Chapter 28 questions
What does HSN Chapter 28 cover?
Chapter 28 covers inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes. It contains 50 headings and 323 8-digit HSN codes.
Can I quote just the chapter number 28 on an invoice?
No. GST reporting needs at least the 4-digit heading (turnover up to Rs. 5 crore) or the 6-digit subheading (above Rs. 5 crore), and customs documents need all 8 digits. Use the chapter only to navigate to the exact code.
What GST rates apply in Chapter 28?
The schedule maps codes in this chapter to 5%, 12%, 18% slabs, depending on the exact product. Open a code page for its specific rows and CGST/SGST split, and verify the current rate on the CBIC GST portal before filing.
Do I need GST registration to sell goods from Chapter 28?
GST registration is required once your aggregate turnover crosses the threshold that applies to your state and supply type, or earlier for activities like inter-state supply or selling through e-commerce operators. IncorpX provides assistance for GST registration and can help you check whether the requirement applies to your business.
