Valuation of Second-Hand Machinery for Customs is the process of determining the fair assessable value of imported used machinery for customs duty assessment. The valuation is generally carried out by a Chartered Engineer (CE) or a qualified Valuer Engineer, who inspects the machinery and certifies its condition, age, residual life, and current market value. Customs authorities use this information, along with applicable customs valuation rules, to assess the import value and calculate duties.
