Ghana'sAssociation of Independent Mobile Phone and Credit Dealers (ASIMODE) has called on the government to review the 20 pe cent import duty for mobile handsets, the Ghana News Agency reported. In a joint statement, the credit dealers said the tax could worsen the plight of mobile phone importers and dealers in this challenging investment environment. The statement noted that many members were already struggling with startup costs and unexpected liabilities. If the tax goes through, expenses associated with purchasing a handset could represent a high barrier to entry into the mobile market for many poorer Ghanaians. The mobile retail space was struggling since the market had largely reached saturation point, putting pressure on dealers to upgrade and renew.
