FAQs on Harmonized System (HS) Code

  • A Harmonized System (HS) code is a standardized numerical code used worldwide to classify goods in international trade. It is managed by the World Customs Organization and is used by customs authorities in over 200 countries to identify products, calculate duties and taxes, and collect trade statistics.

  • Yes, HS codes are used for both import and export because they are the common language customs authorities rely on to classify goods in international trade. The same six‑digit HS structure underpins the classification systems that countries use when goods enter (imports) or leave (exports), and it appears on key documents like customs declarations, commercial invoices, and certificates of origin.

  • The HS code is a 6-digit classification used by over 200 countries to pin-down products. On the other hand, an HTS code is specific to your country - like the US - and throws in 2 to 4 extra digits onto the base HS code to figure out duty rates and trade stats. When you are shipping internationally, the first 6 digits are the same everywhere, but the rest of the code changes depending on where your goods are headed.

  • The first 6 digits are the standard set by the World Customs Organization (WCO). That means no matter where you are in the world, these 6 digits are just about the only thing you'll see the same everywhere. They amount to a sort of "customs language". Now the full 10-digit code is all about how much duty you pay in a particular country but the 6 digits make sure your cargo isn't caught for basic misclassification at the border.

  • If you get the code wrong your shipment is more likely to get "flagged" by customs. The upshot is either a delay while they re-check the cargo, or heavy fines for the person importing the goods, seizure of the goods, or needing to pay for the duty all over again after the fact. For a freight forwarder, getting the code wrong can damage your reputation and lead to all sorts of insurance headache.

  • The WCO usually only updates the HS nomenclature every five years to keep up with the HS/HSN Codes FAQ Content Sample latest and greatest. They last did it in 2022. However countries update their own HTS tariff schedules much more often. They can do it as often as once a year, or even half a year if there are new trade agreements or if a country decides to impose a "Section 301" style tariff.

  • Not exactly. An HS code is the global base classification (usually 6 digits) created by the World Customs Organization, and it is the same across all participating countries. A tariff code is usually the full national classification used by a specific country to set duties and taxes, and it typically starts with the HS code and then adds extra digits for local detail. So every tariff code is built on an HS code, but it is more specific to one country’s tariff schedule.
