Chapter 84 questions
What does HSN Chapter 84 cover?
Chapter 84 covers nuclear reactors, boilers, machinery and mechanical appliances; parts thereof. It contains 86 headings and 1,081 8-digit HSN codes.
Can I quote just the chapter number 84 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 84?
The schedule maps codes in this chapter to Nil, 5%, 12%, 18%, 28% 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 84?
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.
