The Ministry of Finance has launched a new tariff book – a price index of 8,000 international import items used to determine customs duty rates. The major change is that the revised book includes duty rates for specific products whereas the previous version applied rates to categories. Lowered tariffs on spare parts for locally-assembled products and raw materials for manufacturers have been granted in the new book. The revision process was conducted by a committee composed of members from the ministries of Finance, Trade & Industry, and Revenues along with the Customs Commission. The revisions are compatible with the tariff book used by the World Customs Organisation (WCO), which has 183 members, including Ethiopia.
