The GST system in India relies on a Harmonized System of Nomenclature (HSN) to classify over 5,000 categories of goods. This HSN code helps streamline global trade and tax collection, ensuring smoother transactions. Whether you’re a business owner or a tax professional, understanding the HSN code is essential for managing GST compliance and avoiding misclassifications that could lead to penalties.
In this blog, we will explore the HSN code, its structure, implementation, and role in ensuring GST compliance, all while helping businesses streamline operations.
Overview of HSN Code
India has been a member of the World Customs Organization (WCO) since 1971, which developed the HSN for the systematic classification of goods in international trade. Initially, India used six-digit HSN codes to classify goods for Customs and Central Excise duties. In order to enhance the accuracy of these classifications, the Customs and Central Excise authorities later expanded the system to an eight-digit HSN code. This globally recognized system offers a standardized structure for taxation and trade documentation. It ensures accurate tax calculations and compliance with international trade regulations while also facilitating efficient cross-border transactions.
Now, let’s take a closer look at the structure of the HSN code, which offers a detailed and systematic framework for classifying goods.
Structure of HSN Code
The HSN code follows a hierarchical structure to ensure precise classification of goods. It consists of 21 sections, each covering a broad category of goods. These sections are further divided into 99 chapters, each representing different product categories. Within each chapter, 1,244 headings provide more specific classifications. Finally, each heading is further subdivided into 5,224 subheadings, offering detailed product-specific information. This organized structure ensures the efficient identification and classification of goods for international trade and taxation purposes.
In order to facilitate a clearer understanding of the structure, the HSN code can be outlined as follows:
- Chapter: The first two digits represent the chapter, which categorizes goods into broad groups. For example, 01 refers to “Live animals” under Chapter 1.
- Heading: The next two digits (3rd and 4th) represent the heading, which further narrows down the classification within the chapter. For example, 0101 refers to “Live horses, asses, mules, and hinnies” under Chapter 1.
- Sub-heading: The next two digits (5th and 6th) represent the sub-heading, which further specifies the goods. For example, 010121 refers to “Live horses” under heading 0101.
- Tariff Item: In India, an additional two digits (7th and 8th) are used for more specific classification of goods under national customs codes. For example, 01012100 refers to “Live horses, purebred breeding animals”.

The structured HSN code system facilitates accurate classification; on that basis, let us explore how these classifications are applied under the HSN code declaration rules under GST in India.
HSN Code Declaration Rules under GST
As per CGST Notification No. 78/2020, dated 15th October 2020, the HSN code declaration rules were updated, effective from 1st April 2021, based on the Annual Aggregate Turnover (AATO) of a business. For businesses with an AATO of up to ₹5 crore, declaring a 4-digit HSN code is mandatory for B2B tax invoices and optional for B2C tax invoices. However, businesses with an AATO exceeding ₹5 crore are required to declare a 6-digit HSN code for all invoices, whether B2B or B2C. The turnover of the previous financial year is used to determine the HSN code declaration requirement. Additionally, for exports and imports, it is mandatory to declare the full 8-digit HSN code to comply with international trade standards.
As per the Advisory on HSN Validation, taxpayers must report a minimum of 4 or 6 digits of the HSN Code in Table 12 of GSTR-1, depending on their AATO from the preceding financial year. These changes are being implemented in a phase-wise manner on the GST Portal, with Phase 2 having been implemented effective from 1st November 2022.
