Baggage examination rules govern landing and clearance of passenger baggage, with firearms import limits requiring commissioner permission. Customs rules require examination and passing on board of cabin baggage not in sealed cases, including official uniforms and authorised arms on declaration; baggage passed as free may be landed at any bunder. Other baggage must be landed at the Passenger Pier and cleared on production of keys, a signed declaration and payment of duty; articles in commercial quantities are sent to the Customs House for appraisement. Firearms beyond permitted personal limits require permission of the Principal Commissioner or Commissioner of Customs.
