Overtime fee for customs services enables post hours clearance and supervision upon payment, covering urgent or perishable consignments. Customs provides post hours or out of area supervision and clearance-including loading/unloading, stuffing/de stuffing, and cargo examination-only on payment of a Merchant Overtime Fee; the charge applies when trade requires services beyond normal working hours, on holidays, or at places outside Customs areas, notably for urgent consignments such as perishables or life saving drugs, and is collected under the statutory authority and accompanying fee regulations that prescribe rates and procedures.
