GST rate schedule amendments revise classification and valuation rules, reallocating goods across multiple tax slabs. The notification amends the State tax rate notification by adding reference to sub-section (5) of section 15 and revising entries across Schedule I (2.5%), Schedule II (6%), Schedule III (9%) and Schedule IV (14%). Changes include omissions, renumbering, substitutions, and insertions of tariff items (notably cork, marble, lithium-ion accumulators, video game consoles and vehicle parts), and an explanatory valuation rule deeming seventy per cent of gross consideration as the value of specified goods when supplied with a taxable service. Amendments take effect from 1st January, 2019.
