Understanding End-Use (Authorised Use) Customs Procedure

End use is one of the UK and EU’s special customs procedures, alongside inward processing, customs warehousing, and temporary admission. Under it, traders can import eligible goods at a reduced or zero rate of duty, provided the goods are used for the purpose the tariff prescribes. Terminology has diverged since Brexit: the EU continues to use “End Use,” while UK authorities formally renamed the procedure “Authorised Use” from 1 January 2021. Most UK traders still refer to it as End Use in practice, and the two terms describe the same underlying mechanism.

What Makes Goods Eligible

Eligibility is not general. The UK Integrated Online Tariff lists, commodity code by commodity code, which goods qualify for End Use and what the prescribed use is for each. A product does not become eligible because it resembles a listed category. The specific tariff entry must apply to the specific commodity code under which the goods are classified, and the notes attached to that entry, frequently found under a “Suspensions” heading in the Tariff, set out the exact conditions attached to the relief.

Sectors where End Use appears most frequently include aerospace, shipbuilding, and defence, alongside categories such as scientific instruments and certain agricultural and fisheries products. In each case, the relief exists to support a defined economic or policy objective, not simply to reduce the cost of importation, and that objective is precisely what the authorisation and discharge conditions are designed to verify.

Authorisation: The Precondition for Relief

A trader cannot use End Use by declaring it at import. Authorisation must be held from customs authorities before the relief can be claimed, and it takes one of two forms depending on the volume and frequency of use.

Businesses that import qualifying goods regularly can apply to HMRC for a standing authorisation, allowing consistent use of the procedure across shipments without a fresh application each time. For occasional or low-frequency use, typically up to three imports within a calendar year for straightforward operations, the procedure can instead be applied for directly on the customs declaration itself, using form SP1, without a prior standing authorisation. This simplified route cannot be combined with simplified declaration procedures such as CFSP, and is not available for goods valued above £500,000.

Where goods will be processed or move through more than one EU member state, a separate cross-border authorisation is required for the EU leg of the movement. A single UK authorisation does not extend that reach automatically.

The Conditions That Must Be Met

Holding an authorisation is the starting point, not the end of the compliance obligation. Four conditions run for the life of the goods under the procedure.

The goods must be put to the prescribed use set out in the authorisation, and this must happen within the time limit stated in that authorisation, not at the trader’s own discretion. A guarantee must generally be provided to cover the duty that would otherwise be due, protecting the revenue position if the conditions are not ultimately met. Adequate records must be kept in an approved form, sufficient to demonstrate at any point that the goods remain within the procedure or have been properly discharged from it. And the goods must remain available for customs supervision throughout, meaning their location and status must be traceable on request, not merely assumed.

Where goods move between operators before being put to their prescribed use, for example between different sites within the same authorisation or under a transfer of rights and obligations, every operator receiving End Use goods must be named in the authorisation in advance of the movement. An unrecorded transfer is not a minor administrative gap. It breaks the chain of accountability the procedure depends on.

Discharge: How the Procedure Concludes

Goods remain under End Use provisions from the point of import until they are formally discharged, and discharge happens in one of three ways: the goods are put to the prescribed use listed in the tariff within the authorised time limit, they are moved to another customs procedure, or they are destroyed under customs supervision.

The bill of discharge is the document that evidences which of these occurred, and it must show that the goods were used as prescribed or that the procedure was otherwise properly closed. Where the bill of discharge cannot demonstrate this, and where the goods cannot be shown to have been put to the prescribed use within the required period, duty becomes due on the goods as though the relief had never applied. The relief that appeared to reduce the landed cost at the point of import is not a permanent saving until discharge is properly evidenced. Until then, it is a conditional and reversible position.

Where End Use Fits Into Duty Optimisation

End use is one of the four levers available within a broader duty optimisation strategy, alongside classification, preferential origin, and customs valuation. Used correctly, it delivers a genuine reduction in the dutiable cost of qualifying goods. Used without the administrative discipline the authorisation demands, whether through late discharge, unrecorded transfers, or inadequate record-keeping, it does not merely fail to deliver the anticipated saving. It creates a duty liability that surfaces retrospectively, at the point an audit or a discharge review exposes the gap between what the authorisation required and what was actually demonstrated.

The businesses that use End Use relief most reliably are not those with the highest volume of qualifying imports. They are those with the clearest internal ownership of the authorisation’s conditions, the most consistent record-keeping against the discharge requirement, and a defined process for confirming that goods have been put to their prescribed use before the authorised time limit expires, rather than discovering the gap when HMRC asks.
