Customs brokerage explained: what does a customs broker do in the UK?

Customs brokerage means having a specialist prepare and submit your customs declarations and deal with HMRC for you. Here is what a UK customs broker actually does, how the representation types change who is liable, and which tasks you can never hand over.

What does a customs broker do? The short answer

A customs broker prepares and submits customs declarations for goods you import or export, and deals with the customs authority on your behalf. In the UK, GOV.UK rarely uses the word "broker" on its own. Its guidance talks about getting "someone to deal with customs for you" and groups the people who do this into three kinds of business: freight forwarders, which move goods internationally and arrange clearance; customs agents or brokers, which make sure goods clear customs; and express operators, which handle customs as part of a time-bound parcel or freight delivery. Other common labels for the same role are customs intermediary, customs agent and customs representative.

Customs brokerage, then, is the service of turning your commercial paperwork into a correct declaration and taking responsibility for submitting it. Exactly how far that goes depends, in HMRC's words, on the services the business offers, what you ask it to do and the commercial agreement between you. GOV.UK's step-by-step import guide notes that most businesses hire someone for this rather than doing it themselves.

Do UK customs brokers need a licence?

No. GOV.UK's guidance on appointing someone does not describe any licence for customs agents. What it does require is that the agent is established in the UK for customs purposes; since 1 January 2021 agents have had to be established in Great Britain or Northern Ireland. HMRC publishes a register of customs agents and express operators to help traders find one, but it states plainly that businesses on the lists are not vetted, approved or recommended by HMRC, and that the details come from the businesses themselves. Treat any claim of an official UK customs licence with caution, and check what a provider can actually show you.

The core tasks in customs brokerage

Classification

Every import declaration needs a commodity code. The code drives the duty rate and shows whether a licence is needed. GOV.UK puts the job of finding the right code on the person importing or exporting, and acknowledges that classification can be complicated, which is why it points traders towards getting someone to deal with customs for them. A good broker will ask detailed questions about what the goods are made of and what they are used for, rather than guessing from the invoice description.

Valuation and duty relief

The declaration must also carry the value of the goods so that duty and import VAT can be calculated. A broker works out which figures belong in the customs value and whether you may pay less or no duty, for example because the UK has a trade agreement with the country the goods come from, or because a duty suspension or tariff quota applies. The evidence for any preference claim still has to come from you and your supplier.

Declarations in CDS

UK import and export declarations are made on the Customs Declaration Service (CDS), the system that replaced CHIEF; HMRC no longer lets anyone continue using the older system. Declarations go in through customs software, so most traders rely on a broker's software and experience rather than buying their own. If you want to see what an import entry involves line by line, our guide to CDS import declarations walks through it, and the glossary has a short definition of CDS.

Choosing the type of representation

When an agent acts for you, the written instructions must say whether it acts as your direct or indirect representative. This is not a formality, because it decides who is liable:

• Direct representation: the agent acts in your name. You are solely liable for the customs debt, for keeping records and for the accuracy of the declaration. The agent can become jointly and severally liable only if it makes a deliberate or unreasonable error after you gave clear instructions.
• Indirect representation: the agent acts in its own name on your behalf. You and the agent are jointly and severally liable, and HMRC may seek payment from either of you.

Two limits are worth knowing. Businesses not established in the UK that import into Great Britain can only use indirect representation. And HMRC guidance says indirect representation cannot be used for inward processing, outward processing, temporary admission, authorised use or private customs warehousing.

Paying duty and import VAT

Before you appoint anyone, HMRC suggests agreeing whether you will have your own duty deferment account for payments or whether the agent will use theirs. If you have an account, CDS lets you give someone immediate authority to use your duty deferment, cash or general guarantee account, so the broker can use your account when it submits declarations for you.

Liaison with HMRC and other paperwork

HMRC's checklist also lists safety and security declarations and transport arrangements as responsibilities to settle up front, along with how the agent copes with time-sensitive goods, out-of-hours changes and unforeseen problems. If your goods need a licence, certificate or special handling, check that the broker can deal with them.

What stays your responsibility

Appointing a broker does not hand over the whole job. GOV.UK is explicit that you remain responsible for due diligence on your customs declarations. In practice that means:

• giving the broker your EORI number (a GB EORI for goods entering England, Scotland or Wales);
• supplying evidence of the goods, such as invoices or contracts, and an accurate description;
• providing any licences or certificates that restricted goods need, plus anything else the broker asks for;
• keeping records, including commercial invoices, customs paperwork and your import VAT certificate (C79);
• checking the declaration data the broker sends back, especially under direct representation where you carry the liability.

Customs brokerage for UK–EU trade

Goods moving between Great Britain and the EU need customs formalities on both sides of the border, so a single shipment can involve an export declaration in one country, an import declaration in the other and, for road freight, often a transit movement in between. Some brokers handle only the UK side; others work with partners or have their own team in the EU. If you trade with Poland in particular, it is worth reading about what to expect from a UK–Poland customs broker before you ask for quotes.
