Special warehouse licensing: eligibility and fitness requirements, and grounds for refusal including insolvency, conviction, or unsuitable site. Licensing requires applicants to be Indian citizens or registered entities, propose storage of goods notified under the relevant provision, furnish a solvency certificate (except government undertakings), submit an undertaking to comply with licence terms, and agree to pay supervision costs; the Principal Commissioner or Commissioner of Customs may refuse a licence for insolvency, conviction or penalisation, unsoundness of mind, pending bankruptcy or criminal proceedings, or if the proposed site is unsuitable for secured storage or customs supervision.
