🌟 Defining the Problem: Why GST and HSN Codes Matter for Solar Street Lights
The Question
What are the correct GST rates and HSN codes for solar street lights in India, and how do they impact businesses and consumers in the renewable energy sector?
The Hypothesis
Solar street lights, as composite systems comprising solar panels, batteries, LEDs, and controllers, are classified under HSN code 9405 and taxed at 12% GST, reflecting their role as renewable energy devices, with variations for components and services.
The Context
Solar street lights are self-contained systems that harness sunlight to provide nighttime illumination, reducing carbon footprints and energy costs. In India, GST—a unified tax system introduced in 2017—categorizes goods and services under HSN codes to standardize taxation. The HSN code, developed by the World Customs Organization, is an internationally accepted framework for classifying products, used by over 200 countries, including India. Correct classification ensures businesses charge the right tax, avoid penalties, and support India’s push for sustainable energy through favorable tax policies.
