Portland cement Slag cement White cement Oil-well cement Pozzolanic cement Clinker There is no reduced GST rate for cement used in affordable housing or government projects unless specially notified under contracts, not product classification.
Understanding Cement classification under GST Here’s what this really means:
The composition doesn’t matter as much as the product’s commercial identity. As long as it falls under “Hydraulic Cement, whether or not coloured or in the form of clinker,” the GST rate remains 28%. But classification errors still happen. Here are the common pitfalls.
Common classification mistakes 1. The mistaking of clinker and cement
Clinker is the raw material of cement production and falls under a different HSN Code (2523 10).
2. Improper Classification of cement with additives
When the product acts like cement, then that will remain below 2523 even in cases that involve the addition of things such as gypsum, fly ash, or slag.
3. Application of generic building material codes.
There is confusion in the use of Chapter 38 classifications (chemicals) of special cement mixes by some traders. This is dangerous and likely to attract notice.
4. To sell cement mortar or cement base as cement
These are in chapter 32 or 28, not 2523 When the product sets, hardens, and acts like cement, the product remains below 2523.
