What is HS Code – Harmonized System (The complete Guide)

What is HS Code?

Harmonized Commodity Description and Coding System is commonly known as the HS Code or Harmonized System. The World Customs Organisation (WCO) has introduced and maintain the HS codes to identify products in international trade.

What is the use of Harmonized System Codes?

A language also has subgroups among its users. For example, native users of a language use different words to name the same product based on the region or the province they live in. When it comes to international trade different countries can have several names for the same product. In such situations, there can be disputes between shippers and consignees as well as among different authorities like the border control body. Due to the misunderstanding, there could be situations where the consignee receives goods differed from what he has ordered. Or the taxes differ from what has expected.

To avoid these types of miscommunications WCO has introduced one common language to identify goods in the international market, which is HS codes. When the consignee mentions the product with the HS code shipper knows exactly the consignee’s requirement so the customs officers. Normally HS code of the product mention under the BL description too for easy reference of the border controllers. This will keep both the customs officers and CHA‘s life at ease.

Border control bodies impose taxes and duties on the products by considering the HS code.

How to Classify Numbers in HS Code?

WCO has introduced 6 digits for a HS code. But they have allowed countries to have their national level subheadings after the 6 digits.
