Import-export prohibitions trigger confiscation and criminal penalties, and require compliance with EXIM policy, standards and licensing. Imports or exports made contrary to statutory prohibitions are liable to confiscation and penal measures under the Customs Act. The central government may notify goods as absolutely or conditionally prohibited for public policy reasons; prohibited goods include those failing to meet packaging, labelling or mandatory Indian Quality Standards, and exporters may be required to register with the Bureau of Indian Standards. Non-compliance with notified conditions renders goods prohibited and subjects persons to customs penalties and criminal liability for deliberate evasion.
