HS code meaning
The Harmonized Commodity Description and Coding System—usually shortened to the Harmonized System or HS—is the international framework used to classify traded goods. It is maintained by the World Customs Organization and used by more than 200 customs administrations and economies.
The first six digits provide the internationally recognised HS classification. Countries and customs unions can extend that structure to apply more detailed tariff and statistical measures.
HS, CN and TARIC: what is the difference?
For EU trade, the six-digit HS structure is extended by the eight-digit Combined Nomenclature, or CN. For imports, TARIC can extend the classification to ten digits and connects it with EU measures such as duty rates, suspensions, quotas, licences, anti-dumping measures and restrictions.
In practical terms, an ecommerce seller may hear ‘HS code’ used as a general phrase, but an EU import declaration can require the more detailed commodity code applicable to the particular product and transaction.
- HS: international six-digit foundation
- CN: eight-digit EU classification used for tariff and trade-statistics purposes
- TARIC: EU integrated tariff detail used for imports and applicable customs measures
Why the correct code matters
The commodity code helps determine the duty treatment and whether licences, controls or supporting documents apply. An inaccurate code can lead to delays, reassessment, extra charges, penalties or a request for more information.
Classification is based on what the item is made from, its function, how it is presented and the legal wording of the tariff—not simply the marketing name shown on a product page.
How to find a product code
Start with a precise product description, composition, intended use and technical specification. Search the EU TARIC and CLASS systems, review the relevant section and chapter notes, and confirm that the description covers the actual product.
When classification has significant commercial consequences or remains uncertain, an importer can seek professional customs advice or apply for Binding Tariff Information. A BTI decision provides legally binding classification certainty across the EU for the specified goods, subject to its conditions and validity.
- Describe the product accurately
- Record materials and percentages
- Identify its principal function
- Check TARIC measures and origin rules
- Keep the classification rationale with product records
HS codes in ecommerce fulfilment
Good product data should travel with every international order. Store the commodity code, country of origin, item value, weight and plain-language description against each SKU so customs documents can be generated consistently.
SmartShip can support the operational flow of declared product data, but the seller or importer remains responsible for ensuring that classification and customs information are accurate. Codes and tariff measures can change, so review them regularly.

Who is responsible for the code?+
The declarant and importer carry responsibility for accurate customs information, even when a carrier or fulfilment provider transmits it.
Where can I check an EU code?+
Use the European Commission’s TARIC and CLASS resources or seek a formal BTI decision where appropriate.
