| 2.    (d) Material Accounting policiesThe material accounting policies used in preparation of the standalone financial statements have been included inthe relevant notes to the standalone financial statements.
 Property, Plant and Equipment (PPE) are stated at cost, net of accumulated depreciation and accumulated impairment losses, if any.The cost comprises purchase price, including import duties and non- refundable purchase taxes, borrowing costs, if recognition criteria
 are met and any directly attributable cost of bringing the asset to its working condition for the intended use. Any trade discounts and
 rebates are deducted in arriving at the purchase price.
 Subsequent expenditure related to an item of PPE is capitalised only when it is probable that future economic benefits associated withthese will flow to the Company and the cost of the item can be measured reliably. Such cost includes the cost of replacing part of the
 plant and equipment. When significant parts of plant and equipment are required to be replaced at intervals, the Company depreciates
 them separately based on their specific useful lives. Likewise, when a major inspection is performed, its cost is recognised in the carrying
 amount of the plant and equipment as a replacement if the recognition criteria are satisfied. All other repair and maintenance costs are
 recognised in the Statement of Profit and Loss as incurred.
 Items of stores and spares that meet the definition of PPE are capitalized at cost. Otherwise, such items are classified as inventories.Catalysts which are used in commissioning of new plant are capitalized and are amortized based on the estimated useful life as technically
 assessed. Subsequent issues of catalysts, if any, are treated as inventory.
 Gains or losses arising from derecognition of the assets are measured as the difference between the net disposal proceeds and thecarrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.
 Depreciation on PPE is calculated using the straight-line method to allocate their cost, net of their residual values, over their useful livesestimated by the management based on technical evaluation, which are equal to the useful life prescribed under Schedule II to the
 Companies Act, 2013, other than the cases as mentioned in table below from S.No. (i) to (vi), where the useful lives are different from
 those prescribed in Schedule II to the Companies Act, 2013. The management believes that these estimated useful lives are realistic and
 reflect fair approximation of the period over which the assets are likely to be used. A major portion of the plant and equipment of the
 Company has been considered as continuous process plant.

 Capital Work-in-Progress (“CWIP”) As at March 31, 2025 (a) Ageing Schedule Note 4A : Other Intangible AssetsAccounting policy
Intangible assets acquired separately are measured on initial recognition at cost. Following initial recognition, intangible assets arecarried at cost less accumulated amortization and accumulated impairment losses, if any. Intangible assets with finite lives are amortised
 on a straight line basis over the estimated useful economic life. Software is the acquired intangible asset.
 Management of the Company assessed the useful life of software as finite and cost of software is amortized over its estimated useful lifeof five years on straight line basis.
 The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end ofeach reporting period. If the expected useful life of the asset is significantly different from previous estimates, the amortization period is
 changed accordingly. If there has been a significant change in the expected pattern of economic benefits from the asset, the amortization
 method is changed to reflect the changed pattern. Such changes are accounted for in accordance with Ind AS-8 "Accounting Policies,
 Changes in Accounting Estimates and Errors".
 Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds andthe carrying amount of the asset and are recognized in the Statement of Profit and Loss when the asset is derecognized.

 Note 8B : Trade ReceivablesAccounting Policy
 The Group recognises an allowance for expected credit losses (ECLs) for assets carried at amortised cost and FVOCI debt instruments.ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the
 Group expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include
 cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms. ECLs are recognised
 in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are
 provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit
 exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit
 losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL). For trade receivables, the
 Group applies a simplified approach in calculating ECLs. Therefore, the Group does not track changes in credit risk but instead recognises
 a loss allowance based on lifetime ECLs at each reporting date. The Group has established a provision matrix that is based on its historical
 credit loss experience, adjusted for forward-looking factors specific to the trade receivables and the economic environment. For debt
 instruments at fair value through OCI, the Group applies the low credit risk simplification.
 Contract Assets A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company fulfils itsperformance obligation by transferring goods or services to a customer before the customer pays consideration or before payment is
 due, a contract asset is recognised for the earned consideration that is conditional.
 Trade Receivables A receivable represents the company's right to an amount of consideration that is unconditional (i.e., only the passage of time is requiredbefore payment of the consideration is due).
 As per the records of the Company, including its register of shareholders / members, the above shareholding represents both legaland beneficial ownership of shares.
