Last reviewed: 30 September 2026
Simple definition
An international goods-classification code maintained by the WCO at six-digit level.
Detailed explanation
The Harmonized System organises traded goods into sections, chapters, four-digit headings and six-digit subheadings. National tariffs can add further digits. Classification requires the product's objective characteristics and the applicable interpretative rules; a general product name alone is not enough.
Example
A trader identifies a six-digit HS subheading, then checks the destination tariff for its national commodity-code extension.
