Demurrage concession on delayed import air cargo encourages prompt clearance; partial waiver subject to timely removal under lockdown measures. One-time concession: airport and cargo terminal operators shall waive fifty percent of demurrage on import air cargo that landed on or after 20-03-2020, with Bills of Entry filed and lying in custodian warehouses with or without Customs Out-of-Charge, where delay in clearance is attributable to COVID-19 lockdown measures up to 14 April 2020, provided the cargo is cleared and removed by 23:59 hours on 16 April 2020; otherwise normal demurrage applies. No alternative or additional charges shall be imposed during this period.
