Why are HSN codes required? Because the HSN codes, which are known as the “Harmonised System of Nomenclature code”, are a commonly used classification scheme for goods under the GST regime in India and other countries. Businesses can give products unique identifiers for taxation, compliance, and international trade purposes by using HSN codes. They were created to streamline and standardise trade procedures.
In addition to HSN, SAC (Services Accounting Code) and UQC (Unit Quantity Code) are important terms for GST filing and invoicing. Every business owner, trader, and tax expert must comprehend the structure of HS codes, their significance, and how to locate them precisely.
In this guide, we'll go over the HSN codes in detail, including the HS code search, HSN code list, descriptions, SAC codes, and how to find the HSN code for the product from Seair Exim Solutions.
The Harmonized System of Tariff Nomenclature, sometimes referred to as the Harmonized Commodity Description and Coding System, is a globally standardized system of names and numbers used to categorize traded goods.
The six-digit uniform HSN code is used to categorize over 5000 products and is recognized globally. The World Customs Organization (WCO) created it, and it became operative in 1988.
Additionally, by giving customs officers and companies around the world a common language, the HS system streamlines international trade. This system is used to classify more than 98% of the goods that are traded internationally.
In India, the conventional 6-digit HS code is expanded to an 8-digit code for a more thorough classification. The structure of the code is hierarchical and logical.
The HSN code follows a hierarchical structure designed to classify goods in increasing detail. It begins with a 2-digit chapter number, followed by a 4-digit heading, a 6-digit sub-heading, and, in India, an 8-digit tariff item for more specific identification under GST. This logical format helps businesses and tax authorities accurately categorize products for compliance, import-export, and tax purposes.
The following example shows the structure of an HSN code list for a common product, such as tomatoes:
| Hsn Codes List | Hsn Code Description | Classification Level |
| 7 | Edible vegetables and certain roots and tubers | Chapter (2 digits) |
| 702 | Tomatoes, fresh or chilled | Heading (4 digits) |
| 70200 | Tomatoes, fresh or chilled (no further sub-classification at the 6-digit level) | Sub-heading (6 digits) |
| 7020001 | Tomatoes (for Indian-specific classification) | Tariff Item (8 digits) |
For a more detailed breakdown and to search HS codes, service charge HS code or HSN numbers, please visit the HS Codes section on the Seair website.
The HSN system is divided into 21 sections and 99 chapters, each representing a broad category of goods such as live animals, vegetable products, or machinery. Within each chapter, goods are further classified into headings and sub-headings. This chapter-wise breakdown makes it easier for traders, manufacturers, and GST professionals to locate the correct HSN code based on product type and industry.
| Chapter | HSN code description |
| 15 | Animal or vegetable fats and oils and their cleavage products; prepared edible fats; animal or vegetable waxes |

The main difference between HSN and SAC codes is that HSN codes are meant only specifically for goods and services, and SAC codes specify services only.
Another difference is in the number of digits in their code and their relevance. Example—The HSN Code is an 8-digit code, and the SAC code is a 6-digit code.
We will now examine what the Service Accounting Code (SAC) means.
Under India's Goods and Services Tax (GST) system, services are categorised using the Services Accounting Code (SAC). For taxation purposes, it is a special six-digit code that is used to classify and identify various services.
The Indian government uses the SAC HSN Code as a classification system to categorise and tax the different services that companies offer. The type of service being provided and the relevant GST rate are determined by the SAC HSN Code.
To find the correct SAC HSN Code, HSN number search or HSN codes list, you can use the Seair portal's search function, consult our data expert resources or obtain the list of HSN Codes or SAC HSN Code.
A standardised code system called a Unit Quantity Code, or UQC, is used to indicate the units of measurement for products and services. Under the Goods and Services Tax (GST) regime in India, they are essential for guaranteeing consistency and precision in reporting amounts across a range of commercial transactions.
UQCs are utilised in a number of GST framework components, such as HSN summaries, e-way bills, tax invoices, and GST returns (such as GSTR-1, GSTR-2, and GSTR-3B). For example, instead of using terms like "bottles," the UQC code BTL is used
In India's GST regime, HSN (Harmonised System of Nomenclature) codes play a crucial role in classifying goods for taxation, compliance, and streamlining various processes.
Here's why HSN is important under GST:
Standardised Classification: HSN offers a methodical and rational approach to grouping products according to their attributes, composition, purpose, and place of origin.
Accurate Tax Rate Determination: A particular GST rate is associated with each HSN code. Businesses can lower the possibility of mistakes in tax computations and guarantee that the correct amount of tax is paid by accurately determining the applicable GST rate for their products using the correct HSN code.
The Harmonized System of Nomenclature (HSN) codes are dynamic and subject to revision, especially when it comes to policy conditions and GST rates.
The Central Board of Indirect Taxes & Customs (CBIC) and the Directorate General of Foreign Trade (DGFT) periodically publish notifications with updates, but there isn't an updated "Latest HSN Codes List" with a direct download link on a central government website.
However, you can look for a downloadable list by visiting online trade portals like Seair Exim Solutions, which frequently offer up-to-date HSN code lists with updated export-import data.
As of 2025, India follows an 8-digit HSN structure aligned with the latest international HS amendments and GST rate rationalisation. Here are the Important Updates of 2025:

It is difficult to find a definitive list of the "top 880 used codes" because usage differs depending on the industry. On the other hand, information about import-export transactions can provide a sense of commonly used codes.
Here are some examples of HSN codes and how they are used in different industries:
| Hsn Codes List | Hsn Code Description | Sector |
| 9021 | Orthopaedic appliances and fracture appliances | Medical Devices |
| 9506 | Articles and equipment for sports, games, and recreation | Sports Goods |
| 7323 | Table, kitchen, or other household articles of iron or steel | Household Goods |

| 8308 | Clasps, buckles, hooks, and similar articles | Leather Goods |
| 3926 | Other articles of plastics and articles of other materials | General Manufacturing |
Understanding the difference between SAC and HSN codes is essential. While SAC codes (Services Accounting Codes) are used to classify services, HSN codes are used to classify goods. Consequently, you will need to consult SAC codes for industries such as insurance and other services.
| Hsn Codes List | Hsn Code Description |
| 101 | Live horses, asses, mules, and hinnies |
| 713 | Dried leguminous vegetables, shelled |
| 1006 | Rice |
| 1209 | Seeds of a kind used for sowing |
| 3105 | Other fertilisers |
