Cost recovery charges require custodians to pay for posted customs staff, with staffing norms, exemptions, and procedures. Custodians of notified Customs areas are required to bear the cost of Customs staff posted at those areas, with staffing norms prescribed by facility type and posts created/continued on a cost-recovery basis following proposals to DGHRD. Cost Recovery Charges are payable quarterly in advance, calculated as a uniform multiplier of the monthly average cost of the post plus allowances, with limited relief for delayed payment subject to interest and operational safeguards. Facilities meeting specified performance benchmarks may apply for exemption, which is subject to procedural conditions and may be withdrawn if benchmarks lapse; de-notification triggers pro rata adjustment and refund under financial rules.
