If you import or export goods, using the correct commodity code is a legal requirement.
Commodity codes determine:
Customs duties
Import VAT
Trade restrictions
Licensing requirements
Quotas and special measures
Using the wrong code can result in shipment delays, additional charges, penalties, or customs audits. This MyParcels guide explains what commodity codes are, how they are structured, and where to find the correct one depending on your location.
What Is a Commodity Code?
A commodity code is a numerical classification used to identify goods for international trade.
It is required when completing:
Customs declarations
Commercial invoices
Export documentation
Import paperwork
Commodity codes may also be called:
Tariff codes
Customs tariff numbers
Classification codes
HS codes (Harmonised System codes)
Why Commodity Codes Matter
Correct classification ensures:
Accurate duty and VAT calculations
Proper customs clearance
Compliance with trade regulations
Faster border processing
Reduced risk of penalties
If you are listed as the Importer of Record, you are legally responsible for the accuracy of the declaration — even if a courier, customs agent, or supplier provides the code.
What Information Do You Need?
To identify the correct commodity code, you must understand your product in detail.
You should know:
What the product is and its main purpose
What it is made from (full material breakdown)
Technical specifications
How it is packaged or presented
Whether it is unfinished or unassembled
Accurate product descriptions are essential for correct classification.
How Commodity Codes Are Structured
Commodity codes are built in layers.
The First Six Digits – Harmonised System (HS)
The first six digits are internationally recognised under the Harmonised System.
They break down into:
First 2 digits → Chapter (broad category)
Next 2 digits → Heading (product group)
Next 2 digits → Subheading (more specific classification)
These six digits are standard worldwide.
Additional Digits – Location Matters
After the first six digits, the code may be extended depending on where you are based and whether you are importing or exporting.
UK Mainland | Ireland | Northern Ireland |
The UK Trade Tariff applies to goods entering Great Britain. | Ireland follows the EU Combined Nomenclature (CN) and TARIC system.
The EU TARIC system determines duties, VAT rules, and trade measures. | Northern Ireland follows different rules depending on the movement of goods:
Commodity codes are generally:
Businesses should check whether UK or EU tariff rules apply to their specific movement of goods. |
Commodity Code Extensions
Some products require additional codes beyond the standard 8 or 10 digits.
EU (Ireland & Northern Ireland for EU movements)
TARIC may apply additional digits for specific trade measures
Some products require a TARIC Additional Code (4 extra digits)
This applies to anti-dumping duties, quotas, or licensing controls
UK Mainland
Certain imports may require:
Additional UK tariff codes
Trade remedy references
Licensing identifiers
These are declared separately when required.

What Is Binding Tariff Information (BTI)?
A Binding Tariff Information ruling:
Confirms the correct commodity code
Is legally binding
Is valid for 3 years
Provides certainty for duties, VAT, quotas and licensing
It is free to apply for, though laboratory testing costs may apply.
BTI is the only way to obtain official, legally binding confirmation of your product classification.
Common Classification Mistakes
Relying only on supplier-provided codes
Using outdated EU codes for UK imports
Copying similar product codes
Failing to consider material composition changes
Not reviewing codes after annual updates
Incorrect codes can result in:
Financial penalties
Delayed shipments
Incorrect duty payments
Customs audits
