Merchant overtime recovery: new regulations define scope, require written requests, and impose revised fee and block charging rules. The Customs (Fees for Rendering Services by Customs Officers) Regulation, 1998, effective 15 October 1998, supersedes prior rules, defines 'Customs Officer', 'Customs work' and 'rendering services', prescribes revised hourly fee rates by officer category and time bands, requires written advance requests with fees payable by the requesting party, mandates a minimum three hour charge except for contiguous overtime, treats midnight-6 A.M. as a single block, and establishes before and after lunch blocks charged in full.
