Dual-use goods are products, technologies and software that can be used for both civilian and military purposes. Exporting them outside the EU, and between the UK and the EU, is subject to additional controls and requires a licence issued by the relevant export control authority (in the United Kingdom — the ECJU), on top of the standard customs declaration. Not holding the required export licence for a good classified as dual-use is a breach of the regulations, even if the customs clearance itself goes through without issue.

How to prepare the process and documents
Division of responsibilities between the parties
Minimum data set for the declaration
A correct declaration for dual-use goods requires: an EORI number, the CN/TARIC code together with the export control annotation, a customs value matching the invoice, the country of destination, and the export licence number, if one is required. This keeps the process repeatable and resistant to mistaken interpretations drawn from unofficial sources.

How to stay compliant and keep your records in order
Staying compliant in the area of dual-use goods requires regular internal reviews, keeping the tariff classification up to date, and checking the status of any export licences held. Systematic audits make it possible to spot gaps before a formal official inspection takes place.
Archiving, corrections and evidence of due diligence
Documentation should include: the original commercial invoices, transport documents, copies of declarations submitted, correspondence with the customs office, and proof of payment of customs duty and tax liabilities. If a declaration needs to be corrected, every version of the document should be kept together with a written justification for the change. Evidence of due diligence is essential in the event of an inspection or a dispute with the customs authority.
Working with a customs agency and internal audit
Regular internal audits make it possible to identify recurring classification errors and documentation gaps before a formal inspection. Working with an experienced customs agency that specialises in dual-use goods gives you access to up-to-date guidance and practical support when applying for export licences. It's worth setting a schedule of quarterly compliance reviews and assigning someone to monitor regulatory changes.
Summary
In summary: when it comes to dual-use goods, the key is to run the process according to current official guidance, with a clear division of responsibilities and documentation of every decision. This approach reduces delays, cuts the number of corrections needed and makes it easier to defend your figures during an inspection. If any requirement is unclear, check the current GOV.UK or KAS guidance before submitting the declaration.

Frequently asked questions
What are dual-use goods, and why do they need a special customs procedure?
Dual-use goods are products, software or technologies that can be used for both civilian and military purposes. Because of the risk that they could be used in weapons programmes, they are subject to export controls under EU Regulation 2021/821 and the UK Strategic Export Control Lists. The exporter must obtain the appropriate licence and keep detailed records of every transaction.
What documents are required when exporting dual-use goods from the United Kingdom?
The documents required are: an export licence (SIEL or OIEL) issued by the ECJU (Export Control Joint Unit), a commercial invoice with the CN/TARIC code and export control annotation, a packing list, an end-user certificate (EUC) from the end recipient, and an export declaration submitted through the CDS system. Missing any of these documents can result in the shipment being held at the border.
How can you check whether a given item needs a dual-use export licence?
You need to check the item's CN code against the list of controlled goods — the UK Strategic Export Control Lists or Annex I to EU Regulation 2021/821. If the item appears on the list, the appropriate licence is required. If there's any doubt about the classification, you can submit a Rating Request to the ECJU (UK) or the relevant national authority in the EU.
What are the consequences of misclassifying a dual-use item?
Misclassification can result in the shipment being held by customs, substantial financial penalties and, in serious cases, criminal liability for the unlawful transfer of controlled technology. Verifying the classification with an export control specialist before every transaction is therefore a key part of risk management.
How can a customs agency help a company handle dual-use goods?
An experienced customs agency specialising in dual-use goods can help with classifying goods, putting together the licensing documentation, submitting export declarations and keeping the records required by law for at least five years. The agency can also represent the exporter during an official inspection and advise on choosing the optimal customs procedure, reducing the risk of costly operational mistakes.
