Authorised Use (End Use): What UK Importers Need to Know

UK customs procedures can appear complex, but understanding the correct declaration method can make a meaningful difference to both compliance and landed costs. One procedure that is often overlooked is Authorised Use (previously known as End Use).

This article provides a straightforward overview of what Authorised Use is, when it applies, and how importers can determine whether their goods may qualify.

What is Authorised Use?

Authorised Use is a UK customs procedure that allows importers to pay a reduced or zero rate of import duty when goods are imported for a specific approved purpose and used within a defined period.

HMRC refers to these qualifying purposes as a “prescribed use.” Only certain commodities, imported for clearly defined uses, are eligible. Once goods are declared under Authorised Use, compliance is monitored to ensure they are used correctly and within the required timeframe.

Where is Authorised Use commonly applied?

The procedure is most frequently used in specialised sectors where imported goods serve a defined operational purpose, including:

• Aerospace and aircraft parts

• Marine and ship work

• Military and defence-related goods

• Oil and gas equipment

• Certain food products such as cheese, fish, and prawns

Eligibility depends on both the commodity code and the intended use of the goods.

How can Authorised Use be obtained?

There are two main routes depending on how often the procedure is required.

Full authorisation (regular importers)

UK‑established businesses importing qualifying goods regularly can apply to HMRC for ongoing authorisation, allowing consistent use across shipments.

Authorisation by declaration (occasional use)

For less frequent imports, Authorised Use may be applied directly on the customs declaration (subject to conditions):

• Typically limited to 10 uses per year

• Individual shipment values up to £500,000

This option is often suitable for occasional or project-based shipments.

Can it be applied retrospectively?

In some circumstances, importers may submit retrospective claims to reclassify previously imported goods under Authorised Use. This generally requires holding — or applying for — full authorisation, including where a previous authorisation has lapsed.

How to check if your goods qualify

Eligibility can usually be identified within the UK Integrated Online Tariff:

1. Locate the relevant commodity code.

2. Review the duty details.

3. Check the notes section (often under “Suspensions”) for references to Authorised Use.

Because tariff interpretation can be technical, many businesses review eligibility before shipment to avoid post‑clearance corrections.

Why it matters

When applied correctly, Authorised Use can help businesses:

• Reduce import duty exposure

• Maintain compliance with HMRC requirements

• Avoid unnecessary amendments or delays after clearance
