Under GST, these are treated as services and classified using Service Accounting Codes instead of normal goods HSN codes. ## What is the HSN Code for Installation Services? For services, India uses SAC codes which are similar to HSN. Installation related services generally fall under: - **SAC 9987** for maintenance, repair and installation services - **SAC 9954** for construction services involving installation in buildings Which one you use depends on the nature of installation work. ## How Product Installation is Classified Under HSN (SAC)? When you install a product like an AC or machine at a customer location, the activity is usually covered under SAC 9987 if: - You are not constructing a building or civil structure - You are doing standalone installation or commissioning work - The main object is to fix or start the equipment at site If the installation is part of a bigger construction project, the same work may be treated as part of works contract under SAC 9954. ## Home Installation Services and Their HSN Code Typical home installation services include: - Air conditioner fitting - Geyser installation - RO and water purifier installation - TV wall mounting and similar services Most of these household installation jobs are billed under SAC 9987. Many businesses mention 9987 on invoices for such services and charge standard GST. ## GST Implications on Installation Services Under GST, installation services are usually taxable at the standard rate unless a special exemption or concessional rate is given. For most installation work: - GST is **18 percent** - The same rate applies to labour charges for installation - Material used may be taxed separately if billed separately If the installation forms part of a composite supply with goods, you must see whether the principal supply is goods or service and classify accordingly. ## Installation SAC Code Classification and GST Rates Here are some commonly used HSN codes and GST rates for this category ### 4 Digit SAC Code Classification | **HSN/SAC Code** | **HSN/SAC Code Title** | **GST Rate** | | --- | --- | --- | | [**9954**](https://busy.in/sac-code-9954/) | Other construction services | **18%** | | [**9987**](https://busy.in/sac-code-9987/) | (i) Services by way of housekeeping, such as plumbing, carpentering, etc. where the person supplying such service through electronic commerce operator is not liable for registration under sub-section (1) of section 22 of the Central Goods and Services Tax Act, 2017. | **5 – No ITC** | ### 6 Digit SAC Code Classification | **HSN/SAC Code** | **HSN/SAC Code Title** | **GST Rate** | | --- | --- | --- | | **995434** | Water well drilling services and septic system installation services | **18%** | | **995441** | Installation, assembly and erection services of prefabricated buildings | **18%** | | **995442** | Installation, assembly and erection services of other prefabricated structures and constructions | **18%** | | **995443** | Installation services of all types of street furniture (e.g., bus shelters, benches, telephone booths, public toilets, etc.) | **18%** | | **995444** | Other assembly and erection services n.e.c. | **18%** | | **995455** | Structural steel erection services | **18%** | | **995461** | Electrical installation services including Electrical wiring & fitting services, fire alarm installation services, burglar alarm system installation services. | **18%** | | **995463** | Heating, ventilation and air conditioning equipment installation services | **18%** | | **995464** | Gas fitting installation services | **18%** | | **995466** | Lift and escalator installation services | **18%** | | **995468** | Other installation services n.e.c. | **18%** | | **995469** | Services involving Repair, alterations, additions, replacements, maintenance of the installations covered above. | **18%** | | **998731** | Installation services of fabricated metal products, except machinery and equipment. | **18%** | | **998732** | Installation services of industrial, manufacturing and service industry machinery and equipment. | **18%** | | **998733** | Installation services of office and accounting machinery and computers | **18%** | | **998734** | Installation services of radio, television and communications equipment and apparatus. | **18%** | | **998735** | Installation services of professional medical machinery and equipment, and precision and optical instruments. | **18%** | | **998736** | Installation services of electrical machinery and apparatus n.e.c. | **18%** | | **998739** | Installation services of other goods n.e.c. | **18%** | \* GST rates may vary based on the latest GST notifications ## About the author **Madan Murari** Hi there!
