Customs Broker UK – What Do They Really Do?

Thinking about hiring a customs broker in the UK? Whether you're a new importer or scaling your logistics, understanding the true role of a customs broker can save you time, money, and compliance headaches. In this article, we'll explain what a UK customs broker actually does, when you need one, and how to choose the right partner for your business.

What Is a Customs Broker?

A customs broker is a licensed intermediary who helps businesses navigate the complexities of importing and exporting goods through UK customs. Unlike HMRC officials, brokers work on your behalf to ensure your shipments comply with UK regulations — including declaration submission, tax calculation, and goods classification.

Customs brokers have access to systems like CDS (Customs Declaration Service) and CHIEF (now being phased out), which are used to submit import and export declarations electronically.

When Do You Need a Customs Broker?

Hiring a broker isn't mandatory, but it's often highly recommended if:

• You're new to international trade or customs declarations
• You're importing/exporting goods regularly
• You're dealing with regulated goods (food, electronics, chemicals, etc.)
• You don’t want to risk delays, rejections or fines

Even experienced importers rely on brokers to save time, ensure accuracy, and stay compliant with ever-changing regulations.

“A good customs broker won’t just fill out a form. They’ll be your trade partner, compliance guardian, and logistics safety net.”

What Does a Customs Broker Actually Do?

Here’s what a professional UK customs broker like Customs Flow Declare typically handles:

• Prepare and Submit Declarations

Using your commercial invoice and shipment details, the broker submits accurate import/export declarations to HMRC via CDS.

• Calculate Duties and VAT

Your broker ensures that duties, tariffs, and VAT are calculated correctly and applied using your EORI number.

• Classify Goods with Correct HS Codes

Misclassification can lead to overpaying duties or delays. A broker identifies the right HS codes based on product type and trade agreements.

• Manage Border Requirements (e.g. GMR, PBN, IPAFFS)

They handle key border documentation like the Goods Movement Reference (GMR) for RoRo transport, or IPAFFS for importing products of animal origin.

• Liaise with Freight Forwarders & Port Authorities

Your broker communicates with hauliers, forwarders, and UK port systems to ensure your goods move without delays.

• Resolve Rejections and Amendments

If something goes wrong (and it often does), your broker steps in to resolve declaration errors or make urgent amendments.

Customs Broker vs Freight Forwarder – What’s the Difference?

While both play vital roles in cross-border logistics, they are not the same:

• A freight forwarder moves your goods from A to B
• A customs broker ensures your goods are allowed to enter or leave the UK legally and compliantly

Some companies offer both services, but always clarify who handles your customs clearance.

How to Choose the Right Customs Broker in the UK

Here are 5 things to look for:

1. Experience & Licensing – Are they registered with HMRC and experienced in your type of goods?
2. Responsiveness – Do they reply quickly and clearly?
3. Transparent Pricing – Flat fees or hidden extras?
4. Speed of Turnaround – Especially for time-sensitive shipments
5. Custom Support – Can they assist with documents, classification and special requests?
