KARACHI: The Directorate General of Customs Valuation is actively pursuing ‘Tanveer Plan’ and the development of database values and issuance of reference values of importable items have started yielding results. Director General Customs Valuation Syed Tanveer Ahmed devised a plan to streamline values of importable values to check under-invoicing, which is not only causing revenue loss to the exchequer, but it also has deprived the local manufacturing of level playing field. Directorate General of Customs Valuation has initiated an exercise to develop database values for different items wherein it has been observed that declarations are wide range and do not correctly reflect values of the items as traded in the international market. The reference values of Butyl Rubber (X_Butyl RB 301) under PCT 4002.3100 of Singapore are fixed at $1.75/kg, of Belgium at $1.8/kg. The reference values of Rectal Tube under PCT 9018 of China are fixed at $0.08/kg. The reference values of 3-way stopcock without tube Tube under PCT 9018 of China are fixed at $0.13/kg. The reference values of 3-way stopcock with 10cm tube Tube under PCT 9018 of China are fixed at $0.15/kg.
