How countries extend the HS code
The World Customs Organization (WCO) defines only the first 6 digits, which are identical worldwide. Every country then adds its own extra digits for tariff and statistical purposes.
Examples of national extensions
United States: 10‑digit HTS code (Harmonized Tariff Schedule)
Canada: 10‑digit HS‑10 import code (Customs Tariff + statistical suffix)
European Union: 8‑digit CN code (Combined Nomenclature)
India: 8‑digit ITC‑HS code (HSN for GST uses 6 digits)
Australia: 8‑digit Customs Tariff code
Japan: 9‑digit statistical code
China: 13‑digit CCCHS code (China Customs Commodity HS Code)
Key takeaway
HS‑10 exists in multiple countries, but each country’s 10‑digit structure is unique.
The only universal part is the HS‑6 level.
📦 Why countries extend beyond HS‑6
Countries add digits to:
Set national tariff rates
Define import/export controls
Collect detailed statistical data
Differentiate product variations not covered by HS‑6
This is why Canada’s HS‑10 and the U.S. HTS‑10 both have 10 digits but do not match each other beyond the sixth digit.
🧩 Comparison Table: HS Extensions by Country
Country Digits Name Purpose
Canada 10 HS‑10 Tariff item + statistical suffix
United States 10 HTS Tariff classification + statistical reporting
EU 8 CN Tariff + customs union classification
India 8 ITC‑HS Import/export classification; GST uses 6‑digit HSN
Japan 9 Statistical code National statistical detail
Australia 8 Customs Tariff Tariff classification
China 13 CCCHS Highly granular customs classification
All of these systems share the same first 6 digits, but diverge afterward.
⚠️ Important considerations
HS‑10 is not globally standardized—only the HS‑6 level is.
Two countries may both use 10 digits but classify differently beyond digit 6.
Duty rates are never determined by the HS‑6 alone; they depend on the country‑specific extension.
