A UK tariff code is a unique number assigned to products that helps classify them for customs purposes, ensuring that the right taxes, duties, and fees are applied.
In this guide, we’ll explain everything you need to know about UK tariff codes, from why they matter to how you can easily find a tariff code. If you’re new to the world of importing and exporting or if you’re starting a haulage company, we’ve got you covered with clear and straightforward info to get you on track.

Why tariff codes matter for trade
Tariff codes are the backbone of international trade; without them, customs wouldn’t know what your goods are, what duties to charge, or if your goods need special permits.
If you get your tariff code wrong, you could face delays, problems with customs clearance, or get charged the wrong amount. That means paying too much or, even worse, not getting your goods through at all.
If you want to avoid mistakes like that, your first move is finding a tariff code that fits your product properly and lines up with how duties are applied (this ties closely to how import tax and customs duties are worked out in the UK).
Once you’ve got the right UK tariff code, your goods move through the system more smoothly, and you’re not caught off guard by extra costs or admin.
Understanding the harmonised system (HS)
The Harmonised System (HS) is a globally standardised way of classifying goods. It forms the foundation for tariff codes used around the world, including in the UK.
Every product traded internationally is assigned an HS code, which helps customs authorities identify what the item is, apply the correct duties, and monitor trade statistics.
HS codes are recognised in over 200 countries and used by more than 98% of international trade. So, getting familiar with the HS system is key if you want your goods to move across borders without issues.
HS code format and UK commodity code details
The HS code is always six digits long. The first two digits show the broader category of the product, while the next four digits narrow it down.
In the UK, the code is extended by another four digits to make a total of ten digits. This extra detail helps classify the product even more precisely for customs.
Let’s take an example: imagine you’re importing shoes. The HS code for footwear could be something like 6403, which would tell customs that it’s a particular type of shoe.
But the UK might add extra digits (say 6403 91 10) which would give even more info about the material and purpose of the shoes. This is where you can see the difference between the HS code and the commodity code, as the latter is more specific to the UK.
Main methods for finding tariff codes
Finding the right UK tariff code doesn’t have to be hard, but it does depend on the type of goods you’re working with. Below, we’ll go through some easy ways you can find a tariff code and get your products moving through customs without any hassle.
Let’s break it down and look at the different methods you can use to get the code you need for your goods. First off:
Option 1: Use the UK trade tariff online tool
One of the easiest ways to find a tariff code is by using the UK trade tariff online tool. This free tool lets you search for your product and quickly pull up the right code.
All you need to do is type in a description of your product! Then, the tool will give you the UK tariff code based on that.
It’s really straightforward to use, and it’s the first place you should go when you’re trying to figure out which code fits your product. If you’ve got a basic understanding of your goods, this tool can help you narrow down your options in no time.
Option 2: Email HMRC classification enquiries
If the online tool doesn’t cut it, or if you’re dealing with a more complex product, you can email HMRC for a classification enquiry.
HMRC will help you figure out the right tariff code based on a more detailed description of your goods.
While this might take a bit longer than using the online tool, it’s a great way to get certainty when you’re unsure about where your product falls in the tariff system. Freight forwarders also often have experience dealing with HMRC and can help you get the correct classification for your product.
Option 3: Search via sections, chapters, or A-Z index
Another way to find a tariff code is by browsing through the UK tariff book, either via sections or chapters. This allows you to see how different products are classified based on their type or function.
The A-Z index can also be helpful for a quick look-up. While this method is a little more manual, it can give you a solid understanding of where your product fits in the tariff system and help you find the right code without relying on the online tool.
Option 4: Obtain an advance tariff ruling (ATR / ATI)
If you’re still not sure which tariff code applies, you can request an advance tariff ruling (ATR) from HMRC. This means you’ll submit your product details, and HMRC will officially tell you which code applies.
This is particularly useful if you’re dealing with a complex or unusual product. Once you’ve got your ATR, you’ll know exactly how your goods should be classified, giving you peace of mind when it comes to customs clearance.
Extra code types and declaration rules
In addition to the regular UK tariff codes, there are a few extra code types that apply in specific situations. These are typically for goods that fall under quotas, suspensions, or are exempt from VAT, and they require special tariff codes.
If your product is one of these, it’s important to use the correct code to avoid any issues with taxes or customs. When it comes to trade, getting the small details right is paramount, so don’t overlook these extra rules.
Combined nomenclature, TARIC and national extensions
The combined nomenclature (CN) and TARIC systems are used to classify goods in the EU. Parts of these systems still apply in the UK, especially for goods moving between the UK and EU.
These systems use extra digits to give more detail about products, especially for those subject to quotas or special duties.
In addition, the UK has its own national extensions that provide even more precise classifications. These are added on top of the HS and CN codes to provide clarity for goods with unique characteristics or special treatment.
Applying codes for quotas, suspensions, and VAT
Certain goods fall under special rules, such as quotas, suspensions, or VAT exemptions. For these items, you’ll need to apply specific codes to make sure you’re meeting the regulations.
For example, some products might be exempt from certain duties if they’re classified under specific quotas or suspensions.
To keep things running smoothly, always double-check whether your product falls under these special classifications, especially if you’re dealing with large haulage businesses that regularly handle this kind of trade.
Common errors and how to avoid them
- Using vague product descriptions: If your product description is too broad or unclear, you might land on the wrong code. Be as specific as possible when describing materials, use, and features.
- Relying on outdated codes: Tariff codes can change from year to year. Always check the most recent version of the UK trade tariff tool before filing any customs paperwork.
- Missing extra classification rules: Some goods require special codes for things like VAT relief, quotas, or suspended duties. Skipping these can result in delays or paying more than necessary.
- Stopping at the 6-digit HS code: The full UK code is ten digits, not six. If you don’t include the full code, your goods may not be processed correctly.
- Copying another company’s code: Just because a similar product uses a certain code doesn’t mean it applies to yours. Even small differences in material, design, or purpose can change the classification.
- Guessing instead of checking: Taking a shot in the dark to save time can lead to bigger issues later. If you’re unsure, contact HMRC for advice or use a freight exchange platform to connect with professionals who know the system inside out.
- Not updating the code when the product changes: If your product’s materials, use, or specs change, the tariff code might too. Always review the code whenever something about the product shifts.
