HSN code 2835 covers: Phosphinates (hypophosphites), phosphonates (phosphites), and phosphates; and polyphosphates, whether or not chemically defined.
After the 22 Sep 2025 reform most goods fall under 5% or 18% GST (a few sin/luxury items are 40%). We don't show an exact rate for this specific code because it isn't verified — check the CBIC rate finder or your CA, then enter that rate when you invoice.
Rates were revised in the 22 Sep 2025 GST reform (now a two-slab 5% / 18% structure for most goods, with a 40% slab for sin/luxury items). This is a reference, not tax advice — confirm the exact rate for your specific item with your CA.
