If you import goods into the UK, getting the correct HS codes UK classification can affect your customs declaration, import duty and clearance process. The right code helps HMRC identify what you are importing and determine the applicable customs treatment.
What Is an HS Code?
An HS code is part of the Harmonized System used internationally to classify traded products. The system provides a common structure for identifying goods across international markets.
The UK uses commodity codes for customs purposes. These codes build on the international HS structure and provide additional digits for UK customs requirements.
For UK importers, the correct classification matters because the commodity code can determine the applicable duty rate, import controls and other requirements.
You can check the current UK classification and tariff information using the official UK Trade Tariff.
HS Codes vs UK Commodity Codes
HS codes and UK commodity codes are related, but they are not exactly the same.
The international HS system generally uses six digits. The UK commodity code contains additional digits to provide more detailed classification for customs purposes.
For example, a business may know the six-digit HS code for a product but still need to identify the full UK commodity code before completing an import declaration.
This is why HS code lookup UK searches should lead to the specific UK commodity code rather than stopping at the international six-digit classification.
How to Find the Correct HS Code in the UK
Finding a commodity code starts with understanding exactly what the product is.
Consider these details before searching:
- What is the product made from?
- What is its main function?
- How is it manufactured?
- Is it a finished product, component or raw material?
- Does its size, composition or intended use affect classification?
You can then search the UK Trade Tariff using the product description and review the available classifications.
Do not choose a code simply because the description appears similar. Read the relevant classification information and check whether the product meets the conditions attached to that code.
Why Correct Classification Matters
A commodity code does more than identify a product. It can affect the customs duty payable and whether additional import requirements apply.
For example, consider a UK retailer importing ceramic kitchenware. The importer finds a similar product online and selects its commodity code without checking the full classification details.
If the chosen code is incorrect, the customs declaration may contain inaccurate information. This can lead to additional customs work, delays or an adjustment to the amount payable.
The correct approach is to classify the actual product based on its characteristics, rather than selecting a code based only on its name.
How HS Codes Affect Import Duty
Your import duty HS code is directly relevant to determining the customs treatment of imported goods.
However, the commodity code is only one part of the calculation. The origin of the goods and their customs value can also affect the amount payable.
This means two similar products may not always receive identical customs treatment.
Before shipping, check the commodity code, country of origin and customs value. You can also review the duty information through the UK Government Trade Tariff service.

Common HS Code Mistakes UK Importers Make
Small classification mistakes can create unnecessary customs problems. Common issues include:
Using the supplier’s code without checking it
An overseas supplier may use a classification that does not match the UK’s requirements.
Searching by product name alone
Product names can be broad. Material, function and construction may affect classification.
Ignoring the full commodity code
The international HS code may not provide enough detail for a UK import declaration.
Using an old classification
Tariff information can change, so importers should check the current UK tariff before shipping.
Guessing when the product is complex
Specialised products may require more detailed classification research.
How Can Importers Improve Product Classification?
A simple classification process can reduce errors before goods leave the supplier.
- Create a product specification sheet.
Record the material, function, composition and intended use. - Check the UK commodity code before ordering.
Do not wait until the shipment reaches the UK. - Compare the classification with your supplier’s information.
Investigate differences instead of automatically choosing one code. - Keep classification records.
Store product specifications and the reasoning behind your selected code. - Review classifications when products change.
A change in material, design or function may affect classification.
For businesses importing regularly, accurate product classification should form part of the wider customs compliance process.
What If You Cannot Find the Right Commodity Code?
Some products are difficult to classify because they contain several materials or have multiple functions.
In these cases, avoid guessing. Review the relevant UK tariff information and seek specialist customs advice where necessary.
Businesses can also consider applying for a UK Binding Tariff Information decision where appropriate. This can provide a legally binding classification decision for a specific product under the relevant conditions.
Accurate classification also supports a smoother customs clearance process. For more guidance, read NKR Freight’s Customs Clearance Process UK Imports.
Conclusion
Understanding HS codes UK requirements is an important part of importing goods into Britain. The correct UK commodity code helps you identify the applicable customs treatment and prepare accurate import declarations.
Do not rely solely on a supplier’s classification or a product name. Check the current UK Trade Tariff, document your product characteristics and review the classification whenever the product changes.
For regular importers, getting classification right before shipment can help reduce avoidable customs problems and make landed-cost calculations more reliable.
Frequently Asked Questions
What is an HS code in the UK?
An HS code is part of the international product classification system. UK customs uses commodity codes based on this system to classify imported and exported goods.
How do I find an HS code in the UK?
Use the UK Trade Tariff and search for your product. Review the available classifications carefully and select the commodity code that matches the product’s characteristics.
Are HS codes and commodity codes the same?
Not exactly. HS codes provide the international classification structure, while UK commodity codes provide additional detail for UK customs purposes.
Can the wrong HS code affect import duty?
Yes. The commodity code can affect the customs duty treatment applied to imported goods. Other factors, including origin and customs value, can also affect the amount payable.
Can I use my supplier’s HS code?
You can use it as a starting point, but you should verify the classification against UK requirements. The overseas supplier’s classification may not provide the correct UK commodity code.
What should I do if I cannot classify my product?
Check the UK Trade Tariff and review the product’s material, function, composition and intended use. For difficult classifications, consider obtaining specialist customs advice or applying for a Binding Tariff Information decision where appropriate.
