Issue 1: Classification under HSN 3214 90 10
The Applicant sought an Advance Ruling on the proper classification of their product, "SIKA Block Joining Mortar," under HSN 3214 90 10. The product is described as a Grey Cement based non-shrink, self-curing water resistance mortar for fixing AAC Blocks, Concrete Blocks, Fly Ash Bricks, etc. The Applicant provided details of similar products classified under HSN 3824 50 90 by competitors. The CESTAT order directed a re-examination of the classification, emphasizing that products like cement, grout, and repair mortar may not fall under subhead 3214. However, the Commissioner (Appeals) in Goa classified a similar product under tariff item 3214 90 90. The CEGAT in Mumbai also classified ready-mix plasters under subhead 3214.

The decision ruled that "SIKA Block Joining Mortar" should be classified under tariff item 3214 90 90, making it taxable under specific provisions of the CGST Act, 2017 and WBGST Act, 2017. The ruling is valid unless declared void under the relevant provisions of the GST Act.
