history.
Any one of these can trigger a physical inspection, and inspections mean your container sits at the port while an officer works through it. That’s lost time and, often, storage charges you didn’t budget for.
Start the Paperwork Early
Most customs relief schemes need to be approved before your goods travel, not after they land. If you’re shipping into the UK, for example, Transfer of Residence (ToR1) relief removes the customs duty and 20% import VAT you’d otherwise pay on your belongings, but the application has to be submitted and approved in advance.
HMRC’s own guidance points to processing times that can stretch well beyond a few weeks, especially during busy summer months.
A few things worth knowing about ToR relief:
- You’ll usually need to have lived outside the country for a set period, often 12 months, before you qualify.
- Items you’re bringing in must have been owned and used for a minimum period beforehand, commonly six months.
- Vehicles have their own ownership rules and are checked more closely than household goods.
- The reference number you receive is only valid for a fixed window, so timing your move around it matters.
Every country runs its own version of this, with different forms, evidence requirements, and waiting times. Applying six to eight weeks before your move gives you breathing room if HMRC or the equivalent authority abroad asks for more information.
Build an Inventory That Matches Your Shipment
Customs officers check your paperwork against what’s physically inside the container. If your inventory says “assorted boxes” and an inspector opens one to find a full drum kit, that’s a red flag, even when nothing illegal is involved.
A clearance-ready inventory should:
- Group similar items together with reasonable detail, such as “40 items of clothing” or “1 washing machine,” rather than vague catch-all terms.
- List anything of high value separately, including electronics, jewellery, and instruments.
- Flag vehicles, pets, and firearms on their own, since these usually need separate paperwork entirely.
- Stay consistent with the values and descriptions used on your customs declaration.
Getting this right at packing time is what keeps the declaration and the physical shipment lined up when it reaches the other end.
Know What You Can’t Ship
Every destination has its own restricted and prohibited items list, and it rarely matches what you’d expect. Plants, certain foods, some medications, and even old furniture treated with particular chemicals can all cause problems in specific countries.
Australia and New Zealand, for instance, are especially strict on anything organic, including wooden items and outdoor equipment with soil residue.
Before you pack anything borderline:
- Check the destination country’s customs website for a prohibited and restricted items list.
- Ask your removals coordinator if you’re unsure about a specific item.
- Keep receipts or documentation for expensive electronics and jewellery.
- Declare everything honestly rather than guessing at a lower value to save on duty.
Under-declaring is one of the fastest ways to trigger an inspection and a penalty, since customs authorities routinely cross-check declared values against known market prices.
How Removals.co.uk Helps You Avoid the Delays
This is where using an experienced international removals company earns its keep. Removals.co.uk builds customs clearance into every overseas shipment rather than treating it as an extra step you’re left to sort out yourself. Each move comes with a dedicated coordinator who manages the process from the first quote through to delivery at your new address.
What that looks like in practice:
- Your coordinator handles customs clearance, terminal fees, and the shipping paperwork alongside the physical move.
- Packing is done in industry-approved materials, with an inventory built to match what customs authorities expect to see.
- Shared and sole-use shipping containers are both available, by sea or air freight, depending on your budget and timeline.
- Support runs around the clock, so questions about documentation don’t sit unanswered for days.
- Coordinators are familiar with the requirements for the destinations they ship to regularly, from Australia and the USA to most of Europe.
Booking six to eight weeks ahead gives enough lead time for relief applications and paperwork checks to be completed properly, rather than rushed through at the last minute. On busier routes or during peak season, that window can matter even more.
FAQs (Frequently Asked Questions)
1. How long does customs clearance usually take for an overseas move?
It varies by destination, but a straightforward shipment with complete paperwork typically clears within days. Missing documents or an unapplied relief scheme can add weeks.
2. Can I get help with paperwork instead of doing it myself?
Yes, most international removals companies, including Removals.co.uk, handle customs clearance and documentation as a standard part of the service rather than an optional extra.
3. What happens if my shipment gets flagged at customs?
It’s usually held for physical inspection until the paperwork issue is resolved, which can mean storage charges at the port until it’s released.
4. Does booking early actually reduce the risk of delays?
Yes, early booking gives time for any customs relief application to be approved before your goods travel, which is usually a requirement, not a formality.
