GST classification clarifications: specify taxable rates and exemption treatment for pepper, raisins, popcorn, AAC blocks, and vehicle cess applicability. Clarification directs uniform GST treatment: pepper of genus Piper attracts the concessional pepper rate and dried pepper and raisins supplied by agriculturists are exempt from GST and not liable for registration; ready-to-eat popcorn mixed with salt and spices is taxed at a lower rate when not pre-packaged and at a higher rate when packaged and labelled, while sugar-coated popcorn is treated as confectionery at the higher rate and prior doubts on ready-to-eat popcorn are regularised for the past period; AAC blocks with majority fly ash attract the fly ash article rate; and the amended compensation cess entry applies from its stated effective date.
