A customs warehouse is one of the most important cost optimisation tools in international trade. It enables the storage of goods imported from outside the UK without the need to immediately pay customs duty and import VAT. In this article, we explain how this procedure works, who can use it and what conditions are required to obtain a licence from HMRC.

Definition and legal basis for customs warehouses

In accordance with GOV.UK guidance on customs warehouses, a customs warehouse is an HMRC-approved location where goods from outside the UK can be stored under suspension of customs duties and import VAT. UK customs law following Brexit is based on the Customs (Import Duty) Act 2018 and implementing regulations, which allow for the application of special procedures, including customs warehousing.

The customs warehouse procedure is regulated by HMRC and requires formal approval. Management of customs warehouses by an experienced customs broker ensures compliance with legal requirements and proper maintenance of goods records.

How customs warehouses work — the suspension mechanism

The customs warehouse mechanism operates on the basis of suspension (not cancellation) of customs duties and taxes. This means goods can be imported into the UK and placed in a customs warehouse without immediate payment of duty. The liabilities are only required when one of the following events occurs:

• Release for free circulation — the goods enter the UK market and become subject to full duties;
• Re-export — goods leave the UK without paying UK customs duties (ideal for distributors and logistics companies);
• Customs processing — goods can be subjected to a manufacturing process before final use;
• Destruction or abandonment — in specific cases, goods may be destroyed without assessment of duties.

Types of customs warehouses in the UK

In the United Kingdom, there are two main types of customs warehouses:

• Public Warehouse — operated by a commercial operator, available to multiple importers. The operator (licence holder) is responsible for compliance with the procedure conditions.
• Private Warehouse — intended exclusively for goods of a specific importer/owner. The owner is solely responsible for meeting requirements and maintaining records.

Financial and logistical benefits

Customs warehousing offers numerous significant benefits for importers and distributors:

• Cash flow optimisation — customs duty and VAT are paid only upon actual sale or distribution of goods, not upon import;
• Logistics flexibility — ability to consolidate shipments and distribute according to market needs;
• Re-export efficiency — goods destined for third-country markets can transit through the UK duty-free;
• Seasonal risk management — importing at favourable times without the need for simultaneous financial burden.

For companies importing large quantities of goods, the ability to manage customs clearances using modern customs platforms integrated with customs warehouse record-keeping systems is particularly valuable.

Conditions and requirements for obtaining HMRC approval

Obtaining approval to operate a customs warehouse requires compliance with the following conditions:

• Possession of an active EORI number (Economic Operators Registration and Identification);
• Availability of appropriate warehouse facilities enabling identification and recording of customs goods;
• Implementation of a goods record system (stock records) meeting HMRC requirements;
• Demonstration of financial capability to cover potential customs liabilities (customs guarantee may be required);
• Absence of a history of serious breaches of customs regulations.

Record-keeping and HMRC controls

The operator of a customs warehouse is obliged to maintain detailed records of all goods — from the moment of warehouse receipt, through all operations (such as repackaging, sorting), until release or re-export. HMRC has the right to conduct audits and inspections at any time. Discrepancies in records may result in withdrawal of approval and assessment of suspended liabilities.

Customs warehouse and other special procedures

It is worth distinguishing a customs warehouse from other special procedures available in the UK, such as inward processing relief (IPR), which allows for the processing of imported goods duty-free, on condition of re-export of finished products. Both procedures can be applied together depending on the importer’s business model.
