The HSN code is not typically used for work contracts, as work contracts are not considered goods or services. Instead, work contracts are typically classified according to the type of work being performed, the duration of the contract, and other relevant factors.
For example, a work contract for construction services might be classified under the "Construction Services" category, while a work contract for software development might be classified under the "Software Development Services" category.
Construction Services : HSN Code 9954
Software Development Services : HSN code 9983
