What Are HS Codes?
The Harmonized System (HS) is a standardised numerical system for classifying internationally traded products, maintained by the World Customs Organization (WCO). Over 200 countries use the HS as the basis for their customs tariffs and trade statistics.
The system classifies approximately 5,613 commodity groups using 6-digit codes, organised into 21 sections and 97 chapters. The first 6 digits are internationally harmonised — meaning code 090111 refers to the same product (unroasted, non-decaffeinated coffee) in every country in the world.
How HS Codes Are Structured
Sections (21, Roman numerals) → Chapters (97, 2-digit) → Headings (1,229, 4-digit) → Subheadings (5,613, 6-digit). Countries add digits beyond 6 for their own tariff schedules (UK uses 10 digits, US uses 10 digits, EU uses 8–10 digits).
Why HS Codes Matter
HS codes determine: customs duty rates, import/export restrictions, trade statistics, and regulatory compliance. Incorrect classification can result in wrong duty payments, customs delays, seized goods, or fines. Every commercial invoice for international trade must include the correct HS code.
