Warehousing of imported goods allows deferred duty payment until clearance, subject to time limits and interest liability. The Customs Act, 1962 permits removal of imported goods to a warehouse without payment of duty, with duty payable on later clearance. The warehousing regime accommodates storage for market timing, supply to export or special economic units, and duty free shop stocking. Statutory time limits govern the permissible warehouse period during which no interest is charged, after which interest liability arises.
