The Short Answer
A customs broker submits your HMRC import declaration. A freight forwarder moves your cargo. In practice, most established UK logistics companies do both, so for most importers, the distinction does not matter. What does matter is confirming your provider holds HMRC authorisation to act as your customs representative.
Customs Broker: What They Do
A customs broker (also called a customs agent or customs intermediary) is a specialist whose primary function is to interact with HMRC on your behalf. In the UK post-Brexit, that means submitting import and export declarations via HMRC's Customs Declaration Service (CDS).
Specifically, a customs broker:
- Classifies your goods with the correct 10-digit commodity code (CN code)
- Calculates import duty, anti-dumping duty, and any trade preference claims
- Submits the import declaration to HMRC electronically via CDS
- Obtains the customs release ("out of charge" notice) so your cargo can leave the port or airport
- Manages duty payment or deferment through your duty deferment account
- Files any post-entry amendments or supplementary declarations if required
A customs broker does not typically book your shipping, manage your cargo at the port, or arrange inland delivery, unless they also operate as a freight forwarder.
Freight Forwarder: What They Do
A freight forwarder organises the physical movement of your cargo. They act as an intermediary between you (the importer or exporter) and the carriers, shipping lines, airlines, road hauliers, and rail operators.
Specifically, a freight forwarder:
- Books container space (FCL or LCL) with shipping lines, or cargo space with airlines
- Arranges collection from the supplier's premises at origin
- Manages bills of lading, air waybills, and other transport documents
- Coordinates port or airport delivery and terminal handling
- Arranges cargo insurance
- Manages onward inland delivery to your premises in the UK
A freight forwarder does not automatically submit HMRC import declarations, unless they also hold customs agent authorisation.
Side-by-Side Comparison
| Customs Broker | Freight Forwarder | |
|---|---|---|
| Primary role | Submit HMRC declarations | Move cargo |
| HMRC authorisation | Required, direct or indirect representative | Not required for freight; required if also filing declarations |
| Licensing | No specific UK licence, but HMRC registration + CDS access required; BIFA membership voluntary | No licence required in the UK (unlike some countries) |
| Books shipping | No (unless dual-role) | Yes |
| Files HMRC declarations | Yes | Only if also customs-authorised |
| Manages port handling | Partially (coordinates with terminal) | Yes |
| Arranges inland delivery | Sometimes | Yes |
| Typical fee | £30-£150 per import entry | Freight rate + THC + delivery; clearance sometimes included |
| Gxpresss | Both, full-service freight forwarding + free customs clearance at Heathrow | |
The Legal Distinction: Direct vs Indirect Representation
When a customs agent files a declaration on your behalf, they must declare their representation type to HMRC:
- Direct representative: Acts in your name, you retain full legal liability for any duty errors or underpayments. The agent's liability is limited.
- Indirect representative: Acts in their own name, both you and the agent are jointly liable. This is common for freight forwarders who bundle clearance into their service.
For most standard commercial imports, the distinction is academic. It matters if there is a duty dispute or post-clearance audit: under direct representation, HMRC will pursue you; under indirect, they can pursue either party. Ask your agent which model they use.
One Company for Both, No Handover Gap
Gxpresss handles freight forwarding and customs clearance under one roof. No coordinating between a forwarder and a separate broker. One invoice, one contact, same-day release at Heathrow.

Most of the time, a full-service freight forwarder who holds HMRC authorisation covers both roles. However, you may need a specialist customs-only broker in these situations:
- You already have a freight forwarder who doesn't offer clearance, add a customs agent to submit declarations
- You ship via DDP Incoterms, your supplier delivers to the UK with duty paid; you may still need to verify the declaration is correct and use the right importer of record
- Controlled or licenced goods, CITES, dual-use, SPS, or import-licenced products benefit from an agent who specialises in that category
- Post-clearance audits, if HMRC queries a past import, a customs specialist handles the response; a transport-focused forwarder may not
- Binding tariff rulings, if you want a formal ruling from HMRC on a commodity code, a specialist broker is better placed to prepare and submit it
Does It Matter Which Term You Use?
Not for most importers. The practical checklist is:
- Does your provider hold HMRC authorisation to submit CDS declarations? (If no, they can not legally file your entry.)
- Do they book the freight too, or do you need a separate carrier arrangement?
- Do they handle port-side coordination and inland delivery, or is that a separate cost?
- What is their fee structure, per entry, bundled, or retainer? (See our broker fee guide →)
A provider who answers yes to all four is effectively both a customs broker and a freight forwarder. That is the model Gxpresss operates on.
