GST rate amendments reclassify and reallocate specified goods across rate schedules, altering tariff treatment and product-specific taxation. Amendments to the principal notification under the Central Goods and Services Tax Act revise multiple rate Schedules by inserting, substituting and omitting entries to reclassify specified goods. Key changes add tamarind kernel powder, mehendi paste in cones, rice bran, household LPG entries, bio-pesticides, biodiesel, sugar boiled confectionery, drinking water in 20-litre bottles, irrigation and spraying equipment, cigarette filter rods, bamboo joinery, sanitary ware, and reclassify precious and semi-precious stones and imitation jewellery, while substituting and omitting several earlier schedule entries.
