HS Code
Harmonized System Code
An HS code is a number that classifies a product for customs. It decides which duty rate and which rules apply to the goods.
In plain words
The Harmonized System is managed by the World Customs Organization (WCO) and is used by more than 200 countries and economies. The first 6 digits are the same worldwide. Each country then adds more digits for its own tariff: the EU uses 8 digits (CN), and Turkey uses 12 digits, called GTİP.
The importer is responsible for the right code, even when a customs broker prepares the declaration. A wrong code can mean the wrong duty, delays, fines, or problems with licences and trade agreements. If you are unsure, you can ask customs for a binding tariff decision before you import.
Example from real shipping
An importer brings in cotton T-shirts. The first 6 digits, 6109.10, mean “T-shirts, singlets and other vests, knitted or crocheted, of cotton” everywhere in the world. Turkish customs uses the full 12-digit GTİP to find the exact duty rate, and the broker writes this code on the declaration and the invoice.
