Every product you import and export has a secret identity — a commodity code. Get it wrong, and everything else goes wrong. Duty, VAT, origin, prohibitions and restrictions… all of these trade aspects flow from this one number.
Put yourself in the shoes of a national government. Each year, billions of pounds worth of goods move into and out of your country. You need to collect the correct revenue, enforce safety controls, and track trade statistics. How do you manage all of this?
You classify everything into an 8‑to‑10‑digit code. This is the commodity code.
You may hear it referred to as the HS code, tariff code, commodity code or nomenclature code – but they all refer to the same thing: a universal system for categorising goods so that customs authorities can manage them consistently.
The organisation responsible for ensuring that the first six digits of all commodity codes are used globally is the World Customs Organization (WCO). They maintain the “Harmonized System (HS)”. Every participating country takes those six digits and adds their own national-level digits.
In the UK, we use:
- 8‑digit codes for export
- 10‑digit codes for import
All of these are contained within the UK Trade Tariff.
Why Commodity Codes Matter
Commodity codes determine:
- The duty rate you pay
- Whether import VAT applies
- Whether your goods need a licence
- Whether you can claim preferential origin
- Whether HMRC will stop or inspect your shipment
- What information needs to be communicated within the customs declaration
If the commodity code is wrong, everything downstream could be wrong.
How to Find a Commodity Code (Simplified)
The UK Government’s online search tool allows traders to browse and search commodity codes. Let’s look at an example.
Example: Importing Handkerchiefs
Imagine you’re a UK trader importing handkerchiefs for sale to domestic retailers.
You could simply search “Handkerchief” and find heading 6213. But to be thorough (which is always a good idea in international trade), you decide to browse the tariff manually.
- You begin with Section XI – Textiles and Textile Articles
- You then read the section notes and move to Chapter 62 – Articles of apparel and clothing accessories, not knitted or crocheted.
- The, you read the chapter notes and decide that Heading 6213 – Handkerchiefs best matches your goods.
- Finally, after reading the footnotes, you select commodity code 6213200090 for the correct commodity based on material and production: Handkerchiefs of cotton, not hand-made.
Final result for import: 6213200090
Based on the country being imported from, the tariff then shows:
- Duty rates
- VAT rates
- Certificates or licences required
- Any special conditions or requirements
- Any additional information your broker will need
This is a huge amount of useful information for you as the importer.
Important: Always read the section notes, chapter notes, and footnotes. They may exclude your goods and redirect you to a different part of the tariff.
Common Mistakes Made
Even experienced traders get classification wrong. The most common issues include:
- Using generic “other” codes
- Misclassifying mixed-material goods
- Copy/pasting old codes from previous shipments
- Ignoring section/chapter notes
- Relying solely on the supplier’s advice (the commodity code is your responsibility as the exporter/importer)
These mistakes cost traders money – and HMRC can issue penalties as such.
Quick Checks You Can Do
You don’t need to be a classification expert to sanity-check a commodity code.
Ask yourself:
- Does the code match the material?
- Does the code match the function?
- Does the duty rate look realistic?
- Do the section/chapter/footnotes exclude your goods?
- Does the goods description support the code?
If something feels off, ask for assistance from an experienced customs broker or ask HMRC directly.
