What is an HS Code? How to Find and Use the Right HS Code in Exporting?

An issue encountered by exporting businesses but often not given enough importance is the inability to correctly choose the HS code of products. The wrong code can lead to consequences ranging from goods being delayed at customs to fines, or even smuggling investigations. In this article, we explain what the HS code is, how to search for it, and what you need to pay attention to for its correct use.

🚀 Quick Glance

• The HS code is your product's ID number at customs: This 12-digit code defines what the product is and which tax it is subject to.

• The first 6 digits are international, the remaining digits are specific to Turkey: The first half of the code is identical to the global HS Code.

• The code is determined by correct identification, not by application: An HS code is not requested from an institution; the correct category is found in the existing system based on the product's specifications.

• Risks of incorrect codes: Erroneous declarations can lead to consequences ranging from fines to smuggling investigations.

What is the HS Code?

The HS code (Customs Tariff Statistics Position), is a 12-digit code assigned to every product subject to export and import transactions, defining that product in international trade. The first 6 digits of this code are identical to the HS Code (Harmonized System) determined by the World Customs Organization and used globally; the remaining digits are additional digits added by Turkey according to its own legislation, containing details such as the product's material, purpose of use, and production method.

The HS code eliminates uncertainties arising from different languages and legislations of different countries, ensuring that customs procedures are carried out via a standard code instead of product names. Thus, instead of different definitions like "plastic container" or "storage container", a clear classification is made using a single code.

How to Search for the HS Code?

1. Clarify the Product's Technical Specifications

The first step to finding the correct code is to clarify what material the product is made of, what its intended use is, and whether it is a finished product or a semi-finished product. If this information is missing or unclear, the risk of falling into the wrong category increases.

2. Search via the TARİK System

The TARİK (Turkish Customs Tariff Schedule) system under the Ministry of Trade is the official search source for up-to-date HS codes. By entering the product description into the system, you can narrow down the relevant chapter, position, and sub-position step by step.

3. Take Codes of Similar Products as Reference

HS codes of similar products that have been previously imported or exported can be guiding. However, this method alone is not binding — even a minor difference in product specifications can cause the code to change.

Why is the HS Code So Important?

• It determines the customs duty rate: The taxes and financial obligations to be applied are calculated directly based on the HS code.

• It identifies prohibitions and restrictions: Certain products require special permits or documentation under specific HS codes.

• It ensures category alignment in e-exports: Marketplaces are increasingly basing their product listings on HS-based classifications.

Risks of Using the Wrong HS Code

In the mildest cases, an incorrect HS declaration leads to delays in goods at customs and additional costs. In more serious cases, if the product falls into the wrong category (for example, under the pharmaceutical chapter instead of food), this can become subject to investigation under the Anti-Smuggling Law. There is a similar risk with cosmetic products: using "therapeutic" claims on the packaging may classify the product as medicine rather than cosmetics and halt exports.

Special Cases

For some products, HS identification may require laboratory analysis depending on the composition of the product — especially for dietary supplements, cosmetics, or products with chemical content. In such products, determining the HS code based on technical/chemical analysis results rather than just looking at the product description prevents future penalty risks right from the start.

Conclusion: What You Need to Do

• Clearly define your product's technical specifications (material, purpose of use, production stage).

• Officially verify your HS code through the TARİK system.

• Get professional support from a customs broker for products you are not sure about.

• Review the HS code again when there are changes in product specifications.

❓ Frequently Asked Questions

1. What is the HS code and how many digits does it consist of?

The HS code (GTİP in Turkey) is a 12-digit classification code used in customs procedures for products. The first 6 digits are the same as the international HS Code, while the remaining digits include additional details specific to Turkey.

2. Is the HS code obtained from an institution?

No. The HS code is not a code given upon application; the equivalent of each product is already defined in the international classification system. What needs to be done is the correct identification of the most suitable code for the product.

3. Where can I search for the HS code?

The official and up-to-date search source is the TARİK (Turkish Customs Tariff Schedule) system under the Ministry of Trade.

4. What are the consequences of using the wrong HS code?

Consequences can range from delays of goods at customs, additional costs, and delays to investigations under the Anti-Smuggling Law if the product falls into the wrong category.

5. Is it enough to take the HS code of similar products as a reference?

No, it is not sufficient or binding on its own. Since even a small difference in product specifications can cause the code to change, product-specific verification must be conducted.
