Cancellation of establishment registration requires closure details, settlement of worker dues, and hazardous chemical compliance certification. Application is prescribed for cancellation of the Registration Certificate of an establishment after closure of the establishment. It requires particulars such as the registration number, name and address of the establishment, employer details, communication address, and nature of work, along with intimation of the closure date. The employer must certify that all workers' dues have been paid and, where applicable, that the establishment is free from hazardous chemicals and substances before submission to the Registering Officer or Inspector-cum-Facilitator.
