Understanding UK Commodity Codes: HS Codes and TARIC Classification

What Is a Commodity Code?

A commodity code is a numerical classification assigned to goods for customs purposes. It tells HMRC — and customs authorities worldwide — exactly what type of goods you are importing or exporting.

In the UK, commodity codes are based on the Harmonised System (HS), an international classification system developed by the World Customs Organisation (WCO) and used by over 200 countries. The UK then extends these codes for more specific national purposes in the UK Global Trade Tariff (GTT).

How Commodity Codes Are Structured

UK commodity codes are 10 digits long and follow this structure:

Digits 1–6: The HS code (internationally standardised)
Digits 7–8: The Combined Nomenclature (CN) code (UK/EU level)
Digits 9–10: National additional codes (UK-specific)

For example: 6203 42 11 00 would refer to a specific type of men's trousers made of cotton.

Why Commodity Codes Matter

The commodity code you use on a customs declaration has direct consequences:

1. Duty Rate Each commodity code has an associated duty rate in the UK Global Trade Tariff. Applying the wrong code could mean paying more duty than necessary — or, worse, underpaying and facing penalties.

2. VAT Treatment Certain goods attract a reduced rate of VAT or are VAT-exempt. The commodity code determines which applies.

3. Import Controls and Licences Many commodity codes trigger import controls. For example:

Food products may require licences from APHA (Animal and Plant Health Agency)
Chemicals may require REACH compliance
Textiles from certain origins may be subject to quotas
Dual-use goods (with both civilian and military applications) require export licences

4. Anti-Dumping and Safeguard Duties Some goods are subject to additional anti-dumping or safeguard duties. These apply to specific commodity codes for goods from specific countries.

5. Trade Statistics HMRC uses commodity code data for UK trade statistics. Accurate coding ensures your trade data contributes correctly to national trade figures.

How to Find the Right Commodity Code

The UK Government's Trade Tariff tool (available at trade.gov.uk) allows you to search for commodity codes by description. However, finding the correct code is not always straightforward:

Descriptions can be ambiguous
The same item may qualify under multiple codes depending on its composition or intended use
Codes are updated periodically

For non-trivial goods, it is advisable to seek expert classification support. Customs Clearance 24 provides professional goods classification services, ensuring every shipment uses the correct code from the outset.

Binding Tariff Information (BTI)

If you regularly import a specific type of goods and want legal certainty about the correct commodity code, you can apply to HMRC for a Binding Tariff Information (BTI) ruling. A BTI is a legally binding decision from HMRC confirming the correct code for your goods.

BTI rulings are valid for 3 years and provide protection if HMRC later disagrees with your classification. Customs Clearance 24 can assist with BTI applications.

The Cost of Getting It Wrong

Incorrect commodity classification is one of the most common causes of customs compliance problems for UK importers. The consequences can include:

Overpayment of duty: If you use a code with a higher duty rate than correct
Underpayment and penalties: If you use a code with a lower duty rate, HMRC can demand the difference plus interest and penalties
Delay at the border: If your code triggers a licence requirement you were not expecting
Seizure of goods: In the most serious cases, incorrectly classified controlled goods can be seized
