What Is a Commodity Code?
A commodity code (also called an HS code or tariff code) is an 8- or 10-digit number that classifies your product for customs purposes. It determines:
- The rate of import duty you'll pay
- Whether VAT is payable at import
- Whether you need an import licence or certificate
- Whether anti-dumping duty applies
Getting the code wrong can mean overpaying duty, shipment delays, or penalties from HMRC.
How Many Digits?
| Code type | Digits | Used for |
|---|---|---|
| Harmonized System (HS) | 6 | International standard |
| UK commodity code | 8 | UK imports (EU-used before Brexit) |
| UK 10-digit code | 10 | Full UK tariff classification |
For most UK ecommerce imports, you need the 8-digit code. Some products require the full 10 digits.
How to Find Your Commodity Code
Step 1: Use the GOV.UK Trade Tariff
- Go to the GOV.UK Trade Tariff.
- Search by product name (e.g. “stainless steel water bottle”).
- Browse the classification tree.
- Note the 8-digit code and check the duty rate.
Step 2: Check the duty rate
- The tariff page shows the Third Country Duty rate (for non-EU imports).
- It also shows any preferential rates if the UK has a trade agreement with the source country.
Step 3: Confirm with your supplier
- Ask your supplier for the HS code they use. Cross-check it against the tariff — suppliers sometimes use the wrong code.
What If I Can't Find the Right Code?
If you're unsure:
- Use HMRC's Advance Tariff Ruling service for a legally binding decision.
- Contact a customs broker or freight forwarder (like Carrgo) to classify it for you.
- Request a Binding Tariff Information (BTI) ruling if you import the product regularly.

Common Mistakes
| Mistake | Risk |
|---|---|
| Using the supplier's code without checking | Could be wrong for UK imports |
| Using a 6-digit HS code only | Not specific enough for UK customs |
| Guessing the code | HMRC penalties, shipment delays, overpaid duty |
