Inventory valuation rules require ICDS aligned costing, inclusion of statutory levies, and category wise securities valuation for tax computation.
Inventory and securities for tax purposes must be valued in accordance with ICDS: inventory at the lower of actual cost or net realisable value, purchases, sales and inventory adjusted to include any tax, duty, cess or fee actually paid or incurred to bring goods or services to present location and condition; illiquid or unquoted securities at actual cost and regularly quoted securities at the lower of cost or NRV, with securities compared category wise and special treatment for scheduled banks and public financial institutions subject to prudential guidelines.
