What is an HS code?

14 April 2026

When you import or export goods, you will quickly come across the term HS code. But what exactly is an HS code? An HS code (Harmonised System code) is an internationally standardised commodity code used to classify products worldwide for customs purposes.

This code forms the basis for import duties, VAT, and customs controls. Without the correct HS code, a shipment may be delayed or even rejected.

How does an HS code work?

An HS code consists of 6 digits and is used worldwide. These first six digits are the same in every country. Many countries add extra digits for further specification.

The structure is as follows:

  • First 2 digits: product category
  • Next 2 digits: subcategory
  • Last 2 digits: specific product group

Example: An HS code for shoes may start with 6403, which refers to leather footwear.

What is an HS code used for?

HS codes play a crucial role in international trade. They are used for:

  • Determining import duties and taxes
  • Performing customs checks
  • Collecting trade statistics
  • Verifying import and export regulations

The HS code is used on commercial invoices and customs documents for international shipments.

Why is the correct HS code important?

A mistake in the HS code may seem small, but often has direct consequences:

  • Incorrect import duties, leading to overpayment or additional charges
  • Delays at customs are impacting delivery times
  • Risk of fines due to incorrect declarations

That is why it is important to ensure the correct classification. In practice, this is often more complex than it seems, especially for combined or technical products. An HS code can be found via customs databases or verified by a logistics specialist.
