Why transit needs a guarantee
The whole point of a transit movement is that goods can travel under duty suspension. The cargo crosses borders without the duty and VAT being paid at each crossing; the financial liability is deferred until the goods clear customs at their final destination.
That deferral creates a risk for the customs authorities. If the goods never arrive — if they go missing en route, or are diverted onto the home market without being declared — the duties and VAT that were never paid become permanently uncollected.
To manage that risk, every transit movement must be backed by a financial guarantee equal to the duties and VAT at stake. That guarantee gives HMRC and EU customs authorities a way to recover the lost revenue if anything goes wrong.
Two ways to lodge a guarantee
Broadly, you have two options.
Lodge your own. As a trader or haulier, you can register with HMRC for your own transit guarantee — typically a Comprehensive Customs Guarantee (CCG). You arrange a bond with a financial institution, pay an annual premium, and tie up capacity equal to your peak transit exposure. This makes sense for very large operators with constant volume.
Use a broker's CCG. You move under your customs broker's guarantee. The broker holds the CCG, allocates capacity per movement, and discharges that capacity when the destination office closes the TAD. You pay a per-movement fee. This is what most operators use, because it removes the paperwork, the capital tie-up, and the administrative load of managing your own bond.
For context: lodging your own CCG involves a bank guarantee or insurance policy, an HMRC application that typically takes 8-12 weeks, an annual renewal, and reporting obligations. Using a broker's CCG involves sending us the invoice.
How our CCG works
We hold an HMRC-authorised Comprehensive Customs Guarantee sized to cover the kind of work we file every day. For each movement, we calculate the duty and VAT exposure based on the goods value, HS code and customs status. We then allocate a corresponding amount of cover from our CCG and embed the guarantee reference in the NCTS declaration. HMRC's system reads the reference, confirms the cover is valid, and accepts the declaration.
The cover sits "live" against that specific movement until the office of destination lodges its IE018 discharge message. At that point, the cover comes back into our pool and is available for the next movement. The whole cycle is automatic — no manual application, no per-movement bond.
What we monitor — and why it matters
A CCG only works as long as movements discharge cleanly. If a TAD goes missing or fails to close, the cover stays locked against that movement until the issue is resolved. In extreme cases — if HMRC's search procedure fails to locate the goods — the guarantee can be called up, meaning the full duty and VAT in suspense is drawn down.
That happens almost never, but it is the reason we watch every movement. Our NCTS desk tracks the IE006 (anticipated arrival) and IE018 (discharge) messages on every TAD we file. If a movement is silent past its expected arrival, we chase it before the search procedure escalates.
In practical terms: in five years of operation across the PCSL group, we have had zero guarantee call-ups. That is not luck — it is the result of treating discharge monitoring as a core operational task rather than an afterthought.
When to use ours vs. lodging your own
Use a broker's CCG (most operators):
- You file fewer than several hundred transit movements a year
- You want to avoid the capital tie-up of a bond
- You want flexibility — movement sizes vary and you don't want a fixed bond sitting idle
- You don't have an in-house customs team to manage the guarantee
Lodge your own CCG (large operators):
- You file thousands of movements per year
- You have a steady, predictable transit exposure
- You have in-house customs and finance teams to manage the bond
- The per-movement broker fee, multiplied by your volume, exceeds the annual cost of your own guarantee
For most hauliers, freight forwarders and SMEs, the broker route wins on every dimension. For a major international logistics provider, the maths can flip.
If you are unsure which side of the line you fall on, send us your annual transit volume and average movement value, and we will run the comparison for you. The answer is usually clear within a few minutes.
