5 common UK & EU customs mistakes that can cost you time and money
When shipping into the UK and EU, goods must go through the correct customs procedures before they can legally enter the destination country and move on to their final-mile delivery.
However, customs compliance can be one of the most challenging parts of international trade - and getting it wrong can have consequences!
From delayed shipments to unexpected fines, even small errors can quickly escalate into costly and timely problems.
So, as a leading cross-border customs clearance provider, we thought we’d share five of the most common customs mistakes we see - and how they can be avoided!
1. Incorrect or missing customs documentation
Goods entering the UK and EU require customs paperwork!
Incorrectly completed documents - or missing paperwork altogether - can halt clearance and trigger inspections, leading to storage charges, demurrage fees and unnecessary delays.
Examples of incorrect customs documentation may include inaccurate commercial invoices, mismatched packing lists, missing or incomplete certificates of origin, incorrect product descriptions and incorrect HS code (more on this later).
How to avoid it:
We recommend diligently ensuring your goods’ documentation is complete, consistent and submitted on time.
You should also make sure to double-check that product descriptions, quantities, values and any other details align across every document.
If you aren’t able to confidently complete your customs documentation, you can instead seek support from a customs broker – like CCL!
2. Misclassification of goods (wrong HS codes)
Every product transported to the UK and EU must be assigned the correct Harmonised System (HS) code. These codes classify duty rates, taxes and whether additional licences or controls apply.
Using the wrong HS code can result in overpaying duties, facing penalties, triggering audits or causing clearance delays.
How to avoid it:
Product specifications, materials and their intended use all impact the correct HS code. To avoid misclassifying your goods, invest time in doing your research.
To find the correct HS code, you can use your destination’s official government trade website or a dedicated online HS code lookup tool for more details. Alternatively, you can seek expert advice for guidance.
3. Inaccurate duty, tax and value declarations
The customs value isn’t always just the price you paid for the goods!
It may include freight, insurance, assists, royalties or other additional costs depending on the Incoterms (international commercial terms) agreed.
Errors in valuation can lead to unexpected charges, shipment holds or compliance investigations. Over-declaring can also mean you’re paying more duty and tax than necessary - directly impacting your margins!
How to avoid it:
To prevent this, you should take time to understand what must legally be included in your customs value and ensure your calculations are correct before submission.
Incoterms are a shorthand that defines your responsibilities, costs and associated risks of exporting products. These can be reviewed for more assurance on what needs to paid.
If you’re unsure how to correctly calculate your duty, tax and customs value declarations, CCL can assess your shipment details, ensure the correct elements are included and submit accurate declarations on your behalf.
4. Ignoring import restrictions and licences
Beyond customs duty - every country has their own rules and regulations that you will need to adhere to!
Some goods require import licences, certificates of conformity, health and safety documentation or other regulatory approvals.
More specifically, in cross-border eCommerce, vendors and carriers must carefully assess a range of import and export conditions and restrictions to ensure full compliance.
Overlooking these requirements can result in seized shipments, fines or even rejection at the border.
How to avoid it:
To avoid getting caught up with overseas rules and restrictions, we recommend conducting market-research for your destination-country in the early stages of your supply chain planning.
This is especially critical if you’re shipping regulated goods such as food, chemicals, electronics or controlled products that are subject to safety or trade restrictions.
As cross-border logistics providers helping ship products into the UK and Europe, we have extensive knowledge of UK/EU regulations and can guide you through the requirements if needed.
5. Leaving customs too late in the shipping process
Many businesses prioritise transport arrangements and leave customs planning until the last minute.
This often results in rushed submissions, incomplete data and avoidable errors.
How to avoid it:
It’s important to integrate customs compliance into your logistics strategy from the very start of your supply chain planning.
Early preparation prevents last-minute disruptions, reduces the risk of shipment delays and avoids frustrating your customers who are waiting for their products.
