GST exemption for chena or paneer hinges on non pre packaged and non labelled supply, affecting labelling compliance. Exemption from integrated GST covers chena or paneer supplied other than as pre-packaged and labelled commodities; the expression is defined with reference to the Legal Metrology Act and rules for retail-intended pre-packed commodities subject to statutory declaration requirements and confined by an upper package size threshold. Amendments and clarifications exclude certain agricultural farm produce packaged beyond the retail threshold from the pre-packaged character, and separate provisions address unit containers bearing brand names and mechanisms for voluntarily foregoing actionable claims to retain exemption treatment.
